Abstract: A radar system includes a plurality of radar devices each having a transmitting unit that transmits a high frequency signal to an object, a receiving unit that receives a signal reflected from the object, an individual control unit that controls transmission and reception timings, and a converting unit that converts an output of the receiving unit into digital data, and a central processing device having an integration process unit that processes information transmitted from the radar devices in association with positional information of the radar devices, a command control unit that controls operation timings of the individual control units, and a detection process unit that performs a process for detecting the object on the digital data before being processed by the integration process unit. Digital communication isolated from the transmission and reception timing controls at the individual control unit is performed between the radar devices and the central processing device.

Abstract: Provided is a pulse generator that generates a pulse signal with a preferred waveform and offers increased isolation for a period of time when the pulse signal is not output. A pulse generator 100 allows a high-frequency oscillator 101 to output a high frequency signal and allows an amplifier 102 to amplify and output the signal. The amplifier 102 amplifies the high frequency signal from the high-frequency oscillator 101 and outputs the signal only for a period of time when its drive power is supplied by a drive circuit 110. The waveform of the drive power, supplied from the drive circuit 110 to the amplifier 102, is controlled by a waveform control unit 120 such that the high frequency signal amplified by the amplifier 102 becomes an ultra-wideband pulse signal.

Abstract: A system quickly accesses suitable represented information, in view of a lapse time from retrieval result display to user move. A system control section (SCS) of a retrieval system server accesses a retrieval database registering retrieval priorities to be associated with respective web pages. The SCS sends a retrieval result page on which the retrieval result is to be displayed, from the web page having the higher retrieval priority on a priority basis, receives, after sending the same, a re-retrieval request or a request for the other retrieval result page, indicating a sending request for the new retrieval result page, and measures lapse time “t”.

A system control section (SCS) of a retrieval system server accesses a retrieval database registering retrieval priorities to be associated with respective web pages. The SCS sends a retrieval result page on which the retrieval result is to be displayed, from the web page having the higher retrieval priority on a priority basis, receives, after sending the same, a re-retrieval request or a request for the other retrieval result page, indicating a sending request for the new retrieval result page, and measures lapse time “t”. If “t”<threshold time “a”, the SCS decreases retrieval priorities of the web pages, indicated by the retrieval result terminal display. If “t”?“a”, the SCS increases retrieval priorities of the web pages, indicated by the retrieval result displayed by the user terminal.

Abstract: A multi-display apparatus including: a plurality of display devices which are remotely controllable by a remote controller; an ID number storing unit which stores ID numbers for identifying the plurality of the display devices; a detailed screen adjustment information display unit which simultaneously displays a detailed screen adjustment information for designating the ID number on display screens of the display devices according to an instruction from the remote controller; a screen adjustment menu display unit which displays a screen adjustment menu on the display screen of the display device, which corresponds to the designated ID number, by a key operation of the remote controller; and a screen adjustment unit being capable of adjusting the display screen of the display device on a basis of the screen adjustment menu.
