Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax provision for the three and nine months ended September 30, 2012 was $9.9 million or an effective tax rate of 29.4% and $30.4 million or an effective tax rate of 30.2%, respectively. The income tax provision for the three and nine months ended October 2, 2011 was $6.2 million or an effective tax rate of 18.8% and $22.1 million or an effective tax rate of 24.4%, respectively. The increase in the effective tax rate for the three and nine month periods ended September 30, 2012, compared to the same period in the prior year was primarily caused by an increase in the mix of forecasted earnings from countries with relatively higher statutory tax rates. Additionally, the expiration of the federal research tax credit as of December 31, 2011 contributed to the increased effective tax rate for the respective periods. These increases were partially offset by a reduction in accruals for uncertain tax positions that were remeasured during the three month period ended September 30, 2012. The Company has recorded the portion of its liability for uncertain tax positions that are not expected to be paid over the next 12 months as part of its long-term liability. The existing tax positions of the Company continue to generate an increase in the liability for uncertain tax positions. The Company is under examination in various US and foreign jurisdictions including by the U.S. Internal Revenue Service. The examination by the Internal Revenue Service includes the 2008 and 2009 calendar years. The liability for uncertain tax positions may be reduced for liabilities that are settled with taxing authorities or on which the statute of limitations could expire without assessment from tax authorities. The possible reduction in uncertain tax positions in multiple jurisdictions that may impact the statement of operations in the next 12 months is approximately $1.9 million, excluding interest, penalties and the effect of any related deferred tax assets or liabilities.
