Inventor: SOGABE ERI
IPC: H05K9/00
Filed: 2002-05-17
Abstract: <P>PROBLEM TO BE SOLVED: To enhance a shielding effect by surely bringing the end of a tongue piece into elastic contact with the distal end peripheral edge of the cut hole of the inner surface of a shielding cover.  <P>SOLUTION: The tongue piece 33 cut except a root is formed at the flat plate 31 of a shield cover 3 for constituting a high-frequency unit. The piece 33 is formed with a root folding part 33b folded toward inward of the root, and another folding part 33c folded toward outward between the part 33b and a distal end 33a, and extended. Thus, when the cover 3 is mounted in a shielding case, the piece 33 is brought into contact with a shielding plate provided in the case, and the distal end 33a of the piece 33 is brought into elastic contact with the peripheral edge of the distal end of the cut hole 33x of the piece 33 on the inner surface of the cover 3.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a sales promotion supporting method which notifies a supplier of sales promotion contents of the effects of the sales promotion contents when the sales promotion contents such as catalogs and so on which a user wants are printed with a printer installed in a shop.  <P>SOLUTION: Printing data are generated in a transmission server 16 based on the electronic data of the sales promotion contents stored in a data server 5. At that time, an identifier for monitoring information on the purchasing behavior of a user of articles is added to the printing data. The transmission server 16 transmits the printing data to a printer 3. When the user buys the articles by the use of the printed matters, a printed matter use information input terminal 6 installed in the shop reads the identifier printed in the printed matter and notifies a management server 7 of the results of the reading. The fare computing section 60 of the management server 7 adjusts the ratio of burdens on the supplier for a fee charged for outputting the printed matter based on the use state shown by the identifier, and provides the supplier with the information on the user's purchasing behavior.  <P>COPYRIGHT: (C)2004,JPO

IPC: H04N9/07
Filed: 2002-05-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image pickup unit for processing automatic focus control at high speed while displaying an object image.   <P>SOLUTION: A CCD 21 of the image pickup unit has a first thinning out mode wherein longitudinal pixels of image data are thinned out to 1/8 at output of the image data and a second thinning out mode wherein longitudinal pixels of image data are thinned out to 1/16 at output of the image data. In the first thinning out mode, a first thinned out image can be outputted for a period of 1/30 seconds and in the second thinning out mode, a second thinned out image can be outputted for a period of 1/60 seconds. The number of longitudinal pixels of the second thinning out image is the number of longitudinal pixels of a liquid crystal monitor or below. In the case of automatic focus control, the second thinning out mode is selected and since a focus evaluation value FV is derived by 1/60 seconds each, the automatic focus is processed at high speed. On the other hand, the longitudinal pixels of the second thinning out image is interpolated to produce display image data ILV the number of longitudinal pixels of which is coincident with the number of longitudinal pixels of the liquid crystal monitor. Thus, the object image can be displayed on the liquid crystal monitor.  <P>COPYRIGHT: (C)2004,JPO

Title: Detection of data transmission rate using passing frequency selective filtering
Inventor: AMES STEPHEN JOHN
IPC: H04B10/43
Filed: 2002-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost, easily packaged and fully self-contained data rate detector and a method of data rate autodetection that allows selection of the data rate of an incoming data signal without an external control signal or complicated clock recovery system. SOLUTION: A data receiver, which can be an optical transmitter/receiver, a modem and a router hub can detect the transmission rate of incoming data. The data are converted to electrical waves suited to passive or active band pass filtering. A frequency at which the wave is filtered is determined from a plurality of known possible transmission rates and selected as a frequency having the most detectable difference in the power spectrums. By packaging the filter at a correspondent frequency, data having that (those) frequency(ies) are transmitted. Next, a signal detector receives a signal transmitted through the filter and a corresponding data rate can be determined. Further, a plurality of frequencies can be filtered by using the stages of filters and signal detectors corresponding to different frequencies or by filters and detectors capable of operation in a plurality of frequencies.
