摘要： A method of reading an indicia, for example a bar code, comprising areas of differing light reflectivity comprises producing an electrical signal representative of light reflected from the indicia and selectively sampling the signal at a rate well below the Nyquist rate. The sample points are not uniform, and are chosen to represent key features in the signal. An attempt is then made to decode the indicia, using the samples. If the decode is unsuccessful, the samples which have been collected are analyzed to provide information on the extent to which they represent true data corresponding to the indicia, and the extent to which they present noise. Signal collection and/or processing and/or sampling is then adjusted and the process is repeated. The continual feed-back of information related to the scanning environment allows more aggressive decoding techniques to be used.

摘要： A laser wand for reading optically encoded indicia has a wand shaped housing for housing a light emitter which for emits a focussed laser light beam having a fixed focal point beyond which said light beam diverges. The light beam is directed towards a surface on which the indicia is disposed. A spacer is also provided for alternatively defining different separation distances between the light emitter and indicia. At a first separation distance, the light beam forms a sensing spot of a first size on the surface on which the indicia is disposed. This sensing spot is effective for reading indicia having a first physical characteristic. At a second separation distance, the light beam forms a sensing spot of a second size, which is larger than the first size, on the surface on which the indicia is disposed. This later sensing spot is effective for reading indicia having a second physical characteristic different from the first physical characteristic. For example, indicia having the first physical characteristic may be of a higher density than indicia having the second physical characteristic.

摘要： A portable terminal has a housing with a motion detector housed therein. Movement of the housing from a a rest position is detected by sensing the motion of a coil or magnet located within the housing. A controller activates circuitry within the housing responsive to the detected movement. The terminal may include a touch sensitive display, on a flat front surface of the housing. A light emitter and an optical detector may also be disposed within the housing. Preferably, the terminal also houses a sensor for sensing different specific positional orientations of the terminal and activating or deactivating terminal functions depending on the sensed orientation.

摘要： An electronic stylus, for use with a computer having a digitizer, has a light emitter for emitting light to illuminate optically encoded information. A photodetector senses light reflected from the illuminated optically encoded information and produced an electrical signal representative of the optically encoded information. Stylus electronics provide positional input data by contacting a digitizer tablet with the stylus. The stylus housing contains the light emitter, photodetector and stylus electronics. A tip at a fore end of the housing is adapted for contact with the digitizer tablet and the light is emitted from other than the fore end of the housing.

摘要： An optical scanner for reading optically encoded indicia such as a bar code is contained within the same housing as a mouse-type position sensing device. The position sensing portion comprises a track ball extending through a lower opening in the housing and associated movement detection electronics. As the housing is moved by the user across a flat surface, the track ball engages the surface and the associated electronics detect the extent of the movement of the device across the surface. Conveniently located keys allow the user to activate a switch by clicking, and this data along with positional data detected by the track ball electronics is provided as input to an associated computer. The device comprises an optical scanner in the form of a laser beam source, means for oscillating the laser beam so as to produce a scanning beam directed outwardly through a window, and a photodetector for sensing light reflected from a target indicia such as a bar code. The device also comprises a digitizing means for converting the analog signal from the photosensor indicative of the reflectivity of the target indicia into a digital data signal representative thereof. The digital bar pattern is provided to the associated computer along the same transmission means as the positional data.
