Patent DE-4232915-A1 (DE)
Inventor: HOHLA KRISTIAN DR
IPC: A61F9/00
Filed: 1992-10-01
Abstract: An apparatus and method for controlling an apparatus for removing tissue from the eye performs various types of corrections using a relatively large beam, but oscillating, or dithering, that being to prevent reinforcing ridges from being formed during the tissue removal process. Further, various types of correction, such as hyperopia and astigmatism correction, are performed using a large beam that is scanned over the area to be ablated using overlapping shots. Further, the epithelium in the area to be treated is removed using an infrared fluorescent dye to dye the epithelium, and then observing the fluorescent patterns from the epithelium area to be removed. Once a certain area is no longer fluorescent after laser shots, smaller shots are then applied, selectively removing the epithelium from the remaining regions. Again, the fluorescence patterns are observed, and the process is repeated until no epithelium remains. At this point, all of the epithelium is removed, and further a map is created of the initial epithelial thickness at each point in the area from which the epithelium was removed.

Patent DE-4315202-A1 (DE)
Inventor: HETTERICH NORBERT DIPL ING
IPC: G06T7/00
Filed: 1993-05-07
Abstract: A device to acquire classification information (38) on the basis of defects (23) or other patterns (12), particularly for sorting profiled boards, has, for inexpensively produced real time operation with high throughput, data reduction, which is based first on selection in each case of a group of adjacent pixels (p) in the sight line (16). The intensity values (i[p]) which are assigned to the selected pixels undergo bit width reduction by a weighting template (30) for unblurred edge detection in the direction of the sight line (16), and in the transport direction (10) which is orthogonal to it, while all intensity contributions of adjacently detected pixels (p) become zero, where a marked intensity jump does not indicate a leading or trailing pattern edge, with subsequent linkage of the resulting edge information with two-level grey value intensity information into pattern information (34), for the representatives of each pixel group of the sight line (16). Horizontally, orthogonally and diagonally adjacent agreeing information in the pattern information (34) of each sequence of two sight lines (16) is individualised by assignment of object numbers (37), and represents, as the result of the fast hardware pre-processing, the classification information (38) for a computer program for pattern classification and for output of sorting class information (40). <IMAGE>

Title: Automatic sun-following arrangement
IPC: F24S50/20
Filed: 1994-06-01
Abstract: The unit comprises two single-axis sun followers. The solar fittings (1, 1') of the two followers are so coupled to one another via a hydraulic force transmission using fluid or gas as work medium that when the solar fitting of one of the two followers executes a movement corresp. to the sun position, the solar fitting of the other follower carries out a complementary movement.

Patent DE-4421540-A1 (DE)
Title: Starter device for vehicles
Inventor: ARAKI TAKESHI
IPC: F02N11/08
Filed: 1994-06-20
Abstract: A starter device is provided which can prevent damage to the starter unit even if a starting current which is conducted to the starter unit is not interrupted owing to switching problems etc. A main storage device is charged by a device in order to produce power and conducts electricity to electric loads in a vehicle and to a secondary storage device. A starter switch conducts the charge current from the main storage device to the secondary storage device while starting is not taking place, as a result of which the secondary storage device, which is specifically designed to drive the starter unit, stores the power which is smaller than that which is capable of causing damage, such as for example burning, at the starter unit, even if the current is continuously discharged to the starter unit but is greater than that which is required for any starting under normal conditions. The starter switch discharges the power which is stored in the secondary storage unit to a coil of an ignition switch of the starter unit in order to close the ignition switch as a result of which the starting power is conducted from the main storage unit to the starter motor of the starter unit.

Title: Frequency regulating method for an invertor, and a device for this purpose
Inventor: ENDO TSUNEHIRO
IPC: H02P23/16
Filed: 1994-07-19
Abstract: The invention is based on the object of producing a frequency-regulating invertor which is robust against interruptions and prevents overcurrent and overvoltage by frequency regulation of a motor. This has been implemented as follows: - produce an acceleration or deceleration rate from the output signal of a fuzzy-logic regulating unit which records the differences between limit values and measured values and their changes; - activates a regulator for acceleration times, which regulator automatically produces an acceleration rate which keeps the current in the vicinity of the limit value, having a part for normal acceleration which sets the predetermined acceleration rate; - activate a regulator for deceleration times which automatically produces a deceleration rate which keeps the current and the voltage in the vicinity of their limit values, having a part for normal decleration which sets the predetermined deceleration rate; and - activates a regulating part for steady-state operation, which automatically determines the acceleration rate or deceleration rate which keeps the current in the vicinity of the limit value; - it being possible for the operator to select the two regulating parts for automatic and normal operation. This results in features like the following being achieved: interruption-free operation, changes in the current and the voltage being taken account of; the option for acceleration or deceleration operation without presetting or setting the acceleration or ...
