Organization Consolidation And Presentation Of Financial Statements [Abstract]
Going Concern Evaluation	4. Going Concern Evaluation In connection with preparing consolidated financial statements for the three and nine months ended September 30, 2017, management evaluated whether there were conditions and events, considered in the aggregate, that 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 following: • Operating losses for ten consecutive quarters. • Negative cash flow from operating activities for six consecutive quarters. • Depressed stock price resulting in being non-compliant with NASDAQ listing rules to maintain a stock price of $1.00/share. • Stockholders’ equity being less than $2.5 million at March 31, 2017 and June 30, 2017 resulting in being non-compliant with NASDAQ listing rules. 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: • The Company raised $4 million of debt financing during the year ended December 31, 2016. • The Company has raised funds from short-term loans from insiders. • As a result of the Company’s restructurings that were implemented during the three months ended December 31, 2016, and again during the six months ended June 30, 2017, the Company’s cost structure is now in line with its future revenue projections. See Footnote 11 below for additional details regarding restructurings. • On September 29, 2017, the Company completed a $5.5 million preferred stock transaction, which converted $2.8 million of long term and short-term debt (face value) into equity and raised $2.7 million of new equity capital. Management believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months. The Company will take the following actions, if it starts to trend unfavorably to 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.

Earnings Per Share [Abstract]
Net Loss Per Share	13. Net Loss Per Share The Company calculates earnings per share (“EPS”) as required by FASB ASC Topic No. 260, Earnings Per Share On August 15, 2016, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of Delaware for the purpose of effecting a reverse stock split (the “Reverse Split”) of the outstanding shares of the Company’s common stock at a ratio of one (1) share for every four (4) shares outstanding, so that every four (4) outstanding shares of common stock before the Reverse Split represents one (1) share of common stock after the Reverse Split. Proportionate adjustments were made to: (i) the aggregate number of shares of Common Stock available for equity-based awards to be granted in the future under our 2015 Omnibus Equity Incentive Plan; (ii) the number of shares that would be owned upon vesting of restricted stock awards and stock options which are outstanding under our 2015 Omnibus Equity Incentive Plan and 2005 Stock Option Plan, and the exercise price of any outstanding stock options, and (iii) the number of shares of Common Stock available for purchase under our Preferred Shares Rights Agreement, dated October 16, 2015, between us and Computershare Trust Company, N.A., as rights agent. We have a total of 100,000,000 authorized shares of common stock, which remained unchanged by the reverse stock split. The Reverse Split was approved by the Company’s stockholders at the special meeting held on August 15, 2016 and was effective on August 17, 2016. The Company adjusted shareholders' equity to reflect the reverse stock split by reclassifying an amount equal to the par value of the additional shares arising from the split from common stock to the Additional Paid-in Capital during the third quarter of fiscal 2016, resulting in no net impact to shareholders' equity on our consolidated balance sheets. Fractional shares were rounded down to the nearest whole share. Stockholders received cash in lieu of such fractional shares. All information presented herein has been retrospectively adjusted to reflect the reverse stock split as if it took place as of the earliest period presented. On September 29, 2017, the Company filed with the Secretary of State of the State of Delaware a Certificate of Designation of Preferences, Rights and Limitations of Series B Preferred Stock of the Company (the “Certificate of Designation”), designating a total of 5,500 shares of Series B Preferred Stock. Under the Certificate of Designation, the shares of Series B Preferred Stock have a stated value of $1,000 per share and are optionally convertible, subject to certain limitations set forth in the Certificate of Designation, into shares of the Company’s Common Stock at a conversion price of $1.14 per share, subject to adjustment in the event of a stock split, stock dividend, combination, reclassification or other recapitalization affecting the Common Stock. The holders of Series B Preferred Stock are entitled to receive cumulative dividends out of funds legally available thereof at payable (i) when and as declared by the Board of Directors, in quarterly installments on March 1, June 1, September 1 and December 1, and (ii) upon conversion into Common Stock with respect the Series B Preferred Stock being converted. In the event that the trading price of the Company’s Common Stock for 20 consecutive trading days (as determined in the Certificate of Designation) exceeds 400% of the then effective Conversion Price of the Series B Preferred Stock (initially set at $1.14), the Company may force conversion of the Series B Preferred Stock into shares of Common Stock or elect to redeem the Series B Preferred Stock for cash. Until the date that stockholder approval is obtained, the Certificate of Designation limits the number of shares of Common Stock that are issuable to any holder upon conversion of such holder’s Series B Preferred Stock, such that such issuances would not cause such holder to own in excess of 19.99% of the Company’s issued and outstanding Common Stock. In addition, a holder’s shares of Series B Preferred Stock shall not be converted if, after giving effect to the conversion, such holder and its affiliated persons would own beneficially more than 9.99% of the Company’s Common Stock, subject to adjustment solely at the holder’s discretion upon 61 days’ prior notice to the Company.

