SIGNIFICANT ACCOUNTING POLICIES	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES Advertising Expenses - 297,500 178,500 Accounts Receivable, net Cash and Cash Equivalents - 2,892,000 Consolidation Earnings Per Share - Equipment, Furnishings and Leasehold Improvements 3 5 Fair Value of Financial Instruments Fair Value Measurement The carrying amounts of financial instruments reported in the accompanying consolidated financial statements for current assets and current liabilities approximate the fair value because of the immediate or short-term maturities of the financial instruments. The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below: Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities. The fair values of financial assets of the Company were determined using the following categories at February 28, 2023 and February 28, 2022, respectively: Significant accounting policies - fair values of financial assets of the company Level 1 Level 2 Level 3 Total Marketable Securities – February 28, 2023 $ 7,361,000 $ 729,000 $ — $ 8,090,000 Marketable Securities – February 28, 2022 $ 5,716,338 $ 151,652 $ — $ 5,867,990 Marketable Securities include certificates of deposit and US Treasury securities, totaling $ 8,090,000 5,867,990 Income Taxes no Intangible Assets - 17 12 202,681 192,490 11,000 Inventories - Land and Buildings 40 At February 28, 2023 and 2022, the Company had Land, stated at cost of $ 250,000 Long-Lived Assets - No Management Estimates - New Accounting Pronouncements Other than Accounting Standards Update (“ASU”) ASU 2016-13 discussed above, all new accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company. Hence, the adoption of these new accounting pronouncements, once effective, is not expected to have an impact on the Company. Product Warranty Reclassifications Research and Product Development Expenses - During fiscal 2023 and fiscal 2022, the Company spent approximately $ 2,149,000 1,730,000 Revenue Recognition · Identification of the contract, or contracts, with a customer · Identification of the performance obligations in the contract · Determination of the transaction price · Allocation of the transaction price to the performance obligations in the contract · Recognition of revenue when, or as, performance obligations are satisfied Stock-Based Compensation ASC 718 requires the recognition of the fair value of stock compensation expense to be recognized over the vesting term of such award. The Company accounts for forfeitures as they occur. Uncertainties The Company has encountered challenges in procuring supplies of various materials and components, and electronic components in particular, due to well-documented shortages and constraints in the global supply chain. Lead times for ordered components may vary significantly, and some components used to manufacture our products are provided by a limited number of sources. The Company experienced lengthened lead times throughout its supply chain as a result of supply chain constraints and material shortages that have occurred through fiscal year 2023. This has been exacerbated by the recent resurgence of the COVID-19 pandemic in certain parts of China, which has resulted in the temporary closure of manufacturing facilities, including those that manufacture electronic parts that the Company includes in its products.

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	NOTE 3: REVENUE RECOGNITION The Company’s sales revenue is derived primarily from short term contracts with customers, which, on average, are in effect for less than twelve months. Sales revenue from manufactured equipment transferred at a single point in time accounts for a majority of the Company’s revenue. Sales revenue is recognized when control of the Company’s manufactured equipment is transferred to its customers in an amount that reflects the consideration the Company expects to receive based upon the agreed transaction price. The Company’s performance obligations are satisfied when its customers take control of the purchased equipment, in accordance with the contract terms. Based on prior experience, the Company reasonably estimates its sales returns and warranty reserves. Sales are presented net of discounts and allowances. Discounts and allowances are determined when a transaction is negotiated. The Company does not grant its customers or independent representatives the ability to return equipment nor does it grant price adjustments after a sale is complete. The Company does not capitalize any sales commission costs related to the acquisition of a contract. All commissions related to a performance obligation that are satisfied at a point in time are expensed when the customer takes control of the purchased equipment and revenue is recognized. The Company applies the practical expedient in paragraph ASC 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one-year or less. At February 28, 2023, the Company had received $ 2,838,000 145,000 145,000 At February 28, 2022, the Company had received $ 1,168,000 5,000 5,000 The Company’s sales revenue, by product line is as follows: Revenue recognition - sales revenue by product line Twelve Months Ended February 28, February 28, 2023 % of total 2022 % of total Fluxing Systems $ 1,179,000 8% $ 691,000 4% Integrated Coating Systems 1,114,000 7% 1,182,000 7% Multi-Axis Coating Systems 6,785,000 45% 9,912,000 58% OEM Systems 2,144,000 14% 2,381,000 14% Other 3,836,000 26% 2,967,000 17% TOTAL $ 15,058,000 $ 17,133,000

For qualified employees, except under certain circumstances specified in the plan or unless otherwise specified at the discretion of the Board of Directors, no option may be exercised prior to one year after date of grant, with the balance becoming exercisable in cumulative installments over a three-year period during the term of the option and terminating at a stipulated period of time after an employee's termination of employment.

