    摘要： An electronic device can include a first and second portions that are pivotally coupled to each other so that the electronic device can have at least a closed configuration and an open configuration. A magnetic sensor system can be carried by the electronic device to detect the closed configuration so that the electronic device can automatically turn to a mode, such as a sleep mode, when the electronic device is bought to the closed configuration. A magnetic sensor can have a detection axis that targets a horizontal component of a magnetic field. A triggering magnetic element can be laterally offset relative to the magnetic sensor. The magnetic sensor can also be a magneto-resistive sensor. The electronic device can also include a second set of magnetic sensor system to confirm when the electronic device is brought to the closed configuration.

    摘要： An assembly for heat-generating components includes a metal and a non-metal layer. To secure to a circuit board that carries a heat-generating component, a metal standoff is secured on a perimeter of the circuit board. Multiple protruding elements of the metal layer of the assembly secure within a respective opening of the standoff. The assembly secures, through metal-to-metal contact, to the standoff by multiple mechanical couplings. The assembly not only covers the circuit board, but also extends laterally beyond the circuit board (and the circuit board components). As a result, the assembly receives thermal energy from a heat-generating component(s) on the circuit board and allows the thermal energy to flow through assembly from one portion of the assembly covering the heat-generating component(s) to the lateral portion of the assembly that does not cover the heat-generating component(s).

    摘要： An electronic device may have an upper housing and a lower housing separated by a slot. An antenna module may be mounted in the lower housing and may include a cavity. An antenna element may be disposed within the cavity. Grounded traces may be patterned onto walls of the module and may be coupled to conductive walls of the lower housing by conductive gaskets. The antenna element may have a high band arm displaced farther into the cavity than a low band arm by a shim. The antenna module may have an acoustic port aligned with a speaker port. The acoustic port may allow sound waves from a speaker to pass into the cavity from the speaker port. The cavity may be configured to optimize an audio response of the speaker while concurrently optimizing radio-frequency performance of the antenna element.

    摘要： A wearable band may include a first strap portion including a loop, and a second strap portion positionable through the loop of the first strap portion. The second strap portion may include a multi-pole magnet assembly, the multi-pole magnet assembly including two or more magnets arranged in a multi-pole magnet structure and at least one discrete shunt positioned over a surface of the multi-pole magnet structure.

    摘要： An efficient magnetic assembly having magnetic regions is formed by applying a magnetic field from a magnetizer to predefined portions of a monolithic substrate corresponding to the magnetized regions. In the described embodiment, the magnetic field is of sufficient strength and is applied for a sufficient amount of time to magnetize the corresponding portions of the monolithic substrate. A distance between at least two adjacent magnetized regions corresponding to a neutral zone is determined and based upon the determination, the monolithic substrate is shifted an amount less than the distance corresponding to the neutral zone and the magnetic field is re-applied to at least the shifted portion of the monolithic substrate.
