Principles of Consolidation The consolidated financial statements include the accounts of the Parent, and its wholly-owned subsidiaries, which include SES and Arkados. Intercompany accounts and transactions have been eliminated in consolidation. Revenue Recognition Arkados The Company enters into arrangements with end users for items which may no Revenues from software licensing are recognized in accordance with Accounting Standards Codification (“ASC”) 985 605, License revenues are recognized at the time of delivery of the software and all other revenue recognition criteria discussed above have been met. Deferred revenue represents license revenues billed but not SES Sales of products are recognized when the products are shipped and the customer takes risk of ownership and assumes the risk of loss. Service revenue is recognized when the service is completed. Deferred revenue represents revenues billed but not Cash and Cash Equivalents The Company considers investments in highly liquid instruments with a maturity of three not May 31, 2018 2017. Accounts Receivable Accounts receivable are reported at their outstanding unpaid principal balances net of allowances for uncollectible accounts. The Company provides for allowances for uncollectible receivables based on management’s estimate of uncollectible amounts considering age, collection history, and any other factors considered appropriate. The Company writes off accounts receivable against the allowance for doubtful accounts when a balance is determined to be uncollectible. At May 31, 2018 2017, $676,000 $0. Fair Value of Financial Instruments The carrying value of cash, accounts receivable, other receivables, accounts payable and accrued expenses approximate their fair values based on the short-term maturity of these instruments. The carrying amounts of debt were also estimated to approximate fair value. As defined in ASC 820, 820 1 3 The three 820 ● Level 1 1 ● Level 2 1, 2 ● Level 3 may Earnings (Loss) Per Share (“EPS”) Basic EPS is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding. Diluted EPS includes the effect from potential issuance of common stock, such as stock issuable pursuant to the exercise of stock options and warrants and the assumed conversion of convertible notes. The following table summarizes the securities that were excluded from the diluted per share calculation because the effect of including these potential shares was antidilutive even though the exercise price could be less than the average market price of the common shares: Year ended May 31, 2018 2017 Convertible notes 9,841,101 3,389,437 Stock options 6,520,834 7,437,500 Warrants 7,260,641 10,474,871 Potentially dilutive securities 23,622,576 21,301,808 Stock Based Compensation In computing the impact, the fair value of each option and/or warrant is estimated on the date of grant based on the Black-Scholes options-pricing model utilizing certain assumptions for a risk-free interest rate; volatility; and expected remaining lives of the awards. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. In estimating the Company’s forfeiture rate, the Company analyzed its historical forfeiture rate, the remaining lives of unvested options, and the amount of vested options as a percentage of total options outstanding. If the Company’s actual forfeiture rate is materially different from its estimate, or if the Company reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period. During the year ended May 31, 2018, 1,220,000 $954,775 . 310,000 $179,800 May 31, 2017, 208,596 $253,003 610,000 $511,300 $590,661 no May 31, 2017. Stock based compensation expense for the years ended May 31, 2018 2017 $1,574,125 $439,500 $511,300, Stock based compensation expense related to stock options for the year ended May 31, 2018 2017 $976,240 $590,661, Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity-based transactions and disclosure of contingent liabilities at the date of the financial statements and revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company believes the following critical accounting policies affect its more significant judgments and estimates used in the preparation of the financial statements. Significant estimates include the allowance for doubtful accounts, the useful life of plant and equipment and intangible assets, deferred tax asset and valuation allowance, and assumptions used in Black-Scholes-Merton, or BSM, valuation methods, such as expected volatility, risk-free interest rate, and expected dividend rate. Property and Equipment Property and equipment is recorded at cost. Depreciation is computed using straight-line and accelerated methods over the estimated useful lives of the related assets. Expenditures that enhance the useful lives of the assets are capitalized and depreciated. Maintenance and repairs are expensed as incurred. When properties are retired or otherwise disposed of, related costs and related accumulated depreciation are removed from the accounts. Research and Development All research and development costs are expensed as incurred. Deferred Financing Costs Costs incurred in connection with obtaining financing are deferred and amortized on a straight-line basis over the term of the related loan. Convertible Instruments The Company evaluates and accounts for conversion options embedded in its convertible instruments in accordance with accounting standards for “Accounting for Derivative Instruments and Hedging Activities.” Accounting standards generally provides three three not not The Company accounts for convertible instruments (when it has determined that the embedded conversion options should not ASC 815 40 not Reclassifications Certain reclassifications have been made to conform the prior period data to the current presentations.