Fair Value Disclosures [Abstract]
Fair Value Measurements	15. Fair Value Measurements The Company measures and discloses fair value measurements as required by FASB 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. The Company early adopted ASU 2017-11 and changed its method of accounting for warrants during the nine months ended September 30, 2017 on a full retrospective basis. (See Note 19).

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 relation to certain transactions.

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.

Equity Transactions Preferred Stock Offering On September 29, 2017, the Company entered into a Securities Purchase Agreement with several investors for the issuance and sale (the “Offering”) of 5,500 shares of the Company’s newly designated Series B 10% Convertible Preferred Stock (the “Series B Preferred Stock”) at a stated value of $1,000 per share, for a total purchase price of $5.5 million. The Series B Preferred Stock is convertible into the Company’s Common Stock at a conversion price of $1.14 per share, which was the closing bid price of the Common Stock on September 28, 2017, or approximately 4,824,562 shares of Common Stock in the aggregate. The holders of Preferred Stock are entitled to receive cumulative dividends a rate of ten percent (10%) per annum, In the event that the trading price of the Company’s Common Stock for 20 consecutive trading days (as determined in the Certificate of Designation) exceeds 400% of the then effective Conversion Price of the Series B Preferred Stock (initially set at $1.14), the Company may force conversion of the Series B Preferred Stock into shares of Common Stock or elect to redeem the Series B Preferred Stock for cash. In addition, Series B Preferred Stock In the Offering, the Company raised gross cash proceeds of $2.7 million, and exchanged outstanding indebtedness with a principal amount of $2.8 million owed to Smith (both long and short-term debt) and $0.1 million owed to Arno. The Offering raised net cash proceeds of $2.5 million (after deducting the placement agent fee and expenses of the Offering). The Company intends to use the net cash proceeds from the Offering for working capital purposes. In connection with the Offering, the Company granted customary registration rights to investors with respect to the resale of shares of Common Stock issuable upon conversion of the Series B Convertible Preferred Stock. Common Stock Offering On May 16, 2017, the Company entered into subscription agreements with several investors for the issuance and sale of an aggregate of 2,077,000 shares of its common stock, in a registered direct offering at a purchase price of $1.05 per share. The Shares were offered by the Company pursuant to a shelf registration statement on Form S-3 (File No. 333-215786), which was declared effective on February 10, 2017 by the Securities and Exchange Commission (the “SEC”). Also, on May 16, 2017, the Company entered into subscription agreements with four accredited investors in a private placement pursuant to which the Company issued and sold to the Investors an aggregate of 85,000 shares of its unregistered common stock at a price per share of $1.10. The Company engaged Sutter Securities Incorporated and Chardan Capital Markets, LLC as co-placement agents in connection with the registered direct offering pursuant to engagement letter agreements with each firm. The Company agreed to pay the placement agents a cash placement fee and issued to the placement agents warrants to purchase shares of Common Stock equal to 5% of the number of shares sold through each of them, without duplication, at an exercise price per share equal to $1.21 (Sutter) and $1.155 (Chardan). The warrants have a term of five years and will be exercisable beginning on November 18, 2017. The transactions closed on May 17, 2017 and the Company realized gross proceeds of $2.3 million before deducting transaction fees and other expenses. Offering costs related to the transaction totaled $0.2 million, comprised of $0.1 million of transaction fees and $0.1 million of legal and other expenses, resulting in net proceeds of $2.1 million. Warrants On September 2, 2016, we entered into a Note and Warrant Purchase Agreement with Unterberg Koller Capital Fund L.P. and William W. and Dieva L. Smith (collectively, the “Investors”), pursuant to which the Company issued five-year warrants (the “Warrants”) to purchase an aggregate of 1,700,000 shares of the Company’s common stock at an Exercise Price of $2.74 per share, which expire five years from the date of issuance. The Company completed the transaction contemplated by the Note and Warrant Purchase Agreement and issued the Warrants on September 6, 2016. The Warrants contain provisions that if the Company sells or issues shares of Common Stock (as defined in Warrants) with an exercise price per share less than the Exercise Price of $2.74, the Exercise Price shall be adjusted according to the terms set forth within the Warrants (“Triggering Event”). On May 16, 2017, the Company engaged Sutter Securities Incorporated (“Sutter”) and Chardan Capital Markets, LLC (“Chardan”) as co-placement agents in connection with a registered direct offering. The Company agreed to pay the placement agents a cash placement fee and issued to the placement agents warrants to purchase shares of Common Stock equal to 5% of the number of shares sold through each of them, without duplication, at an exercise price per share equal to $1.21 (Sutter) and $1.155 (Chardan). The warrants issued to Sutter and Chardan have a term of five years and will be exercisable beginning on November 18, 2017. Since the issuance of the Warrants on September 6, 2016, there have been five Triggering Events, which caused the Warrants to be repriced from the original Exercise Price of $2.74: Common Stock offerings in May 2017 for $1.10 and 1.05, the issuance of warrants to Sutter and Chardan with exercise prices of $1.21 and $1.155, respectively, all resulting in a charge of $3,000, and the Series B Preferred Stock issuance with a conversion price of $1.14 in September 2017, resulting in a charge of $41,000. The Triggering Event charges were recorded to Stockholders’ Equity in the applicable period. Upon application of the Triggering Events above, the Unterberg Koller Capital Fund L.P. Adjusted Exercise Price is $2.14 and the Smith Adjusted Exercise Price is $2.38, which is also the agreed upon floor for the Smith Warrants. The Company early adopted ASU 2017-11 and changed its method of accounting for certain warrants that were initially recorded as liabilities during the nine months ended September 30, 2017 on a full retrospective basis. Since the warrants were issued in conjunction with the Related – party notes payable and Notes payable (the “Notes Payable”) issuance, the Company also revalued the amount of debt discount related to the valuation of the warrants, which impacted the net carrying value of Notes Payable. Accordingly, the Company reclassified the Warrant liability to Additional paid in capital of $1.8 million and $1.2 million and the change in valuation of the amount of debt discount from the Notes payable to Additional paid-in capital of $0.7 million and $0.7 million on the consolidated balance sheets for the three months ended September 30, 2016 and the year ended December 31, 2016, respectively. In addition, due to the retrospective adoption, for the year ended December 31, 2016, the Company credited the Change in fair value of warrant liability on its consolidated statements of operations by $0.9 million with the same offset to Accumulated deficit on the consolidated balance sheets. The following table provides a reconciliation of Warrant liability, Additional paid-in capital, Accumulated deficit and Change in fair value of warrant liability on the consolidated balance sheets for the three months ended September 30, 2016 and the year ended December 31, 2016 (in thousands): Consolidated Balance Sheet Related-party notes payable Notes payable Warrant liability Additional paid-in capital Accumulated deficit Balance, September 30, 2016 (Prior to adoption of ASU 2017-11) $ 883 $ 883 $ 1,761 $ 227,565 $ (222,185 ) Change in valuation of notes payable 359 359 — (718 ) — Reclassification of warrant liability — — (1,761 ) 1,761 — Change in fair value of warrant liability — — — 335 (335 ) Change in interest (expense) income, net — — — (17 ) 17 Balance, September 30, 2016 (After adoption of ASU 2017-11) $ 1,242 $ 1,242 $ — $ 228,926 $ (222,503 ) Consolidated Balance Sheet Related-party notes payable Notes payable Warrant liability Additional paid-in capital Accumulated deficit Balance, December 31, 2016 (Prior to adoption of ASU 2017-11) $ 967 $ 967 $ 1,210 $ 227,889 $ (225,397 ) Change in valuation of notes payable 328 328 — (656 ) — Reclassification of warrant liability — — (1,210 ) 1,210 — Change in fair value of warrant liability — — — 910 (910 ) Change in interest (expense) income, net — — — (79 ) 79 Balance, December 31, 2016 (After adoption of ASU 2017-11) $ 1,295 $ 1,295 $ — $ 229,274 $ (226,228 ) The adoption of ASU 2017-11 increased the Loss before provision for income taxes and Net loss by $0.3 million for the three months and nine months ended September 30, 2016, and increased the Net loss per share by $0.03 and $0.02 for the same periods, respectively. During the nine months ended September 30, 2017, there was no impact on the Loss before provision for income taxes, Net loss and Net loss per share due to the adoption of ASU 2017-11. The Company’s consolidated statement of cash flows for the nine months ended September 30, 2016 was also impacted by the adoption of ASU 2017-11,

Income Tax Disclosure [Abstract]
