  • Patent number: 10724920
    Abstract: The invention describes a method of analyzing a light distribution of a vehicle headlight. The method determines a cutoff line based on a brightness distribution within a column of an image of the light distribution, the column being perpendicular to a horizon in the image. The method compares the cutoff line with a reference cutoff line and uses the deviations revealed by such comparison to attribute a reduced quality of the light distribution to a particular one of several possible causes. The invention further describes a vehicle headlight analyzer which is arranged to perform the method. The invention finally describes a corresponding computer program product comprising code for executing the method on a processing device.

    Abstract: A photoelectric sensor uses a selective pulse detection technique and associated synchronization techniques to improve the quality of pulse detection, the operating range of the sensor, and the sensor's immunity to noise. These improvements also yield faster sensor response times and reduce the design cycle time. A modulated light beam emitted by the sensor's emitter comprises multiple pulse periods, with a pulse being transmitted within each period. The pulses are positioned within their respective periods at a defined offset time relative to the start of the periods, where the offset time can vary between periods according to a defined pattern. The receiver can selectively sample the signal based on synchronization information to determine whether the received signal contains the emitted pulse pattern. Through-beam sensor embodiments can generate the synchronization information internally based on an analysis of the analog signal corresponding to the modulated signal.

  • Patent number: 9170170
    Abstract: In order to determine the focus position of a laser beam (60, 60a) in an ophthalmological laser projection system (1), at least one measurement marking (3) applied to a reference area (20) is passed over by means of the laser beam (60, 60a) along a scanning path. A measurement signal created by passing over the measurement marking (3) is captured. Time values from at least one signal edge created in the measurement signal when passing over edges of the measurement marking (3) are determined and the focus position is established on the basis of the time values. By scanning defined measurement markings (3) and establishing time values of signal edges created when edges of the measurement marking (3) are passed over, it is possible to determine the focus position of the laser beam (60, 60a) without focusing movements being required for this during the measurement.

  • Patent number: 9124451
    Abstract: A radio receiving apparatus according to the present invention receives a preamble signal through one frequency band and also detects a periodic symbol timing in a receiving period of a part of a symbol that composes the preamble signal. A frequency correction circuit includes a generating unit, a detecting unit, and a correction unit. The generating unit generates a detection window of a predetermined time width including each of a first and a second symbol timing that are previously determined among the periodic symbol timings in the receiving period of a remaining symbol that composes the preamble signal. The detecting unit sequentially receives a correlation value between the preamble signal and a reference signal and detects a maximum value from the correlation value input during a period when the detection window is opened. The correction unit corrects a frequency deviation of the one frequency band based on the maximum value.
