Liquidation Basis of Accounting [Text Block]	2. Liquidity The Company has incurred recurring losses and has a working capital deficiency. The Company incurred a net loss of $1.4 million in 2019 and had a working capital deficiency of $3.1 million as of December 31, 2019. The Company is dependent on future operating performance in order to generate sufficient cash flows in order to continue to run its businesses. Future operating performance is dependent on general economic conditions, as well as financial, competitive and other factors beyond our control. In order to more effectively manage its cash resources, the Company had, from time to time, increased the timetable of its payment of some of its payables, which delayed certain product deliveries from our vendors, which in turn delayed certain deliveries to our customers. In March and April 2019, the Company received aggregate proceeds of $8.0 million from (i) a rights offering to current shareholders under which the shareholders could purchase shares of our Common Stock at an exercise price of $1.00 per share, resulting in gross proceeds of $2.5 million (the “Rights Offering”) and (ii) the exercise of the $5.5 million warrant (the “Unilumin Warrant”) issued to Unilumin North America Inc. (“Unilumin”) Of these proceeds, a portion was used to satisfy outstanding obligations including certain long-term debt, certain payables, certain accrued liabilities and pension obligations. On September 16, 2019, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with MidCap Business Credit LLC (“MidCap”) as lender. The Loan Agreement allows the Company to borrow up to an aggregate of $4.0 million on a revolving credit loan based on accounts receivable, inventory and equipment for general working capital purposes. A stockholder of the Company has committed to providing additional capital up to $2.0 million through December 31, 2020, to the extent necessary to fund operations. Management believes that its current cash resources and cash provided by operations will be sufficient to fund its anticipated current and near-term cash requirements within one year from the date of issuance of this Form 10-K. The Company continually evaluates the need and availability of long-term capital in order to meet its cash requirements and fund potential new opportunities.
