Patent EP-0374290-A1 (EP)
Inventor: SCHEUCKEN HEINRICH DIPL-ING
IPC: B61F5/38
Filed: 1988-12-21
Abstract: The invention relates to a rail vehicle, which comprises a predeterminable number of individual wheels on both sides along the longitudinal axis of the vehicle, which wheels can be swivelled by steering. A steering free from tracking errors of each individual wheel in all curve regions is achieved by a rail-run measuring device (14-17) being provided, which measures the deviation of a vehicle axis (13) from the run of the rails (6, 7) and which generates dependently of measured deviations a steering signal (g1-g4) for each individual wheel (2-5) independently from other wheels. <IMAGE>

Abstract: The invention relates to a radar system comprising a transmitter with a periodically tunable HF-transmitter tube, as a magnetron with rotating tuning body, and a receiver with a mixing stage, in which echo pulses caused by transmitted radar pulses are mixed with the output signal from a local oscillator, whose frequency can be controlled. During transmission the tuning frequency of the transmitter tube is varied periodically and in an interval before triggering the local oscillator is "slaved" to the transmitter tube, so that the local oscillator frequency follows the variations in the tuning frequency. In the triggering moment the local oscillator is locked in frequency to the value prevailing in the triggering moment. According to the invention this system is combined with a frequency predicting circuit, which mainly consists of a compara­tor. In this comparator the control signal of the local oscillator, which due to the said "slaving" represents the instantaneous tuning frequency, is compared with a reference signal. The transmitter tube is triggered when the two compared signals are in a given relationship to each other, e.g. equal. Hereby, the transmitter tube is brought to produce a radar pulse having a predicted frequency, which is mainly determined by the said reference signal.

Abstract: A method of parsing a sentence into sentence parts to be described with functional indications, by means of lexicalized word units, in accordance with the following steps:
     a. Determining, for each word unit and for each constituent, the func­tional word category within the constituent or a new constituent;   b. Describing, for each constituent, a step relating to closure of the constituent, and allocating a functional label to that constituent;   c. Testing the current constituent against rules relating to the con­text of the words and/or subsidiary constituents, and revaluation of a probability factor allocated to the sentence representation, and the selection of each sentence representation having a probabi­lity factor above a certain threshold value.    A grammatically incorrect sentence already parsed can be corrected by selecting the grammatically incorrect constituent within the sentence and then change of this constituent by reference to regu­lations based on the mentioned rules.

IPC: G06F9/45
Filed: 1989-06-22
Abstract: A compiler for generating code for enabling multiple processors to process programs in parallel. The code enables the multiple processor system to operate in the following manner: one interation of an outer loop in a set of nested loops is assigned to each processor. If the outer loop contains more iterations than processor in the system, the processors are initially assigned an earlier iteration, and the remaining iterations are assigned to the processor one as they finish their earlier iterations. Each processor runs the inner loop iterations serially. In order to enforce dependencies in the loops, each processor reports its progress in its iterations of the inner loop to the processor executing the succeeding outer loop iteration and the waits until the processor computing the preceding outer loop is ahead or behind in processing its inner loop iteration by an amount which guarantees that dependencies will be enforced.
