A liquid crystal display device of the invention has: a display panel with an active matrix substrate 2 and a second substrate of transparent material deposed opposite that substrate; an illuminating unit that illuminates the display panel; and a photosensing unit that is provided on the active matrix substrate and has an ambient light photosensor that senses external light. The system comprises a point-of-sale transceiver configured to receive confidential information transmitted by a mobile device incorporating an electronic wallet and a signal generator in communication with the point-of-sale transceiver and configured to broadcast a jamming signal substantially concurrently with the point-of-sale transceiver receiving the confidential information. A handle extends from the body and on the opposing side is a pin removal bar at right angles to the body which has a sufficient length to extend beyond the teeth. When installed, the floor box assembly is held together by attachment fasteners extending from the mounting plate through the floor deck and the below-floor insulation kit. Then, the use of one of the network printer function and network scanner function of the image forming apparatus for which the trial mode has been set is permitted in accordance with a use request from a user. The system comprises search controlling means for receiving an allocated search resource and searching a multi-path of a radio channel to produce a search result; measuring means for measuring mobility of a terminal based on the search result; and allocating means for adaptively allocating a common search resource to the search controlling means based on a measure of mobility of the terminal.