Income Taxes	20. 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 year 2016. 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, 2016 (as described above), and after consideration of the Company’s continuing cumulative loss position as of December 31, 2016, the Company will continue to reserve its US-based deferred tax amounts, which total $76.3 million, as of September 30, 2017. 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 subject to IRS examination for the 2012 – 2016 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.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim consolidated balance sheet and statement of stockholders’ equity as of September 30, 2017, and the related consolidated statements of operations and comprehensive loss and cash flows for the three and nine months ended September 30, 2017 and 2016, 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, necessary to fairly state the financial position, results of operations, and cash flows. 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, 2016 filed with the SEC. Intercompany balances and transactions have been eliminated in consolidation. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2017.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In July 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-11, Earnings Per Share (Topic 260) Distinguishing Liabilities from Equity (Topic 480) Derivatives and Hedging (Topic 815) (“ASU 2017-11”) The Company has elected to early adopt ASU 2017-11 during the three months ended September 30, 2017 by applying ASU 2017-11 retrospectively to outstanding financial instruments with a down round feature for each prior reporting period presented which includes the quarter ended September 30, 2016 in accordance with the guidance on accounting changes in paragraphs 250-10-45-5 through 45-10. (See Note 19). 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)
Going Concern Evaluation	Going Concern Evaluation In connection with preparing consolidated financial statements for the three and nine months ended September 30, 2017, management evaluated whether there were conditions and events, considered in the aggregate, that 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 following: • Operating losses for ten consecutive quarters. • Negative cash flow from operating activities for six consecutive quarters. • Depressed stock price resulting in being non-compliant with NASDAQ listing rules to maintain a stock price of $1.00/share. • Stockholders’ equity being less than $2.5 million at March 31, 2017 and June 30, 2017 resulting in being non-compliant with NASDAQ listing rules. 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: • The Company raised $4 million of debt financing during the year ended December 31, 2016. • The Company has raised funds from short-term loans from insiders. • As a result of the Company’s restructurings that were implemented during the three months ended December 31, 2016, and again during the six months ended June 30, 2017, the Company’s cost structure is now in line with its future revenue projections. See Footnote 11 below for additional details regarding restructurings. • On September 29, 2017, the Company completed a $5.5 million preferred stock transaction, which converted $2.8 million of long term and short-term debt (face value) into equity and raised $2.7 million of new equity capital. Management believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months. The Company will take the following actions, if it starts to trend unfavorably to 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.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents are primarily held in two financial institutions and are uninsured except for the minimum Federal Deposit Insurance Corporation coverage and have original maturity dates of three months or less. As of September 30, 2017 and December 31, 2016, bank balances totaling approximately $3.7 million and $2.1 million, respectively, were uninsured.
Accounts Receivable	Accounts Receivable The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company maintains reserves for estimated credit losses and those losses have been within management’s estimates. Allowances for product returns are included in other adjustments to accounts receivable on the consolidated balance sheets. Product returns are estimated based on historical experience and management estimations. The Company is utilizing the accounts receivable balances to secure the related party short-term notes payable.
Impairment or Disposal of Long Lived Assets	Impairment or Disposal of Long Lived Assets Long-lived assets to be held are reviewed for events or changes in circumstances, which indicate that their carrying value may not be recoverable. They are tested for recoverability using undiscounted cash flows to determine whether or not impairment to such value has occurred as required by FASB ASC Topic No. 360, Property, Plant, and Equipment
Equipment and Improvements	Equipment and Improvements Equipment and improvements are stated at cost. Depreciation is computed using the straight-line method based on the estimated useful lives of the assets, generally ranging from three to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the asset or the lease term.
