Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	Goodwill and Other Intangibles In accordance with ASC 350 Intangibles - Goodwill and Other, goodwill and intangibles with indefinite lives are not amortized, but instead measured for impairment at least annually or when events indicate that impairment exists. No events occurred during the nine months ended September 30, 2011 indicating impairment of goodwill existed, and accordingly, there was no change in the carrying balance of goodwill during that period. Goodwill is recorded at the subsidiary level in local currencies and converted into U.S. dollars at the balance sheet date. There was an unrealized gain of $0.7 million during the nine months ended September 30, 2011 due to the change in foreign currency rates from December 31, 2010 to September 30, 2011. The unrealized gain arising from the translation adjustment is recorded in accumulated other comprehensive income on the Balance Sheet. Other intangibles consist of intellectual property purchased by the Company's subsidiary located in Geneva, Switzerland, Creative Electronic Systems, S.A. ("CES"). Amortization of other intangible assets was $38,000 and $88,000 for the three and nine months ended September 30, 2011.
