Notes to Financial Statements
Significant Accounting Policies [Text Block]	4. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES a) Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Future events and their effects cannot be determined with certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from those estimates, and any such differences may b) Business Combinations Assets and liabilities acquired in a business combination are accounted for at fair value. The Company records the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values at the acquisition dates. The excess, if any, of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. If the fair value of the assets and liabilities acquired exceed the fair value of the purchase consideration, negative goodwill is recognized in the statement of operations. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not may Goodwill resulting from a business combination is not may not not, not The Company performs its review for impairment during the third one August 31, 2021, c) Asset Acquisition Acquisitions of the assets of a business are accounted for at cost based on their allocated fair value. The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values at the acquisition dates. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not may not d) Cash and Cash Equivalents Cash and cash equivalents include bank deposits and short-term, highly liquid investments. Investments acquired with maturity dates of three e) Restricted Cash The Company’s restricted cash – current was $0.1 million and $6.4 million at November 30, 2021 2020, $0.1 November 30, 2021 November 2019 $6.4 November 30, 2020 November 30, 2021 November 30, 2020, f) Allowance for Doubtful Accounts Receivable The Company provides an allowance for its accounts receivable for estimated losses that may may November 30, 2021 2020 g) Inventories Inventories are principally comprised of raw materials and finished goods and are valued at the lower of cost or net realizable value with cost being determined on the first first h) Property and Equipment Property and equipment are recorded at cost and reflected net of accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, primarily three seven three seven i) Patent Rights The perpetual, irrevocable, exclusive and non-exclusive license to use technology with respect to the cost of patent rights is capitalized and amortized over the estimated useful life, currently estimated to be 15 to 17 years. j) Impairment of Long-Lived Assets Long-lived assets to be held and used are analyzed for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not not November 30, 2021 2020, k) Convertible Notes Payable When the Company has determined that the embedded conversion options should not 470 20, l) Fair Value of Financial Instruments The Company determines fair value based on its accounting policy for fair value measurement (i.e. exit price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date). See note 4 not 1 m) Revenue Recognition Product Sales The Company generates revenue through the wholesale distribution of its products and accessories to dealers/distributors, large end-users such as security companies and law enforcement agencies, and through an e-commerce portal to consumers. Revenue is recognized upon transfer of control of goods to the customer, which generally occurs when title to goods is passed and risk of loss transfers to the customer. Depending on the contract terms, transfer of control is upon shipment of goods to or upon the customer’s pick-up of the goods. Payment terms to customers other than e-commerce customers are generally 30 60 first one three 3 first second third second third The Company also has a 60 60 60 November 30, 2021 60 November 30, 2020 The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. Shipping and handling costs associated with the distribution of finished products to customers, are recorded in operating expenses in the accompanying Consolidated Statements of Operations and Comprehensive Loss and are recognized when the product is shipped to the customer. Included as cost of goods sold are costs associated with the production and procurement of products, such as labor and overhead, inbound freight costs, manufacturing depreciation, purchasing and receiving costs, and inspection costs. Contract Liabilities Current deferred revenue primarily relates to unfulfilled e-commerce orders for the years ended November 30, 2021 2020. n) Marketing and Advertising Marketing and advertising related costs are expensed as incurred and are included in operating expenses in the accompanying Consolidated Statements of Operations and Comprehensive Loss and were $2.7 million and $1.0 million during the years ended November 30, 2021 2020, o) Research and Development Research and development (“R&D”) costs are expensed as incurred and are included in operating expenses in the accompanying Consolidated Statements of Operations and Comprehensive Loss. R&D costs were $0.3 million and $0.04 million during the years ended November 30, 2021 2020, p) Incomes Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized to the extent the Company believes that these assets are more likely than not The Company records uncertain tax positions on the basis of a two 1 not 2 not 50 not may November 30, 2021 2020, not If incurred, the Company recognizes interest and penalties related to income taxes on the income tax expense line in the accompanying Consolidated Statement of Operations and Comprehensive Loss. As of November 30, 2021 2020, The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal and state jurisdictions, where applicable. There are currently no November 30, 2018, not On March 27, 2020, $2 not q) Loss Per Share Basic loss per share is computed by dividing net loss, reduced by dividends, by the weighted-average number of common shares outstanding for the year. Diluted loss per share is computed by dividing net loss, reduced by dividends, by the weighted-average number of common shares outstanding plus common stock equivalents (if dilutive) related to stock options, restricted stock units, and warrants for each year and the conversion feature of convertible notes payable. r) Stock-Based Compensation The Company accounts for all stock-based payment awards granted to employees and non-employees as stock-based compensation expense at their grant date fair value. The Company’s stock-based payments include stock options, restricted stock units, and incentive warrants. The measurement date for employee awards is the date of grant, and stock-based compensation costs are recognized as expense over the employees’ requisite service period, on a straight-line basis. The measurement date for non-employee awards is the date of grant and stock-based compensation costs for non-employees are recognized as expense over the vesting period on a straight-line basis. Stock-based compensation is classified in the accompanying Statements of Operations and Comprehensive Loss based on the function to which the related services are provided, which is included in operating expenses in the accompanying Consolidated Statements of Operations and Comprehensive Loss. Forfeitures are accounted for as they occur. The fair value of each stock option grant is estimated on the date of grant by using either the Black-Scholes, Binomial Lattice, or the quoted stock price on the date of grant, unless the awards are subject to market conditions in which case we use the Monte Carlo simulation model. Due to the Company’s limited history, the expected term of the Company’s stock options granted to employees has been determined utilizing the method as prescribed by the SEC’s Staff Accounting Bulletin, Topic 14. not s) Foreign Currency Transactions Foreign currency transactions are transactions denominated in a currency other than a subsidiary’s functional currency. A change in the exchange rates between a subsidiary’s functional currency and the currency in which a transaction is denominated increases or decreases the expected amount of functional currency cash flows upon settlement of the transaction. That increase or decrease in expected functional currency cash flows is recorded as other income (expense), in the accompanying Consolidated Statements of Operations and Comprehensive Loss. t) Foreign Currency Translation The Company maintains its books and records in US Dollars, which is its functional and reporting currency. Assets and liabilities of the Company’s international subsidiaries in which the local currency is the functional currency are translated into US Dollars at period-end exchange rates. Income and expenses are translated into US Dollars at the average exchange rates during the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets as a component of accumulated other comprehensive income (loss). u) Other Comprehensive Income (Loss) Other comprehensive income (loss) consists of foreign currency translation adjustments. v) Fair Value Measurement The Company follows a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to settle a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three ● Level 1 ● Level 2 1 ● Level 3 w) Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In August 2018, 2018 13, 820 2018 13” 820. 2018 13 2018 13 first 2021. 2018 13 not Accounting Pronouncements Issued but Not In 2019, 2019 12, 740 not first 2022. 2019 12 not In January 2017, 2017 04, 350 2017 04” 2 2017 04 first 2024. 2017 04 not In 2016, 2016 13, 326 2016 13” 2016 13 December 2023

