Deconsolidation of Giantec [Abstract]
Equity Method Investments Disclosure [Text Block]	Deconsolidation of Giantec On December 30, 2010, Giantec received an additional direct investment of $3.75 million from Shanghai Pudong Science and Technology Co., Ltd. and $250,000 from Super Solution Limited, both of which were unrelated parties at the time of their investment in Giantec, and as a result the Company’s ownership interest was reduced to approximately 44% and the Company was required to deconsolidate Giantec and to record its retained interest in Giantec at fair value at the date of deconsolidation. As the additional investment received by Giantec was from new investors, the Company used the price paid by the new investors as a basis for determining the fair value of its investment in Giantec. As a result, the Company recorded a loss of approximately $30,000 in “Interest and other income, net,” which was the difference between the fair value of the Company’s retained interest in Giantec, and the carrying value of Giantec’s net assets and noncontrolling interest before the deconsolidation. After the deconsolidation, the Company accounts for Giantec under the equity method and its investment in Giantec is included in Long-term investments on the Company's Balance sheets.