Receivables, Policy [Policy Text Block]	Accounts Receivable Accounts receivable are reported at their outstanding unpaid principal balances net of allowances for uncollectible accounts. The Company provides for allowances for uncollectible receivables based on management’s estimate of uncollectible amounts considering age, collection history, and any other factors considered appropriate. The Company writes off accounts receivable against the allowance for doubtful accounts when a balance is determined to be uncollectible. At May 31, 2018 2017, $676,000 $0.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments The carrying value of cash, accounts receivable, other receivables, accounts payable and accrued expenses approximate their fair values based on the short-term maturity of these instruments.

Earnings Per Share, Policy [Policy Text Block]	Earnings (Loss) Per Share (“EPS”) Basic EPS is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding. Diluted EPS includes the effect from potential issuance of common stock, such as stock issuable pursuant to the exercise of stock options and warrants and the assumed conversion of convertible notes. The following table summarizes the securities that were excluded from the diluted per share calculation because the effect of including these potential shares was antidilutive even though the exercise price could be less than the average market price of the common shares: Year ended May 31, 2018 2017 Convertible notes 9,841,101 3,389,437 Stock options 6,520,834 7,437,500 Warrants 7,260,641 10,474,871 Potentially dilutive securities 23,622,576 21,301,808
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock Based Compensation In computing the impact, the fair value of each option and/or warrant is estimated on the date of grant based on the Black-Scholes options-pricing model utilizing certain assumptions for a risk-free interest rate; volatility; and expected remaining lives of the awards. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. In estimating the Company’s forfeiture rate, the Company analyzed its historical forfeiture rate, the remaining lives of unvested options, and the amount of vested options as a percentage of total options outstanding. If the Company’s actual forfeiture rate is materially different from its estimate, or if the Company reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period. During the year ended May 31, 2018, 1,220,000 $954,775 . 310,000 $179,800 May 31, 2017, 208,596 $253,003 610,000 $511,300 $590,661 no May 31, 2017.

Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity-based transactions and disclosure of contingent liabilities at the date of the financial statements and revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company believes the following critical accounting policies affect its more significant judgments and estimates used in the preparation of the financial statements. Significant estimates include the allowance for doubtful accounts, the useful life of plant and equipment and intangible assets, deferred tax asset and valuation allowance, and assumptions used in Black-Scholes-Merton, or BSM, valuation methods, such as expected volatility, risk-free interest rate, and expected dividend rate.
Inventory, Policy [Policy Text Block]	Property and Equipment Property and equipment is recorded at cost. Depreciation is computed using straight-line and accelerated methods over the estimated useful lives of the related assets. Expenditures that enhance the useful lives of the assets are capitalized and depreciated. Maintenance and repairs are expensed as incurred. When properties are retired or otherwise disposed of, related costs and related accumulated depreciation are removed from the accounts.
Property, Plant and Equipment, Policy [Policy Text Block]	Research and Development All research and development costs are expensed as incurred.
Deferred Charges, Policy [Policy Text Block]	Deferred Financing Costs Costs incurred in connection with obtaining financing are deferred and amortized on a straight-line basis over the term of the related loan.
Derivatives, Policy [Policy Text Block]	Convertible Instruments The Company evaluates and accounts for conversion options embedded in its convertible instruments in accordance with accounting standards for “Accounting for Derivative Instruments and Hedging Activities.” Accounting standards generally provides three three not not The Company accounts for convertible instruments (when it has determined that the embedded conversion options should not ASC 815 40 not
