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.

Power management in an automotive vehicle

Systems and method for error detection in automobile tell-tales are provided. An initial cyclic redundancy check (CRC) for a tell-tale to be calculated and stored at a primary control system within the vehicle. When a fault or condition is detected which generates the tell-tale, the primary control system passes video information to a display embedded control unit (ECU) along with the initial CRC. A circuit in the display ECU performs its own CRC calculation and compares the initial CRC to the calculated CRC. If there is not a match, then a fault indication may be provided to the primary control system for action by the primary control system. Still further, back up or fail-operational options may be invoked so that the tell-tale is provided to the operator.
