Liquidity and Going Concern [Line Items]
Substantial Doubt about Going Concern [Text Block]	Note 2 – Liquidity and Going Concern A fundamental principle of the preparation of financial statements in accordance with GAAP is the assumption that an entity will continue in existence as a going concern, which contemplates continuity of operations and the realization of assets and settlement of liabilities occurring in the ordinary course of business. This principle is applicable to all entities except for entities in liquidation or entities for which liquidation appears imminent. In accordance with this requirement, the Company has prepared its accompanying Consolidated Financial Statements assuming the Company will continue as a going concern. Due to the onset of the COVID-19 pandemic in 2020, the Company experienced a reduction in sales orders from customers. As a result, the Company incurred a net loss of $2.8 million in the nine months ended September 30, 2021 and had a working capital deficiency of $8.6 million as of September 30, 2021. In addition, the Company has past due principal and interest payments on our outstanding 8¼% Limited convertible senior subordinated notes due 2012 (the “Notes”) and 9½% Subordinated debentures due 2012 (the “Debentures”). 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, including the impact of the current economic environment, the spread of major epidemics (including coronavirus) and other related uncertainties such as government-imposed travel restrictions, interruptions to supply chains, extended shut down of businesses and the impact of inflation. 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. If we are unable to (i) obtain additional liquidity for working capital, (ii) make the required minimum funding contributions to the defined benefit pension plan, (iii) make the required principal and interest payments on the Notes and the Debentures and/or (iv) repay our obligations under our Loan Agreement (hereinafter defined) with Unilumin (assigned from MidCap Business Credit LLC (“MidCap”) in July 2021), there would be a significant adverse impact on our financial position and operating results. The Company continually evaluates the need and availability of long-term capital in order to meet its cash requirements and fund potential new opportunities. Due to the above, there is substantial doubt as to whether we will have adequate liquidity, including access to the debt and equity capital markets, to operate our business over the next 12 months from the date of issuance of this Form 10-Q.
