Concentration Risk Disclosure [Text Block]	NOTE 3: CONCENTRATION OF CREDIT RISK Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Company places its cash and cash equivalents with high credit-quality domestic financial institutions and invests its excess cash primarily in savings accounts, treasury bills and money market instruments. The Company performs periodic evaluations of the relative credit standing of all such institutions as it seeks to maintain stability and liquidity. From time to time, these cash investments may exceed the Federal Deposit Insurance Corporation limit, which at March 31, 2015 and December 31, 2014 was approximately $7,156,000 and $10,216,000, respectively. The Company sells products and services to various companies across several industries in the ordinary course of business. The Company performs ongoing credit evaluations to assess the probability of accounts receivable collection based on a number of factors, including past transaction experience, evaluation of their credit history and review of the invoicing terms of the contract to determine the financial strength of its customers. The Company also maintains allowances for anticipated losses.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
