| Fair Value, Measurement Inputs, Disclosure [Text Block] | **12****.          **FAIR VALUE MEASUREMENTS    

Financial assets and liabilities at fair value at December 31, 2013 and 2012 are classified in one of the three categories, which are described below.
                   
●

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
                   
●

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
                   
●

Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers a counterparty credit risk in its assessment of fair value.

The carrying amount of cash and cash equivalents, accounts receivables and accounts payables and other short-term financial instruments approximate their fair value due to their short-term nature. Included in cash equivalents at December 31, 2013 are $3.9 million of investments in overnight repurchase agreements which are categorized as level 2 for fair value measurement. The Company believes that borrowings outstanding under its revolvers and its term loans approximate fair value because such borrowings bear interest at current variable market rates. The Company's borrowings are categorized as level 2 for fair value measurement. The contingent consideration, resulting from the Business Combination with Hego, has been adjusted to its fair value of $12.3 million at December 31, 2013, in the level 3 category. The contingent consideration was calculated using a probability based model measuring the likelihood      of achieving the revenue milestones, as defined in the Stock Purchase Agreement, and valued based on the market value of the Company's common stock. At December 31, 2013, the likelihood of achieving the revenue milestones was based on a probability level of 100% relating to the 2013 earn-out and 90% for the 2014 and 2015 earn-outs, respectively.    

Additionally, on a nonrecurring basis, the Company uses fair value measures when analyzing asset impairment. Long-lived assets and certain identifiable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If it is determined such indicators are present and the review indicates that the assets will not be fully recoverable, based on undiscounted estimated cash flows over the remaining amortization periods, their carrying values are reduced to estimated fair value. Measurements based on undiscounted cash flows are considered to be level 3 inputs. During the fourth quarter of each year, the Company evaluates goodwill and indefinite-lived intangibles for impairment at the reporting unit level including, but not limited to macro-economic conditions, market and industry conditions, internal cost factors,      competitive environment, share price fluctuation, results of past impairment tests and the operational stability and the overall performance of the reporting units. This measurement would be classified based on level 3 input.

The following table represents a reconciliation of items measured at fair value on a recurring basis using unobservable inputs (level 3) (in thousands):

Unrealized loss for the year - change in fairvalue of contingent consideration
