摘要： A spray system includes nozzles spaced along a distribution line. Each nozzle actuates the position of one or more internal valves based on a spray command received from a system control module. Sensors generate position information regarding the actuation of the valves. The actual valve positions are compared to expected valve positions to determine a deviation between the two. The deviation can be compared to a threshold to determine a status of that nozzle. A normal nozzle status can be generated based on the deviation being less than the threshold. An abnormal nozzle status can be generated based on the deviation being equal to or exceeding the threshold.

摘要： A metal tube (10) constituting a fluid flow path (12) is cut, and an attachment (14A) for a fluid characteristic measurement sensor is interposed between end portions of the cut metal tubes (10). The attachment (14A) includes a body (16A) through which a body flow path (1606) extends through and to which a temperature sensor (18) and a pressure sensor (20) are attached in advance and a pair of connection members (22) that connect a fluid flow path (12) and the body flow path (1606). Joint fittings (24A) are allowed to be used as a pair of connection members (22). The attachment improves workability 10 when measuring a characteristic of a fluid and reliably reducing a leakage of the fluid.

摘要： A flow-through pressure transducer comprising a cylindrical diaphragm positionable to allow fluid to flow therethrough which responds to variations in fluid pressure to generate an electrical signal proportional to such variations and which is incorporated in a housing for interconnecting with fluid delivery tubing. The diaphragm is made of relatively thin resilient metal, shaped to be a tube, elliptical in cross-section, with transducers, located on the elliptical major and minor axes which change their electrical state in response to movement of the diaphragm walls, and which are coupled in a bridge circuit for signal measurement. The housing is constructed for either gage or absolute fluid pressure measurements.

摘要： Systems and methods are disclosed herein for estimating tread depth remaining on a tire mounted on a vehicle. One or more sensors are provided for detecting operational data associated with the vehicle and tire measurements corresponding to ambient temperature and contained air temperature, which may be directly measured or derived from measured tire pressure. A thermal mass of the tire is estimated based on at least the detected operational data and tire conditions, and a current tread depth of the tire is estimated based at least in part on the respective estimated thermal mass. In certain embodiments, the thermal mass estimation may be performed using heat transfer models limited to measurements captured during a cooling down phase of the tire while the vehicle is not moving, thereby simplifying calculation of a corresponding time constant.

摘要： A method for estimating the pressure measurement bias of a barometric sensor in a wireless terminal. A location engine using the method generates an enhanced estimate of the measurement bias. The location engine generates the enhanced estimate based in part on Global Navigation Satellite System (GNSS)-based estimates of the elevation of the wireless terminal, which the terminal generates as it concurrently makes barometric pressure measurements. Each GNSS-based estimate of elevation is often generated from noisy measurements and has an associated uncertainty. The location engine accounts for the uncertainty in the GNSS estimates of elevation by applying an optimal estimation technique, such as Kalman filtering, on the biased pressure measurements and the GNSS-based estimates. Once the location engine generates the enhanced estimate of measurement bias, it can adjust subsequent measurements of barometric pressure made by the wireless terminal and generate improved estimates of elevation of the wireless terminal.

摘要： An interface pressure sensor includes a fluid pressure sensor disposed in a volume defined by a shear wall. The volume is enclosed, and the fluid pressure sensor is encapsulated by, an infill material. The infill material defines a sensing surface that, when pressed, can impart a force that is detectable by the fluid pressure sensor. The interface pressure sensor can be used for applanation tonometry.
