Abstract: An apparatus is disclosed. The apparatus comprises a primary power supply (PPS) configured to supply primary power, a PPS sensor configured to measure the power supplied by the PPS and provide a PPS measurement signal indicating an amount of the power supplied by the PPS, a backup power supply (BPS) configured to be provided in an emergency data system and further configured to supply backup power to a modem, and an integrated circuit configured to maintain a clock using the power supplied by the PPS. The integrated circuit is configured to receive the PPS measurement signal from the PPS sensor, determine whether the PPS measurement signal falls below a threshold, and maintain the clock using the power supplied by the BPS in response to a determination that the PPS measurement signal has fallen below the threshold.

Abstract: Certain aspects of the present disclosure generally relate to testing functionality of the display system. An example method generally includes selecting a first data integrity check value, associated with a region of interest (ROI) of an input frame, among a set of data integrity check values stored on a memory device, the data integrity check values are associated with an animation comprising a plurality of frames, and at least one of the frames of the animation corresponds to the input frame; processing, with a display processor, the input frame; calculating a second data integrity check value on the ROI of the input frame after the display processor processes the input frame; comparing, with a comparator, the data integrity check values; and generating, with the comparator, an interrupt if the comparison indicates that the values do not match.
