Note 2 - Discontinued operations
 
During 2013, the Company sold its RF Neulink and RadioMobile divisions, which together had comprised the Company’s RF Wireless segment. The divisions were sold pursuant to asset purchase agreements, whereby no purchase price was paid at the closing. Rather, the agreements stipulated royalty payments from each of the purchasers over a three year period. For the three and six months ended April 30, 2014, the Company recognized approximately $9,000 and $14,000, respectively, of royalty income related to the RF Neulink Agreement, which amounts have been included within discontinued operations. For the three and six months ended April 30, 2014, the Company recognized approximately $30,000 and $33,000, respectively, of royalty income related to the RadioMobile Agreement, which amounts have been included within discontinued operations.
