Abstract: This application discloses electromagnetic energy mitigation assemblies and automotive vehicle components comprising the electromagnetic energy mitigation assemblies. An electromagnetic energy mitigation assembly includes a first electrically conductive layer and a second electrically conductive layer. First and second permalloy layers are along respective first and second opposite sides of the first electrically conductive layer. Third and fourth permalloy layers are along respective third and fourth opposite sides of the second electrically conductive layer. An electromagnetic noise suppression layer is sandwiched between the second and third permalloy layers. An automotive vehicle component includes an electromagnetic energy mitigation assembly configured to be positioned relative to one or more batteries of an automotive vehicle for providing electromagnetic shielding for the one or more batteries. The electromagnetic energy mitigation assembly includes a first electrically conductive layer.

Abstract: A node device switches from a sleep mode to a wake-up mode when the node device needs to transmit information. The node device transmits a synchronization signal to the another node device based on the information and determines whether an acknowledgement signal is received. The node device transmits the key-frames to the another node device when the acknowledgement signal is received.
