Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax provision for the three months ended April 1, 2012 was $10.6 million or an effective tax rate of 29.6% compared to the tax provision for the three months ended April 3, 2011 of $9.1 million or an effective tax rate of 30.1%. The income tax expense increased for the three months ended April 1, 2012 compared to April 3, 2011 was due to higher pre-tax earnings for the three months ended April 1, 2012. The decrease in the effective tax rate for the three month period ended April 1, 2012, compared to the same period in the prior year was primarily caused by higher forecasted pre-tax earnings in foreign jurisdictions with tax rates lower than the U.S. federal rate. This decrease was partially offset by the expiration of the U.S. research tax credit that is no longer available after December 31, 2011. The Company has recorded its liability for uncertain tax positions as part of its long-term liability as payments are not anticipated over the next 12 months. The existing tax positions of the Company continue to generate an increase in the liability for uncertain tax positions. 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 liabilities for uncertain tax positions in multiple jurisdictions in the next 12 months is approximately $0.8 million, excluding the interest, penalties and the effect of any related deferred tax assets or liabilities.
