Title: The Innovative Contributions of Dawood Parker
Introduction
Dawood Parker is a notable inventor based in London, GB. He has made significant contributions to the field of sensor technology, holding a total of 8 patents. His work primarily focuses on methods and apparatuses for monitoring gases, particularly in medical applications.
Latest Patents
One of his latest patents is a method and apparatus for zero calibration of oxygen-sensing. This invention allows for the calibration of a polarographic oxygen sensor at zero oxygen concentration by creating an oxygen-free liquid environment at the sensor's active surface. This is achieved electrolytically by depleting a thin film of electrolyte of oxygen to zero concentration using an oxygen-reducing cathode and a complementary anode. The sensor is placed in close proximity to the electrodes, and the oxygen in the electrolyte is reduced while its concentration is measured by the sensor. A low steady-state signal from the sensor provides the zero oxygen concentration calibration point.
Another significant patent is an apparatus for monitoring the partial pressure of gases. This apparatus is designed to monitor the partial pressure of a gas in liquid flowing through a line, such as the PO₂ or PCO₂ tension in blood. It includes a connector adapted for insertion in the line, featuring a membrane that is permeable to the gas but impermeable to the liquid. A sensor, such as an electrochemical sensor, is located adjacent to the membrane and responds to gas passing through it from the liquid.
Career Highlights
Dawood Parker has worked with prominent companies in the medical technology sector, including G.D. Searle & Company and Novametrix Medical Systems, Inc. His experience in these organizations has contributed to his expertise in sensor technology and gas monitoring systems.
