    摘要： One embodiment relates to testing and verifying vibrator motor operation during manufacturing of a device and during in-the-field use. The test relies on an integrated motion sensor or other mechanical measurement circuitry, such as, for example, an accelerometer. In one embodiment, a speed determination for a vibrator motor performance during initial manufacture of the device. Subsequently, when vibration is detected during the in-the-field use, the vibration may be sampled using the integrated mechanical measurement circuitry. Once sampled, a speed may be determined based on a resonance of the sampled signal. Over time, the various speed determinations for the vibrator motor may be analyzed to determine an overall health of the vibrator motor. A threshold for detecting when the overall health of the vibration motor over time has degraded may be predetermined. A notification of a degradation of vibrator motor performance is sent to either a manufacturer or user of the mobile communications device. Other embodiments are described and claimed.

    摘要： An electronic device having one or more sensors is provided. The sensors may include any suitable type of sensor that emits or receives radiation (e.g., light waves) from the environment. The electronic device may include openings through which radiation may reach the sensors while keeping the sensors hidden from view. In some embodiments, the sensors may be placed underneath an opening used for an audio receiver such that radiation is piped to the sensors using a light path or a chamfered surface along the opening. In some embodiments, the sensors may be embedded in a screen such that the radiation emitted by the sensors exits the screen instead of being reflected on the screen. In some embodiments, the sensors may be placed along the periphery of the display, such that access to the sensors is provided via discontinuities in a gasket used to couple the display to the electronic device.

    摘要： Embodiments described herein take the form of fixtures to be used in a manufacturing process. In particular, a manufacturing fixture may be sized to accept one or more electronic components, such as a printed circuit board (PCB) having various electrical elements. The PCB may be placed on the fixture in a predetermined area. The PCB may be placed in a depression or aperture sized to accept the PCB. When the PCB is placed within the fixture, a cover may be lowered or otherwise placed across the PCB in order to hold the PCB in place. The cover contacts the PCB and is pliable or malleable to conform to those portions of the PCB it contacts. When the cover is closed, a negative pressure may be induced in the fixture beneath the cover. When the PCB is held in position, the manufacturing fixture may operate on the PCB.

    摘要： A portable electronic device has a battery to provide power to operate the device, a connector including a power supply pin to be coupled to an external power supply, and a power manager having a battery charger circuit that draws power through the power supply pin to charge the battery. The power manager has a current limit feedback control loop that limits the drawn current in accordance with a predetermined output current rating of the external power supply. The power manager automatically changes the behavior of its control loop to stabilize operation of the coupled external power supply. Other embodiments are also described and claimed.
