  • Patent number: 9639180
    Abstract: A computer system that includes a data-processing unit, a touch-sensitive, position-resolving input surface in data communication with the data-processing unit, and a freely movable input device, by which the input surface is to be touched for the purpose of inputting into the data-processing unit. The freely movable input device is a computer mouse, which is in data communication with the data-processing unit. With comparatively low sensor complexity, inter alia, both the absolute position of the computer mouse and also subtle position changes of the computer mouse can therefore be very easily detected by the data-processing unit.

  • Patent number: 9405384
    Abstract: A computer system, including data-processing equipment and a freely movable input device, wherein the input device contains at least one position change sensor from which information can be sent to the data-processing equipment and wherein the data-processing equipment can also capture information about the absolute position of the input device. Information about the absolute position of the input device can be captured by the data-processing equipment as a result of the fact that the data-processing equipment is in data communication with a light-sensitive, position-sensitive input surface and the input device emits a light beam, the point of incidence of which on the input surface can be detected by the latter.

  • Patent number: 9075156
    Abstract: A light curtain for the optical detection of shading objects in an area to be monitored, wherein the area to be monitored is repeatedly swept over by a collimated light beam of variable direction. The power of the light crossing the area is measured, shadow boundaries, position and size of a shading object are deduced by an evaluating control from the temporal profile of the measured power with knowledge of the temporal profile of the direction of the light beam. An optical detector area embodied as a planar optical waveguide is arranged along the edge of the area to be monitored, photoluminescent particles being integrated into said optical detector area and one or more photoelectric sensors being fitted to the optical detector area. Using the light curtain, shading objects can be detected with very good resolution, the light curtain can be robust and can have a low production cost.

  • Publication number: 20140022170
    Abstract: A light curtain having a light source which emits a light beam which propagates in an area to be monitored by the light curtain and then strikes an optical detector surface. The area to be monitored is arranged in the vicinity of a translucent disc and is oriented parallel to the latter. The light source and detector surface are arranged on that side of the disc which faces away from the area to be monitored. The path of the light beam from the light source to the detector surface runs twice through the plane of the disc and via two mirrors arranged on the edge of the area to be monitored.

  • Publication number: 20130063408
    Abstract: A projection device and to a method for operating the device. The projection device includes a projector, a projection surface, and a data processing system, wherein information about the image on the projection surface is transferred to the data processing system and wherein the data processing system controls the projector. The projection surface is designed as a planar optical waveguide, in which photoluminescent particles are integrated and on which a plurality of photoelectric sensors are attached, which are able to couple light out of the waveguide mode and to thereby generate an electrical signal, the strength of which depends on the intensity of the light coupled out at the photodetector.

  • Publication number: 20120113003
    Abstract: A combined display surface and a control device for a data processing system, wherein the position of a light beam hitting the display surface is measured and the measured result is used by the data processing system as a basis for determining a cursor position on the display surface. Several strip-shaped optical position detectors are arranged along the edge of the display surface, the measured signals of which are fed into the data processing system. The cross-sectional shape of the indicator beam is formed by several lines which protrude both the display surface and the position detectors arranged thereon. The optical position detectors are formed by a layered structure made of organic material.

  • Publication number: 20120038924
    Abstract: A planar detector for use in light curtains, which generates electric signals as a function of absorbed light and is provided with a plurality of tapping points for the generated signals. The magnitude of the signals at the respective tapping points is dependent on their distance to the partial surfaces where the light is absorbed. As a function of the magnitude ratios between the signals at several tapping points, the distance ratios of the respective tapping points to those partial surfaces, where the light is absorbed, can be calculated. The detector is configured as a flexible layered structure made of organic material. The tapping points are disposed at a distance from the edges of the layered structure. Electric connection lines to the tapping points are connected along their longitudinal extension to the layered structure of the detector.

  • Publication number: 20030198302
    Abstract: A bit slicer circuit and method detect the peak of the differential slope in a demodulated data signal received via a wireless data system, so that bit slicing can be insensitive to DC fluctuations. This is accomplished by detecting when the demodulated signal transitions by more than a predetermined threshold value Vth during each symbol period, and determining the polarity of a detected transition. A latch is set and a logic “1”, is output when the polarity of a detected transition is negative; the latch is reset and a logic “0” is output when the polarity is positive.

  • Publication number: 20030198311
    Abstract: A fractional-N frequency synthesizer is based on a PLL which employs a multi-phase VCO and a multi-phase frequency divider to provide a desired fractional-N divider ratio. The multi-phase frequency divider includes a multi-modulus divider which divides a VCO output waveform with a division ratio that varies in response to a modulus control signal. The divided output is delayed to produce a plurality of outputs, each of which has a respective phase that corresponds with the phase of a respective VCO output. A phase selector provides a selected one of the outputs to the PLL's phase detector in response to a phase control signal such that the multi-phase frequency divider provides a fractional-N division ratio. To reduce fractional spurs, a modulator randomizes the modulus and phase control signals, which serves to randomize and thereby reduce phase mismatch error which might otherwise be present in the frequency synthesizer's output.
