Abstract: The present invention provides a data storage apparatus with a multiple serials interface. The data storage apparatus is including a memory providing for data storing; a microprocessor used for controlling the access of a data stored in the memory; two serial bus interfaces connecting to the microprocessor or built-in in the microprocessor, wherein those two serial bus interfaces are including a universal serial bus (USB) interface and at least a non-USB interface for dealing with a communication protocol and a transmission of the connecting interface; a connecting port, wherein the connecting port is USB compatible and is electrically connecting with the serial bus interfaces for providing the connection to a digital apparatus to form an interface connection relation thereof; and an interface switch controller used for detecting an interface property connected by the connecting port and to converting to the corresponding serial bus interface.

Abstract: A remote controller for independently controlling a plurality of electric appliances includes a selector device for outputting a selected signal for controlling an electric appliance and a memory electrically connected to the selector device for storing a plurality of codes, such codes consisting of device codes, address codes, and function codes, wherein the device codes designate electric appliances of a particular type (such as TV's, VCR's audio sets, etc.), the address codes designate a specific appliance of the particular type (such as TV no.1, TV no. 2, ect.), and the function codes designate control of a function of the appliance (such as volume, picture contrast, color, etc.).
