Reclassification, Comparability Adjustment [Policy Text Block]

Reclassification of Comparative Amounts

The Company previously offset certain Trade Payables with Advances to Suppliers associated with one vendor. In accordance with U.S. GAAP, the Company determined there is no intent to settle the Trade Payables on a net basis. The error is a reclassification which results in an increase of Trade Payables and Advances to Suppliers. Items previously reported have been reclassified to conform to U.S. GAAP and the reclassification did not have any impact on the consolidated statements of operations, consolidated statements of comprehensive loss, or consolidated statement of stockholders' equity.

The following table summarizes the impact of the reclassification adjustments on the Company's Form 10-K previously filed on March 28, 2022 as well as the unaudited condensed consolidated balance sheets for the affected Quarterly Periods in 2022:

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions made in the accompanying consolidated financial statements include, but are not limited to, the implicit interest rate used to record lease revenue, allowance for doubtful accounts, inventory valuation, stock-based compensation, warranty accrual, the valuation and measurement of deferred tax assets and liabilities, accrued severance pay, useful lives of property and equipment, earn-out liability, useful lives of intangible assets, impairment of long-lived assets and valuation of acquired intangible assets. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist primarily of funds invested in readily available checking and savings accounts, investments in money market funds and short-term time deposits.

Risk and Uncertainties [Policy Text Block]

Risks and Uncertainties

While the impact of COVID-19 on our Company has largely subsided, we continue to closely monitor all COVID-19 developments including its impact on our customers, employees, suppliers, vendors, business partners, and distribution channels. In addition, the global economy, including the financial and credit markets, has recently experienced extreme volatility and disruptions, including increases to inflation rates, rising interest rates, foreign currency impacts, and declines in economic growth. All these factors point to uncertainty about economic stability, and the severity and duration of these conditions on our Company cannot be predicted.

Besides COVID-19, the Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, rapid technological change, continued acceptance of the Company’s products, competition from substitute products and larger companies, protection of proprietary technology, strategic relationships and dependence on key individuals. If the Company fails to adhere to the FDA’s Quality System Regulation, or regulations in countries other than the United States, the FDA or other regulators may withdraw its market clearances or take other action. The Company relies on suppliers to manufacture some of the components used in its products. The Company’s suppliers may encounter supply interruptions or problems during manufacturing due to a variety of reasons, including failure to comply with applicable regulations, including the FDA’s Quality System Regulation, making errors in manufacturing or losing access to critical services and components, any of which could delay or impede the Company’s ability to meet demand for its products.

The Company has borrowings with interest rates that are subject to fluctuations as charged by the lender. The Company does not use derivative financial instruments to mitigate the exposure to interest rate risk. The Company’s objective is to have sufficient liquidity to meet its liabilities when due. The Company monitors its cash balances and cash used in operating activities to meet its requirements. As of December 31, 2022 and 2021, the most significant financial liabilities are trade payables, accrued expenses and other current liabilities and long-term debt.

Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]

Allowance for Doubtful Accounts

Trade accounts receivable do not bear interest and are typically not collateralized. The Company performs ongoing credit evaluations of its customers’ financial condition and maintains an allowance for doubtful accounts. Uncollectible accounts are charged to expense when deemed uncollectible, and accounts receivable are presented net of an allowance for doubtful accounts. Accounts receivable are deemed past due in accordance with the contractual terms of the agreement. Actual losses may differ from the Company’s estimates and could be material to the Company's consolidated financial position, results of operations and cash flows. The allowance for doubtful accounts was $13,619 and $11,997 as of December 31, 2022 and 2021, respectively.

Receivable [Policy Text Block]

Long-term Receivables

Long-term receivables relate to the Company’s subscription revenue or contracts which stipulate payment terms which exceed one year. They are comprised of the unpaid principal balance, plus accrued interest, net of the allowance for credit losses. These receivables have been discounted based on the implicit interest rate in the subscription lease which range between 8% to 10% for the year ended December 31, 2022 and 8% to 9% for the year ended December 31, 2021. Unearned interest revenue represents the interest only portion of the respective subscription payments and will be recognized in income over the respective payment term as it is earned.

Deferred revenues represent payments received prior to the income being earned. Once the equipment has been delivered or the services have been rendered, these amounts are recognized in income.

Lessee, Leases [Policy Text Block]

Leases

The Company determines if an agreement is, or contains, a lease at inception. An agreement is, or contains, a lease if the contact conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company leases assets including land and buildings, vehicles, and equipment. For leases with a term of 12 months or less or of low value, the payments are expensed as incurred.

The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

An operating lease is a lease in which a lessor transfers the use of an asset to a lessee for a period of time but does not effectively transfer control of the underlying asset. For lessees, a lease is a finance lease if the lessee effectively obtains control of the underlying asset, by meeting any of the following five criteria:

i.

