TRUE GAUGE PRESSURE TRANSDUCER WITH ANTI-ICING FEATURES
A gauge pressure transducer assembly having anti-icing features to allow for easy drainage of fluids to prevent pooling and icing. The assembly can include a header having one or more atmospheric ports extending therethrough, a differential sensing element mounted to the header, a header cap attached to at least a portion of the header, a gauge adapter attached to the header and in communication with the one or more atmospheric ports of the header, an elongated tube attached to the header cap, and a front port attached to the elongated tube. The gauge adapter includes a plurality of through-holes to facilitate drainage and de-icing. In some implementations, the header and the gauge adapter are disposed at the backside of the gauge pressure transducer assembly to reduce or eliminate regions where water can pool and freeze.
Measurement device for vehicle seat
A measurement device for a vehicle seat includes a memory; a processor coupled to the memory; a headrest body of a headrest; a first side section of the headrest that is swingable toward a seat front side so as to support the neck of the vehicle occupant; a second side section of the headrest that is swingable toward the seat front side so as to support the neck of the vehicle occupant; a first electrode provided at the first side section and contacting the neck in a state in which the first side section is supporting the neck; and a second electrode provided at the second side section and contacting the neck in a state in which the second side section is supporting the neck. The processor is configured to acquire a waveform of a potential difference based on the potential difference between the first electrode and the second electrode over time.