The Company uses the Black-Scholes option pricing model to value its stock option awards. The assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. The expected term of the options is estimated based on the Company’s historical exercise rate. The expected life of awards that vest immediately use the contractual maturity since they are vested when issued. For stock price volatility, the Company uses its expected volatility of the price of the Company’s common stock based on historical activity. The risk-free interest rate is based on U.S. Treasury notes with a term approximating the expected life of the option at the grant-date. The weighted-average fair value of options has been estimated on the date of grant using the Black-Scholes options-pricing model. The weighted-average Black-Scholes assumptions are as follows: Stock-based compensation - weighted-average black-scholes assumptions Fiscal Year Ended February 28, February 28, Expected life 5 8 5 8 Risk free interest rate 2.82% 4.02% 0.78% 2.0% Expected volatility 55.02% 62.01% 50.73% 57.13% Expected dividend yield 0% 0%

INCOME TAXES	NOTE 10: INCOME TAXES The annual provision (benefit) for income taxes differs from amounts computed by applying the maximum U.S. Federal income tax rate of 21% to pre-tax income as follows: Income taxes - income tax reconciliation February 28, February 28, Expected federal income tax $ 165,882 $ 609,883 State tax, net of federal 37,204 37,894 Research and development tax credits (127,329 ) (101,573 ) Permanent differences 78,252 (179,320 ) Other — (5,253 ) Income tax expense $ 154,009 $ 361,631 Components of the current and deferred tax expense are as follows: Income taxes - current and deferred tax expense February 28, 2023 2022 Current: Federal $ 438,263 $ 341,882 State 83,525 38,536 Total current income tax 521,788 380,418 Deferred: Federal (321,458 ) (18,787 ) State (46,321 ) — Total deferred income tax (367,779 ) (18,787 ) Income tax expense $ 154,009 $ 361,631 In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and projections for future taxable income over periods in which the deferred tax assets are deductible. Management believes it is more likely than not that the Company will realize the benefits of these deductible differences. The incorporation of the new tax laws for 2023, requires the Company to capitalize for income tax purposes research and development expenses incurred during the year and for such expenses to be amortized over a five year period. As a result, a deferred tax asset “Capitalized R&D expenses – IRC Section 174” has been recorded. The Company does not have any uncertain tax positions in 2023. There are no interest and penalties related to uncertain tax positions in 2023. As of February 28, 2023, open years related to the federal and state jurisdictions are 2022, 2021 and 2020. The deferred tax asset and liability are comprised of the following: Income taxes - deferred tax asset and liability components February 28, February 28, Deferred tax asset Allowance for inventory $ 76,000 $ 69,000 Allowance for accounts receivable 3,000 12,000 Capitalized R&D expenses – IRC Section 174 441,000 — Accrued expenses and other 147,000 160,000 Deferred tax asset – Long Term $ 667,000 $ 241,000 Deferred tax liability Building and leasehold depreciation (83,000 ) (169,000 ) Deferred tax liability – Long Term $ (83,000 ) $ (169,000 )

Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair Value Measurement The carrying amounts of financial instruments reported in the accompanying consolidated financial statements for current assets and current liabilities approximate the fair value because of the immediate or short-term maturities of the financial instruments. The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below: Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities. The fair values of financial assets of the Company were determined using the following categories at February 28, 2023 and February 28, 2022, respectively: Significant accounting policies - fair values of financial assets of the company Level 1 Level 2 Level 3 Total Marketable Securities – February 28, 2023 $ 7,361,000 $ 729,000 $ — $ 8,090,000 Marketable Securities – February 28, 2022 $ 5,716,338 $ 151,652 $ — $ 5,867,990 Marketable Securities include certificates of deposit and US Treasury securities, totaling $ 8,090,000 5,867,990

Uncertainties	Uncertainties The Company has encountered challenges in procuring supplies of various materials and components, and electronic components in particular, due to well-documented shortages and constraints in the global supply chain. Lead times for ordered components may vary significantly, and some components used to manufacture our products are provided by a limited number of sources. The Company experienced lengthened lead times throughout its supply chain as a result of supply chain constraints and material shortages that have occurred through fiscal year 2023. This has been exacerbated by the recent resurgence of the COVID-19 pandemic in certain parts of China, which has resulted in the temporary closure of manufacturing facilities, including those that manufacture electronic parts that the Company includes in its products.
