Abstract: A card adapter device includes a card slot for receiving a micro SD card therein; a SD interface for coupling electrically to a portable electronic device; a processing chip including a dynamic switch coupled electrically to the card slot and the SD interface, and a processor unit coupled electrically to the dynamic switch; and a wireless transmission/reception interface coupled electrically to the dynamic switch. Upon receiving a first signal from the wireless transmission/reception interface, the dynamic switch detects an operation mode of the SD interface and upon detecting that the SD interface is in an idle mode, the processor unit converts the dynamic switch to be coupled electrically to the wireless transmission/reception interface, thereby enabling the dynamic switch to transfer the first signal to the card slot, which, in turn, enables the wireless transmission/reception interface to access into the SD card.

Abstract: A bus emulation device in accordance with one aspect of the present description includes an embedded microcontroller and a nonvolatile memory carried on a body. The memory contains firmware which includes boot code adapted to boot the microcontroller to operate in one of a plurality of dedicated operating modes in response to a mode switch. These dedicated operating modes include a learning mode in which bus signals generated by other bus devices are recorded in the nonvolatile memory, and an emulation mode in which recorded bus signals are retransmitted over the bus in response to received signals, to emulate a bus device. Other aspects are described and claimed.

Abstract: A multimedia storage card system includes a memory card; a dynamic switch coupled electrically and communicatively to the memory card; a first accessor coupled electrically and communicatively to the dynamic switch for accessing to the memory card, thereby storing data into and retrieving data from the memory card; and a second accessor coupled electrically and communicatively to the dynamic switch. Upon receipt of a first access signal transmitted from the second accessor, the dynamic switch determines whether the first accessor is in an idle condition. Upon detecting the first accessor is in the idle condition, the dynamic switch is switched to and in communication link with the second accessor, thereby transmitting the first access signal to the memory card and enabling the second accessor to access the memory card in order to store data into and retrieving data from the memory card.
