Contingencies [Abstract]
Contingencies	6.Contingencies We may, from time to time, be subject to litigation and other claims in the ordinary course of our business. We accrue for estimated losses arising from such litigation or claims if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. To estimate whether a loss contingency should be accrued by a charge to income, we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of the loss. Since the outcome of litigation and claims is subject to significant uncertainty, changes in the factors used in our evaluation could materially impact our financial position or results of operations. We are currently unaware of any significant pending litigation affecting us other than the matters set forth below. We are a party to a civil suit filed by 3CEMS, a Cayman Islands and People’s Republic of China corporation, in the U.S. District Court for the Eastern District of Michigan and served on us on or about January 7, 2015. The suit alleges that we breached our contractual obligations by failing to pay for component parts to be used to manufacture optical video scopes for our discontinued Commercial Products Business Unit. 3CEMS alleged that it purchased the component parts in advance of the receipt of orders based upon instructions they claimed to have received from us. The suit alleged damages of not less than $4.0 million. We intend to vigorously defend against 3CEMS’ claims. Because of the inherent uncertainty of litigation and claims such as the 3CEMS matter, we are unable to reasonably estimate a possible loss or range of loss relating to the 3CEMS matter. As part of routine evaluation procedures, we identified a potential concern regarding the employment status and withholding for several individuals in one of our foreign jurisdictions. During fiscal 2015, we estimated a range of the potential financial liability related to this matter of €486,000 to €1 million. We were not able to reasonably estimate the amount within this range that we would be required to pay for this matter. As a result, in fiscal 2015, we recorded a reserve of €486,000 (equivalent to approximately $539,000) representing the minimum amount we estimated would be paid. In the fourth quarter of fiscal 2016, we received the final notice regarding this issue, and as a result, we recorded an additional expense of €227,000 (equivalent to approximately $250,000).
