Title: Simulation of image persistence on display screen for direction finding - updating sequence of digitally-generated images by replacing oldest with newest, and reducing brightness of each image with age when displaying on dark background
Inventor: BLOHM GUNDULA DIPL ING
IPC: G09G5/02
Filed: 1992-10-23
Abstract: The direction finding system simulates persistence on a screen for an image that is produced by a number of sequential images on the screen. As each new image is added, the oldest one is cancelled. Colour and grey tones may be used for representations. The colours and grey tones are stored in a table in memory together with the background value. Each image to be displayed is defined by points held in a video memory, with the table accessed to provide the colours. ADVANTAGE - Provides real time processing for large quantities of data.

Title: Method for the production of door impact beams for motor vehicles
Inventor: BOEHMER WERNER
IPC: B23K26/364
Filed: 1993-03-06
Abstract: The method uses a laser beam (LS) in order to be able to divide up a tubular blank (1) into a plurality of door impact beams (2) virtually without the loss of any material. For this purpose, the laser beam (LS) is guided in such a manner with a plurality of partial cuts (33, 6, 7, 8, 34) through the material of the tubular blank (1) that two channel-like end sections (9) are produced. The partial cuts (33, 6, 7, 8, 34) can run perpendicularly with the inclusion of partial cuts (6, 8) in the shape of a section of a circle, or else can run at an angle with respect to one another. In any case, the laser beam (LS) is guided into the material of the tubular blank (1), and also removed therefrom, transversely with respect to the vertical plane (E1-E1) running through the longitudinal axis (4) of the tubular blank (1). Between these two entry and exit cuts (33, 34) running in the planes (E-E and E2-E2) partial cuts can be carried out in the longitudinal axis (4) parallel to the longitudinal axis (4) or diagonally to the longitudinal axis (4). <IMAGE>

Title: Multivariable nursing bed
Inventor: FLUEGEL BERND DR RER NAT
IPC: A61G7/015
Filed: 1993-05-24
Abstract: There is proposed a multivariable nursing bed which optimally assists nursing of patients with a variety of movement impediments.

Title: Device for measuring the sag of a conductor clad with an insulating layer in a vulcanised (cured) tube
Inventor: WENIGER KLAUS
IPC: G01B7/31
Filed: 1993-09-22
Abstract: A device is described for measuring the sag of a conductor clad with an insulating layer. In this case, a transmitter is used to impress an alternating current inductively into the conductor located in the vulcanised tube, and the sag of the conductor is measured with the aid of two magnetic measuring sensors which output corresponding position signals. The position signals are fed to a signal processing and signal evaluation circuit, which has, in particular, a sample-and-hold circuit for obtaining fixed signals, a central unit with a memory, and a summing element (summator). The central unit calculates an average value from a specific number of fixed signals, and the average value obtained is subjected to frequency response analysis. It is possible as a result for disturbing influences caused by heaters, other machine couplings (interferences), etc. to be largely removed in noisy signals. <IMAGE>

Title: Circuit for monitoring a supply voltage
Inventor: CHAPMAN MICHAEL
IPC: G01R31/30
Filed: 1993-10-08
Abstract: A circuit is proposed for monitoring the supply voltage of an integrated circuit with a Schmitt trigger, which circuit is used for establishing a drop in the supply voltage below a minimum value or the exceeding of a maximum voltage. The supply voltage is converted into a proportional voltage with the aid of the voltage divider. If the proportional voltage lies within the predetermined value range, the output of the Schmitt trigger remains at a constant voltage level. If, however, this value range is departed from, the output of the Schmitt trigger switches over to a second voltage level. With the aid of a resistor and a capacitor, supply of the Schmitt trigger with sufficient voltage is ensured even in the event of a drop in the supply voltage. <IMAGE>
