Debt Disclosure [Abstract]
Credit Facility	CREDIT FACILITY On December 5, 2011, the Company entered into a five-year senior secured credit facility in the aggregate principal amount of $35.0 million. The availability under the credit facility is limited to a borrowing base, subject to meeting certain conditions set forth in the credit facility. The credit facility includes a feature that allows the Company to increase the revolver amount in the first 18 months. The Company exercised this feature, and on May 1, 2012, the revolver amount was increased by $5.0 million to an aggregate principal amount of $40.0 million. On February 25, 2013, the Company amended the agreement and reduced the revolver amount by $15.0 million from an aggregate principal amount of $40.0 million to $25.0 million. The credit facility includes a $10.0 million letter of credit subfacility. See Note 20 "Commitments and Contingencies" for more information regarding the letter of credit. The availability of the aggregate principal amount under the credit facility will fluctuate, generally monthly, based on eligible domestic accounts receivable and inventory due to a variety of factors including the Company's overall mix of sales and resulting accounts receivable with international and domestic customers, United States governmental agencies and a few individual customer accounts which may result in high concentrations of accounts receivable as compared to the overall level of the Company's accounts receivable. The credit facility contains financial covenants including, under certain conditions, maintaining a minimum fixed charge coverage ratio, as well as other non-financial covenants, including restrictions on declaring and paying dividends, and is secured by substantially all of the Company's assets. The credit facility terminates on December 5, 2016. Borrowings under the credit facility bear interest based on a rate of the Company's choice equal to either: 1) the LIBOR plus a margin of 2.50 percent per annum or 2) the base rate plus a margin of 1.75 percent per annum. The base rate is the greater of (a) the Federal Funds rate plus 0.50 percent, (b) the LIBOR rate plus 1.00 percent or (c) the prime rate of the financial institution. The LIBOR rate and the base rate are determined at the specified date preceding or at the time of the borrowing in accordance with the terms of the credit facility. In addition, unused line fees are payable on the credit facility at rates of 0.40 percent per annum. In December 2012, the Company made a $15.7 million payment to pay off the outstanding balance on the credit facility, which included $0.4 million of accrued interest. Accordingly, as of March 29, 2013, the Company had no outstanding balance owed on the credit facility. As of March 29, 2013, the maximum amount available to be borrowed under the credit facility was approximately $23.0 million which takes into account a $2.0 million outstanding letter of credit to back the Company's obligation to pay for goods or services to a supplier. The Company was in compliance with all covenants as of March 29, 2013.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
