Patent number: 5834750Abstract: A system for bar code reading and scanning is provided having automatic bar code signal size control. In the first embodiment of the system, a processor selects on successive scans of a bar code one of a plurality of different optical power levels from a laser diode which provides a light beam illuminating the bar code. This selection is responsive to the size of the signal from a photo-detector which receives returned light from the bar code during scanning. The signal size is detected by a signal size detecting circuit, and is measured by the processor during scanning. In a second embodiment of the system, the processor calculates an optical power level after every two consecutive scans across the bar code. The laser power level is calculated differently for alternative scans occurring in different orders (even or odd counting from the first scan).Type: GrantFiled: September 6, 1995Date of Patent: November 10, 1998Assignee: PSC, Inc.Inventors: Edward P.

Patent number: 5804809Abstract: A unitary hand-held bar code scanner and reader produces an elliptical beam, oriented with its major axis along the direction of the bars, utilizing optics employing far field diffraction effects to shape the beam and maintain its elliptical aspect (length to width ratio) constant over a distance in front of the scanner were bar codes may be located. The optics eliminates parallax even though the photodetector and light source (preferably a laser diode) are located offset from each other on a board on which the optics are mounted. A housing assembly has channels which mount the board therein without shock absorbing devices. A digital microcomputer controller and peripheral devices regulate the optical power output from the laser diode and prevents catastrophic failure, if the electrical current through the laser diode exceeds safe limits.Type: GrantFiled: August 7, 1995Date of Patent: September 8, 1998Assignee: PSC Inc.Inventors: Jay M.

Patent number: 5773816Abstract: An improved photodetector integrator circuit is provided having a photodetector, such as a photodiode, which produces photocurrent responsive to incident illumination. The photodetector is coupled to an integrator stage which converts the photocurrent into voltage and integrates the voltage over an integration period to provide an output signal. A window comparator in the circuit receives the output signal from the integrator stage and compares the output signal to a first threshold and a second threshold to provide, as a measurement signal, a pulse having a width which corresponds to the time interval over which the output signal increases from the first threshold to the second threshold. In the window comparator, the second threshold is greater than the first threshold.Type: GrantFiled: October 7, 1996Date of Patent: June 30, 1998Assignee: Lucid Technologies Inc.Inventor: Scott R.
