Filed: 2008-12-04
Abstract: <P>PROBLEM TO BE SOLVED: To highly accurately diagnose sensitivity abnormality of a cylinder pressure sensor.  <P>SOLUTION: In this abnormality diagnostic device, a total heat production parameter ΔPV<SP>κ</SP>correlating with the total heat production generated by one combustion of an internal combustion engine is normalized by a fuel amount τ to calculate a combustion parameter H corresponding to a low heat production q<SB>fuel</SB>of the fuel, and an abnormality in the cylinder pressure sensor is diagnosed based on the combustion parameter H and the low heat production q<SB>fuel</SB>. The expression of ΔPV<SP>κ</SP>=P(θ<SB>2</SB>)V(θ<SB>2</SB>)<SP>κ</SP>-P(θ<SB>1</SB>)V(θ<SB>1</SB>)<SP>κ</SP>is satisfied, wherein the P(θ<SB>1</SB>) and P(θ<SB>2</SB>) are cylinder pressure detected by the cylinder pressure sensor at predetermined crank angles of θ<SB>1</SB>, θ<SB>2</SB>before and after the combustion, the V(θ<SB>1</SB>) and V(θ<SB>2</SB>) are cylinder capacities at the crank angles θ<SB>1</SB>, θ<SB>2</SB>, and the κ is a predetermined ratio of specific heat. When the sensitivity of the cylinder pressure sensor is abnormal, the sensitivity abnormality of the cylinder pressure sensor is diagnosed, by using a fact that a value of a combustion parameter H is not approximately equal to a value of the low heat production q<SB>fuel</SB>.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Authentication device
Inventor: NISHIMURA OSAMU
IPC: G06F21/32
Filed: 2008-12-10
Abstract: <P>PROBLEM TO BE SOLVED: To prevent causing damage to authentication history data or file systems which may occur at power supply cutoff when performing writing from SRAM as a temporary buffer of the authentication history data in a management section to a CF memory as a nonvolatile memory in an authentication device where an authentication section performing authentication processes and the management section storing authentication history are integrated.  <P>SOLUTION: The authentication section 220, which detects a power failure, transmits the low voltage to the management section 210 when power is supplied from a secondary battery and the supplied power is below a predetermined threshold. Then, the control section 210 instructs the authentication section 220 to stop transmission of the authentication history. Thereby, writing from the SRAM to the CF memory card is restrained since the authorization history data is not increased in the management section 210.  <P>COPYRIGHT: (C)2010,JPO&INPIT
