Document Type 10-Q/A  
Amendment Flag true  
Amendment Description On May 3, 2024, the Company was made aware that its long standing auditors, BF Borgers CPA PC, had been denied the privilege of appearing or practicing before the Securities and Exchange Commission (the “SEC”) as an accountant. In view of the nature of the actions taken by the SEC in relation to the Company’s former auditor, the SEC required the Company to have its new auditors review 2 years of its quarterly financial statements along with the reaudit of 2 years of annual financial statements. This has resulted in a deficiency in the Company’s filings entirely due to circumstances beyond the control of the Company. The Company appointed a new registered public accounting firm: Fruci & Associates II PLLC, Certified Public Accountants based in Spokane, Washington (“Fruci & Associates”) to replace BF Borgers.This present Quarterly Report filed on Form 10-Q/A (the “Report”) includes modifications resulting from the completion of the audit carried out by Fruci & Associates on the Company’s 2023 Annual Report filed on Form 10-K/A on April 28, 2025 as well as the review of the present restated Report and is duly filed in replacement of the original July 15, 2024 filing.  The principal change to the 10-Q are as follows:   Two important adjustments were made to the Company’s financial statements: 1) the Company’s technology, considered in filings since September 2021 to be an indefinite intangible asset was reevaluated and is now considered to have an estimated useful life equivalent to the period of its underlining patent protection, appropriate amortization being charged to the value of the asset accordingly. This has resulted in an adjustment of $495,592 to the asset value as of March 31, 2024. This has resulted in a charge of $187,227 against the value of the asset as amortization; and 2) the balance sheet was readjusted to include $308,365 of retained earnings.   On the Company’s condensed balance sheet, the Company will now report any “Commitments and Contingencies” as a separate line item.   Generally, the Report has been made consistent with the Company’s 2023 Annual Report filed on Form 10-K/A on April 28, 2025 and with the introduction of small changes in presentation and with some greater detail to improve disclosure.   Matters relating to projected timing in the Report have been changed from the original disclosure better to reflect the current belief of management regarding such projections. Where necessary or helpful, the circumstances relating to the need for such adjustment are also reported.   A number of other changes were made to punctuation and grammar that do not affect the sense of disclosure, and where dollar figures included cents, these were rounded up to the nearest dollar.
