摘要： Method for determining the position of an element (3) which is displaceable relative to a stator (2). The stator (2) comprises at least one transducer (4-7). An electric signal is applied to said transducer (4-7) due to which a wave is generated in the surface of the stator (2). At least part of said wave is reflected to the transducer (4-7) by the displaceable element (3). By means of a processor the position of the displaceable element (3) relative to the stator (2) is determined from the reflected wave.

摘要： In an apparatus comprising an optical keyboard (140) and an optical input device (182,186) controlled by a moving object and wherein the input device comprises at least one diode laser and photo diode (182) for supplying at least one measuring beam (184) to a device window (186) and for receiving radiation reflected by the object placed on the window, the input device is integrated in the keyboard such that the measuring beam (184) is guided via the positions of the keys (125) to the window (186). In this way the optical the keyboard is substantially simplified and the reliability of the output signal of the input device increased.

摘要： In an optical input device based on movement of an object (15) and the device relative to each other and which comprising at least one optical sensor unit including a laser (3) having a laser cavity for generating a measuring beam (13), converging means (50) for converging the measuring beam in an action plane and for converging measuring beam radiation reflected by the object in the laser cavity to generate a self-mixing effect in the laser and measuring means for measuring the result of the self-mixing effect, which effect is determined by said movement, the converging means (50) is adapted to provide a self-mixing effect that is smaller than a possible maximum but larger than a detection threshold for an extended range of distances (AZ) between the object and the device. This allows obtaining the required self- mixing effect in an extended range of distances between the object and the device.
