    Abstract: A fault recovery system includes various fault management circuits that form a hierarchical structure. One fault management circuit detects a fault in a functional circuit and executes a recovery operation to recover the functional circuit from the fault. When the fault management circuit fails to recover the functional circuit from the fault within a predetermined time duration, a fault management circuit that is in a higher hierarchical level executes another recovery operation to recover the functional circuit from the fault. Such a fault management circuit is required to execute the corresponding recovery operation within another predetermined time duration to successfully recover the functional circuit from the fault. The fault recovery system thus implements the hierarchical structure of fault management circuits to recover the functional circuit from the fault.

    Abstract: A system and method for a radar system are provided. The radar system includes a leader radar device that includes a first clock generation circuit configured to generate a first clock signal, and a first transmitter and receiver configured to transmit and receive radar signals using a first local oscillator signal. The system includes a follower radar device. The follower radar device is configured to receive the first clock signal and the first local oscillator signal from the leader radar device. The follower radar device includes a second clock generation circuit configured to generate a second clock signal, wherein, in a default operational mode of the radar system at least a portion of the second clock generation circuit is disabled, and a second transmitter and receiver configured to transmit and receive first radar signals.

    Abstract: An event manager for filtering safety and security events of a system including an event sequence list including predetermined event sequences in which each sequence includes at least one event identifier identifying a corresponding one of multiple monitored events, an event sequence array that stores a received event sequence in response to received event notifications, and a controller that stores an event identifier into the event sequence array and that determines whether the received event sequence matches at least one of the predetermined event sequences for determining a composite event and a response for each received event notification. The matching determination may be made with or without consideration of chronological order. A suspected composite event may be identified when multiple possible matches may exist, and a final composite event is ratified when only one match is found. An exception may be generated upon timeout of a timer.
