Accounting Policies	2. Accounting Policies Basis of Presentation The accompanying interim consolidated balance sheet as of September 30, 2018, and the related consolidated statements of operations and comprehensive loss and cash flows for each of the three and nine months ended September 30, 2018 and 2017, are unaudited. The unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted. In the opinion of management, the accompanying unaudited consolidated financial statements for the periods presented reflect all adjustments which are normal and recurring, and necessary to fairly state the financial position, results of operations, and cash flows of the Company. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 filed with the SEC on March 30, 2018 and amended April 17, 2018. Intercompany balances and transactions have been eliminated in consolidation. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2018. Recently Issued Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Revenue Recognition We currently report our net revenues under two operating groups: Wireless and Graphics. Generally, we recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed and determinable, and collectability is probable. We recognize revenues from sales of our software (or software that we are licensed to distribute) to our customers or end users as completed products are shipped and title passes, or from royalties generated as authorized customers duplicate our software, if the other requirements are met. If the requirements are not met as of the date of shipment, revenue is not recognized until these elements are known or resolved. For Wireless, we recognize revenue using several different methods beyond the method previously mentioned. First, we provide some customers a subscription service arrangement (the “Platform”). This Platform is then deployed to their customers, the end users, either directly by our customer or by the end user initiating a download of the Platform. Our service arrangement can include the use of the software application, hosting services, and maintenance and support services for the Platform. This type of arrangement is recognized on a point in time basis separately for each billing cycle (i.e. monthly or quarterly) based on the individual metrics within that period, and results in either a fixed fee per end user or a revenue sharing arrangement based on amounts received by our customers. Second, we provide other related services to some customers specific to hosting services, and maintenance and support services. These arrangements are recognized on a per period basis (i.e. typically monthly or quarterly) based on the individual arrangements agreed upon with our customers. These arrangements typically include a fixed fee for services offered within the period. Sometimes these types of services include up-front, non-refundable set-up fees. Revenue is recognized for these fees over the term of the agreement. Third, we provide a limited custom software development services under a fixed fee arrangement. This revenue is recognized based on agreed-upon deliverables and milestones – when value is provided to the customer a portion of the revenue is recognized. There are no significant judgments required for this revenue. However, we do make some estimates to accrue revenue through the fiscal quarter ends. For Graphics, we review available retail channel information and make a determination of a return provision for sales made to distributors and retailers based on current channel inventory levels and historical return patterns. Certain sales to distributors or retailers are made on a consignment basis. Revenues for consignment sales are not recognized until sell-through to the final customer is established. Certain revenues are booked net of revenue sharing payments. Sales directly to end users are recognized upon shipment. End users have a thirty-day return period, but such returns are reasonably estimable and have historically been minimal. We also provide technical support to our customers. Such costs have historically been insignificant. Deferred revenue represents amounts billed to customers for which revenue has not been recognized. Deferred revenue primarily consists of the unearned portion of monthly, quarterly and annually billed service fees and prepayments made by customers for a future period. Revenues on a disaggregated basis are as follows (in thousands): For the Three Months Ended September 30, For the Nine Months Ended September 30, 2018 2017 2018 2017 (unaudited) (unaudited) Wireless: Software $ 48 $ 193 $ 311 $ 264 Platform 5,908 3,603 15,780 10,858 Services 339 593 1,406 1,954 Contract (12 ) 301 108 602 Total wireless $ 6,283 $ 4,690 $ 17,605 $ 13,678 Graphics: Software 242 1,114 1,328 3,564 Total revenues $ 6,525 $ 5,804 $ 18,933 $ 17,242 Fair Value Measurements The Company measures and discloses fair value measurements as required by FASB Accounting Standards Codification (“ASC”) Topic No. 820, Fair Value Measurements and Disclosures Fair value is an exit price, representing the amount that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: • Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets • Level 2 - Include other inputs that are directly or indirectly observable in the marketplace • Level 3 - Unobservable inputs which are supported by little or no market activity The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. As required by FASB ASC Topic No. 820, we measure our cash and cash equivalents at fair value. Our cash equivalents are classified within Level 1 by using quoted market prices utilizing market observable inputs. As required by FASB ASC Topic No. 820, we measure our warrant liability at fair value. Our warrant liability is classified within Level 3 as some of the inputs to our valuation model are either not observable quoted prices or are not derived principally from, or corroborated by, observable market data by correlation or other means. As required by FASB ASC Topic No. 820, we utilize quoted market prices to estimate the fair value of our fixed rate debt, when available. If quoted market prices are not available, we calculate the fair value of our fixed rate debt based on a currently available market rate, assuming the loans are outstanding through maturity and considering the collateral securing the loans. In determining the current market rate for fixed rate debt, a market spread is added to the quoted yields on federal government treasury securities with similar terms to the debt.

