"After launching a GPS bracelet for Alzheimer's-related straying and earlier this week, unveiling the Urgentys mobile GPS alarm button, the notice from the United States Patent and Trademark Office is great news for our team, as it continues to develop the system", stated VPS inventors Louis Massicotte, President and CEO of Medical Intelligence Technologies, and Jean-François Montplaisir, the company's Vice-President of Technologies.
"Since we introduced our portable cardiac alarm system at a major conference on interventional cardiology three years ago, it has attracted growing interest throughout the world. The issuance by the United States Patent and Trademark Office is timely because, as we have envisioned in our strategic plan, we expect to begin marketing the VPS in 2008. Soon, survivors of cardiac arrest will be able to wear our VPS belt, which is designed to detect cardiac anomalies and automatically notify a central monitoring station with the patient's GPS co-ordinates."
Specifically, a slow adaptive personalized model of the patient's electrocardiogram is built using signals from the patient over a certain period of time. A current monitoring signal for the patient is then obtained, and specific base points of the signal are compared to corresponding points in the model. The comparison is done using threshold values for both the horizontal and vertical values of the base points. The base points are eliminated if they are within the thresholds but improbable in the model. Trends related to cardiac conditions can then be identified in the remaining base points.
Medical Intelligence is specialized in the personal medical tele-security industry, integrating information and telecommunications technologies to the health care sector. The firm designs portable medical devices equipped with an automatic alarm system for the benefit of people suffering from cognitive disorders or cardiovascular diseases. The Québec, Canada-based company also has an office in Paris. Its French affiliate, Medical Mobile, is the first such company to provide medical "telecom" service, personal and mobile "telemedicine".
