Substantial Doubt about Going Concern [Text Block]	( 2 The Company incurred net losses of $1.3 $102,000 first 2018 2017, $26.8 June 24, 2017. The Company used cash flow in operations totaling $1.1 $589,000 first 2018 2017, The Company has experienced delays in the development of features, receipt of orders, and shipments for the new Advanced Signal Generator (“ASG”). These delays have contributed, in part to a decrease in working capital. The new ASG product has shipped to several customers, but potential delays in the development of features, longer than anticipated sales cycles, or uncertainty as to the Company’s ability to efficiently manufacture the ASG, could significantly contribute to additional future losses and decreases in working capital. To help fund operations, the Company relies on advances under the line of credit with Bridge Bank which expires on May 6, 2019. June 24, 2017, $582,000. These matters raise substantial doubt as to the Company’s ability to continue as a going concern. To address these matters, the Company’s management has taken several actions to provide additional liquidity and reduce costs and expenses going forward. These actions are described in the following paragraphs. ● On April 27, 2017, $1,500,000, April 28, 2017. two June 24, 2017, not August 2, 2017, August) No 6%.

In the first 2018, $160,000. Management will continue to review all aspects of the business in an effort to improve cash flow and reduce costs and expenses, while continuing to invest, to the extent possible, in new product development for future revenue streams. Management will also continue to seek additional working capital through debt, equity financing or possible product line sales, however there are no The Company’s historical operating results and forecasting uncertainties indicate that substantial doubt exists related to the Company’s ability to continue as a going concern. Forecasting uncertainties exist with respect to the ASG product line due to the potential longer than anticipated sales cycles as well as with potential delays in the refinement of certain features, and/or the Company’s ability to efficiently manufacture it in a timely manner. The accompanying Consolidated Financial Statements have been prepared assuming that the Company will continue as a going concern and do not

The Company limits the amount of revenue recognition for delivered elements to the amount that is not a. It is commensurate with either of the following: 1. 2. b.

Notes to Financial Statements
Fair Value Disclosures [Text Block]	( 8 ) Fair Value Pursuant to the accounting guidance for fair value measurement and its subsequent updates, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. The accounting guidance establishes a hierarchy for inputs used in measuring fair value that minimizes the use of unobservable inputs by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data. Unobservable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. The fair value hierarchy is broken down into the three • Level 1 1 • Level 2 2 • Level 3 no Fair value measurements discussed herein are based upon certain market assumptions and pertinent information available to management as of and during the three June 24, 2017. June 24, 2017, 2 Derivatives not Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract.
