Title: Fingerprint collating method
Inventor: IGAKI SEIGO
IPC: G06K9/00
Filed: 1989-09-28
Abstract: PURPOSE:To improve the reliability of fingerprint collation by storing previously plural fingerprint pictures in a frame memory at the time of registering reference data or at the time of collating, and extracting feature information from these plural binary data read out from the frame memory. CONSTITUTION:The fingerprints read out while a finger is pushed to a fingerprint sensor 1 are read out as plural frame pictures, and the feature information of the fingerprint of every frame picture is stored beforehand as the feature quantity of the corresponding fingerprint in a reference data file 5 in the order of the plentifulness of coincidence points extending over plural frame pictures. Then, while the objective finger to be collated is pushed to the fingerprint sensor 1, the fingerprint is read as plural frame pictures, which are compared with the feature quantity of the fingerprint read out from the reference data file 5, and in the case where the coincidence pints with the feature quantity are more than a prescribed threshold in, at least, one frame picture or in the case where the coincidence points with the feature quantity are more than the prescribed threshold extending over the frame pictures more than the prescribed number, the fingerprint is decided to coincide. Thus, the fingerprint can be collated with high reliability.

Title: Power source switching system
Inventor: NEGISHI MICHIAKI
IPC: H01H33/59
Filed: 1995-09-29
Abstract: PURPOSE: To input a power source switch in waiting, at a service interruption, just after the power source switch in feeding is opened to minimize the stop of a load, and prevent an overload state by providing an under-voltage relay on a change-over switch means for overlap. CONSTITUTION: When a first power source is switched to a second power source in general state, a second power source input solenoid 83 is excited to release an input sprint 51, and the second contacts 7', 8' of the second power source make contact to each other. Since the second kicker 52 of a second cross releasing mechanism is successively operated to open the first contacts 7, 8 of a first power source, both the contacts are mutually overlapped and switched. When the second power source is switched to, on the other hand, by the service interruption or significant voltage reduction of the first power source, a first power source opening solenoid 68 and a solenoid 83 are simultaneously excited by a high-speed operating type undervoltage relay provided on a system.  The contacts 7', 8' are thus inputted at high speed just after the contacts 7, 8 are opened, and the service interruption time of a load is shortened. Further, the second power source after switching has no overload.

Abstract: PURPOSE:To facilitate a finger positioning at the time of collating, to shorten a fingerprint collating time and to improve a collation ratio by providing a displaying means, etc., for correcting a finger position and displaying visibly registered fingerprint data and fingerpring data to be collated. CONSTITUTION:At the time of registering a fingerprint, a finger 1 place at a finger placing stand 2 is image-picked up through a half mirror 3 and a light source 4 by a CCD camera 5 and recorded through a binary circuit 6 to a first memory 9. At the time of collating a fingerprint, first, the finger data from the memory 9 are inputted through a mixing circuit 10 and a driving circuit 11 to a displaying device 12 and visibly displayed as registered fingerprint data. Next, the collated fingerprint data from the camera 5 are inputted through circuits 10 and 11 to a device 12, displayed together with the registered fingerprint data, and when the dislocation of a position is present, the position correction is executed. Namely, the device 12 is watched, the position of the finger 1 is moved so as to match with the position 1 placed at the time of registration and the positioning of the finger at the time of collation can be facilitated. Thus, the fingerprint collating time can be shortened and the collation ratio can be improved.

IPC: G01N25/72
Filed: 1988-10-08
Abstract: PURPOSE:To detect a flow on the internal surface of the exhaust cylinder which is small in inside-outside temperature difference by giving temperature variation to the exhaust cylinder from its internal surface side and then photographing the external surface of the exhaust cylinder by an infrared-ray camera. CONSTITUTION:A heater 4 is installed nearby the bottom part in the exhaust cylinder 1 to heat the gas in the exhaust cylinder 1. The temperature in the exhaust cylinder 1 is raised from the internal surface side with the heated gas. At this time, when there is a flaw such as the floating and falling of a lining material 3 and the deposition of dust on the lining material 3 on the internal surface of the exhaust cylinder 1, the temperature difference of the external surface due to differences in heat conduction characteristics and heat conductivity is increased by raising the temperature from the internal surface side of the exhaust cylinder 1, so that a difference in external surface temperature appears between the flaw part and normal part of the internal surface. Therefore, the flaw on the internal surface can be detected by photographing the external surface of the exhaust cylinder 1 by the camera 7.
