Communication device may include a transmitter and a receiver respectively coupled to one or more antennas to communicate (e.g., transmit or receive signals) with a base station. The communication device may receive an operating characteristic of a cellular modem within the communication device operating in a first cellular configuration and determine if the operating characteristic are greater than a threshold. The operating characteristic may include power and/or temperature. The threshold may include a power budget and/or a temperature threshold. If the operating characteristic is greater than the threshold, then the communication device may determine a control effort value based on the operating characteristic and the threshold. The communication device may map the control effort value to a second cellular configuration, which may correspond to reduced operating characteristics in comparison to the first cellular configuration. The communication device may then cause the cellular modem to operate in the second cellular configuration.

A wireless power transmitting device may transmit wireless power signals to a wireless power receiving electronic device. The electronic device may have a coil that receives the transmitted wireless power signals and may have a power receiving circuit that rectifies the received wireless power signals to produce a corresponding direct-current voltage signal. The direct-current signal may be used to power circuitry in the electronic device and may be used to charge a battery in the electronic device. Control circuitry in the electronic device may use a temperature sensor to make temperature measurements. In response to detecting that the device is below a given threshold temperature and based on other information such as information on which applications are running on a controller in device, the device may supply drive current signals to the coil to heat the battery and improve battery performance.

The present disclosure is related to printed circuit board packages and methods of assembly that may be used in the fabrication of electrical devices. Printed circuit board packages may be manufactured by stacking printed circuit board assemblies. Each printed circuit board assembly may have multiple printed circuit boards supported by a resin mold. The printed circuit board assemblies may be shaped to improve space utilization efficiency and to accommodate large electrical components that are attached to the printed circuit board package.

Stacked printed circuit board packages

A circuit board assembly in an electronic is disclosed. To conserve space in the electronic device, the circuit board assembly includes stacked circuit boards in electrical communication with each other, such as a first circuit board stacked over a second circuit board. Each circuit board may include multiple surfaces that carry operational components. Moreover, the first circuit board may include a first surface and the second circuit board may include a second surface facing the first surface. The first and second surfaces may include operational components in corresponding locations. Also, the operational components may include corresponding shapes such that one component is positioned in another component. The components may electrically connect to each other. Also, the circuit board assembly may include EMI shields around an outer perimeter in order to shield the operational components form EMI and to components in the electronic device from EMI emanating from the operational components.

Stacked circuit board architecture in an electronic device

A handheld communication device is used to capture a video and stabilize the video during a video chat session. The device has a camera to capture a video during a video chat session that is conducted between a user of the device and a far-end user. The video includes images frames, each of the image frames containing an image of a face of the user. The device detects the position of the face in each image frame. Based on the detected position of the face, a boundary area of each image frame is cropped to produce an output video while the video is being captured. The image of the face stays substantially stationary in the output video. The output video is transmitted to the far-end user during the video chat session. Other embodiments are also described and claimed.

Face detection as a metric to stabilize video during video chat session

An embodiment of the invention is directed to a relatively low cost technique for improving the sharpness or quality of digital images captured by a handheld portable media device. A housing of the device has integrated therein a digital camera image sensor, a camera lens, and a sensor that detects a distance measure, which is a measure of distance between the housing and an object or target in a scene that is before the lens. The device is programmed to select a point spread function, PSF, based on the detected distance measure. The selected PSF is then applied to de-blur the captured image, for becoming the final picture of the scene that is taken by the user. Other embodiments are also described and claimed.

Using distance/proximity information when applying a point spread function in a portable media device

An electronic device may operate in standby and active modes. A headset may be coupled to the electronic device. The electronic device may have audio codec circuitry. The audio codec circuitry may use general purpose input-output circuitry in handling button and headset activity during active mode. Processing circuitry may be used to reconfigure the audio codec in real time. When the electronic device is in the standby mode and activity is detected, the codec may be configured to provide an interrupt signal to a power management unit that wakes the device. When the electronic device is in active mode and no user inputs are received within a given period of time, the central processor in the electronic device may place the device in standby mode.
