  • Patent number: 12013262
    Abstract: The present disclosure relates to a sensor assembly for simultaneously capturing an angular position and a torque of a rotatable shaft. The sensor assembly comprises, for determining the angular position, a main body, two additional bodies, which are arranged coupled for rotation on the main body, and two angle resolvers, which are arranged on a circuit board in the immediate vicinity of the additional bodies. In this arrangement, the angles of the additional bodies are determined by the angle resolvers and passed as an angle signal to an evaluation unit arranged on the circuit board. The sensor assembly further comprises a direct coating, which captures a torque signal from the rotating shaft and passes this signal over a connection line to the evaluation unit. The connection line has a section wound multiple times around the shaft to permit a rotation of the shaft by at least +/?900°.

  • Patent number: 12007432
    Abstract: Techniques for testing connectivity between a first integrated circuit (IC) and a second IC of an electronics package are described. An example technique involves controlling a switch(es) in the first IC to configure a bias direction of a photodiode of the second IC to forward biased. A connectivity test between the first and second ICs is performed, when the photodiode is forward biased. Another technique involves controlling a switch(es) in the first IC to configure a bias direction of a photodiode in the second IC to reverse biased. A first voltage is measured at an input of a transimpedance amplifier (TIA) in the first IC when the photodiode is reverse biased. The switch(es) are controlled to change the bias direction of the photodiode to forward biased. A second voltage is measured at the input of the TIA when the photodiode is forward biased.

  • Patent number: 11972916
    Abstract: A compact fall detection sensor includes a case. A magnet is housed in the case. A reed switch with a pair of reeds are integrally positioned around the central axis of the case at the bottom of the case. In an upright state, the magnet is gravitationally positioned in the longitudinal direction of the reed switch around the central axis of the curved surface of the case, each magnetic pole magnetizing the corresponding reed of the reed switch, allowing one of the reeds to be magnetized to N pole and the other reed to S pole to turn on the switch. When inclined from the upright state, the magnet slides along the curved surface of the case and deviates from the central axis, to position only one of the magnetic poles of the magnet around the central axis to turn off the reed switch.
