Abstract:
A memory system that includes a memory array and a memory controller manages power consumption by maintaining a variable credit value that reflects the amount of power available to the memory system. The variable credit value may be increased periodically up to a limit. When a power-consuming operation is performed, the variable credit value is reduced to reflect the power used.

Abstract:
A memory controller for a memory card such as an SD card with an additional host interface such as a USB interface comprises a duplicate SD interface. Embodiments with two SD interfaces may also comprise a card reader controller chip that can be turned off by the memory controller when the USB interface is not needed. Incorporation of the additional SD interface in the controller allows for an economical or off the shelf card reader controller to be employed.

Abstract:
The present system for recording vehicle-related data does not involve an elaborate installation procedure and thus may be routinely transferred from one vehicle to the next. The system has a recording module and at least on sensor module. The recording module has a wireless receiver, a processor, a vehicle interface assembly, and a data processor interface. The vehicle interface assembly enables the recording module to detachably connect to the vehicle. The sensor modules have a sensor, a processing subsystem, and a wireless transmitter. The wireless transmitter of a sensor module communicates with the wireless receiver of the recording module. Also disclosed is a method of recording vehicle related data.
