Mergers, Acquisitions and Dispositions Disclosures [Text Block]	9. Sale of development project On March 8, 2013, we entered into an Asset Purchase Agreement with a third party (the “Buyer”) to sell certain development projects (intellectual property) and long-lived assets (the “Connectivity Assets”) related to the connectivity technology over coaxial cable market, including the transfer of 21 employees (the “Connectivity Employees”) to the Buyer. The aggregate carrying amount of the Connectivity Assets ultimately transferred was approximately $0.6 million and were classified as assets held for sale in prepaid expenses and other current assets in the condensed consolidated balance sheet at February 2, 2013. We received an initial payment of $2.0 million in cash at the closing of the transaction and a payroll expense reimbursement payment of $0.6 million (as described more fully below). Under the terms of the Asset Purchase Agreement, if certain technical milestones were met by September 30, 2013 as a result of further development of the transferred technology by the Buyer, we were to be paid an additional $5.0 million in cash. In April 2013, upon receiving the closing consideration of $2.0 million, we recorded a gain of $1.1 million, net of the carrying value of the Connectivity Assets and fees for legal and bank services of approximately $0.4 million. The gain is included in “Gain on sale of development project” in the accompanying condensed consolidated statements of operations for the six months ended August 3, 2013. Additionally, in April 2013, in connection with the Asset Purchase Agreement, the Buyer reimbursed us for payroll expenses related to the employees transferred to the Buyer for the period from February 1, 2013 through the actual payroll transfer, totaling $0.6 million. As the contingent consideration was uncertain at the time of the initial sale, we did not recognize the contingent payment. Accordingly, payment consideration, if and when it is determined that the milestone was met, will be recorded as other income in our consolidated statements of operations in its entirety. The technical milestones were due by September 30, 2013. The Buyer advised us that it does not believe the milestones had been met by September 30, 2013. We are currently pursuing our rights through the dispute resolution provisions set forth in the Asset Purchase Agreement. To the extent we recognize any payment in regard to the milestone completion, we will recognize income upon receipt of any such proceeds from the Buyer. On September 5, 2014, the Buyer filed counterclaims in response to our claims arising from the Asset Purchase Agreement. We intend to contest these counterclaims vigorously and believe they are without merit.
