Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.

The unaudited financial information furnished herein reflects all adjustments, consisting of normal recurring items that, in the opinion of management, are necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods. The results of operations for the three and nine months ended November 30, 2024 are not necessarily indicative of the results to be expected for the year ending February 28, 2025.

The information included in this Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended February 29, 2024.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The consolidated condensed financial statements are prepared in accordance with U.S. GAAP. Preparation of these consolidated condensed financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable. The Company could have reasonably used different accounting estimates. This applies in particular to inventory and valuation allowance for deferred tax assets. Actual results could differ significantly from our estimates. To the extent that there are material differences between these estimates and actual results, the Company’s future financial statement presentation, financial condition, results of operations and cash flows will be affected.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and money market accounts. The Company considers any short-term, highly liquid investments with maturities of three months or less as cash and cash equivalents.

Investment, Policy [Policy Text Block]

Investment in Marketable Securities

Investment in Securities includes investments in equity securities. Investments in securities are reported at fair value with changes in unrecognized gains or losses included in other income on the condensed consolidated statements of operations.

The following table summarizes the Company’s marketable securities:

November 30, 2024			Gross		Gross
			Unrealized		Unrealized
Marketable Securities:	Cost		Gains		Losses			Fair Value
Common Stocks	$	574,000	$	454,000	$	(5,000	)	$	1,023,000

February 29, 2024			Gross		Gross
			Unrealized		Unrealized
Marketable Securities:	Cost		Gains		Losses			Fair Value
Common Stocks	$	581,000	$	375,000	$	(52,000	)	$	904,000

At November 30, 2024 and February 29, 2024, the deferred tax liability related to unrecognized gains and losses on short-term investments was approximately $119,000 and $86,000, respectively.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments

Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements and Disclosures”, defines “fair value” as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.  ASC 820 also sets forth a valuation hierarchy of the inputs (assumptions that market participants would use in pricing an asset or liability) used to measure fair value.  This hierarchy prioritizes the inputs into the following three levels:

Level 1: Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities traded in active markets.

Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3: Inputs that are generally unobservable. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

The table below shows the Company’s marketable securities as of November 30, 2024 and February 29, 2024:

November 30, 2024	Level 1		Level 2		Level 3		Total
Common Stocks	$	1,023,000	$	-	$	-	$	1,023,000

February 29, 2024	Level 1		Level 2		Level 3		Total
Common Stocks	$	904,000	$	-	$	-	$	904,000

The carrying amounts of the Company’s short-term financial instruments, including accounts receivable, accounts payable, accrued expenses and other liabilities approximate their fair value due to the relatively short period to maturity for these instruments. The carrying value of long-term debt approximates fair value since the related rates of interest approximate current market rates.

Receivable [Policy Text Block]

Accounts Receivable

Accounts receivable are stated at amounts management expects to collect from outstanding balances and do not bear interest. The Company regularly monitors and assesses its risk of not collecting amounts owed by customers. At each balance sheet date, the Company recognizes an expected allowance for credit losses. In addition, at each reporting date, this estimate is updated to reflect any changes in credit risk since the receivable was initially recorded. This estimate is calculated on a pooled basis where similar risk characteristics exist. If applicable, accounts receivable are evaluated individually when they do not share similar risk characteristics which could exist in circumstances where amounts are considered at risk or uncollectible. The accounts receivable balance as of November 30, 2024, and February 29, 2024, was $1,793,000 and $2,826,000, respectively.

The allowance estimate is derived from a review of the Company’s historical losses based on the aging of receivables. This estimate is adjusted for management’s assessment of current conditions, reasonable and supportable forecasts regarding future events, and any other factors deemed relevant by the Company. The Company believes historical loss information is a reasonable starting point in which to calculate the expected allowance for credit losses as the Company’s portfolio segment has remained consistent since the Company’s inception. The allowance for credit losses was $0 as of November 30, 2024, and February 29, 2024.

