Latest Patents

One of McMains' latest inventions is a low-cost, highly-responsive temperature sensor. This sensor features a thermistor element that is surface-mounted in a circuit defined by an electrically-conducting layer of a three-layer circuit substrate. The design ensures close thermal coupling to a metal base layer on the opposite side of the substrate, which is adapted to monitor the temperature of a surface. The intermediate layer of the substrate contains a binder that electrically insulates the thermistor from the metal base layer while incorporating thermally-conducting particles to enhance thermal coupling.

Another significant patent is for a low-pressure sensor. This invention utilizes differentially connected capacitive sensors, with one sensor's flexible capacitor plate coupled to the pressure source and the other to ambient pressure. The design minimizes inaccuracies by employing a housing with a tapered inner wall and an O-ring, which applies a radial load to the sensor. This innovative approach reduces fabrication costs by providing a one-piece cup housing, ensuring that the electronics are securely mounted and sealed.
