CONCENTRATION OF CREDIT RISK [Abstract]  
CONCENTRATION OF CREDIT RISK
Financial instruments, which potentially subject the Company to credit risk, consist of cash, cash equivalents and accounts receivable.  The Company’s policy is to limit the amount of credit exposure to any one financial institution.  The Company places investments with financial institutions evaluated as being creditworthy, or investing in short-term money market funds which are exposed to minimal interest rate and credit risk.  Cash balances are maintained with several banks.  Certain operating accounts may exceed insured limits.

The Company sells its products to customers involved in a variety of industries including information technology, medical devices and diagnostic systems, industrial controls and instrumentation and retail systems.  While the Company does not require collateral from its customers, it does perform continuing credit evaluations of its customers’ financial condition.
