IPC: H04W64/00
Filed: 2003-06-26
Abstract: <P>PROBLEM TO BE SOLVED: To enable a portable telephone set with a camera to manage an image pickup position without incorporating a device such as a GPS receiver.  <P>SOLUTION: Base station identification information is obtained from a base station 114, and position information corresponding to it is transmitted to a server 111 which is previously stored through a communication network 112. Position information corresponding to the base station identification information obtained from the server is received and it is managed as the position information of a picked up image. Base station identification information is obtained at the time of supplying power at prescribed timing before image pickup, for example. Base station identification information is obtained again just after image pickup. When the base station is changed by hand-over, position information differs when power is supplied and immediately after image pickup. Thus, position information immediately after image pickup is set to be correct and it is used for management of the picked up image.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: G01N1/02
Filed: 2003-07-02
Abstract: <P>PROBLEM TO BE SOLVED: To measure particulates contained in an exhaust gas continuously inclusive of the data related to the particle size of fine particles.  <P>SOLUTION: The exhaust gas and a feed gas are allowed to flow in a classifying passage in a mutually layered state. The particulates in the exhaust gas are charged by the charger provided on the upstream side in the classifying passage and an electric field is formed on the downstream side thereof in the direction traversing the flows of both gases. A plurality of sampling ports are provided on the side surface of the classifying passage so as to be positionally different from each other in the flow direction. The particulates in the exhaust gas receive the effect of the electric field to move in the direction traversing the flows of the gases to arrive at the wall surface of the classifying passage. The particulates thus moved are taken in from a plurality of the sampling ports to be detected by a particle detector. Since the moving speed of smaller particulates is high, small particulates are detected at the sampling port on the upstream side of the flows of the gases and the larger particulates are detected on the downstream side. By this method, the particulates in the exhaust gas can be continuously detected while classified.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
