摘要： A touch-sensing apparatus comprises a light transmissive panel, in which sheets of light are propagated by internal reflection between a touch surface and an opposite surface from an incoupling site to an outcoupling site. The touch-sensing apparatus is configured such that objects touching the touch surface cause a local attenuation of at least two sheets of light. A light sensor arrangement is optically connected to the outcoupling site to measure transmitted light energy. A data processor is connected to the light sensor arrangement and configured to execute a touch determination process. The process operates on at least one projection signal which is indicative of a spatial distribution of light within the outcoupling site.

摘要： A device operates on output signals from a light sensor arrangement in a touch-sensing apparatus to determine a position of an object on a touch surface. The apparatus includes a light transmissive panel that defines the touch surface and an opposite surface. A light source arrangement provides sheets of light inside the panel, wherein each sheet comprises light that propagates by internal reflection between the touch surface and the opposite surface from one or more incoupling points to a set of outcoupling points. The light sensor arrangement generates the output signals, which represent light reaching the outcoupling points. The apparatus is configured such that an object touching the touch surface locally attenuates at least two sheets of light. To determine the position, the device identifies, in the output signals, a set of signal profiles originating from said object. The device determines at least part of an attenuated light path across the panel based on each signal profile, and identifies the position of the object on the touch surface based on the thus-determined attenuated light paths. In determining the attenuated light path, the device applies a predetermined width function which is representative of a dependence of signal profile width on distance to the incoupling point due to light scattering caused by at least one of the touch surface and the opposite surface.

摘要： An electronic pen has a force sensor whose electrical resistance varies in accordance with the amount of force applied to the pen stem of the pen. The force sensor is a modular unit with an electrode and a closure, which are mutually arranged in an essentially electrically insulated initial position. The closure, which conveniently is cantilevered on the electrode, is adapted to receive axial forces from the pen stem and thereby to be urged to an activated position in electrical contact with the electrode. The closure is also arranged, on relaxation of the axial forces, to automatically spring from the activated position back to the initial position.

摘要： An apparatus for determining an interaction between an object and a touch surface of a panel. An illumination arrangement introduces light into the panel for propagation by internal reflection between the touch surface and an opposite surface and towards a receiving light detection arrangement. A processor unit is configured to iteratively i) determine, based on the received light, a current light status representing a two-dimensional distribution of light in the panel, ii) determine the interaction with the object as a function of the current light status and a previously updated background status representing a two-dimensional distribution of light in the panel caused by contaminations, and iii) update the background status as a function of the interaction. A method and computer readable medium are also described.

摘要： An apparatus is operated to determine a location of at least one object on a touch surface of a light transmissive panel. An illumination arrangement in the apparatus is operated to introduce beams of radiation into the panel for propagation by internal reflection between the touch surface and the opposite surface, and to sweep each beam along the touch surface within a sensing area. Thereby, the sensing area is illuminated such that an object that touches the touch surface within the sensing area causes at least two beams to be temporarily attenuated. The illumination arrangement is arranged such that each beam, downstream of the sensing area, is swept along one or more elongate outcoupling sites on the panel. At least one light sensor, which is optically coupled to the outcoupling site, is operated to measure the received energy of the beam within the outcoupling site. A data processor is operated to obtain, from the light sensor, an output signal indicative of the received energy of the beam within the outcoupling site as a function of time, and to identify, based on the output signals for the different beams, the location of the object.
