The disclosure is related to a method of managing and controlling vehicles for safe driving. A receiver circuit within the instrument divides the path into an analog path and a digital path. Generation of the digital signature accounts for a unique identifier nominally associated with the computing device. Chips are bonded onto the first patterned solder resist layer such that the first patterned solder resist layer is between the chips and the patterned conductive layer. The power supply coil is electrically connected with a battery unit. The data recovery device reads the data from other semiconductor memory device in response to the data recovery request to recover the data, and returns a recovery result to the padding unit in the storage control device to perform the padding process.