Goodwill	Goodwill In accordance with FASB ASC Topic No. 350, Intangibles-Goodwill and Other
Net Loss Per Share	Net Loss Per Share The Company calculates earnings per share (“EPS”) as required by FASB ASC Topic No. 260, Earnings Per Share On August 15, 2016, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of Delaware for the purpose of effecting a reverse stock split (the “Reverse Split”) of the outstanding shares of the Company’s common stock at a ratio of one (1) share for every four (4) shares outstanding, so that every four (4) outstanding shares of common stock before the Reverse Split represents one (1) share of common stock after the Reverse Split. Proportionate adjustments were made to: (i) the aggregate number of shares of Common Stock available for equity-based awards to be granted in the future under our 2015 Omnibus Equity Incentive Plan; (ii) the number of shares that would be owned upon vesting of restricted stock awards and stock options which are outstanding under our 2015 Omnibus Equity Incentive Plan and 2005 Stock Option Plan, and the exercise price of any outstanding stock options, and (iii) the number of shares of Common Stock available for purchase under our Preferred Shares Rights Agreement, dated October 16, 2015, between us and Computershare Trust Company, N.A., as rights agent. We have a total of 100,000,000 authorized shares of common stock, which remained unchanged by the reverse stock split. The Reverse Split was approved by the Company’s stockholders at the special meeting held on August 15, 2016 and was effective on August 17, 2016. The Company adjusted shareholders' equity to reflect the reverse stock split by reclassifying an amount equal to the par value of the additional shares arising from the split from common stock to the Additional Paid-in Capital during the third quarter of fiscal 2016, resulting in no net impact to shareholders' equity on our consolidated balance sheets. Fractional shares were rounded down to the nearest whole share. Stockholders received cash in lieu of such fractional shares. All information presented herein has been retrospectively adjusted to reflect the reverse stock split as if it took place as of the earliest period presented. On September 29, 2017, the Company filed with the Secretary of State of the State of Delaware a Certificate of Designation of Preferences, Rights and Limitations of Series B Preferred Stock of the Company (the “Certificate of Designation”), designating a total of 5,500 shares of Series B Preferred Stock. Under the Certificate of Designation, the shares of Series B Preferred Stock have a stated value of $1,000 per share and are optionally convertible, subject to certain limitations set forth in the Certificate of Designation, into shares of the Company’s Common Stock at a conversion price of $1.14 per share, subject to adjustment in the event of a stock split, stock dividend, combination, reclassification or other recapitalization affecting the Common Stock. The holders of Series B Preferred Stock are entitled to receive cumulative dividends out of funds legally available thereof at payable (i) when and as declared by the Board of Directors, in quarterly installments on March 1, June 1, September 1 and December 1, and (ii) upon conversion into Common Stock with respect the Series B Preferred Stock being converted. In the event that the trading price of the Company’s Common Stock for 20 consecutive trading days (as determined in the Certificate of Designation) exceeds 400% of the then effective Conversion Price of the Series B Preferred Stock (initially set at $1.14), the Company may force conversion of the Series B Preferred Stock into shares of Common Stock or elect to redeem the Series B Preferred Stock for cash. Until the date that stockholder approval is obtained, the Certificate of Designation limits the number of shares of Common Stock that are issuable to any holder upon conversion of such holder’s Series B Preferred Stock, such that such issuances would not cause such holder to own in excess of 19.99% of the Company’s issued and outstanding Common Stock. In addition, a holder’s shares of Series B Preferred Stock shall not be converted if, after giving effect to the conversion, such holder and its affiliated persons would own beneficially more than 9.99% of the Company’s Common Stock, subject to adjustment solely at the holder’s discretion upon 61 days’ prior notice to the Company.

Stock-Based Compensation	Stock Compensation The Company accounts for all stock-based payment awards made to employees and directors based on their fair values, which is recognized as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation
Fair Value Measurements	Fair Value Measurements The Company measures and discloses fair value measurements as required by FASB 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. The Company early adopted ASU 2017-11 and changed its method of accounting for warrants during the nine months ended September 30, 2017 on a full retrospective basis. (See Note 19).

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, 2017, management evaluated whether there were conditions and events, considered in the aggregate, that 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 following:  Operating losses for ten consecutive quarters.  Negative cash flow from operating activities for six consecutive quarters.  Depressed stock price resulting in being non-compliant with NASDAQ listing rules to maintain a stock price of $1.00/share.  Stockholders’ equity being less than $2.5 million at March 31, 2017 and June 30, 2017 resulting in being non-compliant with NASDAQ listing rules. 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:  The Company raised $4 million of debt financing during the year ended December 31, 2016.  The Company has raised funds from short-term loans from insiders.  As a result of the Company’s restructurings that were implemented during the three months ended December 31, 2016, and again during the six months ended June 30, 2017, the Company’s cost structure is now in line with its future revenue projections. See Footnote 11 below for additional details regarding restructurings.  On September 29, 2017, the Company completed a $5.5 million preferred stock transaction, which converted $2.8 million of long term and short-term debt (face value) into equity and raised $2.7 million of new equity capital. Management believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months.
