| Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
| Apr. 30, 2019 |
| Notes to Financial Statements | |
| Cash | The
Company maintains all of its cash in bank deposit accounts, which at times may exceed federally insured limits. No losses have
been experienced on such accounts. All cash is held with Bank of America, N.A., and BMO Harris, N.A. |
| Receivables | Receivables
are carried at original invoice less estimates made for doubtful receivables. Management determines the allowance for doubtful
accounts by reviewing and identifying troubled accounts on a periodic basis by using historical experience applied to an aging
of accounts. A receivable is considered to be past due if any portion of the receivable balance is outstanding beyond the stipulated
due date. Receivables are written off when deemed uncollectible. Recoveries of receivables previously written off are recorded
when received. |
| Inventories | Inventories
are valued using the FIFO (first-in, first-out) method at the lower of cost or market. |
| Depreciation and Amortization | Equipment
and leasehold improvements are stated at cost. Depreciation is computed primarily using the straight-line method over the estimated
useful lives of the respective assets. Repairs and maintenance are charged to expense as incurred. Renewals and betterments, which
significantly extend the useful lives of existing equipment, are capitalized. Significant leasehold improvements are capitalized
and amortized over ten years or the term of the lease, if shorter. Equipment is depreciated over three to ten years. |
| Prepaid Expenses | Certain
expenses, primarily insurance and income taxes, have been prepaid and will be used within one year. |
| Revenue Recognition | In May 2014,
the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)", which supersedes the revenue recognition
requirements in Accounting Standards Codification (ASC) 605, Revenue Recognition The Company
adopted this standard on May 1, 2018, using the modified retrospective approach. The impact of the adoption of ASU 2014-09 on the
Company’s condensed consolidated financial statements is as follows:
· The Company’s revenue is primarily generated from the sales of products directly to customers
or through distribution channels, based on purchase orders and not supply contracts providing for additional goods or services
once the products are transferred to the customer. The Company’s performance obligations underlying such sales, and the timing
of revenue recognition related thereto, remain substantially unchanged following the adoption of this ASU.
· The adoption of ASU No. 2014-09 requires that the Company recognize its sales return allowance
on a gross basis rather than as a net liability. As such, the Company now recognizes a return asset for the right to recover the
goods returned by the customer, measured at the former carrying amount of the products, less any expected recovery costs (recorded
as an increase to prepaid expenses and other current assets), and a return liability for the amount of expected returns (recorded
as an increase to other current liabilities), and the Company’s analysis of sales returns over the past several years noted
that sales returns are nominal and therefore no sales return allowance is deemed necessary. There was
no adjustment necessary for fiscal year ending April 30, 2018 or prior in relation to the change in the revenue recognition policy
and no significant effects on the fiscal year ending April 30, 2019. |
| Shipping and Handling | Shipping and
handling fees billed to customer, if any, are netted against the related costs which are included in cost of sales. The net cost
is not material. |
| Income Taxes | Income
taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due
and deferred taxes related primarily to differences in the methods of accounting for patents, inventories, certain accrued expenses
and bad debt expenses for financial and income tax reporting purposes. The deferred income taxes represent the future tax consequences
of those differences, which will be taxable in the future. See Note 4 for additional information regarding income taxes. The
Company files tax returns in the U.S. federal jurisdiction and with the state of Illinois. Various tax years remain open to examinations,
generally for three years after filing, although there are currently no ongoing tax examinations. Management’s policy is
to recognize interest and penalties related to uncertain tax positions in income tax expense. Management does not believe that
there are any uncertain tax positions as of April 30, 2019. |
| Leases | The
Company accounts for leases under ASC 842. Lease arrangements are determined at the inception of the contract. Operating
leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease
liabilities on the Company’s balance sheets. Finance leases are included in property and equipment, other current liabilities,
and other long-term liabilities on our balance sheets. |
| Research and Development and Patents | Research
and development expenditures are charged to operations as incurred. The costs of obtaining patents, primarily legal fees, are
capitalized and, once obtained, are amortized over the life of the respective patent using the straight-line method. Patents
relate to products that have been developed and are being marketed by the Company. Patents pending relate to products under development. |
| Use of Estimates | The
preparation of financial statements in conformity with accounting principles generally accepted in the United States of America
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 financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates. |
| Income Per Common Share | Income
per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period.
Basic and diluted net income per common share is the same for the years ended April 30, 2019 and 2018 as there are no common stock
equivalents. |
| Fair Value of Financial Instruments | The
Company evaluates its financial instruments based on current market interest rates relative to stated interest rates, length to
maturity and the existence of readily determinable market prices. Based on the Company’s analysis, the fair value of financial
instruments recorded on the balance sheets as of April 30, 2019 and 2018, approximates their carrying value. |
| Segments | Accounting
standards have established annual reporting standards for an enterprise’s operating segments and related disclosures about
its products, services, geographic areas and major customers. The Company’s
operations were a single reportable segment and an international segment. The international segment operations are immaterial. |
| Recent Accounting Pronouncements | The
FASB issues ASUs to amend the authoritative literature in Accounting Standards Certification (ASC). There have been a number of
ASUs to date that amend the original text of ASCs. Except for the ASUs issued to date either (i) provide supplemental guidance,
(ii) are technical corrections, (iii) are not applicable to the Company or (iv) are not expected to have a significant impact
on the Company. |
