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 Condensed Consolidated Financial Statements assuming the Company will continue as a going concern. The Company has incurred recurring operating losses and continues to have a working capital deficiency including being in default on several debt obligations. The Company recorded a loss of $1.3 million in the three months ended March 31, 2024, and had a working capital deficiency of $15.2 million as of March 31, 2024. As of December 31, 2023, the Company had a working capital deficiency of $13.9 million. The Company is dependent on future operating performance to be able 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), increases in interest rates 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 our outstanding 8¼% Limited convertible senior subordinated notes due 2012 (the “Notes”) and 9½% Subordinated debentures due 2012 (the “Debentures”), (iv) repay our obligations under our Loan Agreement (hereinafter defined) with Unilumin and/or (v) repay our obligations under our loan agreements with Carlisle, 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 continue as a going concern over the next 12 months from the date of issuance of this Form 10-Q.
