Patent DE-19713785-A1 (DE)
Title: Method to determine specified liquid level
Inventor: VELHAGEN KARL-HEINZ PROF DR
IPC: G01F23/292
Filed: 1997-04-03
Abstract: The method involves using a laser light barrier. A vessel with transparent liquid is located in the beam path of the laser beam. The laser beam (1) is interrupted by the liquid at the incident (2) and reflective (3) axes. The laser beam is totally reflected at the liquid-air interface by a determined region of the liquid level. Preferably, the optical and mechanical axes of the undisturbed light barrier coincide. The light barrier is only interrupted by the deflection of the laser beam at the incidence axis for the liquid. The interruption of the beam barrier may be excluded by lowering liquid below the height of the incidence axis to the liquid.

Abstract: Form, shape and function of single parts and figures are presented, stabilised and connected up by means of balls with tapped round holes (1,2) and bars (18,24) externally threaded (18) to fit into the holes and externally threaded parts devoid of bars. Balls and oval-section rounds of differing diameter are variously arranged in internally tapped round holes (1,2). Some shapes have continuous hollow cylindrical holes tapped both sides to vary the nodal arrangements of the system as a whole. Bars (18) of differing length and thickness in round and/or cornered section are in turn externally threaded at the bar ends to fit into the holes (1,2) in the balls and connect up the system at optional spacing. The outside threads (22,24) come in various lengths for the round holes (1,2) in the balls and shoe or foot shapes come in flat or angled form (2,28). All the parts of the system are threaded inside and/or outside to fit into the ball holes and all parts can rotate relative to one another normal to the screwing sense in optional directions. The board or baseplate is a surface-structured plastics floor segment as a raster with or without diagonal or right angle cutting lines, or again holed above and fitted at the sides with round holes for the plug-up pins used to join up the boards.

Patent DE-19728509-A1 (DE)
Title: Method of measuring railway vehicle wheel profiles
Inventor: SCHNEIDER FRIEDHELM DR ING
IPC: G01B11/25
Filed: 1997-07-03
Abstract: The method involves using a light interception technique. An illumination device mounted adjacent to the rail projects a light strip onto the wheel profile. An image acquisition unit next to the rail images the illuminated part of the profile and the contour of the profile is determined from the image of the light strip. The method is implemented without interrupting the standard rail to replace it with an auxiliary rail. The profile contour may be transformed into the co-ordinates of the radial direction of the wheel using the distance from the plane of the light intersection to the wheel contact point, the angle of the plane to the rail and the height of the intersection point of this plane with the wheel.

Inventor: BONK ROLAND DIPL ING
IPC: H04N5/217
Filed: 1997-08-11
Abstract: The invention relates to a method for compensating the dark current of an electronic sensor having several pixels each with individual dark current behaviour. According to said method a radiation originating from a radiation source (3) and designed to generate an image signal (BS) is pointed at a detector unit (4) containing the sensor. An image with different synchronization speed (v) (integration time) is established by reading the detector signal (S) present in the sensor pixels. The method is characterized in that before the start or after the end of the image recording in the presence radiation the sensor is read in the absence of radiation at at least two different synchronization speeds (v1, v2) in such a way that at least two dark current signals (DS1, DS2) are captured for every pixel, in that the read dark current signals (DS1, DS2) are then used to calculate a dark current value (DW) of individual sensor pixels in relation to the synchronization speed (v), and in that on the basis of the dark current value assigned to each pixel, the detector signal (S) superimposed by the dark current signal is corrected so as to determine the image value (BW).

Title: Method of controlling automatic transmission of a wheel loader
Inventor: AUMANN BERND
IPC: F16H61/02
Filed: 1998-02-20
Abstract: An electronic transmission controller activates the automatic mode of the transmission at system start. If the gear lever remains in the neutral position, the transmission selects an optimal gear for the driving conditions within a programmed range. A lower gear not in the programmed range is selected if an additional load is detected at the torque converter or accelerator pedal. The method involves using an electronic transmission controller which activates the automatic mode of the transmission at system start and if the gear lever remains in the neutral position for a defined period, so that preselecting the forward or reverse range causes a start-off gear to be selected, the transmission then selects an optimal gear for the driving conditions within a programmed range. A lower gear not in the programmed range is selected if an additional load is detected at the torque converter or accelerator pedal. When the additional load is not present the transmission changes back up into the normal programmed range.
