Abstract: This invention relates to a foldable vehicle comprising at least three wheels which of one wheel is a steering wheel, a steering handle, a frame connected with the steering element and having at least one standing surface. Upon folding the frame will be movable with respect to the steering handle to statically fit together in a compact manner Hereby a practical and efficient vehicle for personal transportation and commuting is created.

Abstract: A method and a system for determining the position of a radiation emitter, which radiation emitter may be an actively radiation emitting stylus, pen, pointer, or the like or may be a passive, radiation scattering/reflecting/diffusing element, such as a pen, pointer, or a finger of an operator. The radiation from the emitter is reflected from that position toward the detector by a reflecting element providing multiple intensity spots on the detector providing sufficient information for determining the position. From the output of the detector, the position of the radiation emitter is determined.

Abstract: A method and system for determining the position of a radiation scattering/reflecting element, where the radiation emitter is provided at a surface of a radiation transmissive element an on which radiation is incident. This incident radiation is scattered/diffused/reflected by the scattering/reflecting element and guided by the transmissive element toward a detector able to determine the position of the element.

Abstract: A system and a method for using a single 2-D-radiation detector for simultaneously detecting radiation from a plurality of independent applications and for outputting a signal from which information relating to each application may be derived. The radiation from each application is provided to individuals parts of the sensor.

Abstract: A method and a system, such as a touch pad, for determining the position of a radiation emitter, which radiation emitter may be an actively radiation emitting stylus, pen, pointer, or the like or may be a passive, radiation scattering/reflecting/diffusing element, such as a pen, pointer, or a finger of an operator. The radiation is modulated by a bar code element and provided onto an at least one-dimensional detector. From the output of the detector, the position of the radiation emitter is determined. This system may be used as a standard touch pad or for determining the position of emitters external thereto, such as a marker used on a wall or black/white board or may be used with “internal” positions such as a touch pad.

Abstract: A touch pad or touch screen having a light transmissive means having a surface receiving light, such as from a stylus or pen emitting light at a point thereof, transmitting the light along the surface and determining the position at the surface receiving the light. This touch pad may be made of a hard material. A flexible element is provided on top of the surface and light transmitted into the flexible element. Depression of the element directs light into the surface for detection. A keyboard may be positioned on the surface of flexible element. Lenses or mirrors may be provided for receiving light from outside the pad/screen for determining a position also outside the pad on a working surface, such as a white board, a desk, or a newspaper.
