Abstract: A mobile station transmits a physical address given to the mobile station to a connection device via a base station when subscribing to a communication system. The connection device previously stores the physical address given to the mobile station and an IP address in a table of the connection device in association with each other, searches the table for the IP address corresponding to the physical address transmitted from the mobile station from the address storage section, generates a header compression rule in accordance with the IP address searched for, and transmits the generated header compression rule to the mobile station via the base station.

Abstract: A method of driving a display device assumes a specific pixel on a retina that is formed on the retina based on an input image, and controls light emission of each subframe such that luminance of a specific pixel on the retina becomes substantially equal to luminance of a pixel corresponding to the input image. The display device is driven by constructing one frame with a plurality of subframes, for displaying the input image that moves on a display panel.

Abstract: A game cartridge is inserted into a game device, and a controller is operated to display and perform a game stored in the game cartridge on a display monitor. The game cartridge has a ROM for storing a game program and a RAM for storing data of a play character having unique abilities. The controller is operated to instruct a play character to repeat various patterns of speech and action to increase the number of "remaining experience credits". Obtained "remaining experience credits" are assigned to abilities of the play characters to achieve desired ability values for thereby growing the play character until it develops unique abilities.