Going Concern Evaluation

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Going Concern Evaluation	3. Going Concern Evaluation In connection with preparing consolidated financial statements for the three and nine months ended September 30, 2018, management evaluated whether there were conditions and events that, when considered in the aggregate, raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the historical operating loss and negative cash flow from operating activities trends. Ordinarily, conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern relate to the entity’s ability to meet its obligations as they become due. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following: • In May 2017, the Company raised $2.2 million of new capital in a private placement offering of its common stock. • In September 2017, the Company closed on a $5.5 million preferred stock transaction which converted $2.8 million of long and short-term debt, and raised $2.7 million of new capital. • On March 5, 2018, the Company raised $5.0 million of new capital in a private placement offering of its common stock. • On May 3, 2018, the Company raised $7.0 million of new capital in a private placement offering of its common stock. In addition to the recent capital raised, management also believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months from the issuance date. The Company will take the following actions, if it starts to trend unfavorably against its internal profitability and cash flow projections, in order to mitigate conditions or events that would raise substantial doubt about its ability to continue as a going concern: • Raise additional funds through short-term loans. • Implement additional restructuring and cost reductions. • Raise additional capital through a private placement. • Secure a commercial bank line of credit. • Dispose of one or more product lines. • Sell or license intellectual property.

Debt and Fair Value of Financial Instruments	5. At September 30, 2018 and December 31, 2017, the carrying value and the aggregate fair value of the Company’s warrant liability and short- and long-term debt were as follows (in thousands): As of September 30, 2018 As of December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Warrant liability $ 9,918 $ 9,918 $ — $ — Short-term debt, related party — — 1,000 1,000 Long-term debt, related party 1,200 1,200 1,200 1,200 Long-term debt 1,755 1,755 1,558 1,558 Total $ 12,873 $ 12,873 $ 3,758 $ 3,758 The warrants were accounted for as liabilities, with changes in the fair value included in net loss for the respective periods. Because some of the inputs to our valuation model were either not observable or not derived principally from or corroborated by observable market data by correlation or other means, the warrant liability is classified as Level 3 in the fair value hierarchy. Our stock price can be volatile and there could be material fluctuations in the value of the warrants in future periods. A roll forward of our warrant liability classified as Level 3 and measured at fair value on a recurring basis follows (in thousands): Balance at December 31, 2017 (audited) $ — Warrants issued 6,792 Change in fair value of warrant liability 3,126 Balance at September 30, 2018 (unaudited) $ 9,918 Warrant Liability As further discussed in Note 10, on March 6, 2018, the Company completed a private placement with several investors (the “March Offering”), wherein a total of 2,857,144 shares of the Company’s common stock were issued at a purchase price of $1.75 per share, for a total purchase price of $5.0 million. Each investor also received a warrant to purchase up to a number of shares of common stock equal to the number of shares of common stock purchased by such investor in the March Offering at an exercise price of $2.17 per share. The initial fair value of the warrant liability associated with the March Offering was $2.9 million, and the fair value has increased to $4.7 million as of September 30, 2018. As further discussed in Note 10, on May 3, 2018, the Company completed a private placement with several investors (the “May Offering”), wherein a total of 3,170,000 shares of the Company’s common stock were issued at a purchase price of $2.21 per share, for a total purchase price of $7.0 million. Each investor also received a warrant to purchase up to a number of shares of common stock equal to the number of shares of common stock purchased by such investor in the May Offering at an exercise price of $2.11 per share. The initial fair value of the warrant liability associated with