Foreign Currency Transactions and Translations Policy [Policy Text Block]

The Company's functional currency is the US dollar. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the results of operations as incurred. Foreign currency transaction gains or losses included in net loss were immaterial for the years ended June 30, 2020 and 2019.

The preparation of financial statements in conformity with accounting principles generally affected in the US Generally Accepted Accounting Principles ("US GAAP") requires management to make estimates and assumptions that impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Fair Value of Financial Instruments

The carrying amounts for cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities approximate their fair value because of their short-term maturity. The carrying amount of the accrued post retirement benefits approximates fair value since the Company utilizes approximate current market interest rates to calculate the liability. The Company determined that the carrying amount of the notes payable and lease liabilities approximates fair value since such debt borrowing bears interest at the approximate current market rate. While the Company believes the carrying value of the assets and liabilities are reasonable, considerable judgment is used to develop estimates of fair value; thus the estimates are not necessarily indicative of the amounts that could be realized in a current market exchange.

Shipping and Handling Cost, Policy [Policy Text Block]

Shipping and handling revenues are included in product revenue and the related costs are included in cost of goods sold.

Property, Plant and Equipment, Policy [Policy Text Block]

Property and equipment are recorded at cost. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or lease term. Depreciation on property and equipment is recorded using the straight-line method over the estimated economic useful life of the related assets. Estimated useful lives are generally three years to five years for computer equipment and software, five years to seven years for furniture and fixtures and five years to ten years for production and test equipment. Depreciation and amortization expense for the years ended June 30, 2020 and 2019 was approximately $30,000 and $30,000, respectively.

Property and equipment consist of the following:

	$	97,214		$	67,896

Intangible Assets

ntangible assets deemed to have indefinite lives (including trademark and trade names) are not amortized but, instead, are subject to an annual impairment assessment. Additionally, if events or conditions were to indicate the carrying value or a reporting unit may not be recoverable, the Company would evaluate the other intangible assets for impairment at that time.

Long-lived assets including intangible assets deemed to have finite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment indicators include, among other conditions, cash flow deficits, historic or anticipated declines in revenue or operating profit or material adverse changes in the business climate that indicate that the carrying amount of an asset may be impaired. When impairment indicators are present, the recoverability of the asset is measured by comparing the carrying value of the asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the projected undiscounted cash flows from the asset are less than the carrying value of the asset the asset is considered to be impaired. The impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

The Company tests indefinite-life intangible assets for possible impairment on an annual basis at June 30, and at any other time events occur or circumstances indicate that the carrying amount of intangible assets may be impaired. Due to the current low market capitalization of the Company's common stock, the Company performed an interim impairment test on its intangible asset as of December 31, 2019. The outcome of this impairment test resulted in non-cash charge for the full impairment of the indefinite-lived intangible assets (trade mark and trade names) of $605,000, which was recorded in the consolidated financial statements for fiscal year 2020. No impairments were recorded in year ended

Net Income (loss) Per Share

Earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the year. All outstanding stock options are considered potential common stock. All outstanding convertible preferred stock are considered common stock at the beginning of the period or at the time of issuance, if later, pursuant to the if-converted method. The dilutive effect, if any, of stock options is calculated using the treasury stock method. As of June 30, 2020 and 2019, the average market prices for the years then ended are less than the exercise price of all the outstanding stock options and, therefore, the inclusion of the stock options would be anti-dilutive. In addition, since the effect of common stock equivalents is anti-dilutive with respect to losses, the convertible preferred stock has also been excluded from the Company’s computation of loss per common for the years ended June 30, 2020 and 2019. Therefore, basic and diluted loss per common share for the years ended June 30, 2020 and 2019 are the same.

Lessee, Leases [Policy Text Block]

The Company determines if an arrangement is a lease at the inception of a contract. Operating lease right-of-use ("ROU") assets are included in right-of-use assets on the consolidated balance sheets. The current and long-term components of operating lease liabilities are included in the current portion of operating lease liabilities and operating lease liabilities, net of current portion, respectively on the consolidated balance sheets.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. Certain leases may include options to extend or terminate the lease. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

New Accounting Pronouncements

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally affected in the US Generally Accepted Accounting Principles ("US GAAP") requires management to make estimates and assumptions that impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

For the purposes of reporting cash flows, the Company considers all cash accounts, which are not subject to withdrawal restrictions or penalties, and highly liquid investments with original maturities of 90 days or less to be cash and cash equivalents. From time to time cash balances exceed federal insurance limits.

Restricted Cash

As of June 30, 2020 and June 30, 2019 restricted cash included $255,281 and $253,135 respectively, which was pursuant to the requirements in the TD Bank Loan entered into June 2018 (see Note 6).

Foreign Currency Translation

The Company's functional currency is the US dollar. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the results of operations as incurred. Foreign currency transaction gains or losses included in net loss were immaterial for the years ended June 30, 2020 and 2019.

