Earnings Per Share [Abstract]
Earnings (loss) per share	12.   Earnings (loss) per share For all periods, basic earnings (loss) per share (“EPS”) is calculated by dividing net earnings (loss) by the weighted-average common shares outstanding. Diluted EPS in profitable periods reflects the effect of all potentially dilutive common shares outstanding by dividing net earnings by the weighted-average of all common and potentially dilutive shares outstanding. Potentially dilutive stock options of 1,717,138 for the three and six months ended July 3, 2011 and 1,601,082 for the three and six months ended July 4, 2010, were not used to compute diluted earnings per share because the effects would have been anti-dilutive.