the May Offering was $3.9 million, and the fair value has increased to $5.2 million as of September 30, 2018. All changes in the fair value of warrants will be recognized in our consolidated statements of operations until they either are exercised or expire. The warrants are not traded in an active securities market and, as such, the estimated fair value as of September 30, 2018 was determined by using an option pricing model (Black-Scholes) with the following assumptions: March 5, 2018 May 3, 2018 Warrants Warrants Expected term 4.92 5.08 Common stock market price $ 2.52 $ 2.52 Risk-free interest rate 2.89 % 2.89 % Expected volatility 70.6 % 74.0 % Resulting fair value (per warrant) $ 1.58 $ 1.66 Expected volatility is based on historical volatility. Historical volatility was computed using monthly pricing observations for recent periods that correspond to the expected term of the warrants. We believe this method produces an estimate that is representative of our expectations of future volatility over the expected term of these warrants. We currently have no reason to believe future volatility over the expected remaining life of these warrants is likely to differ materially from historical volatility. The expected life is based on the remaining contractual term of the warrants. The risk-free interest rate is the U.S. Treasury bond rate as of the valuation date. Debt On January 30, 2018, the Company amended certain of its existing Secured Promissory Notes (the “Notes”) for the sole purpose of extending the relevant maturity dates. The Note dated August 18, 2017 issued to Steven L. Elfman and Monique P. Elfman was amended to extend its maturity date to February 11, 2018 and was subsequently paid in full. The Note dated June 26, 2017 issued to William W. Smith, Jr. and Dieva L. Smith was amended to extend its maturity date to July 25, 2018. The Notes dated August 24, 2017 issued to Next Generation TC FBO Andrew Arno IRA 1663 and Andrew Arno were amended to extend the maturity date of each to July 25, 2018. As a condition to closing of the March Offering, the following Notes were further amended for the sole purpose of extending the maturity dates of each to March 25, 2020: (i) Secured Promissory Note dated June 26, 2017, issued to William W. Smith and Dieva L. Smith, as amended; (ii) Secured Promissory Note dated August 24, 2017, issued to Next Generation TC FBO Andrew Arno IRA 1663, as amended; and (iii) Secured Promissory Note, dated August 24, 2017 issued to Andrew Arno, as amended.

Commitments and Contingencies	9. Commitments and Contingencies Litigation The Company may become involved in various legal proceedings arising from its business activities. While management does not believe the ultimate disposition of these matters will have a material adverse impact on the Company’s consolidated results of operations, cash flows, or financial position, litigation is inherently unpredictable, and depending on the nature and timing of these proceedings, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows, or financial position in a particular period. Other Contingent Contractual Obligations During its normal course of business, the Company has made certain indemnities, commitments, and guarantees under which it may be required to make payments in connection with certain transactions. These include: intellectual property indemnities to the Company’s customers and licensees in connection with the use, sale, and/or license of Company products; indemnities to various lessors in connection with facility leases for certain claims arising from use of such facility or under such lease; indemnities to vendors and service providers pertaining to claims based on the negligence or willful misconduct of the Company; indemnities involving the accuracy of representations and warranties in certain contracts; and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware. In addition, the Company has made contractual commitments to employees providing for severance payments upon the occurrence of certain prescribed events. The Company may also issue a guarantee in the form of a standby letter of credit as security for contingent liabilities under certain customer contracts. The duration of these indemnities, commitments, and guarantees varies, and in certain cases may be indefinite. The majority of these indemnities, commitments, and guarantees may not provide for any limitation of the maximum potential for future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities, commitments, and guarantees in the accompanying consolidated balance sheets.

