  • Publication number: 20250103169
    Abstract: Disclosed herein is a touch sensor panel including a substrate, a plurality of conductive layers including a first conductive layer and a second conductive layer, a plurality of vias from the first conductive layer to the second conductive layer, and control circuitry mounted to a printed circuit. The control circuitry can include touch sensing circuitry. The first conductive layer can include a plurality of touch electrodes. The second conductive layer can be separated from the substrate by at least the first conductive layer and can include a bonding region with a plurality of bond pads for interconnection with the plurality of touch electrodes. The printed circuit can be separated from the substrate by at least the plurality of conductive layers and can be bonded to the plurality of bond pads by a conductive bonding material between the second conductive layer and the printed circuit.

  • Patent number: 12003117
    Abstract: A system for wireless power transfer includes a plurality of transfer elements, each transfer element of the plurality of transfer elements being configured as a transmitter for the wireless power transfer or a receiver for the wireless power transfer, a plurality of sensors, each sensor of the plurality of sensors being positioned relative to the plurality of transfer elements and configured to generate sensor data indicative of a field implementing the wireless power transfer, and a processor coupled to the plurality of sensors and configured to determine an estimate of a terminal variable level in a respective transfer element of the plurality of transfer elements based on the sensor data, and to determine whether a foreign object is affecting the wireless power transfer based on whether the estimated terminal variable level is different from another assessment of the terminal variable level by more than a threshold.

  • Patent number: 10732251
    Abstract: A system measures wireless power transfer between a transmitter and a receiver. The system includes a sensor circuit including a sensor. The sensor is configured and positioned to generate sensor data indicative of a field. The field is generated in connection with the wireless power transfer. The system further includes a processor coupled to the sensor circuit and configured to determine a power measurement based on the sensor data. The processor is further configured to determine misalignment of the transmitter or the receiver. The processor is also configured to correct an estimate of the power measurement based on the misalignment.
