Abstract: A case for an electronic device can include a case body including an exterior surface and an interior surface, the interior surface being positioned opposite the exterior surface. The case can additionally include a button body positioned at least partially within the case body between the exterior surface and the interior surface, the button body being movable inward and outward relative to the case body along an axis of button travel. The case can further include a biasing structure having a contact surface configured to contact the button body, the biasing structure configured to bias the button body toward the interior surface along the axis of button travel.

Abstract: An electronic device such as a cellular telephone or other device may have a housing with front and rear faces joined by a sidewall. A display may be mounted on the front face. The electronic device may include multiple ambient light sensors such as a front ambient light sensor on the front face and one or more supplemental ambient light sensors on the rear face and/or on the sidewall. The front ambient light sensor gathers a front ambient light intensity measurement and the supplemental ambient light sensor gathers a supplemental ambient light intensity measurement. During operation, control circuitry in the electronic device adjusts the display brightness based on data from the ambient light sensors. The control circuitry may implement power saving restrictions that limit when the supplemental ambient light intensity measurement is taken into account and/or that impose a brightness cap on the display brightness.

Abstract: A power system for powering a pulsed load that intermittently delivers current pulses can include: an energy reservoir; a first DC-DC converter having an input that receives an input voltage and an output coupled to the energy reservoir; a second DC-DC converter having an input coupled to the energy reservoir and an output couplable to the pulsed load; and control circuitry that operates the first DC-DC converter to charge the energy reservoir from a minimum or valley voltage to a maximum or peak voltage during a charging window just prior to a current pulse of the pulsed load so that the first DC-DC converter is at or near its maximum output current at a beginning of the current pulse of the pulsed load.
