  • Patent number: 11312621
    Abstract: The performance of a microelectromechanical systems (MEMS) device may be subject to unwanted thermal gradients or nonuniform temperatures. The thermal gradients may be approximated based on voltage measurements taken through bond wires coupled to bond points located on the MEMS device. Thermal gradient measurement may be improved depending on the arrangement of bond wires and/or the material of the bond wires. Sense circuitry that is coupled to the MEMS device may determine corrective actions, such as updating the operation of the MEMS device, that compensate for the adverse effects from the thermal gradients.

  • Patent number: 11300583
    Abstract: Anemometer for independently measuring wind speed and direction in fluid medium. A second anemometer portion has at least one attribute resulting in different wind resistance in fluid medium than a first anemometer portion, such as a different: mass, shape, density, specific gravity, drag coefficient and/or freedom of motion. Different wind resistance causes inclination of anemometer when deployed to fall autonomously along a trajectory of fluid medium, where anemometer drag coefficient curtails initial ballistic trajectory such that anemometer enters free-fall descent after deployment. Anemometer includes inclinometer to obtain inclination measurements, and memory/transmitter to store/transmit inclination measurements. Local wind direction/speed is determined from inclination measurements based on direction/degree of anemometer inclination in correlation with measurement timings. Anemometer may be deployed from moving airborne platform.

  • Patent number: 11293795
    Abstract: A personal flow meter for measuring water consumption of an individual has a housing, inductors attached to the exterior of the housing and a rotatable member disposed within the housing. A front cover and rear cover are attached to the housing. The front cover includes a fluid inlet having an angulated internal fluid channel that causes water to enter the housing at an angle. The rear cover has a fluid outlet to allow egress of water within the housing. The rotatable member includes angulated fins. Water entering the housing via the internal fluid channel perpendicularly strikes the fins to initiate rotation of the rotatable member. Magnets are attached to the rotatable member in an alternating magnetic pole arrangement. Rotation of the rotatable member causes the inductors to generate voltage signals. Electronic circuitry processes the voltage signals and generates signals that represents the individual's water consumption over a period of time.

  • Patent number: 11287442
    Abstract: An in-situ test calibration system and method are disclosed where a perpetual out-of-band electrostatic force induced excitation is used to dither the proof-mass of a MEMS based accelerometer where the amount of deflection change is proportional to sensitivity changes. The supplier of the accelerometer would exercise the accelerometer in a calibration station to determine initial sensitivity values. After the calibration and before removing the accelerometer from the calibration station, the supplier would start the dither and calibrate the acceleration equivalent force (FG) to drive voltage transfer function (FG/V). After installation of the accelerometer into a system or sometime later in the field, any changes in the FG/V transfer function due to changes in the sensitivity are observable and can be used for re-calibrating the accelerometer.
