Title: Copy controlling using coordinate measuring probe with rotary table
Inventor: FUJIMAKI SHIGERU
IPC: G01B21/00
Filed: 1990-08-29
Abstract: The three dimensional shape of a workpiece 14 to be copied is measured by rotating it on a turntable 10 against a probe 16. Initially, the workpiece is set on the turntable and its axis determined to prepare a coordinate system. As the workpiece rotates, the probe position is controlled to maintain the probe in the same angular relationship with the centre axis of the workpiece. This is done by calculating a probe speed vector which depends on the shape of the workpiece in the vicinity of the probe and on the workpiece rotation. A turntable rotation signal is calculated at the same time to control rotation speed. It is stated that this measurement method is used in conjunction with a static three axis copy control in controlling the copy process to keep the probe of a constant angle to the workpiece axis. <IMAGE>

Title: Testing bending strain and energy absorption of beams
Inventor: SATO SHOJI
IPC: G01M5/00
Filed: 1990-12-24
Abstract: A method of non-destructive inspection for elongate members e.g. resinous automotive bumper beams comprises applying flexural load to the center of a beam by a pressing jig with both ends of the beam pivotably supported to gradually bend the beam, measuring or determining the bending strain and energy absorption of the beam, said energy absorption being calculated from said bending strain and flexural load, and accepting the beam only when the energy absorption reaches a control value in advance, and the bending strain is at most a control value set in advance. The control values of the energy absorption and bending strain are determined by correcting the values of energy absorption and bending strain reached upon destruction of a beam, in a standard destructive test. Those corrections are performed on the basis of the correlations between a plurality of data as to the energy absorption and bending strain in the standard destructive test and in a destructive test with the beam ends pivotally supported.

Title: Vehicle accident prevention and recording system
Inventor: SHYU JIA-MING
IPC: B60R16/02
Filed: 1992-06-10
Abstract: The system monitors and records the operation of the vehicle, driving status and the outside environment safeguards the vehicle against traffic accidents by warning the driver in the nick of time and correcting the operation of the vehicle automatically. After an accident occurs, the ins and outs of the occurrence, by means of a computer device, can be retrieved, played back and analysed based on the aforesaid recorded information. The record can be used in the drivers' training courses, or as driving reference; be of benefit to the insured and the insurance companies; be used as reference to assist the official judgment of this accident. Most of all, due to the function of automatic monitoring and recording, this device will give alarms as the accident occurs which can prevent its following vehicles from colliding with each other; also, the traffic lanes, after the accident occurs, can be restored to the original condition quickly, since the device has already recorded most of the required information which can reduce the argument among the drivers involved and help the patrolman handle this incident quickly. <IMAGE>
