When Sensing Means Life Or Death

Medical Sensors Help In Non-Invasive Ways

By Hank Russell

Approximately three years ago, Nexense (Tel Aviv, Israel) found a new way of performing physical measurements which the company belived was a massive improvement over the state-of-the-art sensors out in the market today. During the company’s 14 years in existence, it has received numerous joint ventures and applications from other companies in the automotive, security and medical markets.

About two months ago, the company was awarded U.S. Patent No. 6,621,278 (titled “High-Precision Measuring Method and Apparatus”) for its unique method of measuring predetermined parameters, such as temperature, acceleration, pressure, distance and other physical entities. The technology is based in internal propagation of a cyclically-repeating energy wave from a primary location, which is then received by a secondary location. It then detects a predetermined reference point in the energy wave and continuously changes the frequency of an exciter to the point where the number of waves equals an integer. By utilizing the change in frequency, a measurement of the predetermined parameter is produced.

Recently, the company has begun working on medical diagnostic sensors that would help save people’s lives. The first involves medical imaging of the cardiovascular system and the other involves sleeping patterns, both of which deliver real-time 3D tomography completely in a non-invasive manner.