The Company writes off receivables when there is information that indicates the debtor is facing significant financial difficulty and there is no possibility of recovery. If any recoveries are made from any accounts previously written off, they will be recognized in income (or an offset to credit loss expense) in the year of recovery, in accordance with the Company’s accounting policy election. The total amount of write-offs for the nine months ended November 30, 2024, and  November 30, 2023 was $0.

Shipping And Handling Costs [Policy Text Block]

Shipping and Handling

Shipping and handling costs billed to customers are recorded in net sales. Shipping costs incurred by the Company are recorded in cost of sales.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are stated at the lower of cost and net realizable value. Cost is determined using the “first-in, first-out” (FIFO) method. The Company buys raw material only to fill customer orders. Excess raw material is created only when a vendor imposes a minimum quantity buy in excess of actual requirements. Such excess material will usually be utilized to meet the requirements of the customer’s subsequent orders. If excess material is not utilized after two fiscal years it is fully reserved. Any inventory item once designated as reserved is carried at zero value in all subsequent valuation activities.

The Company does not classify a portion of inventories as non-current since we cannot reasonably estimate based on the length of our operating cycle which items will or will not be used within twelve months.

The Company’s inventory valuation policy is as follows:

Raw material /Work in process:	All material acquired or processed in the last two fiscal years is valued at the lower of its acquisition cost or net realizable value, except for wafers which function under a three- year policy. All material not used after two fiscal years is fully reserved for except wafers which were reserved for after three years. All raw wafers were fully reserved for when the wafer fab was decommissioned. Finished wafers produced in our former wafer fab are stored in the wafer bank and are considered work-in-process. Raw material in excess of five years’ usage that cannot be restocked, and slow-moving work in process are reserved for.
Finished goods:	All finished goods with firm orders for later delivery are valued at the lower of cost or net realizable value. All finished goods with no orders are fully reserved.
Direct labor costs:	Direct labor costs are allocated to finished goods and work in process inventory based on engineering estimates of the number of man-hours required from the different direct labor departments to bring each device to its particular level of completion.

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

Property, Plant, Equipment, and Leasehold Improvements

Property, plant, and equipment is recorded at cost. Major renewals and improvements are capitalized, while maintenance and repairs that do not extend their expected life are expensed as incurred. Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the lease term or the lives of the related assets:

Building (years)		39
Building Improvements (years)		15
Leasehold Improvements	Shorter of 10 years or life of lease
Machinery and Equipment (years)		5

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of Credit Risk

Financial instruments, which potentially subject the Company to concentration of credit risk, consist principally of cash and account receivables. The Company places its cash with high credit quality institutions. At times, such amounts may be in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. The Company has not experienced any losses in such accounts and believes that it is not exposed to any significant credit risk on the accounts. As of November 30, 2024, all non-interest bearing checking accounts were FDIC insured to a limit of $250,000. Deposits in excess of FDIC insured limits were approximately $677,000 at November 30, 2024, as compared to $1,007,000 at February 29, 2024. With respect to the account receivables, most of the Company’s products are custom made pursuant to contracts with customers whose end-products are sold to the United States Government. The Company performs ongoing credit evaluations of its customers’ financial condition and maintains allowances for potential credit losses. Actual losses and allowances have historically been within management’s expectations.

Earnings Per Share, Policy [Policy Text Block]

Net Income (Loss) Per Common Share

Net income (loss) per common share is presented in accordance with ASC 260-10 “Earnings per Share.” Basic earnings per common share are computed using the weighted average number of common shares outstanding during the period. Diluted earnings per common share incorporate the incremental shares issuable upon the assumed exercise of stock options to the extent they are not anti-dilutive using the treasury stock method. The Company had no common stock equivalents outstanding during the three and nine months ended November 30, 2024 and November 30, 2023; therefore, there is no effect from dilution on earnings per share.

Revenue from Contract with Customer [Policy Text Block]

Revenue Recognition

The Company records revenue in accordance with ASC Topic 606, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods and services to customers. Revenue is recognized at a point in time, generally upon shipment of products to customers.

