Micromechanical Device For Infrared Sensing

View page
US Patent:
7825381, Nov 2, 2010
Filed:
Feb 27, 2008
Appl. No.:
12/072702
Inventors:
Matthew Erdtmann - Londonderry NH, US
Jing Zhao - Winchester MA, US
Guanghai Jin - Boxborough MA, US
Assignee:
Agiltron, Inc. - Woburn MA
International Classification:
G01J 5/38
US Classification:
25033902
Abstract:
A micromechanical device including an improved sensing element and improved bending elements is described. Sensing elements include multi-layered structures which are thinner, lighter, and flatter than structures presently known within the related arts. Bending elements include structures which separately respond to illumination by an infrared source so as to twist a sensing element. Micromechanical pixels may be arranged to form two-dimensional arrays of infrared sensitive pixels. Arrays of micromechanical pixels are applicable to imaging devices for use within the fields of security and surveillance, firefighting, automotive safety, and industrial monitoring.

Noise Reduction Method For Imaging Devices

US Patent:
20070296838, Dec 27, 2007
Filed:
Jun 26, 2006
Appl. No.:
11/474893
Inventors:
Matthew Erdtmann - Londonderry NH, US
International Classification:
H04N 9/64
US Classification:
348243
Abstract:
A method for reducing the noise equivalent temperature difference associated with imaging devices having a detection array including micro-cantilevers and a charged-coupled device or a complementary metal oxide semiconductor imager is presented. The method includes calculating horizontal and vertical pixel ratios based upon the number of receptor pixels and micro-cantilever pixels, defining composite pseudo-pixels comprised of at least two receptor pixels, capturing at least one frame of an image, calculating the composite intensity for each composite pseudo-pixel based on the intensities of the receptor pixels therein, and reconstructing each frame so that receptor pixels within each composite pseudo-pixel are displayed with the appropriate composite intensity. While the present method lowers pixel resolution, the composite pseudo-pixels maintain image resolution within the reconstructed image.

Smoke Detector With External Sampling Volume

US Patent:
20130286391, Oct 31, 2013
Filed:
Mar 13, 2013
Appl. No.:
13/799816
Inventors:
Matthew Erdtmann - Londonderry NH, US
International Classification:
G01N 21/53
US Classification:
356341, 2503385
Abstract:
In accordance with certain embodiments, a smoke detector comprises a housing, a light source, one or more light detectors, and an evaluation circuit for determining the presence of smoke particles outside the housing based on light emitted from and reflected back into the housing, as well as light emitted within the housing without emission therefrom.

Smoke Detector With Ambient-Light Sensor

View page
US Patent:
20130286392, Oct 31, 2013
Filed:
Mar 13, 2013
Appl. No.:
13/799826
Inventors:
Matthew Erdtmann - Londonderry NH, US
International Classification:
G01N 21/53
US Classification:
356341, 2503385
Abstract:
In accordance with certain embodiments, a smoke detector utilizes a reflected-light signal and sensed ambient light to determine the presence of smoke particles.

View page
US Patent:
20130286393, Oct 31, 2013
Filed:
Mar 13, 2013
Appl. No.:
13/800071
Inventors:
Matthew Erdtmann - Londonderry NH, US
International Classification:

Abstract:
In accordance with certain embodiments, a smoke detector utilizes broadband light with a plurality of wavelengths to determine the presence of smoke.

Smoke Detection Using Two Different Wavelengths Of Light And Additional Detection For Measurement Correction

View page
US Patent:
20180372622, Dec 27, 2018
Filed:
Jul 6, 2018
Appl. No.:
16/029002
Inventors:
Matthew ERDTMANN - Londonderry NH, US
International Classification:
G01N 21/27
G08B 17/107
G01N 21/53
G08B 17/113
G08B 29/18
Abstract:
In accordance with certain embodiments, a smoke detector determines the presence of smoke particles outside its housing based on measurements of light detected at different wavelengths and corrected based on an ambient light level.

System And Method Of Smoke Detection Using Multiple Wavelengths Of Light

View page
US Patent:
20180149590, May 31, 2018
Filed:
Jan 26, 2018
Appl. No.:
15/881079
Inventors:
Matthew ERDTMANN - Londonderry NH, US
International Classification:
G01N 21/53
Abstract:
In accordance with certain embodiments, detection of a fire event via detection of scattered light of at least two wavelengths is based on rates of change between measurements of the scattered light of the different wavelengths.

System And Method Of Smoke Detection Using Multiple Wavelengths Of Light And Multiple Sensors

View page
US Patent:
20180059008, Mar 1, 2018
Filed:
Oct 23, 2017
Appl. No.:
15/790280
Inventors:
Matthew ERDTMANN - Londonderry NH, US
International Classification:
G01N 21/27
G08B 17/107
G01N 21/53
Abstract:
In accordance with certain embodiments, detection of a fire event via detection of scattered light of at least two wavelengths is initiated only after a signal from a light detector and/or a sensor for detecting one or more fire signatures other than smoke exceeds a triggering threshold.
