摘要： A multi-plane scanner having a dual plane scanner with a horizontal window and a vertical window and a load cell/weigh platter weighing apparatus such that the weigh platter itself is a dual plane object with vertical and horizontal sections. The size and orientation of the planes of the weigh platter correspond to the size and orientation of the scan windows of the dual plane scanner, and each plane of the weigh platter has a transparent area (typically central), or “platter window”, corresponding to a respective scan windows of the scanner for allowing transmission of scanned optical beams and optical barcode signals through each of the planes of the weigh platter. The platter is sufficiently rigid to permit accurate weighing whether the object being weighed is placed solely on the horizontal section of the platter or in part on the vertical section. The vertical and horizontal sections of the platter are sealed together to prevent passage of debris therebetween.

摘要： A method and apparatus for holding an otherwise variable parameter in a scanner approximately constant over a desired scan volume to improve the ability to compensate for unwanted variations in the amplitude modulation depth of a signal is provided, the signal being determined from collected light reflected from a target. In one embodiment, the time domain impulse response of the opto-mechanical system is the parameter which is held approximately constant by appropriately positioning the beam waist so that the beam spot size diverges approximately linearly along the beam axis within the scan volume.

摘要： In an optical data reader, light is aimed out through a window at objects located in front of the window, and reflections from the objects and/or the window itself are detected. The amount of detected light is compared to one or more expected levels to determine when an object is present in front of the window and/or whether the window is properly installed. The optical reader is controlled based on this determination. Control functions that may be implemented in this manner include, for example, waking up the data reader when an object is detected in front of the glass, and disabling the data reader if the window is removed.

摘要： An object recognition system comprises a sensing apparatus for collecting light reflected from objects presented at a point-of-sale machine. The sensing apparatus includes a mechanism, such as a holographic disk or diffraction grating, for separating the color components of the light reflected from the object and directing, the color components onto an optical detector such as a two-dimensional imaging array, or a one-dimensional imaging array or single photo-sensitive optical cell used in conjunction with a rotating mirror. A pattern recognizer compares the spectral response, including the locations, amplitudes and widths of energy peaks of the different color components, against premeasured characteristics of known objects in order to classify the object. The weight of the object can be measured with a scale, and the density of the object calculated, with the weight and density being used by the pattern recognizer to further classify the object. In one embodiment, a plurality of narrowband illumination sources are operated in time-sequential manner, each illuminating with a different wavelength band of light, in order to allow separate color measurements. The object recognition system may be integrated in a single unit along with an optical code reader, and may share all or part of the same exit aperture therewith. The object recognition system may include thermal detection or a particle source and secondary emission detection device, either alone or in conjunction with other object recognition means.

摘要： A power supply circuit for a gas laser has primary circuitry and secondary circuitry supplied by the primary circuitry. A transformer is positioned between the primary circuitry and a secondary circuitry. Within the secondary circuitry is a spark gap and associated circuitry for creating a voltage buildup to achieve a high ionization voltage required for the laser and for releasing the high ionization voltage in pulses for starting the laser. The circuit further includes laser operating supply circuitry associated with the secondary circuitry and the primary circuitry for supplying the laser at a normal operating voltage much lower than the ionization voltage after the laser has started.
