Income Tax Disclosure [Text Block]	Income Taxes: We are subject to federal income tax as well as income tax of multiple state and foreign jurisdictions. We are no longer subject to federal, state and local, or foreign income tax examinations for years before 2008, 2007 and 2005, respectively. We have federal net operating loss carryforwards that expire at various dates between 2023 and 2029. We have state net operating loss carryforwards that expire at various dates from 2012 through 2030. We also have federal and state credit carryforwards, some of which do not expire, with the remainder expiring at various dates from 2012 through 2031. During the fourth quarter of 2011, we concluded it was more likely than not that we would be able to realize the benefit of a portion of our remaining deferred tax assets. We based this conclusion on improved operating results over the past two years and our expectations about generating taxable income in the foreseeable future including the implementation of a global tax structure. We exercised significant judgment and considered estimates about our ability to generate revenues, gross profits, operating income and taxable income in future periods under our new tax structure in reaching this decision. As part of our global tax structure implementation, an intercompany sale of inventory and fixed assets occurred during the first quarter of 2012. The inventory portion of this intercompany sale is expected to be sold to end customers in the normal course of business. As the inventory sells to our end customers, taxes are applied to the gain based on U.S. statutory tax rates, primarily offset by deferred tax assets. This resulted in an increase to the effective tax rate and a net tax provision of $7.9 million in the first three months of fiscal 2012. A similar net tax provision amount is expected in the next quarter as the inventory is sold to end customers. We are not currently under examination in any tax jurisdictions. We believe that it is reasonably possible that $0.4 million of unrecognized tax benefits and $0.1 million of associated interest and penalties could significantly change during the next twelve months. The $0.5 million potential change would represent a decrease in unrecognized tax benefits, comprised of items related to federal research and development credits and uncertain income tax positions related to foreign tax filings for years that will no longer be subject to examination under expiring statutes of limitations. We are paying foreign income taxes, which are reflected in the provision for income taxes in our Condensed Consolidated Statements of Operations and Comprehensive (loss) income and are primarily related to the cost of operating an offshore research and development, marketing and sales subsidiaries. We are not currently paying federal income taxes and do not expect to pay such taxes until the benefits of our tax net operating losses are fully utilized. We expect to pay a nominal amount of state income tax. We accrue interest and penalties related to uncertain tax positions in the provision for income taxes.
