Method And System For Shaping A Spatial Response Of A Spatial Filter

View page
US Patent:
7304285, Dec 4, 2007
Filed:
Nov 19, 2004
Appl. No.:
10/993938
Inventors:
Stephan Hengstler - Campbell CA, US
Ramakrishna Kakarala - Santa Clara CA, US
Assignee:
Avago Technologies ECBU IP (Singapore) Pte. Ltd. - Singapore
International Classification:
G01J 1/44
G01J 3/50
G06K 9/00
G06K 9/62
G01N 21/00
US Classification:
250206, 250226, 382181, 382209, 356435
Abstract:
A spatial filter includes a number of photodetectors that generate individual signals in the time domain. The individual signals are subsequently divided and grouped to create the I and Q channels output from the spatial filter. Prior to the formation of the I and Q channels, a window function is used to shape the spatial response of the spatial filter.

Apparatus For Controlling The Position Of A Screen Pointer Based On Projection Data

View page
US Patent:
7379049, May 27, 2008
Filed:
Dec 13, 2004
Appl. No.:
11/010666
Inventors:
Stephan Hengstler - Campbell CA, US
Todd S. Sachs - Palo Alto CA, US
Assignee:
Avago Technologies ECBU IP Pte Ltd - Singapore
International Classification:
G09G 3/38
US Classification:
345158, 345157, 345166, 345163
Abstract:
A device such as an optical mouse includes a light source for illuminating an imaging surface, thereby generating reflected images. The device also includes an optical motion sensor for generating one-dimensional projection data based on the reflected images, filtering the projection data, and generating movement data based on the filtered projection data. The movement data is indicative of relative motion between the imaging surface and the device.

Stable Optical Switch With Reduced Power Consumption

View page
US Patent:
20040067009, Apr 8, 2004
Filed:
Oct 7, 2002
Appl. No.:
10/266877
Inventors:
Kenneth Scholz - Palo Alto CA, US
John Uebbing - Palo Alto CA, US
Julie Fouquet - Portola Valley CA, US
Stephan Hengstler - Campbell CA, US
Tyler Sims - Keizer OR, US
International Classification:
G02B006/35
US Classification:
385/016000
Abstract:
The optical switch operates in two stages. In the first stage, the bubble is “blown” into the trench. In the second stage, the sidewalls are heated to achieve a dry wall condition by improving the thermal transfer path from the heat source to the reflecting wall. Separate side heaters are placed in thermal contact to the sidewalls. This results in a switch that is more stable, energy efficient, and has a longer mean time to failure.

Video-Frame Data Receiver With Low Frame Capture Rate

View page
US Patent:
20100177176, Jul 15, 2010
Filed:
Jan 15, 2009
Appl. No.:
12/354134
Inventors:
Stephan Hengstler - Campbell CA, US
Assignee:
ALVERIX, INC. - San Jose CA
International Classification:
H04N 7/18
H04N 9/475
US Classification:
348 61, 348512, 348E09034, 348E07085
Abstract:
The present disclosure relates generally to a video frame data receiver that is capable of image acquisition at low frame rates. Such video frame data receivers may be used to capture images from diagnostic tests or assays in which lower frame capture rates are sufficient including, for example, lateral flow test strips.

In-Vitro Diagnostic Device Using External Information In Conjunction With Test Results

View page
US Patent:
20130066562, Mar 14, 2013
Filed:
Sep 9, 2011
Appl. No.:
13/229292
Inventors:
Stephan Hengstler - Campbell CA, US
Tong Xie - San Jose CA, US
Assignee:
ALVERIX, INC. - San Jose CA
International Classification:
G06F 19/10
G06F 17/18
US Classification:
702 19
Abstract:
A system and method for augmenting or adding to the information used by an in-vitro diagnostic or other diagnostic device to generate results of a test is disclosed. A diagnostic device is capable of generating test results based on a sample, such as a sample provided by a patient, and is also capable of receiving additional information to enhance the results providable by the device. For example, an in-vitro diagnostic device is configured to read a lateral flow assay test, and is configured to receive additional diagnostic, network, test identification, or environmental information over a network. Using both the result of the diagnostic test and the additional information, the disclosed device provides more thorough, accurate, and reliable diagnostic information. The results generated by the device may be communicated to an appropriate remote device to enhance the results obtainable by such tests.

Distributed Network Of In-Vitro Diagnostic Devices

View page
US Patent:
20130066563, Mar 14, 2013
Filed:
Sep 9, 2011
Appl. No.:
13/229301
Inventors:
Stephan Hengstler - Campbell CA, US
Tong Xie - San Jose CA, US
Assignee:
ALVERIX, INC. - San Jose CA
International Classification:
G06F 19/10
G06F 19/26
US Classification:
702 19
Abstract:
A system is disclosed in which a plurality of in-vitro diagnostic (IVD) devices each include a network communication device for connecting to a publicly accessible data network. For example, IVD devices are provided with a cellular modern for connecting to a public cellular network. These IVD devices connect to the data network upon completion of a diagnostic test, and upload results of the test, as well as other appropriate data, to a remote device which is also on the network. The IVD devices also download appropriate data from remote network elements. The remote network element may be a network element such as a Hospital Information System (HIS) or Laboratory Information System (LIS) database. Alternatively, the remote device may be a remote server or another IVD device. This connectivity enables the system to accumulate diagnostic test data, and to analyze, report, and/or update the IVD devices based on the accumulated data.

Modular Assay Reader Device

View page
US Patent:
20220357321, Nov 10, 2022
Filed:
Jul 22, 2022
Appl. No.:
17/814308
Inventors:
- Franklin Lakes NJ, US
Stephan Hengstler - Campbell CA, US
Vincent C. Moyer - Los Gatos CA, US
Benny Wing Hung Lai - Fremont CA, US
International Classification:
G01N 33/558
G16H 10/40
C12M 1/34
G01N 21/01
G01N 35/00
G01R 1/20
G01N 33/543
G06K 7/10
Abstract:
Certain aspects relate to systems and usage techniques for modular lateral flow assay reader devices that can receive a number of different modules having a barcode scanning input device and optional network connectivity capabilities. A barcode scanning module can provide a simple input method that reduces errors compared to manual data entry. A network connectivity module can enable transmission of test results over a public network for standardizing, tracking and electronically connecting test results from assay reader devices located throughout a network. Such devices can programmatically implement a simplified workflow whereby pressing a single button readies the device for imaging, analyzing, and data storage/transmission and, in some implementations, configures the device to operate in one of a plurality of device operation modes.