The lease transfers ownership of the underlying asset to the lessee by the end of the lease term.

ii.

The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise.

iii.

The lease term is for a major part (generally 75%) of the remaining economic life of the underlying asset.

iv.

The sum of the lease payments and the present value of any residual value guaranteed by the lessee amounts to or exceeds substantially all (generally 90%) of the fair value of the underlying asset.

v.

The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term.

For a finance lease, the right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. The estimated useful lives of right-of-use assets are determined on the same basis as those of property, plant and equipment. For an operating lease, amortization of the right-of-use asset is calculated as the difference between the straight-line rent expense and the interest expense on the lease liability for a given period. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company uses its incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate. The Company has determined that there are no variable payments, residual value guarantees, lease renewal options or early termination options that are reasonably certain to be exercised, and therefore have been excluded these from initial measurement.

The lease liabilities are subsequently measured at amortized cost using the effective interest method. They are remeasured when there is a change in future lease payments arising from a change in the lease term, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension or termination option.

All of our leases for which we are the lessee are operating leases and are included within operating lease right-of-use assets, net, operating lease liabilities, and long-term operating lease liabilities in our Consolidated Balance Sheets.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of Long-Lived Assets

The Company accounts for the impairment of long-lived assets in accordance with FASB, ASC 360-10, “Accounting for the Impairment of Long-Lived Assets”. This standard requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the assets’ carrying amounts may not be recoverable. For assets that are to be held and used, impairment is assessed when the estimated undiscounted cash flows associated with the asset or group of assets is less than their carrying values. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is recorded as the difference between the carrying value and fair value. Fair values are determined based on quoted market values, discounted cash flows or internal and external appraisals, as applicable. Assets to be disposed of are carried at the lower of carrying value and estimated net realizable value. During the years ended December 31, 2022 and 2021, there was no impairment of long-lived assets.

Derivatives, Policy [Policy Text Block]

Derivatives

The Company reviews the terms of convertible notes, equity instruments and other financing arrangements to determine whether there are embedded derivative instruments, including embedded conversion options that are required to be bifurcated and accounted for separately as a derivative financial instrument. Derivative financial instruments are initially measured at their fair value. Derivative financial instruments that are accounted for as liabilities, are initially recorded at fair value and then re-valued at each reporting date, with changes in the fair value recognized in the consolidated statements of operations.

Cost of Goods and Service [Policy Text Block]

Cost of Goods

For subscription sales (qualifying as sales-type lease arrangements) and product sales, the costs are recognized upon shipment to the customer or distributor.

Research and Development Expense, Policy [Policy Text Block]

Research and Development

Research and development costs are charged to operations as incurred. Major components of research and development expenses consist of personnel costs, including salaries and benefits, hardware and software research and development costs, and clinical studies.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company follows the deferred income taxes method of accounting for income taxes. Under this method, deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying values of accounts and their respective income tax basis. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years during which the temporary differences are expected to be realized or settled. The effect on deferred income tax assets and liabilities of a change in tax rates is included in income in the period that includes the enactment date.

The Company establishes valuation allowances when necessary to reduce deferred tax assets to the amounts that are more likely than not to be realized. The Company evaluates tax positions taken or expected to be taken in the course of preparing tax returns to determine whether the tax positions have met a “more likely-than-not” threshold of being sustained by the applicable tax authority. Tax benefits related to tax positions not deemed to meet the “more likely-than-not” threshold are not permitted to be recognized in the consolidated financial statements.

Share-Based Payment Arrangement [Policy Text Block]

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718, “Compensation – Stock Compensation” (“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in the Company’s consolidated statements of operations.

The fair value of stock options (“options”) on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award. The Company recognizes compensation expenses for the value of its awards granted based on the straight-line method over the requisite service period of each of the awards. The Company has made a policy choice to account for forfeitures when they occur.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Standards

In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832). The authoritative guidance intended to provide consistent and transparent disclosures around government assistance by requiring disclosures of the type of government assistance, our accounting for the government assistance and the effect on our financial statements. This guidance was effective for the Company for the year ended December 31, 2021. See Note 14 for more details regarding government assistance.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02 “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to put most leases on the balance sheet but recognize expense on the income statement in a manner similar to current accounting.

On January 1, 2022, the Company adopted the standard and all related amendments, using the optional transition method (modified retrospective approach) applied to leases at the adoption date. Under the modified retrospective approach, comparative periods have not been restated and continue to be reported under the accounting standards in effect for those periods.

The Company elected the optional package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs. The Company also elected the practical expedient to not separate lease components from non-lease components for real estate leases.

