International Classification:
G06K 710
US Classification:
235467
Abstract:
A bar code scanning system such as for use in retail checkout having a scanner housing; a plurality of surfaces facing a scan volume from different directions; and sets of pattern mirrors positioned adjacent the respective surfaces, the housing being positioned above the scan volume and containing one or more laser beam modules and/or a scanning mechanism for producing scanning beams which are routed to the pattern mirrors and out through the respective surfaces into the scan volume.

Video Conferencing Network

View page
US Patent:
50142674, May 7, 1991
Filed:
Apr 6, 1989
Appl. No.:
7/335211
Inventors:
E. Neal Tompkins - Atlanta GA
Thomas C. Arends - Eugene OR
Michael W. Barry - Duluth GA
Assignee:
Datapoint Corporation - San Antonio TX
International Classification:
H04Q 1104
US Classification:
370 62
Abstract:
A video conferencing network for providing videos, audio, and data communication between remote video terminals. Each of the video terminals transmits and receives video, audio, and data information through the network. The network includes a central switching network for receiving audio and video information on one of a plurality of audio/video ports and selectively interconnecting this information to remaining audio/video ports. A centralized controller is in data communication with each of the video terminals and the switching network and controls the configuration of the switching network to provide the appropriate audio and video paths in response to the data received by the controller from the video terminals.

Multiple Focus Optical System For Data Reading Applications

View page
US Patent:
54381878, Aug 1, 1995
Filed:
Jun 18, 1993
Appl. No.:
8/080036
Inventors:
Brad R. Reddersen - Eugene OR
Thomas C. Arends - Eugene OR
Assignee:
Spectra-Physics Scanning Systems, Inc. - Eugene OR
International Classification:
G06K 710
US Classification:
235462
Abstract:
An optical system and method for data reading having a light source which generates an optical beam directed toward an object to be read and a focusing system in the outgoing light path which establishes multiple beam functions. In a preferred application, a scanning system includes a multifocal lens having a single lens element having an inner lens portion of a first focal length and an outer annular lens portion with a second focal length, the scanning system therefore establishing two separate focal positions from a single light source. Alternately, the system includes a focusing lens system with an corrector element disposed in the outgoing optical path, the corrector element having a plurality of optical zones, each zone having a different optical characteristic for modifying a portion of the outgoing optical beam. A zone may be a refractive region, a reflective region, a diffractive region, an empty region, a window region, or combinations thereof.

Method And Apparatus For Detecting Transitions In A Time Sampled Input Signal

View page
US Patent:
54632110, Oct 31, 1995
Filed:
May 7, 1993
Appl. No.:
8/058659
Inventors:
Thomas C. Arends - Eugene OR
Randy D. Elliott - Eugene OR
Assignee:
Spectra-Physics Scanning Systems, Inc. - Eugene OR
International Classification:
G06K 710
US Classification:
235462
Abstract:
A method and apparatus for determining the transitions between binary levels of an input signal such as a scanned bar code label by detecting zero crossings of an approximated second derivative of the input signal. Samples of the input signal are obtained by using delay lines, sample-and-hold circuits, an analog shift register or similar device. The first derivative of the signal is approximated by the slope of a straight line between two sampled points on the waveform. The second derivative is approximated by the difference between two first derivatives. Zero crossings of the second derivative indicating transitions of the input signal may be determined either by detecting a signal peak on both sides of the zero crossing, or by comparing the second derivative signal to zero when the first derivative exceeds a positive or negative threshold. The time between sample points may be adjusted to match a particular range setting of a scanner having a plurality of range settings.

Variable Focus Optical System For Data Reading

View page
US Patent:
54790115, Dec 26, 1995
Filed:
Dec 7, 1993
Appl. No.:
8/164300
Inventors:
Robert W. Rudeen - Eugene OR
Thomas C. Arends - Eugene OR
Assignee:
Spectra-Physics Scanning Systems, Inc. - Eugene OR
International Classification:
G06K 710
US Classification:
250235
Abstract:
An optical system and method for data reading in which a light source generates an optical beam directed toward an object to be read and a variable aperture mechanism positioned in the outgoing light path establishes at least two separate focal planes. The variable aperture device may comprise a variable aperture system in which the size of the aperture is selectively varied about a range within the diffractive limit of the light beam. A preferred aperture mechanism is a liquid crystal aperture with one or more aperture regions which are selectively or consecutively activated. The optical system therefore establishes two or more separate waist locations from a single light source resulting in greater depth of field or multiple depths of field.

In one embodiment, the system has two optical elements, namely a glass main focusing lens and a plastic corrector plate.

Dithering Assemblies For Barcode Scanners

View page
US Patent:
61523720, Nov 28, 2000
Filed:
Sep 19, 1997
Appl. No.:
8/934487
Inventors:
James E. Colley - Junction City OR
James W. Ring - Blodgett OR
Patrick M. O'Donnell - Springfield OR
Thomas C. Arends - Bellevue WA
Assignee:
PSC Scanning, Inc. - Eugene OR
International Classification:
G06K 710
US Classification:
23547201
Abstract:
A compact scan module including a resonantly driven dithering assembly employing feedback and/or travel stops for scanning an illumination beam of a barcode scanner. In one construction the dithering assembly includes one or more travel stops to limit the motion of the mirror assembly with the two travel stop(s) fabricated from damped resilient material to absorb excess energy imparted on the dithering assembly. A first preferred feedback embodiment employs a Hall effect sensor wherein a feedback magnet is connected to the dithering assembly with a Hall effect sensor positioned to sense the varying magnetic field resulting from the varying position of the feedback magnet. A second feedback embodiment incorporates piezoelectric feedback wherein one or more piezoelectric strain sensors are attached to the bending member to provide the position sensing.
