| 20120113003 | DISPLAY SURFACE AND CONTROL DEVICE COMBINED THEREWITH FOR A DATA PROCESSING SYSTEM - 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. | 05-10-2012 |
| 20120038924 | OPTICAL DETECTOR SUITABLE FOR USE IN LIGHT CURTAINS - 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. | 02-16-2012 |
| 20110266423 | DETECTOR SURFACE - A detector surface which is based on optical signals and arranged as a flexible enveloping surface around the body in order to detect whether and where the illuminated indicator strikes the body. The detector surface composed of one or more planar optical fibers, wherein at least one layer of a planar optical fiber has photoluminescent properties, and wherein photodetectors are arranged on the planar optical fiber such that they can decouple light from the optical fiber and detect it. The planar optical fiber is designed as a film made of a transparent polymer having a thickness of 30 to 500 μm and the photodetector is arranged at a distance from all edges of the optical fiber on the optical fiber. | 11-03-2011 |
| 20110115750 | CONTROL SURFACE FOR A DATA PROCESSING SYSTEM - The invention relates to an optical-signal based control surface for a data processing system, said surface being designed as a planar optical fiber, on which photoelectric sensors are provided, the measured signals of which are used to deduce the position of a light signal striking the control surface and said position being associated with a processing mark in the data processing system. A layer having photoluminescent properties is in contact with at least one layer of the planar optical fiber. The light of the light beam shining on the control surface is converted into longer-wave light by way of photoluminescence, said light being coupled into the waveguide, diffusing therein, and being measured by the photoelectric sensors. | 05-19-2011 |
