Patent DE-19703758-A1 (DE)
Title: Thermal protection device e.g. for small inner spaces of housings
Inventor: TAKEDA HIDEAKI
IPC: H01H1/50
Filed: 1997-01-24
Abstract: Thermal protection device has a fixed metallic strip (4) move ble contact strip (3) bimetallic strip (2) heating element (1) contacts (T1) to the heating element (1) and (C1,C2) between the fixed and movable strips. Once a fixed temperature is exceeded the bimetallic strip bends, breaking the electrical circuit (and hence stops any heating mechanism) by moving the movable strip with it. The heating element (1) is of a weakly elastic, flexible material with a resistor enclosed within. As the material is elastic it flexes with the metallic strip, and also maintains close thermal contact with the strip. Once the electrical contact between the two strips is broken a second circuit provides a small heating current to the heater and hence the bimetallic strip.

Title: Spatial transformation determination method for X-ray imaging
Inventor: WEESE JUERGEN DR
IPC: G06T11/00
Filed: 1997-02-14
Abstract: The method provides the spatial transformation between an object image represented by a 3-dimensional data set and the object (3) itself, by providing a pseudo projection image (Ip) representing a projection of the image in a 2-dimensional region with defined projection parameters. The degree of similarity between the pseudo projection image and the X-ray image of the object is determined for selection of the spatial transformation providing the best match. A partial volume of the examined area is selected before provision of the pseudo projection image, with the latter limited to the selected partial volume, with determination of the degree of similarity by comparing similar structures in the X-ray image and the pseudo projection image.

Title: Reading of bar code information
Inventor: REICHENBACH JUERGEN
IPC: G06K7/14
Filed: 1997-03-21
Abstract: The reading of the bar code is based on the fact that the bar code reader emits a scanning beam that is moved through an arc as the object on which the bar code is printed is moved in a specific direction (6).  The bar code (7) can be set at an angle to the direction of the scanning lines (5) of different sensing elements. This produces code segments for each of the bar code lines and these can be processed to identify the code.
