Basis Of Presentation [Abstract]
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Fair Value Measurement - In May 2011, the Financial Accounting Standards Board ("FASB") issued guidance which generally provides a consistent definition of fair value and ensures that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. The guidance changes certain fair value measurement principles and enhances the disclosure requirements, particularly for Level 3 fair value measurements. This guidance was effective for interim and annual reporting periods beginning after December 15, 2011 and was applied on a prospective basis. The Company adopted the guidance on January 1, 2012, as required. There was no material impact on the Consolidated Financial Statements resulting from the adoption, see Note 3 Fair Value Measurements for additional disclosures related to this pronouncement. Comprehensive Income - In June 2011, the FASB issued ASU No. 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income," ("ASU 2011-05"). ASU 2011-05 eliminates the option to report other comprehensive income (loss) and its components in the statement of changes in equity and requires that all nonowner changes in stockholders' equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. We adopted this guidance in the first quarter of 2012 and applied it retrospectively. To implement this standard we have added a separate statement labeled Condensed Consolidated Statement of Comprehensive Income (Loss). Intangibles – Goodwill and Other: In September 2011, the FASB issued ASU No. 2011-08, "Intangibles – Goodwill and Other (Topic 350) ("ASU 2011-08"). The amendments in this update will allow an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under these amendments, an entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment. This new guidance was adopted and applied in January 2012. The adoption of this accounting standard update did not have an impact on our financial position, results of operations, cash flows, or comprehensive income as it is intended to potentially simplify the assessment for goodwill impairment.
Reclassification	Reclassification Certain reclassifications have been made to prior periods to conform to the present year presentation. Specifically, for the quarter ended April 3, 2011 we have reclassified certain costs that were in cost of service revenues to cost of product revenues in the amount of $0.8 million. This reclassification has no impact on previously reported earnings from operations or net income.
