A recently granted patent (Publication Number: US11913848B2) discloses a sensor assembly designed to provide values of a physical property of a vehicle. The assembly includes electronic circuitry with a sensor to detect the physical property, a locking arrangement, and an exhaustible power source. Two switch means, controllable from outside the assembly, are arranged in parallel between the circuitry and the power source. The first switch can be controlled externally, while the second switch is activated by the locking arrangement, ensuring uninterrupted power supply to the circuitry once activated. The assembly's innovative design allows for efficient and reliable sensing of the vehicle's physical properties.

Furthermore, the patent details various configurations and components of the sensor assembly, including the use of a magnet-sensitive switch element, a mechanical switch element like a Reed switch, and a logical OR unit to control power supply. The assembly also features a FET transistor as the third switch element, ensuring a high resistance connection between the power source and the circuitry. Additionally, the sensor assembly can be used in gas pressure sensor units for vehicle tires, with options for wireless communication of measured values. The patent also covers a sensor shipment set with a unique packaging design incorporating a magnet to activate the assembly's switch means. Overall, the patent highlights a sophisticated sensor assembly tailored for accurate measurement and monitoring of a vehicle's physical properties, particularly gas pressure in aircraft tires, utilizing innovative switch control mechanisms and power management techniques.
