摘要： Positive and negative ion output are balanced in an electrical ionizer having positive and negative ion emitters, and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters. At least one of the positive and negative high voltage power supplies switches between a high state and a low state. An ion balance sensor is located close to the ion emitters and outputs a voltage value. An ion balance sensor set point voltage value is stored. The voltage value is set to provide a balanced ion condition in the work space near the electrical ionizer. During operation of the electrical ionizer, the output voltage value of the ion balance sensor is compared with the set point voltage value. One of the switchable high voltage power supplies is switched to a high state when it is detected as a result of the comparison that the output voltage value of the ion balance sensor exceeds the set point voltage value in a first direction by a first predetermined amount, and the one of the switchable high voltage power supplies is switched to a low state when it is detected as a result of the comparison that the output voltage value of the ion balance sensor exceeds the set point voltage value in a second direction by a second predetermined amount, the second direction being opposite of the first direction.

摘要： A self-balancing ionizing circuit for electrical static eliminators having high voltage (pointed) discharge electrodes employs an insulative duct spaced peripherally thereabout. The duct has at least an open exit end with a non-conductive protective grille at the duct terminus in longitudinally spaced disposition from said electrodes. One side of an ungrounded secondary coil of an A.C. high voltage transformer is directly or resistively connected electrically to the discharge electrodes while the other side of the transformer secondary is electrically coupled to an ungrounded conductive band supported within the insulative duct adjacently spaced from the discharge electrodes to define a floating reference electrode with respect thereto. The electric field for ionization is produced between the discharge electrodes and the reference electrode. Grounding is effected only by way of an external conductive chassis for the system which is shielded from the internal ionization process by the dielectric of the insulative duct. Isolating the reference electrode from ground permits substantial voltages to be developed thereon without creating the ionization imbalance normally produced by adjacent grounded components, such as grounded casings or the like. Balancing of positive and negative ion production is independent of capacitors or other electrical components, and no mechanical adjustment is required to compensate for changes in environmental factors or contamination conditions. With no capacitors which can become leaky, the system provides high reliability with fewer parts, thereby minimizing costs.

摘要： A laser scanner for reading symbology, such as barcodes. The laser scanner includes a housing, a laser source or generator disposed in the housing and operative to generate a laser beam, and an output window supported by housing and being positioned to receive the laser beam incident thereon. The window is operative to transmit the laser beam therethrough at a symbology target. In one embodiment, the window includes a vertical wedge angle between front and rear surfaces of the window that is oriented substantially in alignment with a vertical axis defined by the window. The vertical wedge angle is preferably oriented perpendicular to a horizontally-extending scanning line of the laser beam on the window. In one embodiment, the vertical wedge angle is substantially the same along the entire length or width of the window.

摘要： An autofocus system and method for performing the same for a liquid lens. The autofocus system in one embodiment includes a liquid lens having a variable focal length that is adjusted by varying an input voltage to the lens, distance detection circuitry operative to measure a distance to a target to be scanned, and control circuitry associated with the liquid lens for focusing the lens. The control circuitry receives a signal from the distance detection circuitry representing a measured distance to the target. Control logic, preferably implemented by the control circuitry in one embodiment, calculates a voltage value corresponding to the measured distance to the target and generates an output voltage approximating the calculated voltage value to adjust the focus the lens.

摘要： Illumination apparatus includes a light source which directs a polarized source beam in a downstream direction along an optical axis and desirably focuses the beam. A polarization-altering element downstream from the source such as a birefringent plate alters the polarization in a portion or portions of the source beam, so that the altered beam includes portions having different polarization directions. The altered beam passes downstream through a polarization-selective filter. The output beam from the polarization-selective filter can include either portion depending on the orientation of the filter. The arrangement can be used to provide a spot of a given size and shape at the focal location in a scanner such as a bar code scanner. The size and depth of field of the spot can be varied dynamically during operation.

摘要： A laser scanning system and method for scanning symbology targets such as barcodes. The scanning system in one embodiment includes at least one laser source and a pair of wobbling mirrors generally disposed towards opposite ends of a centrally-positioned rotatable mirrored spinner. In one embodiment, the central spinner is double-sided having reflecting surfaces on opposites sides thereof. Laser beams projected onto each wobbling mirrors are in turn redirected onto each reflecting surface of the double-sided rotating spinner which produces a pair of rotating scanning beams for reading a symbology target.
