A primary object of the present invention is to extract a difference in shading of a blood vessel image in a picked up image as information to be used for authentication, and to acquire a larger number of pieces of biometric information from one image. An individual authentication device to be used to authenticate an individual using feature information of a vascular pattern acquired from a living body includes an imaging unit that images a region of the living body serving as an object of authentication, and an arithmetic unit that acquires the picked up image as an authentication image. The arithmetic unit extracts a vascular pattern from the authentication image, and acquires a degree of shading of the vascular pattern as the feature information.

Respective positive terminal electric potentials of exhaust gas sensors are sequentially selectively inputted to an analog input terminal of a multi-channel AD converter through a multiplexer. An offset voltage is applied to respective negative terminals of the exhaust gas sensors. This offset voltage is inputted to another input terminal of the multi-channel AD converter. A microprocessor detects a generating voltage of the exhaust gas sensors by the difference between a digital converting value of the positive terminal electric potential and a digital converting value of the negative terminal electric potential. The microprocessor also individually judges that each of the digital converting values is excessively small and excessively large. Thus, the microprocessor judges the existence of ground, sky short circuit and disconnection abnormalities of the negative terminal and the positive terminal.

摘要:
A circuit board is hermetically-sealed and housed in a steel case that is composed of a metal base and a metal cover, the cover disposed opposite to a first board surface has a tall flat portion disposed opposite to a connector housing and a short flat portion disposed opposite to a heating component, and the heat generated from the heating component is directly transferred to a heat transfer base portion of the base via a heat transfer mechanism and a heat transfer filling material. Surface finishing in which the coefficients of heat radiation are mutually 0.7 to 1.0 is applied to the surface of the heating component and the opposite inner surface of the cover, and radiation and heat transfer are efficiently performed to the short flat portion of the cover.
