Abstract: 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.

Abstract: 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.

Abstract: The subject matter of the disclosure relates to low temperature power throttling at a mobile device to reduce the likelihood of an unexpected power down event in cold weather environments. A mobile device employing a power management solution may be configured to determine that a monitored temperature at the mobile device (at the battery of the mobile device) is below a first threshold level, and whether a hardware component (such as a camera) is active or inactive. Then, based on these determinations, the mobile device can select a throttle setting from a first set of throttle settings when the hardware component is active, and a second set of throttle settings when the hardware component is inactive. Subsequently the mobile device can throttle power consumption for one or more components of the mobile device according to the selected throttle setting.

Abstract: Methods and apparatuses are disclosed that provide increased control of backlit keys for a keyboard. Some embodiments may include controllers within the keyboard that are capable of dynamically programming illumination of the keyboard based upon interaction, where each key of the keyboard may be individually programmed in a dynamic manner. For example, a spell checking function may be executing on a computer system, and as the user types various words, the keyboard may dynamically program the illumination of keyboard controllers such that the next letter of the word being typed is illuminated by the keyboard. Also, different keyboard illumination schemes may be generated based upon mouse movements by the user and/or based upon which application is currently executing.

Abstract: The disclosed embodiments provide a system that enables a portable computing device to receive power through multiple bus interfaces at the same time. When the system senses that a first power source is plugged into a first bus interface in the portable computing device, the system determines whether the first power source is a host or a power adapter. Next, based upon whether the first power source is a host or a power adapter, the system uses a first power manager coupled to the first bus interface to limit a first input current received from the first power source to power the computing device. The system also provides the maximum charging current to a rechargeable battery for the portable computing device by chaining together a second bus interface whether power is present on the second bus interface or not.

Abstract: A method for depth sensing keystoning. The method of depth sensing keystoning may include an optical system and electrical devices. The method of depth sensing keystoning may correct for image distortion using depth measurements.

Abstract: The disclosed embodiments provide a system that facilitates communication between components in a portable electronic device. The system includes a first hub that couples a first set of interfaces to a high-speed link and a second hub that couples a second set of interfaces to the high-speed link. The first hub may receive a communication from a first component through a first interface in the first set of interfaces and transmit the communication through the high-speed link. The second hub may receive the communication from the high-speed link and transmit the communication to a second component through a second interface in the second set of interfaces. The first and second hubs may thus reduce the number of wires required to transmit communications between the first and second sets of interfaces.

Abstract: The disclosed embodiments provide a system that configures a battery for a computer system. During operation, the system disconnects the battery by simulating a fault condition using a safety circuit of the battery. The fault condition may be simulated to facilitate safe assembly of a computer system containing the battery. After assembly is complete, the system enables use of the battery in the computer system by applying external power to the computer system, which resets the safety circuit and reconnects the battery.