Equity [Abstract]
Equity Transactions	10. Equity Transactions March 2018 Offering On March 6, 2018, the Company completed the March Offering, wherein a total of 2,857,144 shares of the Company’s common stock were issued at a purchase price of $1.75 per share, for a total purchase price of $5.0 million, with each investor also receiving a warrant to purchase up to a number of shares of common stock equal to the number of shares of common stock purchased by such investor in the offering at an exercise price of $2.17 per share. The March Offering raised net cash proceeds of approximately $4.5 million (after deducting the placement agent fee and expenses of the March Offering). The Company is using the net cash proceeds from the March Offering for working capital purposes, to fund required dividend payments, payment of principal and interest payments under short-term borrowing obligations, and payment of interest (but not principal) under long-term borrowing obligations. The Company engaged Chardan Capital Markets, LLC (“Chardan”) as placement agent for the March Offering pursuant to an engagement letter agreement. The Company agreed to pay Chardan a cash placement fee equal to 8.0% of the gross proceeds of the March Offering, and issued to Chardan a warrant to purchase shares of common stock equal to 3.0% of the number of shares sold in the March Offering (the “Chardan Warrant”). The Chardan Warrant has an exercise price of $2.365 per share, a term of 5.5 years from the closing date of the March Offering, and otherwise has identical terms to the warrants issued to the investors in the March Offering. Pursuant to the purchase agreement entered in connection with the March Offering (the “March Purchase Agreement”), the Company used its best efforts to cause the conversion of all shares of the Company’s Series B 10% Convertible Preferred Stock (the “Series B Preferred Stock”) into shares of common stock pursuant to the terms of the Company’s Certificate of Designation (the “Certificate of Designation”) with respect to the Series B Preferred Stock. In connection therewith, the Company entered into letter agreements with each of William W. Smith, Jr. (“Smith”) and Andrew Arno (“Arno”), whereby each of Smith and Arno agreed to take certain action to convert the shares of Series B Preferred Stock held by them pursuant to terms outlined in the March Purchase Agreement, and further agreed that the shares of common stock issued upon such conversion shall not be subject to resale registration rights. Each of Smith and Arno completed the conversion of their shares of Series B Preferred Stock in accordance with such letter agreements. The Company prepared and filed a registration statement with the SEC for the purpose of registering the resale of shares of common stock issued in the March Offering, and such registration statement became effective within the time period agreed by the parties to the March Offering. May 2018 Offering On May 3, 2018, the Company completed the May Offering, wherein a total of 3,170,000 shares of the Company’s common stock were issued at a purchase price of $2.21 per share, for a total purchase price of approximately $7.0 million, with each investor also receiving a warrant to purchase up to a number of shares of common stock equal to the number of shares of common stock purchased by such investor in the Offering at an exercise price of $2.11 per share. The May Offering raised net cash proceeds of approximately $6.3 million (after deducting the placement agent fee and expenses). The Company is using the net cash proceeds from the May Offering for working capital purposes, and to fund required dividend payments, payment of principal and interest payments under short-term borrowing obligations, and payment of interest (but not principal) under long-term borrowing obligations. The Company engaged Chardan as placement agent for the May Offering pursuant to an engagement letter agreement. The Company agreed to pay Chardan a cash placement fee equal to 7.0% of the gross proceeds of the May Offering. The Company also engaged Roth Capital Partners, LLC (“Roth”) as its financial advisor for the May Offering. The Company agreed to pay Roth a cash fee equal to 2.0% of the gross proceeds of the May Offering. The Company prepared and filed a registration statement with the SEC for the purpose of registering the resale of shares of common stock issued in the May Offering, and such registration statement became effective within the time period agreed by the parties to the May Offering. The Company has outstanding warrants issued pursuant to an agreement entered into on September 6, 2016 with Unterberg Koller Capital Fund L.P. (the “Unterberg Warrant Agreement”). The March Offering caused a Triggering Event as defined in the Unterberg Warrant Agreement, and the warrants were repriced from an exercise price of $2.14 to $2.07. The Triggering Event charges of $11 thousand were recorded to Stockholders’ Equity during the first quarter of 2018. In connection with the Company’s September 2017 offering of Series B Preferred Stock (the “Series B Transaction”) to certain investors (the “Series B Stockholders”), the Company entered into a Registration Rights Agreement with investors (the “Series B Registration Rights Agreement”) under which the Company agreed to prepare and file a registration statement with the SEC within 30 days after closing of the Series B Transaction for the purpose of registering the resale of shares of common stock issuable upon conversion of the Series B Preferred Stock (the “Conversion Shares”). The Company agreed to use its reasonable best efforts to cause such resale registration statement to be declared effective by the SEC within 90 days after the closing of the Series B Transaction (120 days in the event the registration statement is reviewed by the SEC) and agreed to pay liquidated damages to the Series B Stockholders if such resale registration statement were not to become effective within the applicable time period. The Conversion Shares were included in the registration statement filed in connection with the March Offering, and such registration statement became effective on April 19, 2018, which was later than the deadline specified in the Series B Registration Rights Agreement, resulting in liquidated damage payments of $48 thousand to Series B Stockholders. Certain Series B Stockholders, including without limitation, Smith and Arno, waived their rights to receive such liquidated damage payments.

Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes We account for income taxes as required by FASB ASC Topic No. 740, Income Taxes The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax liabilities against gross deferred tax assets); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies; and (4) future taxable income exclusive of reversing temporary differences and carryforwards. In assessing whether a valuation allowance is required, significant weight is to be given to evidence that can be objectively verified. A significant factor in the Company’s assessment is that the Company has been in a five-year historical cumulative loss as of the end of fiscal 2017. These facts, combined with uncertain near-term market and economic conditions, reduced the Company’s ability to rely on projections of future taxable income in assessing the realizability of its deferred tax assets. After a review of the four sources of taxable income as of December 31, 2017 (as described above), and after consideration of the Company’s continuing cumulative loss position as of December 31, 2017, the Company will continue to reserve its U.S.-based deferred tax amounts, which total $52.9 million, as of September 30, 2018. The Company is subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. Federal income tax returns of the Company are currently subject to IRS examination for the 2013 – 2017 tax years. State income tax returns are subject to examination for a period of three to four years after filing. The outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs. We may from time to time be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to our consolidated financial results. It is the Company’s policy to classify any interest and/or penalties in the consolidated financial statements as a component of income tax expense.

Basis of Presentation	Basis of Presentation The accompanying interim consolidated balance sheet as of September 30, 2018, and the related consolidated statements of operations and comprehensive loss and cash flows for each of the three and nine months ended September 30, 2018 and 2017, are unaudited. The unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been omitted. In the opinion of management, the accompanying unaudited consolidated financial statements for the periods presented reflect all adjustments which are normal and recurring, and necessary to fairly state the financial position, results of operations, and cash flows of the Company. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 filed with the SEC on March 30, 2018 and amended April 17, 2018. Intercompany balances and transactions have been eliminated in consolidation. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2018.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606)
Revenue Recognition	Revenue Recognition We currently report our net revenues under two operating groups: Wireless and Graphics. Generally, we recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed and determinable, and collectability is probable. We recognize revenues from sales of our software (or software that we are licensed to distribute) to our customers or end users as completed products are shipped and title passes, or from royalties generated as authorized customers duplicate our software, if the other requirements are met. If the requirements are not met as of the date of shipment, revenue is not recognized until these elements are known or resolved. For Wireless, we recognize revenue using several different methods beyond the method previously mentioned. First, we provide some customers a subscription service arrangement (the “Platform”). This Platform is then deployed to their customers, the end users, either directly by our customer or by the end user initiating a download of the Platform. Our service arrangement can include the use of the software application, hosting services, and maintenance and support services for the Platform. This type of arrangement is recognized on a point in time basis separately for each billing cycle (i.e. monthly or quarterly) based on the individual metrics within that period, and results in either a fixed fee per end user or a revenue sharing arrangement based on amounts received by our customers. Second, we provide other related services to some customers specific to hosting services, and maintenance and support services. These arrangements are recognized on a per period basis (i.e. typically monthly or quarterly) based on the individual arrangements agreed upon with our customers. These arrangements typically include a fixed fee for services offered within the period. Sometimes these types of services include up-front, non-refundable set-up fees. Revenue is recognized for these fees over the term of the agreement. Third, we provide a limited custom software development services under a fixed fee arrangement. This revenue is recognized based on agreed-upon deliverables and milestones – when value is provided to the customer a portion of the revenue is recognized. There are no significant judgments required for this revenue. However, we do make some estimates to accrue revenue through the fiscal quarter ends. For Graphics, we review available retail channel information and make a determination of a return provision for sales made to distributors and retailers based on current channel inventory levels and historical return patterns. Certain sales to distributors or retailers are made on a consignment basis. Revenues for consignment sales are not recognized until sell-through to the final customer is established. Certain revenues are booked net of revenue sharing payments. Sales directly to end users are recognized upon shipment. End users have a thirty-day return period, but such returns are reasonably estimable and have historically been minimal. We also provide technical support to our customers. Such costs have historically been insignificant. Deferred revenue represents amounts billed to customers for which revenue has not been recognized. Deferred revenue primarily consists of the unearned portion of monthly, quarterly and annually billed service fees and prepayments made by customers for a future period. Revenues on a disaggregated basis are as follows (in thousands): For the Three Months Ended September 30, For the Nine Months Ended September 30, 2018 2017 2018 2017 (unaudited) (unaudited) Wireless: Software $ 48 $ 193 $ 311 $ 264 Platform 5,908 3,603 15,780 10,858 Services 339 593 1,406 1,954 Contract (12 ) 301 108 602 Total wireless $ 6,283 $ 4,690 $ 17,605 $ 13,678 Graphics: Software 242 1,114 1,328 3,564 Total revenues $ 6,525 $ 5,804 $ 18,933 $ 17,242
