Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes The Company's effective tax rate for the three months ended June 30, 2013 and 2012 differs from the statutory rate primarily due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, Canadian research and experimental development claims, the impact of stock option expense, and taxes on foreign income that differ from the U.S. tax rate. The Company utilizes the asset and liability method of accounting for income taxes. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based upon the Company's review of all positive and negative evidence, including its three year U.S. cumulative pre-tax book loss and taxable loss, it concluded that a full valuation allowance should continue to be recorded against its U.S. net deferred tax assets at June 30, 2013. In certain other foreign jurisdictions, where the Company does not have cumulative losses or other negative evidence, the Company had net deferred tax assets of $15.9 million and $16.5 million at June 30, 2013 and December 31, 2012. In the future, if the Company determines that it is more likely than not that it will realize its US net deferred tax assets, it will reverse the applicable portion of the valuation allowance and recognize an income tax benefit in the period in which such determination is made. The Company's unrecognized tax benefits and related interest and penalties during the three months ended June 30, 2013 increased by $90,000 primarily due to uncertain tax exposure in China. The ending balance for the unrecognized tax benefits was approximately $3.1 million at June 30, 2013. The related interest and penalties were $0.4 million and $0.3 million. The uncertain tax positions that are reasonably possible to decrease in the next twelve months are insignificant. The Company is currently under tax examination in India. The periods covered under examination are the Company's financial years 2005 through 2007 and 2009. The examination is in various stages of appellate proceedings and all material uncertain tax positions associated with the examination have been taken into account in the ending balance of the unrecognized tax benefits at June 30, 2013. As of June 30, 2013, the Company is not under examination by tax authorities in any other jurisdictions.
