  • Patent number: 11611140
    Abstract: A liquid level sensor system can include a container configured to hold a volume of a liquid and a monopole antenna arranged proximate the volume of the liquid. A radiofrequency circuit may be configured to apply a radio frequency signal to the monopole antenna and provide one or more signals indicative of a level of the volume of the liquid within the container based on a radio frequency characteristic of the monopole antenna.

  • Publication number: 20210354683
    Abstract: A system for sensing a position of a first member relative to a second member based on a radio frequency characteristic of a bias member is disclosed. The bias member may be configured to bias the second member relative to the first member. Radio frequency circuitry may be configured to apply a radio frequency signal to the bias member and provide one or more signals indicative of a position of the first member relative to the second member based on a radio frequency characteristic of the bias member.

  • Patent number: 11068013
    Abstract: An electronic pedal assembly may include a pedal platform and at least one force sensor configured to sense a force applied to the pedal platform. One or more control devices may be communicatively coupled to the force sensor(s) and configured to determine a throttle output for controlling the throttle condition of the vehicle based at least in part on the force applied to the pedal platform and based at least in part on an operating condition associated with operating the vehicle. In some embodiments, the force sensor(s) may be configured to measure a force distribution on the pedal platform. The control device(s) may monitor the force distribution and adjust an operation of the vehicle based on the force distribution. The operation of the vehicle can include controlling the throttle condition of the vehicle or an operation that is different from controlling the throttle condition of the vehicle.

  • Publication number: 20090217774
    Abstract: There is described an apparatus for providing rotary displacement information indicative of the torque applied to a torsion bar which is rotatable relative to a housing, in which the electromagnetic coupling between a transmit aerial fixed relative to the housing and a receive aerial fixed relative to the housing varies in dependence upon first and second resonators fixed to the torsion bar at spaced axial positions. The first and second resonators have respective different resonant frequencies to enable the signal coupled between the transmit aerial and the receive aerial via the first resonator to be distinguished from the signal coupled between the transmit aerial and the receive aerial via the second resonator.

  • Publication number: 20080116883
    Abstract: In an inductive sensor device, and a method for inductive identification, a first and a second exciter inductor 16a, 16b extend along a measurement range and vary spatially differently from each other. A first and a second inductive coupling element 12a, 12b couple a signal from the exciter inductors 16a, 16b into a receiver inductor 18. The inductive coupling elements 12a, 12b are formed as resonance elements with a first resonance frequency f1 and a second resonance frequency f2. In order to be able to simply determine the position of both inductive coupling elements quickly and accurately, the two exciter inductors are driven by different transmission signals S1, S2. Each of the transmission signals includes signal components of a first carrier frequency near the first resonance frequency f1 varying in temporal progression, and of a second carrier frequency near the second resonance frequency f2 varying in temporal progression.

  • Publication number: 20060144166
    Abstract: In an inductive torque sensor, two rotatable rotor elements (114a, 114b) are mounted axially and adjacent at a distance from the shaft components (112a, 112b) of a shaft (112). An inductive coupling element (18) is mounted about the circumference of each of the rotor elements (114a, 114b). An inductive circuit (30) with at least two inductors (34a, 34b, 34) on a stator element (120) extends along a sensor area so that, when the rotor elements (114a, 114b) rotate, the inductive coupling elements (18) are displaced along the inductors (34, 34a, 34b), causing a position-dependent inductive coupling between the inductors. Cost-effective manufacture is possible if the inductive circuit (30) is so mounted that with the inductive coupling element (18) it covers both rotor elements (114a, 114b). The inductive coupling elements (18) thus possess distinguishable inductive coupling characteristics.