Accounts Receivable

Accounts receivable are recorded at net realizable value. The Company performs ongoing credit evaluations of customers’ financial condition and does not require collateral for accounts receivable arising in the normal course of business. The Company maintains allowances for potential credit losses based on the Company’s historical trends, specific customer issues and current economic trends. Accounts are written off against the allowance when they are determined to be uncollectible based on management’s assessment of individual accounts. The Company recorded an allowance for doubtful accounts of approximately $123,000 and $111,000 as of June 30, 2020 and 2019.

Inventories

Inventories include freight-in materials, labor and overhead costs, and are stated at the lower of cost (first-in, first-out) or net realizable value. The Company writes down its inventories as it becomes aware of any situation whereas the carrying amount exceeds the estimated realizable value based on assumptions about future demands and market conditions.

Property and Equipment

Property and equipment are recorded at cost. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or lease term. Depreciation on property and equipment is recorded using the straight-line method over the estimated economic useful life of the related assets. Estimated useful lives are generally three years to five years for computer equipment and software, five years to seven years for furniture and fixtures and five years to ten years for production and test equipment. Depreciation and amortization expense for the years ended June 30, 2020 and 2019 was approximately $30,000 and $30,000, respectively.

Property and equipment consist of the following:



	June 30,

Intangible Assets and Long-Lived Assets

Intangible assets deemed to have indefinite lives (including trademark and trade names) are not amortized but, instead, are subject to an annual impairment assessment. Additionally, if events or conditions were to indicate the carrying value or a reporting unit may not be recoverable, the Company would evaluate the other intangible assets for impairment at that time.

Long-lived assets including intangible assets deemed to have finite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment indicators include, among other conditions, cash flow deficits, historic or anticipated declines in revenue or operating profit or material adverse changes in the business climate that indicate that the carrying amount of an asset may be impaired. When impairment indicators are present, the recoverability of the asset is measured by comparing the carrying value of the asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the projected undiscounted cash flows from the asset are less than the carrying value of the asset the asset is considered to be impaired. The impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

The Company tests indefinite-life intangible assets for possible impairment on an annual basis at June 30, and at any other time events occur or circumstances indicate that the carrying amount of intangible assets may be impaired. Due to the current low market capitalization of the Company's common stock, the Company performed an interim impairment test on its intangible asset as of December 31, 2019. The outcome of this impairment test resulted in non-cash charge for the full impairment of the indefinite-lived intangible assets (trade mark and trade names) of $605,000, which was recorded in the consolidated financial statements for fiscal year 2020. No impairments were recorded in year ended June 30, 2019 .

Accrued Warranties

The Company provides a limited one-year warranty against manufacturer’s defects on its products sold to customers. The Company’s standard warranties require the Company to repair or replace, at the Company’s discretion, defective parts during such warranty period. The Company accrues for its product warranty liabilities based on estimates of costs to be incurred during the warranty period, based on historical repair information for warranty costs.

PPP Loans

The Company's policy is to account for the PPP loan (See Note 7) as debt. The Company will continue to record the loan as debt until either (1) the loan is partially or entirely forgiven and the Company has been legally released, at which point the amount forgiven will be recorded as income or (2) the Company pays off the loan.

Fair Value of Financial Instruments

The carrying amounts for cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities approximate their fair value because of their short-term maturity. The carrying amount of the accrued post retirement benefits approximates fair value since the Company utilizes approximate current market interest rates to calculate the liability. The Company determined that the carrying amount of the notes payable and lease liabilities approximates fair value since such debt borrowing bears interest at the approximate current market rate. While the Company believes the carrying value of the assets and liabilities are reasonable, considerable judgment is used to develop estimates of fair value; thus the estimates are not necessarily indicative of the amounts that could be realized in a current market exchange.

Revenue Recognition

The Company recognizes revenue when its performance obligations with its customers have been satisfied. At contract inception, the Company determines if the contract is within the scope of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers, and then evaluates the contract using the following five steps: (1) identify the contract with the customer; (2) identify the performance obligations; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only recognizes revenue to the extent that it is probable that a significant revenue reversal will not occur in a future period.

The Company generates product revenue from the sale of medical device products and the sale and installation of the Company's AXIS image management system software. Revenue for service plans relate to the customer care plans for the Company’s equipment and AXIS image management system software.

Revenue is recognized upon transfer of control of the promised goods or services to the customer for an amount that reflects the consideration that the Company expects to be entitled in exchange for those goods or services. The Company’s performance obligations are for product sales, installation of AXIS image management system software and customer care plans. The performance obligations are determined at contract inception based upon promises within the contract that are distinct.

The product sales and installation of AXIS image management system software performance obligations are satisfied at a point in time, which is upon shipment for product sales and upon successful installation for the AXIS image management system. The performance obligation for customer care plans is satisfied over time as the customer receives and consumes the Company’s services.

The Company invoices its customers upon shipment for product sales. For the installation of AXIS image management system software and customer care plans, the Company invoices its customers upon successful installation. Invoice payments are generally due within 30 days of invoice date. The transaction price is determined based on fixed consideration in the Company’s customer contracts and is recorded net of variable consideration. In determining the transaction price, a significant financing component does not exist since the timing from when the Company invoices its customers to when payment is received as it is less than one year.

