US SEISMIC SYSTEMS, INC. [Abstract]
Increase of Investments in Subsidiary Disclosure [Text Block]	US SEISMIC SYSTEMS, INC. On February 6, 2012, the Company entered into a new Stock Purchase Agreement (the “USSI Purchase Agreement”) with USSI pursuant to which the Company converted previously advanced funds into additional shares of USSI common stock (“USSI Common Stock”) and shares of USSI's new Series A-1 Preferred Stock (“USSI Preferred Stock”). The Company also made a further payment to USSI of $2,250 on February 6, 2012 to purchase additional shares of USSI Preferred Stock. The USSI Preferred Stock provides that upon any future liquidation of USSI, to the extent funds are available for distribution to USSI's stockholders after the satisfaction of any USSI liabilities at that time, USSI would first repay the Company for the purchase price of its USSI Preferred Stock. Thereafter, the Company would receive a further payment for such shares ratably with all other USSI Common Stock holders as though the Company's shares of USSI Preferred Stock were the same number of shares of USSI Common Stock. In April 2012, the Company conducted a second closing for the purchase of additional USSI Preferred Stock in accordance with the USSI Purchase Agreement and invested an additional $2,500 in USSI. Following this investment, the Company would own approximately 92% of USSI upon conversion of the USSI Preferred Stock. On July 30, 2012, the Company entered into another Stock Purchase Agreement (the “Summer USSI Purchase Agreement”) with USSI pursuant to which the Company made a payment to USSI of $2,500 to purchase additional shares of USSI Preferred Stock. The USSI Preferred Stock is the same class of shares that the Company acquired earlier this year (see above). In connection with this investment, the Company also entered into a Second Amended and Restated Stockholders Agreement with USSI and its other stockholders providing for certain rights and obligations to purchase or sell our USSI securities and with regard to the management of USSI. Following the July 30, 2012 payment to USSI, the Company would own approximately 93.6% of USSI upon conversion of the USSI Preferred Stock. The Summer USSI Purchase Agreement contemplated that the Company would make an additional investment of $2,500 later in 2012 in exchange for additional shares of USSI Preferred Stock. On November 1, 2012, the Company made this additional investment (see Subsequent Events - Note 12). In connection with the USSI Purchase Agreement, the Company established a new 2012 Stock Plan (the “USSI 2012 Stock Option Plan” or the "Plan") under which key employees, directors and consultants of USSI may receive options to purchase up to an aggregate of 1,180,000 shares of USSI Common Stock on such terms as the Plan provides and as determined by USSI's board of directors or by such committee designated by USSI's board to administer the Plan, if any. If options to purchase all shares of USSI Common Stock available under the Plan are granted and exercised, the Company would own approximately 83.2% of USSI upon conversion of the USSI Preferred Stock. See Note 8(d).