The core principle of the guidance in Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

To achieve that core principle, the Company applied the following steps:

1. Identify the contract(s) with a customer.

The Company designs, develops, manufactures and markets solid-state semiconductor components and related devices. The Company’s products are used as components primarily in the military and aerospace markets.

The Company’s revenues are from purchase orders and/or contracts with customers associated with manufacture of products. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

2. Identify the performance obligations in the contract.

The majority of the Company’s purchase orders or contracts with customers contain a single performance obligation, the shipment of products.

3. Determine the transaction price.

The transaction price reflects the Company’s expectations about the consideration it will be entitled to receive from the customer at a fixed price per unit shipped based on the terms of the contract or purchase order with the customer. To the extent our actual costs vary from the fixed price that was negotiated, we will generate more or less profit or could incur a loss.

4. Allocate the transaction price to the performance obligations in the contract.

5. Recognize revenue when (or as) the Company satisfies a performance obligation.

This performance obligation is satisfied when control of the product is transferred to the customer, which generally occurs upon shipment. The Company receives purchase orders for products to be delivered over multiple dates that may extend across reporting periods. The Company’s accounting policy treats shipping and handling activities as a fulfillment cost. The Company invoices for each delivery upon shipment and recognizes revenues at the fixed price for each distinct product delivered when transfer of control has occurred, which is generally upon shipment.

In addition, the Company may have a contract or purchase order to provide a non-recurring engineering service to a customer. These contracts are reviewed, performance obligations are determined, and we recognize revenue at the point in time in which each performance obligation is fully satisfied.

We recognize revenue on sales to distributors when the distributor takes control of the products ("sold-to" model).  We have agreements with distributors that allow distributors a limited credit for unsaleable products, which we refer to as a "scrap allowance." Consistent with industry practice, we also have a "stock, ship and debit" program whereby we consider requests by distributors for credits on previously purchased products that remain in distributors' inventory, to enable the distributors to offer more competitive pricing.  We have contractual arrangements whereby we provide distributors with protection against price reductions initiated by us after product is sold by us to the distributor and prior to resale by the distributor. In addition, we have a termination clause in one of our distributor agreements that would allow for a full credit for all inventory upon 60 days’ notice of terminating the agreement.

We recognize the estimated variable consideration to be received as revenue and record a related accrued expense for the consideration not expected to be received, based upon an estimate of product returns, scrap allowances, "stock, ship and debit" credits, and price protection credits that will be attributable to sales recorded through the end of the period.  We make these estimates based upon sales levels to our customers during the period, inventory levels at the distributors, current and projected market conditions, and historical experience under the programs. Our estimates require the exercise of significant judgments.  We believe that we have a reasonable basis to estimate future credits under the programs.

Related Party Transactions [Policy Text Block]

Related Party Transactions

The Company currently purchases and has purchased in the past die and wafers, as specified by the Company's customers, from ES Components. Mr. Aubrey, a director of the Company is a minority owner, and an immediate family member of the majority owner of ES Components. For the three and nine months ended November 30, 2024, the Company purchased $0 and $90,000 of die, respectively and $0 of used equipment from ES Components. For the three and nine months ended November 30, 2023, the Company purchased $24,000 and $57,000 of die, respectively and $0 of used equipment from ES Components. The Company has included the expenses related to die in cost of goods sold in the accompanying condensed consolidated statements of operations. The Company occasionally makes sales to ES Components. For the three and nine months ended November 30, 2024 and November 30, 2023, sales were $0.

Share-Based Payment Arrangement [Policy Text Block]

Stock based Compensation

The Company records stock-based compensation in accordance with the provisions of ASC Topic 718, "Compensation-Stock Compensation," which establishes accounting standards for transactions in which an entity exchanges its equity instruments for goods or services. Under ASC Topic 718, the Company recognizes an expense for the fair value of outstanding stock options and grants as they vest, whether held by employees or others. No vesting of stock options or grants occurred during the three and nine months ended November 30, 2024 or November 30, 2023.
