Disclosure Text Block Supplement [Abstract]
Preferred Stock [Text Block]	Note 13 – Series A 8% Convertible Preferred Stock On November 14, 2017, the Company entered into definitive subscription agreements with an accredited investor, pursuant to which the investor purchased an aggregate of 500,000 shares of the Company’s Series A Convertible Preferred Stock (the “Series A Preferred”) for an aggregate of $3 million. The Company used $2,000,000 of the proceeds to be placed in a restricted cash account to secure a letter of credit which was used for collateral for the appeal bond (See Notes 5 and 15) and the remaining amount was used for working capital purposes, and for payment of fees and expenses associated with this transaction. The Closing occurred following the satisfaction of customary closing conditions. The securities issued pursuant to the Subscription Agreements were not registered under the Securities Act of 1933, as amended (the “Securities Act”), but qualified for exemption under Section 4(a)(2) of the Securities Act. The securities were exempt from registration under Section 4(a)(2) of the Securities Act because the issuance of such securities by the Company did not involve a “public offering,” as defined in Section 4(a)(2) of the Securities Act, due to the insubstantial number of persons involved in the transaction, size of the offering, manner of the offering and number of securities offered. The Company did not undertake an offering in which it sold a high number of securities to a high number of investors. In addition, these shareholders had the necessary investment intent as required by Section 4(a)(2) of the Securities Act since they agreed to, and received, share certificates bearing a legend stating that such securities are restricted pursuant to Rule 144 of the Securities Act. This restriction ensures that these securities would not be immediately redistributed into the market and therefore not be part of a “public offering.” Based on an analysis of the above factors, the Company has met the requirements to qualify for exemption under Section 4(a)(2) of the Securities Act. The shares of Series A Preferred have a stated value of $6.00 per share (the “Series A Stated Value”) and are convertible into Common Stock at a price of $3.00 per share. The holders of shares of the Series A Preferred shall be entitled to receive dividends out of any assets legally available, to the extent permitted by New Jersey law, at an annual rate equal to 8% of the Series A Stated Value of such shares of Series A Preferred, calculated on the basis of a 360 day year, consisting of twelve 30-day months, and shall accrue from the date of issuance of such shares of Series A Preferred, payable quarterly in cash. Any unpaid dividends shall accrue at the same rate. To the extent not paid on the last day of March, June, September and December of each calendar year, all dividends on any share of Series A Preferred shall accumulate whether or not declared by the Board and shall remain accumulated dividends until paid. As of December 31, 2018, the Company has accrued $330,667 for dividends. The Holders will vote together with the holders of the Company’s Common Stock on an as-converted basis on each matter submitted to a vote of holders of Common Stock (whether at a meeting of shareholders or by written consent). Effective beginning on the third anniversary of the Original Issue Date, and upon 30 days’ written notice to the Holders of Series A Preferred, the Company may, in its sole discretion, redeem the Series A Preferred at the aggregate Series A Stated Value plus any accrued and accumulated but unpaid dividends. The Company has also evaluated its convertible preferred stock in accordance with the provisions of ASC 815, Derivatives and Hedging, including consideration of embedded derivatives requiring bifurcation. The issuance of the convertible preferred stock could generate a beneficial conversion feature (“BCF”), which arises when a debt or equity security is issued with an embedded conversion option that is beneficial to the investor or in the money at inception because the conversion option has an effective strike price that is less than the market price of the underlying stock at the commitment date. The Series A Convertible Preferred Stock, and the associated dividends, did not generate a BCF upon issuance as the fair value of the Company's common stock was greater than the conversion price. During the quarter December 31, 2018 the Company measured a BCF based on the fair value of our stock price on the date dividends were declared. The BCF amounted to $16,200 on the associated dividend.
