| Significant Accounting Policies [Text Block] | NOTE 1 Basis of Presentation The accompanying condensed consolidated balance sheet as of December 31, 2018, Preparing condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Examples include estimates of loss contingencies, product life cycles and inventory obsolescence, bad debts, sales returns, share-based compensation, forfeiture rates, the potential outcome of future tax consequences of events that have been recognized in our financial statements or tax returns and determining when investment impairments are other-than-temporary.

To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, five five 606, Title and risk of loss generally pass to our customers upon shipment.

At June 30, 2019 $786,000. December 31, 2018, $863,000. Legal and Other Contingencies The outcomes of legal proceedings and claims brought against us are subject to significant uncertainty. An estimated loss from a loss contingency such as a legal proceeding or claim is accrued by a charge to income if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. When legal costs that the entity expects to incur in defending itself in connection with a loss contingency accrual are expected to be material, the loss should factor in all costs and, if the legal costs are reasonably estimable, they should be accrued in accordance with ASC 450, June 30, 2019 $2,000. December 31, 2018, $100,000. Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include cash equivalents, accounts receivable, accounts payable, related party, and other long-term liabilities, approximate their fair values. Accounting for Income Taxes We estimate our tax liabilities based on current tax laws in the statutory jurisdictions in which we operate in accordance with ASC 740, “Income Taxes.” These estimates include judgments about deferred tax assets and liabilities resulting from temporary differences between assets and liabilities recognized for financial reporting purposes and such amounts recognized for tax purposes, as well as about the realization of deferred tax assets. We may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. ASC 740 also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, and income tax disclosures. We maintain a valuation allowance to reduce our deferred tax assets due to the uncertainty surrounding the timing of realizing the benefits of net deferred tax assets in future years. We have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for such a valuation allowance. In the event we were to determine that we would be able to realize all or part of our net deferred tax asset in the future, the valuation allowance would be decreased accordingly. We may periodically undergo examinations by the federal and state regulatory authorities and the Internal Revenue Service. We may be assessed additional taxes and/or penalties contingent on the outcome of these examinations. Our previous examinations have not resulted in any unfavorable or significant assessments. No provision has been made, as the Company has net operating loss carryforwards available to offset taxable income. Leases Effective January 1, 2019, the Company accounts for its leases under ASC 842, Leases . Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases, and are recorded on the consolidated balance sheet as both a right of use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right of use asset result in straight-line rent expense over the lease term. For finance leases, interest on the lease liability and the amortization of the right of use asset results in front-loaded expense over the lease term. Variable lease expenses are recorded when incurred. In calculating the right of use asset and lease liability, the Company has elected to combine lease and non-lease components. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election, and recognizes rent expense on a straight-line basis over the lease term. The Company continues to account for leases in the prior period financial statements under ASC Topic 840. Operating Segments The Company operates in two two |
