  • Patent number: 11754646
    Abstract: The present disclosure provides magnetic sensor system that includes a magnetic sensor package comprising a magnetic single turn sensor and a magnetic multi-turn sensor, and a shield arrangement for shielding the magnetic sensor from stray magnetic fields. The shielding arrangement comprises a ferromagnetic tube that houses one or more magnets and connects to an end of rotating shaft, such that rotation of the shaft causes a corresponding rotation of the ferromagnetic tube and magnets. The magnetic sensor package is positioned on a surface of a PCB substrate, which is positioned in close proximity to the ferromagnetic tube and magnet arrangement. A shielding device is then arranged in close proximity to the magnetic sensor package, for example, on the opposite side of the PCB substrate or directly between the PCB substrate and the ferromagnetic tube, to provide additional shielding of any stray magnetic fields.

  • Patent number: 11719660
    Abstract: A solid state, carbon dioxide (CO2) sensor configured for sensitive detection of CO2 in both dry and moist conditions. The CO2 sensor utilizes a composite sensing material that detects CO2 in the range of 100 ppm to 10,000 ppm. The sensing material is composed of O-MWCNTs and a metal oxide functionalizing agent, such as iron oxide (Fe2O3) nanoparticles. The material has an inherent resistance and conductivity that is chemically modulated as the level of CO2 increases. The CO2 gas molecules that are absorbed into the carbon nanotube composites cause charge-transfer and changes in the conductive pathway causes changes in conductivity of the composite sensing material. This change in conductivity provides a specificity and sensitivity for CO2 detection. The CO2 sensor can be easily integrated into existing electronic circuitry and hardware configurations, including the hardware of a mobile computing device, such as a smart phone or tablet device.
