Patent number: 6330521Abstract: A method and apparatus for aligning a target within a field of view of an optical scanner is provided. In an optical scanner having a field of view, apparatus for indicating whether a target is aligned within said field of view includes a microprocessor and an alignment indicator. The alignment indicator is electrically connected to the microprocessor and includes, for example, a light emitting diode. The microprocessor defines a first zone and a second zone within the field of view and determines whether the target is within the field of view. If the target is within the field of view, the microprocessor identifies a target alignment point on the target. The microprocessor determines whether the target alignment point is within either the first zone or the second zone and sends a signal to the alignment indicator. In response, the alignment indicator provides an indication indicating whether the target alignment point is located within the first zone, the second zone, or neither.Type: GrantFiled: December 29, 2000Date of Patent: December 11, 2001Assignee: Robotic Vision Systems, Inc.Inventors: James C.

Patent number: 5637852Abstract: A bar code scanner for stationary disposition at a counter to projecting a scanning pattern comprising first, second, third, fourth and fifth groups of parallel scan line within a relatively narrow, yet diverging, volume, e.g., pyramid, cone, etc., centered about a projection axis. The scanner includes a compact housing mounted on an adjustible base. The housing includes a window, five stationary mirrors, a laser diode, a rotating reflective polygon for sweeping the laser beam from the diode across the mirrors and out a window so that the projection axis is substantially but not precisely perpendicular to the window. The scanner also includes a fixed curved collecting mirror and a concentrating lens to focus light which is reflected off of a bar code to a photodetector. One mirror extends along an axis parallel to the transverse axis to produce the first group of scan lines.Type: GrantFiled: June 7, 1995Date of Patent: June 10, 1997Assignee: Metrologic Instruments, Inc.Inventors: Carl H.
