Abstract: The present invention relates to a compound capable of lowering the flammability of a non-aqueous electrolyte when included in the non-aqueous electrolyte and improving the life properties of a battery by forming an electrode-electrolyte interface which is stable at high temperatures and low in resistance, and relates to a compound represented by Formula I descried herein, a non-aqueous electrolyte solution and a lithium secondary battery both including the compound, n, m, Ak, and X are described herein.

Abstract: An apparatus for executing user commands in digital equipment operating in a USB mass storage (UMS) mode is configured in such a manner that a USB connecting unit transmits and receives commands and data to and from a PC serving as a host through a universal serial bus (USB) port. A USB control unit controls the USB connecting unit. A storage unit stores an access command table including access commands allocated respectively to address shift values, by which addresses contained in one or more user commands received from the PC deviate from a valid address range. A microcomputer determines whether the command received through the USB connecting unit is a user command. If it is determined that the received command is a user command, the microcomputer controls executing the access commands allocated respectively to the address shift values based on the access command table.
