Legal Settlement [Abstract]

Legal Settlement [Text Block]

In February 2011, we reached a litigation settlement against a law firm that formerly represented us in patent litigation matters, representing reimbursement of legal fees previously paid to the firm.  Under the terms of the settlement, we received $2.5 million, which is included as a credit in operating expenses on the Consolidated Statement of Income for the year ended December 31, 2011.
