Organization, Consolidation and Presentation of Financial Statements [Abstract]
Substantial Doubt about Going Concern [Text Block]	Note 2 – Liquidity and Going Concern These consolidated financial statements have been prepared in conformity with GAAP, which contemplates continuation of the Company as a going concern. As reflected in the accompanying financial statements, for the year ended March 31, 2018, the Company incurred a net loss of $4,322,311 and a loss of $298,030 for the nine months ended December 31, 2018. As discussed in Note 15 to the Notes to the Condensed Consolidated Financial Statements, the Company has recorded estimated damages to date of $5,216,647, including interest and additional fees, as a result of the jury verdict associated with the Aeroflex litigation. The Company has filed for an appeal. The jury found no misappropriation of Aeroflex trade secrets but it did rule that the Company tortiously interfered with a prospective business opportunity and awarded damages. The jury ruled that Tel tortiously interfered with Aeroflex’s non-disclosure agreements with two former Aeroflex employees. The jury also found that the former Aeroflex employees breached their non-disclosure agreements with Aeroflex. The Court conducted further hearings on the Company’s post-trial motions which sought to reduce the damages award of $2.8 million, as well as the punitive damages claim. The Court denied the Company’s motions and awarded Aeroflex an additional $2.1 million of punitive damages. The Company has filed motions in January 2018 for the Court to reconsider the amount of damages on the grounds that they are duplicative and not legally supportable. The Court heard these motions and such motions were denied. The Company has filed for the appeal. The Company has posted a $2,000,000 bond for the appeal. This $2 million bond amount will remain in place during the appeal process (See Note 15). The Company believes it has solid grounds to appeal this verdict. The appeal process is expected to take several years to complete. However, the Company cannot predict the timing or the outcome of the appeal. The Company believes it has sufficient financing in place to fund its plans for the next twelve months due in part to recent large orders it has received that should return the Company to profitability. The Company’s line of credit agreement expires on May 31, 2019. On October 5, 2018, the Company entered into a definitive subscription agreement with an accredited investor, pursuant to which the investor purchased an aggregate of 166,667 shares of the Company’s Series B Preferred Stock (the “Series B Preferred”) for $1 million. The Company intends to use such proceeds for working capital purposes. We have no other firm commitments from any party to provide additional working capital and there is no assurance that any funding will be available as required, or if available, that its terms will be favorable or acceptable to the Company. The pending judgment raises substantial doubt about the Company’s ability to continue as a going concern within one year of the date that the financial statements are issued. The financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. The accompanying financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.
