  • Patent number: 12360181
    Abstract: A sensor, comprising: a magnetic field sensing module that is configured to generate a plurality of signals, each signal indicating a magnetic flux density of a different component of a magnetic field that is produced by a magnetic field source; a processing circuitry that is configured to: receive the plurality of signals from the magnetic field sensing module; evaluate a neural network based on the plurality of signals to obtain a plurality of probabilities, each of the plurality of probabilities indicating a likelihood of the magnetic field source being positioned in a different one of a plurality of positional domains; generate an output signal based on the plurality of probabilities, the output signal encoding an identifier of a current positional domain of the magnetic field source.

  • Patent number: 12117291
    Abstract: A method for use in a sensor, comprising: generating a signal that is indicative of an angular position of a rotating target, the signal being generated by at least one magnetic field sensing element; adjusting the signal to produce an adjusted signal, the signal being adjusted based on a current value of a first adjustment coefficient and a current value of a second adjustment coefficient, the first adjustment coefficient including a gain adjustment coefficient, and the second adjustment coefficient including an offset adjustment coefficient; generating an output signal based on the adjusted signal; and updating the first adjustment coefficient, the updating including replacing the current value of the first adjustment coefficient with a new value of the first adjustment coefficient, the updating being performed by minimizing a function that is based on the current value of the first adjustment coefficient and the current value of the second adjustment coefficient.

  • Patent number: 11163021
    Abstract: Methods and apparatus for combining redundant signals to generate outputs signals with enhanced accuracy and/or risk level. In embodiments, first signals are generated by a first transducer and second signals are generated by a second transducer. In other embodiments, first signals are generated by a first die and second signals are generated by a second die. An amount of overlap between error distributions of the first and second signals can be used to detect failure and/or indicate risk of failure.

  • Patent number: 10368707
    Abstract: A vacuum cleaner tube assembly includes an outer tube defining a vacuum passage extending from a first end to a second end and an inner tube disposed at least partially within the vacuum passage and connected to the outer tube for telescopic adjustment. The inner tube includes a first end and a second end distal from the first end. The vacuum tube assembly further includes an adjustment clamp connected to the second end of the outer tube. The adjustment clamp includes a clamp body with an inner diameter connected to the second end of the outer tube. The adjustment clamp also includes a lever connected to the clamp body and moveable between a first, latched position and a second, unlatched position to permit selective adjustment of the inner diameter of the clamp body and selective clamping between the clamp body and the inner tube.
