摘要： An acoustic imaging system coupled to a sensing plate to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers coupled to the sensing plate opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.

摘要： An acoustic imaging system includes multiple transducers disposed to circumscribe a portion of substrate. An acoustic imaging system also includes a controller and an image resolver. The transducers convert electrical signals into mechanical energy and/or mechanical energy into electrical signals. The controller is adapted to apply an electrical signal to the transducers which, in response, induce a mechanical wave, such as a surface wave, into the circumscribed portion. The controller is also adapted to receive electrical signals from the transducers. The image resolver uses the electrical signals received by the controller in order to construct an image of an object in physical contact with the substrate.

摘要： An electronic device may be provided with an electronic compass. The electronic compass may include magnetic sensors. The magnetic sensors may include thin-film magnetic sensor elements such as giant magnetoresistance sensor elements. Magnetic flux concentrators may be used to guide magnetic fields through the sensor elements. The magnetic flux concentrators may be configured to reduce the angular sensitivity of the magnetic sensors. A magnetic flux concentrator may be formed from multiple stacked layers of soft magnetic material separated by non-magnetic material. The non-magnetic material may have a thickness allows the magnetic layers to magnetically couple through the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction.

摘要： An electronic device may include one or more low-noise pressure sensors for measuring air pressure. The electronic device may include wireless communications circuitry for communicating with external devices also having pressure sensors. Pressure data gathered by an external device may be used as reference pressure data for the electronic device. For example, if both devices are located in the same building, both pressure sensors will detect similar pressure fluctuations due to doors opening and closing and temperature-control systems turning on and off. By subtracting the reference pressure data from the pressure data gathered by the electronic device, calibrated pressure data may be obtained and may be used to reliably detect vertical displacement changes of the electronic device. In other scenarios, the pressure data may be compared with the reference pressure data to determine whether the two devices are in the same MOM.

摘要： Systems, methods, and computer-readable media for calibrating the offset of a magnetometer assembly with reduced power are provided. In one embodiment, a method for operating an assembly may include determining a difference between a current signal measurement output component of a first magnetometer sensor and a previous signal measurement output component of the first magnetometer sensor, comparing the determined difference with a current threshold value, and generating an assembly output based on the comparing, where, when the determined difference is greater than the current threshold value, the generating may include providing a first assembly output using a current offset output component of a second magnetometer sensor, and, when the determined difference is less than the current threshold value, the generating may include providing a second assembly output using a previous offset output component of the second magnetometer sensor.

摘要： The described embodiments relate generally to a capacitor assembly for mounting on a printed circuit board (PCB) and more specifically to designs for mechanically isolating the capacitor assembly from the PCB to reduce an acoustic noise produced when the capacitor imparts a piezoelectric force on the PCB. Termination elements in the capacitor assembly, including a porous conductive layer in the capacitor assembly may reduce an amount of vibrational energy transferred from the capacitor to the PCB. Termination elements including a soft contact layer may also reduce the amount of vibrational energy transferred to the PCB. Further, capacitor assemblies having thickened dielectric material may reduce the amount of vibrational energy transferred to the PCB.

摘要： An electronic device may be provided with electronic components such as buttons and environmental sensors. An environmental sensor may be temperature sensor for gathering temperature data associated with the environment surrounding the device. The temperature sensor may be mounted to a button member for the button. The button member may be an actuating member that moves within an opening in a device housing and that extends beyond an outer surface of the housing into the surrounding environment. The button member may be arranged so that an internal electronic switch is activated when the button member is moved within the opening. The button member may be thermally isolated from other device structures using insulating material on the button member. The button member may be formed from a thermally conductive material that transmits the temperature of environmental materials that contact the button member to the temperature sensor.
