Abstract: A flight recorder includes an enclosure having a notch formed on one side or corner of the enclosure. An electronic interface is disposed within the enclosure. The electronic interface is coupled for receiving flight data, video data, and audio data. A memory unit is disposed within the enclosure and electrically connected to the electronic interface for storing the data. The memory unit contains a non-volatile memory device. A reserve power supply is physically disposed within the notch of the enclosure. The reserve power supply contains a rechargeable battery. A clamp secures the reserve power supply to the enclosure to make the reserve power supply removable from the enclosure. The reserve power supply has an electrical connector coupled to the enclosure for providing an operating voltage to the electronic interface and memory unit. The reserve power supply and electrical connector physically reside within a form factor of the enclosure.

Abstract: A flight data recorder includes an enclosure and electronic interface within the enclosure. The electronic interface is coupled for receiving data. A crash survivable memory unit is disposed within the enclosure. The crash survivable memory unit includes a memory module electrically coupled to the electronic interface for storing the data. A locator beacon is disposed within the enclosure or within the crash survivable memory unit. The locator beacon is an acoustic resonator which emits ultrasonic pulses. A battery is disposed within the enclosure or within the crash survivable memory unit for providing operating power to the locator beacon. The battery is rechargeable. The battery status is stored in the memory module. A beacon control circuit is disposed within the enclosure or within the crash survivable memory unit for monitoring the battery. A beacon activation device detects a crash event and notifies the beacon control circuit to activate the locator beacon.
