Legal Matters [Abstract]
Legal Matters	11. Legal Matters As previously reported by the Company, including in its Annual Report on Form 10-K for the fiscal year ended October 1, 2011 (the "2011 Form 10-K"), in January 2011, the U.S. Department of Commerce ("DOC") and the U.S. Attorney's Office for the District of Minnesota ("USAO") began an investigation into the Company's past disclosures on the U.S. Government's Online Representations and Certifications Application ("ORCA Certification") and later expanded the scope of inquiry to include the Company's government contracting compliance policies and general compliance record and practices in areas including export controls and government contracts. During the third quarter of fiscal 2012, the Company began negotiations for settlement of the matter. On July 27, 2012, the Company reached an agreement in principle with the USAO, subject to the approval of the Department of Justice ("DOJ"), settling, for $7.8 million, the DOC and USAO's investigation described above. If approved, the agreement would conclude the DOC and USAO investigation. In connection with the agreement in principle, the Company accrued a loss contingency equal to the settlement amount. The settlement is not final until approved by DOJ and until the Company and the USAO have signed the written settlement agreement. The Company expects the agreement in principle to be approved but there is no assurance that it will be and DOJ may reject it. If that were to occur, the Company will no longer have an agreement in principle and the DOC and USAO investigation would continue. In that event, the Company's loss could exceed its accrual and the Company would be unable to determine the ultimate amount of any fines or penalties or additional costs, or predict with certainty the timeline for the resolution of the investigation. The Company's known external legal and consulting costs related to the investigation in the first nine months of fiscal 2012 and 2011 totaled $0.4 million and $4.0 million, respectively. The $7.8 million accrual is non-deductible for income tax purposes.
