Filed:
Dec 21, 2000
Appl. No.:
09/745210
Inventors:
Joseph L. Chovan - Syracuse NY
Assignee:
Lockheed Martin Corporation
International Classification:
G01B 1126
US Classification:
356138, 356614
Abstract:
A system and method for monitoring deformations in a cavity comprising a method for sensing deformations within a body comprising inserting into the body an optical, deforrmable probe having a plurality of imaging devices spaced at predetermined positions within the probe, providing a light source for illuminating the probe at a first time instant, processing first composite imaging information in response to activation of the light source; at a second time instant, processing second composite imaging information in response to activation of the light source; and comparing the processed first and second imaging information to obtain positional information indicative of movement of at least a portion of the probe occurring between the first and second time instants.

Method And System For Determining Air Turbulence Using Bi-Static Measurements

View page
US Patent:
6590520, Jul 8, 2003
Filed:
Feb 4, 2002
Appl. No.:
10/067154
Inventors:
Daniel Walter Steele - Clay NY
Joseph L. Chovan - North Syracuse NY
Assignee:
Lockheed Martin Corporation
International Classification:
G01S 1395
US Classification:
342 26
Abstract:
A method and system for determining atmospheric disturbances or turbulence is disclosed. The system includes a plurality of sensor arrays, including at least one sensor element, distributed in a predetermined manner. Each of the sensor elements is in communication with a corresponding receiving system that is operable to receive and process energy received from the aircraft. A determination is then made regarding air turbulence by determining a rate of change of signal phase among selected sets of signals received at the receiving systems. A turbulence map is then determined from the determined rate of change of the phase and the angle of the received signal. When the rate of phase change exceeds known levels an indication of turbulence is made.

Sensor For Optically Sensing Air Borne Acoustic Waves

View page
US Patent:
6714306, Mar 30, 2004
Filed:
May 19, 1986
Appl. No.:
06/864481
Inventors:
Joseph Lawrence Chovan - North Syracuse NY
Martin Francis Lowry - Liverpool NY
Evelyn Hope Monsay - Brewerton NY
William Arthur Penn - Baldwinsville NY
William Pattee Whyland - Marcellus NY
Lawrence Richard Snowman - Liverpool NY
Assignee:
Lockheed Martin Corporation - Bethesda MD
International Classification:
G01B 902
US Classification:
356484, 356517
Abstract:
The present invention relates to an optical sensor of air borne acoustic waves. The sensor comprises means for producing mutually coherent optical sampling and reference beams, which may be combined to form an intermediate frequency carrier, the sampling beam being exposed to the acoustic field, in which acoustic wave induced density variations occur. These density variations produce a variation in the index of refraction and thereupon a phase modulation of the sampling beam. This phase modulation may be recovered by an optical detector and a phase detector as an electrical signal representative of the acoustic signal. The invention has application to security systems.

US Patent:
6780672, Aug 24, 2004
Filed:
Jul 29, 2002
Appl. No.:
10/182422
Inventors:
Daniel W. Steele - Clay NY
Joseph L. Chovan - North Syracuse NY
Assignee:
Lockheed Martin Corporation - Bethesda MD
International Classification:
H01L 2144
US Classification:
438107, 438106, 438109, 257686
Abstract:
Micro electromechanical, MEM, components are created which include at least one integrated circuit die ( ). A cavity in the MEM component modules ( ) further allows for the flush mounted attachment of component modules when the component modules are stacked to create MEM system structures. Commonly positioned via holes within the component modules provide for communication among the dies ( ) on the stacked modules. In one embodiment of the invention, module layers are stacked in an alternating manner that further creates, within in the structure horizontal interlocking slots and vertical chambers. The interlocking slots can be used to join a plurality of structures together and the vertical chambers can be used to draw heat from the structure ( ).

US Patent:
7038780, May 2, 2006
Filed:
Jun 20, 2002
Appl. No.:
10/177790
Inventors:
Joseph Lawrence Chovan - North Syracuse NY, US
Donald William Winfield - Camillus NY, US
Lawrence Richard Snowman - Liverpool NY, US
William Arthur Penn - Baldwinsville NY, US
Walter Beeman - Nikomis FL, US
Assignee:
Lockheed Martin Corporation - Bethesda MD
International Classification:
G01N 21/00
US Classification:
356432, 7386118, 73587, 73606
Abstract:
A method for sensing acoustic energy as the energy passes from a more dense to a less dense medium while compensating for energy level loses that may have occurred along the acoustic path of the acoustic energy. The method may be used to replace a multi-sensor system for detecting acoustic energy. The method includes permitting the acoustic energy to progress from a first transmitting medium to a second transmitting medium, the first transmitting medium being more dense than the second transmitting medium and the first medium being contiguous with the second medium along a predetermined interface; disposing an optical sensor in the second medium so that at least a portion of the acoustic energy imposes a modulation proportional to the frequency components of the acoustic energy on a sampling light emitted by the optical sensor; and detecting at least a portion of the sampling light having modulation in response to the portion of the acoustic energy.
