Research and Development [Abstract]
Research, Development, and Computer Software Disclosure [Text Block]	Research and Development Expenditures for research and development are charged to expense as incurred. Such expenditures amount to $4,972 and $5,389 for the three months ended May 31, 2015 and 2014, respectively, net of customer reimbursement, and are included within Engineering and Technical Support Expenses on the Consolidated Statements of Operations and Comprehensive Income (Loss). The Company enters into development and long-term supply agreements with certain of its OEM ("Original Equipment Manufacturer") customers. Revenues earned from the development services are recorded based upon the milestone method of revenue recognition provided certain criteria are met. Amounts due from OEM customers for development services are reflected as a reduction of research and development expense because the performance of contract development services is not central to the Company's operations. For the three months ended May 31, 2015 and 2014, the Company recorded $1,781 and $2,211, respectively, of development service revenue as a reduction of research and development expense based upon the achievement of a milestone.

The entire disclosure for research, development, and computer software activities, including contracts and arrangements to be performed for others and with federal government. Includes costs incurred (1) in a planned search or critical investigation aimed at discovery of new knowledge with the hope that such knowledge will be useful in developing a new product or service, a new process or technique, or in bringing about a significant improvement to an existing product or process; or (2) to translate research findings or other knowledge into a plan or design for a new product or process or for a significant improvement to an existing product or process whether intended for sale or the entity's use, during the reporting period charged to research and development projects, including the costs of developing computer software up to the point in time of achieving technological feasibility and in-process research and development acquired in a business combination consummated during the period.
