Abstract: A regulator draws power from a battery or power delivery system and supplies regulated power to a load according to alternating modes of operation. In a voltage control mode, the regulator supplies power with a nominal voltage level and a fluctuating current level that is allowed to float according to the current demands of the load. When the load demands an amount of current that could potentially cause damage, the regulator transitions to a current control mode. In the current control mode, the regulator supplies power with a fluctuating voltage level and a maximum current level. The regulator transitions between voltage control mode and current control mode in order to supply a maximum power level to the load without exceeding the maximum current level. The regulator is also configured to limit the power drawn from the battery by decreasing the maximum output current, potentially avoiding voltage droop.

Abstract: Embodiments are disclosed for a touch-based device and methods for operation thereof. One embodiment provides a touch-based device having a display with a plurality of pixels and a touch input sensor overlying the display. The touch input sensor has a plurality of touch regions, each of which overlie an associated set of the pixels. The touch-based device further comprises a display controller configured to update the pixels according to a schema during which pixels are updated during update periods. The touch-based device yet further comprises a touch controller configured to recognize selectively applied touch inputs at the plurality of touch regions. The touch controller and the display controller are synchronized such that, for a given touch region, touch input recognition is modified while the display controller is updating the set of pixels associated with that touch region.