Revenue from Contract with Customer [Policy Text Block]	m) Revenue Recognition Product Sales The Company generates revenue through the wholesale distribution of its products and accessories to dealers/distributors, large end-users such as security companies and law enforcement agencies, and through an e-commerce portal to consumers. Revenue is recognized upon transfer of control of goods to the customer, which generally occurs when title to goods is passed and risk of loss transfers to the customer.

Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse.

Earnings Per Share, Policy [Policy Text Block]	q) Loss Per Share Basic loss per share is computed by dividing net loss, reduced by dividends, by the weighted-average number of common shares outstanding for the year. Diluted loss per share is computed by dividing net loss, reduced by dividends, by the weighted-average number of common shares outstanding plus common stock equivalents (if dilutive) related to stock options, restricted stock units, and warrants for each year and the conversion feature of convertible notes payable.
Share-based Payment Arrangement [Policy Text Block]	r) Stock-Based Compensation The Company accounts for all stock-based payment awards granted to employees and non-employees as stock-based compensation expense at their grant date fair value. The Company’s stock-based payments include stock options, restricted stock units, and incentive warrants. The measurement date for employee awards is the date of grant, and stock-based compensation costs are recognized as expense over the employees’ requisite service period, on a straight-line basis. The measurement date for non-employee awards is the date of grant and stock-based compensation costs for non-employees are recognized as expense over the vesting period on a straight-line basis. Stock-based compensation is classified in the accompanying Statements of Operations and Comprehensive Loss based on the function to which the related services are provided, which is included in operating expenses in the accompanying Consolidated Statements of Operations and Comprehensive Loss. Forfeitures are accounted for as they occur. The fair value of each stock option grant is estimated on the date of grant by using either the Black-Scholes, Binomial Lattice, or the quoted stock price on the date of grant, unless the awards are subject to market conditions in which case we use the Monte Carlo simulation model. Due to the Company’s limited history, the expected term of the Company’s stock options granted to employees has been determined utilizing the method as prescribed by the SEC’s Staff Accounting Bulletin, Topic 14. not
Foreign Currency Transactions and Translations Policy [Policy Text Block]	s) Foreign Currency Transactions Foreign currency transactions are transactions denominated in a currency other than a subsidiary’s functional currency. A change in the exchange rates between a subsidiary’s functional currency and the currency in which a transaction is denominated increases or decreases the expected amount of functional currency cash flows upon settlement of the transaction. That increase or decrease in expected functional currency cash flows is recorded as other income (expense), in the accompanying Consolidated Statements of Operations and Comprehensive Loss. t) Foreign Currency Translation The Company maintains its books and records in US Dollars, which is its functional and reporting currency. Assets and liabilities of the Company’s international subsidiaries in which the local currency is the functional currency are translated into US Dollars at period-end exchange rates. Income and expenses are translated into US Dollars at the average exchange rates during the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets as a component of accumulated other comprehensive income (loss).
Comprehensive Income, Policy [Policy Text Block]	u) Other Comprehensive Income (Loss) Other comprehensive income (loss) consists of foreign currency translation adjustments.
Fair Value Measurement, Policy [Policy Text Block]	v) Fair Value Measurement The Company follows a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to settle a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three ● Level 1 ● Level 2 1 ● Level 3
