Employee Benefits [Abstract]
Employee Benefits	Note 8 Employee Benefits The Company sponsors a Section 401(k) plan (the "Plan") covering substantially all its eligible U.S. employees. The Plan entitles eligible employees to make contributions to the Plan after meeting certain eligibility requirements. Contributions are limited to the maximum contribution allowances permitted under the Internal Revenue Code. The Company matches 50% of the employee contributions up to a maximum of $3 as set forth in the Plan. The Company may also make discretionary contributions to the Plan, which would be allocable to participants in accordance with the Plan. For the years ended December 31, 2011, 2010 and 2009, the Company expensed $241, $224 and $187, respectively, for matching contributions to the Plan. The Company also sponsors a Section 401(k) plan covering eligible employees of Quickparts (the "Quickparts Plan"), which was acquired in early 2011. The Quickparts Plan entitles eligible employees to make contributions to the Quickparts Plan after meeting certain eligibility requirements. Contributions are limited to the maximum contribution allowances permitted under the Internal Revenue Code. The Company does not match the employee contributions; therefore, the Company had no expense for matching contributions to the Quickparts Plan.
