A hand display control device includes a processor. The processor causes an oscillation circuit to output a first frequency signal or a second frequency signal to a first processing circuit that executes processing for operating a hand in response to the first frequency signal. The oscillation circuit outputs the first frequency signal or the second frequency signal by switching. The second frequency signal is higher in frequency than the first frequency signal. The processor controls whether to output the second frequency signal to a second processing circuit that performs previously determined certain processing in response to the second frequency signal. The processor controls the switching of the oscillation circuit depending on whether the certain processing is performed. The processor prohibits the first processing circuit from performing a specific operation of the hand while the second processing circuit is performing the certain processing.

An optically communicative battery management system includes a pack controller and one or more module controllers optically coupled to the pack controller. The module controllers may themselves be optically coupled together in series, and communication from an upstream module controller may be relayed through one or more downstream controllers en route to the pack controller. The pack controller may also send an optical signal that is used by the pack controller to determine whether any one or more of the battery modules is experiencing a safety fault, and the communication channel used to transmit that optical signal may, absent any safety faults, be used to multiplex message data to the module controllers.
