Title: Recorder of crime preventing system
Inventor: MATSUMOTO MITSUHIRO
IPC: G08B13/196
Filed: 2002-02-04
Abstract: <P>PROBLEM TO BE SOLVED: To save the recording capacity of a recording medium in a recorder of a crime prevention system without deteriorating the reliability of this system.  <P>SOLUTION: At a reference image register mode, the recorder stores insulation information for one frame of a RAM as a reference image in an EEPROM (S102). If not at the reference image register mode, it stores the image information for one frame of the RAM in a RAM in a system controller 22. If no manual switch is operated or an external signal SIG is inputted, the recorder executes a comparing process routine for checking if a photographed image changes, relative to the reference image. If any change is seen, the recorder executes a step of extracting only a region containing changed portions of the photographed image, relative to the reference image (S112). If no change is seen on the photographed image, relative to the reference, it executes a step of deleting and reducing pixels over the entire region of the photographed image (S114).  <P>COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide an optical signal transmission testing method and an optical transmission line simulator, which simulate the environment more closely to an installed fiber actually and to estimate the quality of a PMD compensator and transmitting and receiving equipment. SOLUTION: The optical signal transmission testing method simulates signal waveform deterioration due to polarization mode dispersion (PMD), in a transmission line between a transmitting side and a receiving side of optical transmission equipment. A signal light, outputted from the transmitting side, is divided into two orthogonally polarized waves. Delay which does not depend on wavelength is given to one divided signal light, and delays. Delay (dispersion) different in wavelength are given to the other divided signal lights. After that, the two signal lights are multiplexed and received by a system, which controls the delay and dispersion and changes the first order PMD and higher order PMD, in the optical signal transmission testing method and the optical transmission line simulator.
