Restructuring and Related Activities Disclosure [Text Block]	Restructuring On November 30, 2016, a business restructuring was announced to reduce costs and align production levels with current levels of demand in a manner that is consistent with the Company’s long-term strategic plan. The Company is reducing materials spend as well as implementing various cost control initiatives. The workforce was reduced at both the North American production facility in Torrington, Connecticut, as well as at corporate offices in Danbury and remote locations. A total of 96 positions, or approximately 17% of the global workforce, was impacted. The production rate has been reduced to twenty-five megawatts annually, from the prior rate of fifty megawatts annually, in order to position for delays in anticipated order flow. This production level is anticipated to be temporary and will be reevaluated as order flow dictates, with any future increases being undertaken from what is now a lower cost basis. A restructuring expense relating to eliminated positions of $1.3 million has been recorded for the three months ended January 31, 2017, which has been presented on a separate caption in the Consolidated Statement of Operations.
