  • Patent number: 11974105
    Abstract: A noise canceling audio in/out device includes an audible in/out transducer operable to convert an audible noise signal to a noise signal and convert an audio transmit (TX) signal to an audible output signal. A transducer signal of the audible in/out transducer generated by the audio TX signal is affected by the noise signal. The noise canceling audio in/out device further includes a noise canceling circuit operable to convert a digital TX signal to a TX reference signal, compare the transducer signal with the TX reference signal to produce an analog comparison signal, where the analog comparison signal includes a representation of the audio TX signal and the noise signal, and regulate the transducer signal to substantially match the TX reference signal to remove the effect of the noise signal on the transducer signal.

  • Patent number: 11949244
    Abstract: A device operative to transfer power wirelessly includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s). The DSC generates a drive signal based on a reference signal and provides the drive signal to a first coil via a single line and via a resonating capacitor, and simultaneously senses the drive signal via the single line, to facilitate electromagnetic coupling to a second coil to transfer power wirelessly to another device. The DSC also detects electrical characteristic(s) of the drive signal. The processing module(s) generates the reference signal and processes the digital signal to determine the electrical characteristic(s) of the drive signal. In some examples, the processing module(s) adapts the reference signal based on detection of the other device (e.g., based on interpreting the electrical characteristic(s) of the drive signal).

  • Patent number: 11935130
    Abstract: An aerial image system may generate images of structures providing views that might otherwise be difficult to obtain. These images may be used to determine various characteristics of the structure, which may then be processed for a variety of tasks including product marketing, claim processing and post-claim analysis. The images may be analyzed by the aerial image system or by a ground-based processing system to determine the structural characteristics such as roof age, roof type and roof pitch. In some examples, image analysis techniques such as edge detection and contrast determination may assist in determining the requisite data. Additionally or alternatively, the processing system may direct or control one or more image capture devices to obtain desired images.

  • Publication number: 20240090178
    Abstract: A cooling assembly includes an evaporator containing a primary cooling medium, a passive condenser, and a heat exchanger. When a secondary cooling medium is provided to the heat exchanger, the primary cooling medium in the gas phase switches from being received by the passive condenser to the heat exchanger without operating any valves located between the evaporator and the passive condenser and between the evaporator and the heat exchanger. The primary cooling medium circulates between the evaporator and the passive condenser and between the evaporator and the heat exchanger by natural circulation and gravity without a pump in the flow path of the primary cooling medium between the heat exchanger and the evaporator and between the passive condenser and the evaporator to circulate the primary cooling medium.