Revenue for product sales and installation of AXIS image management system software is recognized when delivered or installed. The customer care plan revenues are recognized proportionately over the service period, which is a 12-month period.

The Company has elected the following practical expedients in applying ASC 606:

•

Unsatisfied Performance Obligations - all performance obligations relate to contracts with a duration of less than one year, the Company has elected to apply the optional exemption provided in ASC 606 and therefore, is not required to disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.


•	Contract Costs - all incremental customer contract acquisition costs are expensed as they are incurred as the amortization period of the asset that the Company otherwise would have recognized is one year or less in duration.


•	Significant Financing Component - the Company does not adjust the promised amount of consideration for the effects of a significant financing component as the Company expects, at contract inception, that the period between when the entity transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less.


•	Sales Tax Exclusion from the Transaction Price - the Company excludes from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the Company from the customer.


•	Shipping and Handling Activities - the Company elected to account for shipping and handling activities as a fulfillment cost rather than as a separate performance obligation.


•	Portfolio Approach - the Company applied the Portfolio Approach to contract reviews within its identified revenue streams that have similar characteristics and the Company believes this approach would not differ materially than if applying Topic 606 to each individual contract.

Deferred Revenue

The Company records deferred revenues when cash payments are received or due in advance of its performance. The Company’s deferred revenues relate to payments received for the customer care plans for a 12-month period. The consideration received is recognized monthly over the service period.

Advertising Costs

Advertising costs are charged to operations as incurred. Advertising expense for the years ended June 30, 2020 and 2019 was $17,000 and $33,000, respectively.

Earnings (Loss) Per Share

Earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the year. All outstanding stock options are considered potential common stock. All outstanding convertible preferred stock are considered common stock at the beginning of the period or at the time of issuance, if later, pursuant to the if-converted method. The dilutive effect, if any, of stock options is calculated using the treasury stock method. As of June 30, 2020 and 2019, the average market prices for the years then ended are less than the exercise price of all the outstanding stock options and, therefore, the inclusion of the stock options would be anti-dilutive. In addition, since the effect of common stock equivalents is anti-dilutive with respect to losses, the convertible preferred stock has also been excluded from the Company’s computation of loss per common for the years ended June 30, 2020 and 2019. Therefore, basic and diluted loss per common share for the years ended June 30, 2020 and 2019 are the same.

Income 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 consolidated 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.

The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. As of June 30, 2020 and June 30, 2019, the Company has recorded a full valuation allowance against its deferred tax assets.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statements of operations. As of June 30, 2020 and June 30, 2019, no accrued interest or penalties were required to be included on the related tax liability line in the consolidated balance sheets.

Leases

The Company determines if an arrangement is a lease at the inception of a contract. Operating lease right-of-use ("ROU") assets are included in right-of-use assets on the consolidated balance sheets. The current and long-term components of operating lease liabilities are included in the current portion of operating lease liabilities and operating lease liabilities, net of current portion, respectively on the consolidated balance sheets.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. Certain leases may include options to extend or terminate the lease. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

Reclassifications

Lease deposits of $51,915 in the June 30, 2019 consolidated balance sheet has been reclassed from other current assets to other assets to be in conformity with the current period presentation.

New Accounting Pronouncements

Recently Issued Accounting Standards

The Company considers the applicability and impact of all accounting standards updates ("ASUs"). Management periodically reviews new accounting standards that are issued.

New Accounting Pronouncements Recently Adopted

Effective July 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842), using the cumulative effect adjustment method and elected certain practical expedients allowed under the standard. Upon adoption, the Company recognized ROU assets and a lease liability of $1,138,000 and $1,208,000 respectively. The adoption didn't materially impact the Company's consolidated statements of operations or cash flows. (See Note 15)

In June 2018 the FASB issued ASU 2018-07 Improvements to Nonemployee Share-Based Payment Accounting (Topic 718) that expands the scope to include share-based payment transactions for acquiring goods and services from non-employees. An entity should apply the requirements to nonemployee awards except for certain exemptions specified in the amendment. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that fiscal year. Early adoption is permitted. The adoption of ASU 2018-07 did not have a material impact on the Company's consolidated financial statements.

New Accounting Pronouncements Not yet Adopted

In June 2016 the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which adds a new Topic 326 to the Codification and removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables, and held-to-maturity debt securities. The guidance in ASU 2016-13 is effective for “public business entities,” as defined, that are SEC filers for fiscal years and for interim periods with those fiscal years beginning after December 15, 2022. Early adoption of the guidance is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of this standard is not expected to have a material impact to the Company’s consolidated financial statements.

Advertising Costs, Policy, Capitalized Direct Response Advertising [Policy Text Block]

Advertising costs are charged to operations as incurred. Advertising expense for the years ended June 30, 2020 and 2019 was $17,000 and $33,000, respectively.
