Income Taxes [Abstract]
Income Taxes	NOTE 13: INCOME TAXES At October 28, 2011, we had a $12,948 liability recorded for gross unrecognized tax benefits (excluding interest and penalties). Of this total, $12,203 represents the amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. As of October 28, 2011, we had accrued approximately $4,620 of interest and penalties relating to unrecognized tax benefits. During the first quarter of fiscal year 2012, we recorded a $3,600 benefit to income tax expense related to an increase in the tax basis of assets for a foreign subsidiary. In the same period of fiscal year 2011, we recorded a $1,250 benefit to income tax expense for the retroactive extension of the U.S. federal research and development tax credit.
