Title: Abnormal message detection processor
Inventor: ONISHI SHINGO
IPC: G06F11/00
Filed: 1990-07-13
Abstract: PURPOSE:To automatically detect an abnormal message and to produce a warning by performing the comparison of character strings between an input message and each message of an example sentence information part excluding a variable pat designated by a variable part designation information part and performing a prescribed output operation according to the presence or absence of a message of the example sentence information part that is coincident with the input message. CONSTITUTION:The necessary number of examples of a series of message groups of the necessary tasks are prepared at an example sentence information part 1. A variable part designation information part 2 designates the position of a part that may possibly be changed at each output of the date, etc., of the message as the position of a variable part. Then the message outputted in a relevant task is given to an abnormality detection part 3 as an input message. Thus the part 3 checks whether any example sentence is coincidence with the input message or not excluding the variable part. If so, a message showing a normal state is decided. If not, a message showing the abnormality is outputted. Thus it is possible to automatically detect an abnormal message out of many messages and to produce a warning.

Abstract: PURPOSE:To shorten the processing time by image-processing the output of two element for one-dimensional image pickup that are kept a specified distance apart from a reference origin of an object and have a specified tilt against a horizontal axis, respectively, and calculating a correction quantity against the reference position. CONSTITUTION:An image processor receives the input signals from one- dimensional image pickup elements 2A and 2B, and calculates respective intersections QA.QB and TA.TB between an object 3 and the elements 2A and 2B as a distance from origins OA.OB. A correction tilt quantity DELTAtheta for initial position 3B against the reference position 3A of the object 3 can be calculated because the element 2A and 2B tilt by thetaL against X axis.

Since the intermediate position 3C is parallel to the reference position 3A, the object 3 can be set on the reference 3A from the intermediate position 3C by slightly moving it by correction shift quantities DELTAx and DELTAy in the X and Y directions respectively.
