Latest Patents
One of his latest inventions is a MEMS thermal flow sensor with compensation for fluid composition. This innovative device measures the flow rate of a fluid without requiring calibration for each specific fluid type. The sensor utilizes a response curve that is determined by plotting the sensor output voltage against the volume flow rate divided by the fluid's thermal diffusivity. This data is stored in memory, allowing for accurate flow rate measurements of unknown fluids by employing a conversion factor derived from the thermal time constants of both the calibration fluid and the measured fluid.
Another significant patent is the thermal mass flow sensor with improved sensitivity and response time. This sensor features a flow sensor tube with a heating element that heats the fluid as it flows through. It includes compact thermal sensors that measure the fluid temperature at both upstream and downstream ends of the heating element. Additionally, thermal grounding members are strategically placed to establish reference temperatures, enhancing the sensor's overall performance.
