Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes In the third quarter of 2011 and 2010, the Company recorded an income tax expense of $10,000 and income tax benefit of $192,000, respectively. The income tax expense and benefit were primarily from our foreign operations which are cost-plus entities. Included within the benefit from income taxes for the third quarter of 2010 was an out of period adjustment relating to an intraperiod tax allocation which resulted from the unrealized gains on our investment in TowerJazz. Based on the available objective evidence, management believes it is more likely than not that the net deferred tax assets will not be fully realizable. Accordingly, with the exception of its foreign subsidiaries, the Company has provided a full valuation allowance against the associated deferred tax assets. The Company will continue to assess the realizability of the deferred tax assets in future periods. The Company had approximately $76,000 and $73,000 of unrecognized tax benefits at October 2, 2011 and January 2, 2011, respectively. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. As of October 2, 2011, the Company had approximately $23,000 of accrued interest and penalties related to uncertain tax positions. The Company is no longer subject to U.S. federal, state and non-U.S. income tax audits by taxing authorities for fiscal years through 1992.
