Title: Abnormality determination device for variable operating angle mechanism
Inventor: NAKAGAWA NORIHISA
IPC: F02D41/22
Filed: 2008-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide an abnormality determination device for a variable operating angle mechanism, detecting the abnormality of the variable operating angle mechanism of an internal combustion engine with a high degree of accuracy.  <P>SOLUTION: This abnormality determination device for the variable operating angle mechanism includes the variable operating angle mechanism 12, a control shaft 14, and an actuator moving the control shaft 14. The variable operating angle mechanism 12 enlarges the operating angle of an intake valve 10 arranged in the cylinder of the internal combustion engine when the control shaft 14 is moved in a predetermined direction, and reduces the operating angle of the intake valve 10 when the control shaft 14 is moved in a direction opposite to the predetermined direction. An ECU 50 reads the output value of a rotation sensor 26 as a specific position sensor value and also learns the specific position sensor value to acquire a leaning value, at the timing with the output of a position sensor 28 generated. The ECU 50 compares deviation between the learning value and a newly read specific position sensor value with the total design tolerance to thereby determine the appropriateness of the leaning value.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Image display system and image display method
Inventor: FURUI SHIKI
IPC: G09G5/00
Filed: 2008-02-27
Abstract: <P>PROBLEM TO BE SOLVED: To improve an information transfer speed from a photographing part to a projector, and to simplify information transfer processing.  <P>SOLUTION: A projection image projected to the screen SC is partially distorted caused by a bulge due to wrinkles or slack of a screen SC. From this cause, in an image display system 1000, a remote controller 20 generates distortion correction information 400 to be used for distortion correction processing. A projector 10 applies the distortion correction processing, which provides distortion in a reverse direction to distortion occurring in the projection image, by using the distortion correction information 400 to input image data, and displays the reversely distorted image in a light valve 13. Thereby, the system displays a no-distortion image on the screen SC. Coordinate information of a feature point of which the data volume is small as compared with a photography correction pattern image can be transmitted as distortion correction information. Thereby, the transmission time of information from the remote controller 20 to the projector 10 can be shortened in the distortion correction processing.  <P>COPYRIGHT: (C)2009,JPO&INPIT