Fair Value Measurements	Fair Value Measurements The Company measures and discloses fair value measurements as required by FASB Accounting Standards Codification (“ASC”) Topic No. 820, Fair Value Measurements and Disclosures Fair value is an exit price, representing the amount that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: • Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets • Level 2 - Include other inputs that are directly or indirectly observable in the marketplace • Level 3 - Unobservable inputs which are supported by little or no market activity The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. As required by FASB ASC Topic No. 820, we measure our cash and cash equivalents at fair value. Our cash equivalents are classified within Level 1 by using quoted market prices utilizing market observable inputs. As required by FASB ASC Topic No. 820, we measure our warrant liability at fair value. Our warrant liability is classified within Level 3 as some of the inputs to our valuation model are either not observable quoted prices or are not derived principally from, or corroborated by, observable market data by correlation or other means. As required by FASB ASC Topic No. 820, we utilize quoted market prices to estimate the fair value of our fixed rate debt, when available. If quoted market prices are not available, we calculate the fair value of our fixed rate debt based on a currently available market rate, assuming the loans are outstanding through maturity and considering the collateral securing the loans. In determining the current market rate for fixed rate debt, a market spread is added to the quoted yields on federal government treasury securities with similar terms to the debt.
Going Concern Evaluation	Going Concern Evaluation In connection with preparing consolidated financial statements for the three and nine months ended September 30, 2018, management evaluated whether there were conditions and events that, when considered in the aggregate, raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the historical operating loss and negative cash flow from operating activities trends. Ordinarily, conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern relate to the entity’s ability to meet its obligations as they become due. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following: • In May 2017, the Company raised $2.2 million of new capital in a private placement offering of its common stock. • In September 2017, the Company closed on a $5.5 million preferred stock transaction which converted $2.8 million of long and short-term debt, and raised $2.7 million of new capital. • On March 5, 2018, the Company raised $5.0 million of new capital in a private placement offering of its common stock. • On May 3, 2018, the Company raised $7.0 million of new capital in a private placement offering of its common stock. In addition to the recent capital raised, management also believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months from the issuance date. The Company will take the following actions, if it starts to trend unfavorably against its internal profitability and cash flow projections, in order to mitigate conditions or events that would raise substantial doubt about its ability to continue as a going concern: • Raise additional funds through short-term loans. • Implement additional restructuring and cost reductions. • Raise additional capital through a private placement. • Secure a commercial bank line of credit. • Dispose of one or more product lines. • Sell or license intellectual property.

Going Concern Evaluation [Line Items]
Substantial doubt about going concern, management's evaluation					In connection with preparing consolidated financial statements for the three and nine months ended September 30, 2018, management evaluated whether there were conditions and events that, when considered in the aggregate, raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the historical operating loss and negative cash flow from operating activities trends. Ordinarily, conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern relate to the entity’s ability to meet its obligations as they become due. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following:  In May 2017, the Company raised $2.2 million of new capital in a private placement offering of its common stock.  In September 2017, the Company closed on a $5.5 million preferred stock transaction which converted $2.8 million of long and short-term debt, and raised $2.7 million of new capital.  On March 5, 2018, the Company raised $5.0 million of new capital in a private placement offering of its common stock.  On May 3, 2018, the Company raised $7.0 million of new capital in a private placement offering of its common stock. In addition to the recent capital raised, management also believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months from the issuance date.
