Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 10 – Income Taxes FASB ASC 740-10, “Accounting for Uncertainty in Income Taxes” (“ASC 740-10”) prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company has analyzed filing positions in all of the federal and state jurisdictions where it is required to file income tax returns, as well as all open tax years in these jurisdictions. The Company does not have any unrecognized tax benefits. The tax effect of temporary differences, primarily net operating loss carryforwards, asset reserves and accrued liabilities, gave rise to the Company’s deferred tax asset. Deferred income taxes are recognized for the tax consequence of such temporary differences at the enacted tax rate expected to be in effect when the differences reverse. The Company had approximately $2.6 million in deferred tax assets at December 31, 2020. Future profitability in this competitive industry depends on continually obtaining and fulfilling new profitable sales agreements and modifying products. The inability to obtain new profitable contracts or the failure of the Company’s engineering development efforts could reduce estimates of future profitability, which could affect the Company’s ability to realize the deferred tax assets. The recognized deferred tax asset is based upon the expected utilization of its benefit from future taxable income. The Company has federal net operating loss (“NOL”) carryforwards of approximately $3.6 million. These carryforward losses are available to offset future taxable income, and begin to expire in the year 2027.
