  • INERTIAL NAVIGATION SYSTEM CAPABLE OF DEAD RECKONING IN VEHICLES
    Publication number: 20230358541
    Abstract: A device including microelectromechanical systems (MEMS) sensors are used in dead reckoning in conditions where Global Positioning System (GPS) signals or Global Navigation Satellite System (GNSS) signals are lost. The device is capable of tracking the location of the device after the GPS/GNSS signals are lost by using MEMS sensors such as accelerometers and gyroscopes. By calculating a misalignment angle between a forward axis of a sensor frame of the device and a forward axis of a vehicle frame using the data received from the MEMS sensors, the device can accurately calculate the location of a user or the vehicle of the device even without the GPS/GNSS signals. Accordingly, a device capable of tracking the location of the user riding in the vehicle in GPS/GNSS signals absent environment can be provided.

  • Adaptive test method and designs for low power mox sensor
    Patent number: 11808723
    Abstract: The present disclosure is directed to a gas sensor device that includes a plurality of gas sensors. Each of the gas sensors includes a semiconductor metal oxide (SMO) film, a heater, and a temperature sensor. Each of the SMO films is designed to be sensitive to a different gas concentration range. As a result, the gas sensor device is able to obtain accurate readings for a wide range of gas concentration levels.