As a result of the adoption of ASU 2016-02, the Company recorded right-of-use assets (“ROU”) of $5,862 and corresponding lease liabilities of $6,028 with no adjustment made to opening accumulated deficit.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. Upon adoption of ASU 2016-02, ROU assets were adjusted for deferred rent and prepaids as of January 1, 2022. Lease expense is recognized on a straight-line basis over the expected lease term. The Company’s incremental borrowing rate is used in determining the present value of future payments at the commencement date of the lease, or for the adoption of ASU 2016-02, at January 1, 2022. Balances related to operating leases are included in ROU assets and current or noncurrent lease liabilities on the consolidated balance sheet.

All real estate leases are recorded on the balance sheet. Equipment and other non-real estate leases with an initial term of twelve months or less are not recorded on the balance sheet. Lease agreements for some locations provide for rent escalations and renewal options. Many leases include one or more options to renew the lease at the end of the initial term. The Company considered renewals in its ROU assets and operating lease liabilities. Certain real estate leases require payment for taxes, insurance and maintenance which are considered non-lease components. The company excluded the non-lease components for all real estate leases and included the non-lease components for all other leases (e.g., cars and equipment). The non-lease components were not separated for certain assets, as there may be no practical way to split the components in certain leases (e.g., cars) and are not material to the company.

The Company determines if an arrangement is a lease at inception. The Company must consider whether the contract conveys the right to control the use of an identified asset. Certain arrangements require significant judgment to determine if an asset is specified in the contract and if the Company directs how and for what purpose the asset is used during the term of the contract.

In October 2021, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update ("ASU") No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an entity (acquirer) to recognize and measure contract assets and liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. This update is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. The amendments should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The adoption of the guidance did not have a material impact on the Company's consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260): Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40)”, which clarifies and reduces diversity in an issuer’s accounting for a modification or an exchange of a freestanding equity-classified written call option that remains equity being classified after modification or exchange as (1) an adjustment to equity and, if so, the related earnings per share (EPS) effects, if any, or (2) an expense and, if so, the manner and pattern of recognition. This was effective for fiscal years beginning after December 15, 2021, and interim periods within those years. The adoption of the guidance did not have a material impact on the Company's consolidated financial statements.

In March 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-04 - Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASC Topic 848). This authoritative guidance provides optional relief for companies preparing for the discontinuation of interest rates such as LIBOR, which was phased out at the end of calendar 2021, and applies to lease contracts, hedging instruments, held-to-maturity debt securities and debt arrangements that have LIBOR as the benchmark rate. This guidance can be applied for a limited time, as of the beginning of the interim period that includes March 12, 2020 or any date thereafter, through December 31, 2022. The guidance may no longer be applied after December 31, 2022. In January 2021, the FASB issued authoritative guidance that makes amendments to the new rules on accounting for reference rate reform. The amendments clarify that all derivative instruments affected by the changes to interest rates used for discounting, margining or contract price alignment, regardless of whether they reference LIBOR, or another rate expected to be discontinued as a result of reference rate reform, an entity may apply certain practical expedients in ASC Topic 848. The adoption of the guidance did not have a material impact on the Company’s consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12 – Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, an authoritative guidance that simplifies the accounting for income taxes by removing certain exceptions and making simplifications in other areas. It is effective from the first quarter of fiscal year 2022, with early adoption permitted in any interim period. The amendments have differing adoption methods including retrospectively, prospectively and/or modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption, depending on the specific change. The adoption of the guidance did not have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Standards Not Yet Adopted

In August 2020, the FASB issued ASU No. 2020-06 (“ASU 2020-06”): Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 reduces the number of accounting models for convertible debt instruments by eliminating the cash conversion and beneficial conversion models. The diluted net income per share calculation for convertible instruments will require us to use the if-converted method. For contracts in an entity’s own equity, the type of contracts primarily affected by this update are freestanding and embedded features that are accounted for as derivatives under the current guidance due to a failure to meet the settlement conditions of the derivative scope exception. This update simplifies the related settlement assessment by removing the requirements to (i) consider whether the contract would be settled in registered shares, (ii) consider whether collateral is required to be posted, and (iii) assess shareholder rights. ASU 2020-06 is effective for the Company on January 1, 2024, with early adoption permitted. ASU No. 2020-06 can be adopted on either a fully retrospective or modified retrospective basis. The Company is currently assessing the impact of applying this guidance as well as when to adopt this guidance.

In February 2020, the FASB issued authoritative guidance (ASU 2020-02 – Financial Instruments – Credit Losses (Topic 326) and Leases (Topic 842)) that amends and clarifies Topic 326 and Topic 842. For Topic 326, the codification was updated to include the SEC staff interpretations associated with registrants engaged in lending activities. ASC Topic 326 is effective for annual periods beginning after January 1, 2023, including interim periods within those fiscal years. The Company is currently assessing the impact of applying this guidance.
