    Abstract: 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.

    Abstract: In some embodiments, a microelectromechanical system may include a semiconductor substrate, a plurality of wiring layers, and a stop. The plurality of wiring layers may be coupled to a first surface of the semiconductor substrate. The stop may be coupled to the plurality of wiring layers. In some embodiments, at least a portion of the plurality of wiring layers between the stop and the first surface of the substrate comprises an insulating material. In some embodiments, at least the portion excludes wiring within. In some embodiments, a volume of the portion may be determined by a use of the microelectromechanical system. In some embodiments, the portion may inhibit, during use, electrical failures adjacent to the stop.

    Abstract: Electronic devices may be provided with magnetic sensors for detecting the Earth's magnetic field. The magnetic sensors may include thin magnetic sensors located in magnetically quiet regions of the device. The magnetic sensors may be attached to a device housing or a component such as a battery or a cover structure for a battery. The device may include unidirectional magnetic sensors aligned in three orthogonal directions or sensors with two or three magnetic sensor elements aligned in orthogonal directions. Magnetic field data from the three orthogonally aligned sensors or sensor elements may be combined to form directional compass data for the device. Each magnetic sensor may include one or more magnetic sensor elements for detecting the magnetic field and one or more shielded reference sensor elements for detecting environmental changes that can affect the magnetic sensor element. Reference sensor elements may be shared elements for multiple magnetic sensors elements.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
