LIQUIDITY [Abstract]
LIQUIDITY	NOTE C - LIQUIDITY During the last several years, the Company has incurred operating losses. We have sought to achieve profitability by launching the VasoHealthcare business, and by expanding our U.S. market product portfolio to include ambulatory monitoring devices (the BIOX series ECG Holter recorders, ambulatory blood pressure monitors and analysis software) and patient management devices (the EZ ECG and EZ O2 products). In fiscal 2011, the Company issued Series E convertible preferred stock (see Note N) to finance the initial operation of its Sales Representation segment and ultimately generated in excess of $4.1 million in operating cash flow by fiscal year end. While we expect to continue to generate significant operating cash flows in fiscal 2012, the progressive nature of the GEHC Agreement can cause related cash inflows to vary widely during the fiscal year. In addition, under the terms of our agreement with GEHC, we are entitled to commissions on certain undelivered sales orders received by GEHC prior to our agreement and transferred to us from GEHC as of September 30, 2010. These transferred orders, though subject to various risks including potential cancellation and changes in credit worthiness and availability, as well as the Company's continued compliance under the GEHC Agreement, generated commission revenue of $3.3 million from October 2010 to November 2011, and $1.0 million for the six months ended November 30, 2011, and are expected to generate additional commission revenues estimated to range from $1.3 million to $1.5 million over approximately one or more years. Based on our current operations through November 30, 2011, we believe internally generated funds from our Equipment and Sales Representation segments will be sufficient for the Company to continue operations through at least December 1, 2012.

NOTE C - LIQUIDITY

During the last several years, the Company has incurred operating losses. We have sought to achieve profitability by launching the VasoHealthcare business, and by expanding our U.S. market product portfolio to include ambulatory monitoring devices (the BIOX series ECG Holter recorders, ambulatory blood pressure monitors and analysis software) and patient management devices (the EZ ECG and EZ O2 products).

In fiscal 2011, the Company issued Series E convertible preferred stock (see Note N) to finance the initial operation of its Sales Representation segment and ultimately generated in excess of $4.1 million in operating cash flow by fiscal year end. While we expect to continue to generate significant operating cash flows in fiscal 2012, the progressive nature of the GEHC Agreement can cause related cash inflows to vary widely during the fiscal year.

In addition, under the terms of our agreement with GEHC, we are entitled to commissions on certain undelivered sales orders received by GEHC prior to our agreement and transferred to us from GEHC as of September 30, 2010. These transferred orders, though subject to various risks including potential cancellation and changes in credit worthiness and availability, as well as the Company's continued compliance under the GEHC Agreement, generated commission revenue of $3.3 million from October 2010 to November 2011, and $1.0 million for the six months ended November 30, 2011, and are expected to generate additional commission revenues estimated to range from $1.3 million to $1.5 million over approximately one or more years.

Based on our current operations through November 30, 2011, we believe internally generated funds from our Equipment and Sales Representation segments will be sufficient for the Company to continue operations through at least December 1, 2012.
