Filed:
Jul 1, 2005
Appl. No.:
11/173952
Inventors:
Nels Olson - San Diego CA, US
Bahram Kermani - San Diego CA, US
Hongji Ren - San Diego CA, US
Theo Kotseroglou - San Diego CA, US
Assignee:
Illumina, Inc. - San Diego CA
International Classification:
C12Q 1/68
G06F 19/00
US Classification:
435006000, 702019000, 702020000
Abstract:
The invention provides systems and methods for evaluating synthetic reactions such as polymer synthesis reactions. Evaluation of a synthetic reaction product can be based on a quantitative measure of synthesis such as coupling efficiency or yield, and various parameters determined from a separation record obtained for the synthetic reaction product. The invention further provides methods for evaluating a separation method based on various parameters determined from a separation record. The invention can be used to select an appropriate treatment for a synthetic reaction product such as a separation treatment or treatments related to further processing for the desired product. The methods are particularly useful for automated selection of treatments for synthetic reaction products.

Dynamic Autofocus Method And System For Assay Imager

View page
US Patent:
20100157086, Jun 24, 2010
Filed:
Dec 15, 2009
Appl. No.:
12/638770
Inventors:
DARREN R. SEGALE - SAN DIEGO CA, US
JOHN A. MOON - SAN DIEGO CA, US
HONGJI REN - SAN DIEGO CA, US
Assignee:
ILLUMINA, INC - SAN DIEGO CA
International Classification:
H04N 5/225
G06K 9/40
US Classification:
3482221, 382255, 348E05024
Abstract:
A method and system are provided for controlling focus dynamically of a sample imager. The method comprises scanning a sample with an optical assembly that apportions the sample into regions based on a scan pattern. The optical assembly has a focal setting with respect to the sample. The method further comprises shifting the focal setting of the optical assembly during scanning of the sample, and detecting one or more images representative of one of the regions from the sample. The one or more images have associated degrees of focus corresponding to the focal setting of the optical assembly. The method analyzes the image(s) to obtain a focus score or scores corresponding thereto, where the focus scores represent a degree to which the optical assembly was in focus when detecting the images. The method adjusts the focus setting based on the focus score(s).

US Patent:
20130235388, Sep 12, 2013
Filed:
Mar 29, 2013
Appl. No.:
13/853492
Inventors:
John A. Moon - San Diego CA, US
Hongji Ren - San Diego CA, US
Assignee:
ILLUMINA, INC. - SAN DIEGO CA
International Classification:
G01B 11/24
US Classification:
356609
Abstract:
Method of detecting surface features of a microarray. The method includes providing a microarray to an optical scanner, wherein the microarray includes a surface having features. The method also includes carrying out a scanning process using the optical scanner, wherein the scanning process includes: (i) acquiring images of sequential regions on the surface, wherein a defocus spread is applied to the optical scanner during the acquiring, (ii) determining a focus score for the images, (iii) adjusting the optical scanner to a different defocus spread based on the focus score, and (iv) repeating (i) through (iii) at the different defocus spread, thereby acquiring images of further sequential regions on the surface. The method also includes analyzing the images to distinguish different target molecules at the features of the microarray. The images that are analyzed were acquired at the defocus spread and at the different defocus spread during the scanning process.
