Colorimeter For Dental Applications
View pageUS Patent:
6525819, Feb 25, 2003
Filed:
Aug 2, 1999
Appl. No.:
09/365438
Inventors:
S. Brett Delawter - La Cañada CA
Gregg A. Wagner - Boulder CO

Assignee:
PocketSpec Technologies Inc. - Denver CO
International Classification:
G01J 350
US Classification:
356406, 356425, 433 29
Abstract:
The invention is a colorimeter for dental applications comprising a hand-held probe, similar in size to a dental drill, attached by an electrical cable to a small self-contained display module. The calorimeter provides the capability for measuring the colors of a number points along a line on the surface of an object such as a tooth. A measurement is made while placing the tip of the probe against, or in close proximity to, the surface of the object. The display module to which probe attaches contains a microprocessor and provides a control, display and data interface to the operator. The display module can be adapted for fastening to the wrist of the operator thereby leaving both hands free to manipulate the probe and other tools. The calorimeter is particularly well suited for measuring the color of teeth in a dentists office in preparation for making dental prostheses which accurately match the color of natural teeth. The colorimeter generates from a single measurement an array of color data points measured along a line on the surface of an object.
Handheld, Portable Color Measuring Device With Display
View pageUS Patent:
6798517, Sep 28, 2004
Filed:
May 11, 2001
Appl. No.:
09/854344
Inventors:
Gregg Wagner - Boulder CO
Gary Emerson - Golden CO
Gary Emerson - Golden CO
Assignee:
Color-Spec Technologies, Inc. - Denver CO
International Classification:
G01J 350
US Classification:
356406, 356407
Abstract:
A handheld, portable color measuring device for measuring the primary colors of red, green and blue in a color target to be analyzed and connected to a built-in LCD display or connected to a separate personal computer. The color measuring device includes an elongated color measuring probe housing. A hollow cone shaped probe tip is attached to one end of the probe housing. A target contact end of the probe tip is placed against a color target to be measured. Inside the probe housing is a battery powered white LED light source connected to a color measurement switch. When the measurement switch is actuated, the white light source illuminates the color target surrounded by the target contact end of the probe tip. A light pipe is centered inside the probe housing and inside a portion of the probe tip. The light pipe captures the reflected light off the color target and projects the captured light onto a 3 color (RGB) sensor.
Particle Counter With Strip Laser Diode
View pageUS Patent:
6859277, Feb 22, 2005
Filed:
Aug 27, 2002
Appl. No.:
10/228577
Inventors:
Gregg A. Wagner - Boulder CO, US
Thomas Bates - Westminster CO, US
Thomas Bates - Westminster CO, US
Assignee:
Particle Measuring Systems, Inc. - Boulder CO
International Classification:
G01N021/00
US Classification:
356337, 356338
Abstract:
A fluid particle counter comprising an inlet jet tip producing an air flow, a strip laser diode producing a laser beam, and a beam shaping system that includes an aspheric collimating lens, an achromatic spherical lens, a cylinder lens, and a series of cascading apertures. A retarder rotates the polarization so that the TE mode is along the direction of fluid flow. The optical system is designed so that along the flow axis the laser beam is single mode, while the multimodes due to the strip laser are constrained to the dimension perpendicular to the flow. The beam is pinched to a 35 micron waist and has a Gaussian profile along the flow direction which permits locating the beam within 3. 5 mm of the flow tip while preventing stray light scattering from the tip. The beam profile along the axis perpendicular to the flow is closer to a square wave than a Gaussian. The particle counter output is substantially free of all noise except noise created by light scattered from molecules of the fluid, even for volumetric particle counters.
Housing For Portable Handheld Electronic Device

6913201, Jul 5, 2005
Filed:
Jul 10, 1998
Appl. No.:
09/113446
Inventors:
Gregg Wagner - Boulder CO, US

Robert Stewart - Boulder CO, US
Assignee:
Allflex USA, Inc. - Dallas TX
International Classification:
G06K007/10
A47B081/00
A47B081/00
US Classification:
235472, 3122232
Abstract:
An injection-molded housing for a handheld portable electronic device employs a minimal number of parts. The housing, made of a thermoplastic elastomer, is watertight, buoyant and exceptionally rugged. Principal components of the housing snap together without the need for adhesive bonding or fasteners using a tongue-and-groove closure mechanism.
Particle Counter With Laser Diode
View pageUS Patent:
7576857, Aug 18, 2009
Filed:
Aug 20, 2004
Appl. No.:
10/923339
Inventors:
Gregg A. Wagner - Boulder CO, US
Assignee:
Particle Measuring Systems, Inc. - Boulder CO
International Classification:
G01N 21/00
US Classification:
356337, 356338
Abstract:
A liquid particle counter for optically detecting an unconstrained particle suspended in a flowing liquid includes a sample chamber having a liquid inlet and a liquid outlet; a laser diode module producing a symmetrically collimated laser beam; a beam shaping optical system directing the laser beam at the sample chamber; and an optical detector located to detect light scattered by the particle in the sample chamber, the detector producing an electric signal characteristic of a parameter of the particle. The laser beam has an energy of a watt or more and passed through an aperture in a black glass aperture element in the sample chamber. The black glass aperture element removes diffracted and stray light from the beam without damage to the sample chamber.

Self Aligning, Low Power Character Reading Apparatus
View pageUS Patent:
55175775, May 14, 1996
Filed:
Feb 25, 1994
Appl. No.:
8/201763
Inventors:
Gregg A. Wagner - Boulder CO
Assignee:
Soricon Corporation - Boulder CO
International Classification:
G06K 900
US Classification:
382135
Abstract:
An apparatus for reading information off a document such as a check is herein disclosed. The apparatus includes an apparatus housing defining a specific path through which the document is intended to pass during normal operation of the apparatus. The apparatus also includes an arrangement including a read head positioned at a fixed point on the path and cooperating circuitry for reading specific information off of the document as the document is caused to move through the path and across the read head. And, the apparatus includes an arrangement for moving the document through the path and across the read head along with causing the document to engage against the read head as the document moves across the read head. This document moving arrangement includes an arrangement supporting a freely rotating idler roller which is positioned to engage the document against the read head. Also, this document moving arrangement is configured in a way which places a moment on the document as it moves through the path so as to insure that the document crosses the read head in a predetermined orientation with reset to the read head.
