Foreign Exchange Instruments [Abstract]
Foreign Exchange Instruments	Note 5. Foreign Exchange Instruments During the quarter ended June 30, 2011, we entered into a foreign currency forward-exchange contract in an effort to minimize the risk of future fluctuations in the exchange rates between Australian dollars and Japanese Yen. The foreign currency forward-exchange contract was directly related to an asset purchase commitment by our Australian subsidiary. We do not utilize derivative financial instruments for speculative or trading purposes. As of June 30, 2011, the forward contract to sell Australian dollars to Japanese Yen had a notional value of AU$858,000 and an exchange rate of one Australian dollar to 83.35 Japanese Yen. During the quarter ended June 30, 2011, the realized fair value of this forward exchange contract resulted in an expense of $16,000, which is included in other, net on the condensed consolidated statements of operations.
