Liquidity Disclosure [Policy Text Block]	2. Liquidity The Company’s principal sources of liquidity are cash and cash equivalents of approximately $1,651,000 at June 30, 2012, the $2,500,000 available on the $3,000,000 credit facility detailed below and cash from operations. The Company sustained a net loss of $1,323,000 for the six months ended June 30, 2012, and had working capital of $3,192,000 at June 30, 2012. The Company’s business operations have been primarily funded over the past three years through private placements of our capital stock. In 2010, we also entered into a $3,000,000 line of credit. As of June 30, 2012, the outstanding balance on the line of credit was $500,000. The Company may require additional funding and this funding will depend, in part, on the timing and structure of potential business arrangements. If necessary, the Company may continue to seek to raise additional capital through the sale of its equity. It may be accomplished via a strategic alliance with a third party. There may also be additional acquisition and growth opportunities that may require external financing. There can be no assurance that such financing will be available on terms acceptable to the Company, or at all. We also have the ability to defer certain product development and other programs, if necessary. We believe that our existing capital resources will be sufficient to support our current business plan beyond August 2013.

- Definition

Disclosure of accounting policy for reporting when there is a substantial doubt about an entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date). Disclose: (a) pertinent conditions and events giving rise to the assessment of substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time, (b) the possible effects of such conditions and events, (c) management's evaluation of the significance of those conditions and events and any mitigating factors, (d) possible discontinuance of operations, (e) management's plans (including relevant prospective financial information), and (f) information about the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities. If management's plans alleviate the substantial doubt about the entity's ability to continue as a going concern, disclosure of the principal conditions and events that initially raised the substantial doubt about the entity's ability to continue as a going concern would be expected to be considered. Disclose whether operations for the current or prior years generated sufficient cash to cover current obligations, whether waivers were obtained from creditors relating to the company's default under the provisions of debt agreements and possible effects of such conditions and events, such as: whether there is a possible need to obtain additional financing (debt or equity) or to liquidate certain holdings to offset future cash flow deficiencies. Disclose appropriate parent company information when parent is dependent upon remittances from subsidiaries to satisfy its obligations.
