US Patent:

62981714, Oct 2, 2001
Filed:

May 15, 2000
Appl. No.:

9/571062
Inventors:

Christopher W. Lorton - Bothell WA
James C. Griner - Woodinville WA
Creed F. Jones - Lake Stevens WA
Richard P. Williams - Monroe WA
Larry Rystrom - Mill Creek WA
James D. Orrell - Bothell WA
International Classification:

G06F 15316
G06K 964
US Classification:

382278
Abstract:

A high speed system for locating and decoding glyphs on documents is disclosed. The system includes acquiring one or more images of a document containing a glyph. One-dimensional projections of the images are correlated against a reference function to locate the glyph in the images. The position of the glyph is refined by correlating against a kernel designed to have a maximum response when aligned over a corner of the glyph. Symbols in the glyph are decoded utilizing a kernel which generates a positive response for one symbol type and a negative response for the other.

Filed:

Oct 30, 2018
Appl. No.:

16/175550
Inventors:

- Carlsbad CA, US
Christopher MARTIN - Bothell WA, US
Frank METTING - Bothell WA, US
Jason MECHAM - Snohomish WA, US
Robert DAIN - Lynnwood WA, US
Larry RYSTROM - Mill Creek WA, US
Paul Adrian BOESCHOTEN - Redmond CA, US
Steven W. LYTLE - Mill Creek WA, US
International Classification:

G02B 21/36
Abstract:

Embodiments relate to systems and methods for sample image capture using integrated control. A digital microscope or other imaging device can be associated with a sample chamber containing cell, tissue, or other sample material. The chamber can be configured to operate using a variety of environmental variables, including gas concentration, temperature, humidity, and others. The imaging device can be configured to operate using a variety of imaging variables, including magnification, focal length, illumination, and others. A central system control module can be used to configure the settings of those hardware elements, as well as others, to set up and carry out an image capture event. The system control module can be operated to control the physical, optical, chemical, and/or other parameters of the overall imaging environment from one central control point. The variables used to produce the image capture can be configured to dynamically variable during the media capture event.

20180157021, Jun 7, 2018
Filed:

Nov 29, 2017
Appl. No.:

15/826021
Inventors:

- Carlsbad CA, US
Paul BOESCHOTEN - Redmond WA, US
Andrew GUNDERSON - Bothell WA, US
Larry RYSTROM - Mill Creek WA, US
Chris GNEHM - Bothell WA, US
International Classification:

G02B 21/00
G02B 21/36
G01N 21/64
G03F 7/20
Abstract:

A method for generating a composite image obtained in a fluorescence imaging system, comprising: determining the physical locations of a pinhole mask relative to a sample required to construct a full composite confocal image; generating in a control module a randomized order for the determined physical locations; moving the photomask or the sample to the determined physical locations in the randomized order under control of the control module and using a translation stage; illuminating the sample through the photomask using an excitation light; capturing a plurality of images at each of the physical locations using a sensor in order to generate a set of data points; using the randomized order to generate a composite image based on the set of data points and measuring the brightness of at least some of the data points; and adjusting the brightness of some of the set of data points.

Filed:

Appl. No.:

15/826125
Inventors:

- Carlsbad CA, US

Larry RYSTROM - Mill Creek WA, US
Chris GNEHM - Bothell WA, US
International Classification:

G02B 21/00
G01N 21/27
Abstract:

A method for calibrating an imaging system, comprising: illuminating a sample through a pinhole mask using an excitation light; capturing an image of the sample using a sensor; converting the image into data; in a processing module: filtering the data using known spacing of pinholes in the pinhole mask to obtain data that corresponds to the spacing, using a threshold to identify regions of the remaining data that are bright enough to be associated with a pinhole, calculating the centroids of the regions, and fitting a known pattern for the pinhole mask to the regions in order to identify the best fit for the data; and storing, in a storage medium, the best fit data for use in a subsequent confocal capture routine.
