Cost-method Investments, Description [Text Block]	Note 4 – Convertible Preferred Stock Investment On April 10, 2006 the Company invested $2,000,000 for a convertible preferred stock interest in Mevion Medical Systems, formerly Still River Systems, Inc., a development-stage company based in Littleton, Massachusetts, which in collaboration with scientists from MIT’s Plasma Science and Fusion Center, is developing a medical device for the treatment of cancer patients using proton beam radiation therapy. The Company also has deposits towards the purchase of three Mevion PBRT systems as described more fully in Note 3. The PBRT systems are not currently FDA approved. The Company’s initial investment in Mevion consisted of approximately 2,353,000 shares of Series B Convertible Preferred Stock. The Series B Convertible Preferred Stock is considered pari passu with previously issued Series A Convertible Preferred Stock. On September 5, 2007 the Company invested approximately $617,000 for an additional equity interest in Mevion. This investment represents approximately 588,000 shares of Series C Convertible Preferred Stock, which is considered pari passu with the previously issued Series A and Series B Convertible Preferred Stock (all issues together “Preferred Stock”). Since October 2008 Mevion has continued to offer a sequence of Series D rounds of funding to raise cash for its next phase of development and continued manufacture of the prototype model of the proton beam unit. Due to the troubled economy and scarcity of funds available during this time, these rounds were offered at a price less than the Company’s investment. Mevion has received approximately $65 million from these Series D rounds. In mid-2011, Mevion performed a reverse stock split of all shares in which 100 shares were converted to one share. The reason for the reverse stock split was to move the number of outstanding shares and price per share more in line with industry norms. The reverse stock split did not change any investor’s relative ownership in Mevion. In January 2012, Mevion announced that it had closed a $45 million Series E round of financing which will be used to accelerate the manufacturing and worldwide deployment of the Mevion S250. This round of financing was offered at a price per share higher than the effective price of the most recent Series D financing, and initially funded at 55%, with the remaining 45% due upon Mevion’s receipt of final FDA 510(k) clearance. The Company committed to invest an additional $70,000 in this round. The Preferred Stock is convertible at any time at the option of the holder into shares of common stock of Mevion at a conversion price, subject to certain adjustments, but initially set at the original purchase price. The Preferred Stock has voting rights equivalent to the number of common stock shares into which it is convertible, and holders of the Preferred Stock, subject to certain exceptions, have a pro-rata right to participate in subsequent stock offerings. In the event of liquidation, dissolution, or winding up of Mevion, the Preferred Stock holders have preference to the holders of common stock, and any other class or series of stock that is junior to the Preferred Stock. Upon conversion of the Preferred Stock, the Company’s investment represents an approximate 1.0% interest in the common stock of Mevion as of December 31, 2011. The Company does not have a Board of Directors seat with Mevion. The Company accounts for its investment in Mevion under the cost method and evaluates the investment for impairment on a quarterly basis or as events or circumstances might indicate that the carrying value of the investment may not be recoverable. The Company reviewed its investment in Mevion at December 31, 2011 in light of both current market conditions and the ongoing needs of Mevion to raise cash to continue its development of the first compact, single room PBRT system. The lower price per share of the Series D and Series E offerings could be viewed as a reasonable estimate of the fair value of our cost-method investment, indicating that our investment is impaired. The Company estimates that there is currently an unrealized loss (impairment) of approximately $1.3 million based on the issuance of the Series E funding compared to the Company’s cost of its investment. .In assessing whether the impairment is other than temporary, we evaluated the length of time and extent to which market value has been below cost, the financial condition and near term prospects of Mevion and our ability and intent to retain our investment for a period sufficient to allow for an anticipated recovery in the market value. Although the investment is not without certain risk, and the manufacture of the first unit has taken longer than originally anticipated, the Company believes that the current market value is a temporary situation brought on solely due to the continuing downturn of the economy, and is not a reflection on the progress or viability of Mevion or its PBRT design, and believes that our investment in Mevion is only temporarily impaired

Note 4 – Convertible Preferred Stock Investment

On April 10, 2006 the Company invested $2,000,000 for a convertible preferred stock interest in Mevion Medical Systems, formerly Still River Systems, Inc., a development-stage company based in Littleton, Massachusetts, which in collaboration with scientists from MIT’s Plasma Science and Fusion Center, is developing a medical device for the treatment of cancer patients using proton beam radiation therapy.

- Definition

The entire disclosure for investments accounted for under the cost-method. The carrying amount of such investments may be adjusted, for example, distributions in excess of cost (return of capital) or for other-than-temporary impairments. The cost method and lower-of-cost or market, an adaptation of the cost method, is generally followed for most investments in noncontrolled corporations, in some corporate joint ventures, and to a lesser extent in unconsolidated subsidiaries in which the entity does not have the ability to exercise significant influence.
