US Patent:

6668970, Dec 30, 2003

Filed:

Jun 6, 2001

Appl. No.:

09/875792

Inventors:

Peng Lee - University MS

Assignee:

Acoustic Horizons, Inc. - Pleasanton CA

International Classification:

E04F 1704

US Classification:

181224, 181225

Abstract:

An acoustic attenuator includes an intake air duct having an intake air duct opening leading to an outside environment and a blower fan opening leading to a blower fan. Air is drawn through the intake air duct opening towards the blower fan and a primary reflecting panel disposed in the intake air duct. The primary reflecting panel is configured to reflect sound propagated from the blower fan away from the intake air duct opening.

Appl. No.:

10/680377

Inventors:

Peng Lee - Oxford MS, US

Assignee:

The University of Mississippi - University MS

International Classification:

G08B 3/10
A01M 1/20

US Classification:

3403842, 3403881, 340566, 43107, 431321

Abstract:

A method and system for detecting the presence of subterranean termites, involving use of a thermal imaging camera to scan the structure before installation of an acoustic sensor in order to quickly locate potential areas of subterranean termite infestation, and an acoustic sensor in the form of an accelerometer or the disclosed innovative acoustic sensors having a bandwidth of at least 100 Hz to 15 kHz to detect noises made by the subterranean termites. Information collected by the acoustic sensor may be transmitted to a portable mini-computer (pocket PC) for confirmation and to a central operations center for inclusion in a comprehensive database of termite data and information. A method and system for detecting the presence of dry-wood termites concealed in a structure, involving use of a heat source to warm up the wooden structure of interest and then using a thermal imaging camera to scan the structure for suspicious dry-wood infestation, followed by the use of an acoustic sensor and pattern recognition software to more precisely and accurately locate potential area of dry-wood termite infestation. Additionally, structural damage can be evaluated by the methods discussed herein, including live trees. Additionally, the method can be used to manipulate termite infestation behavior.

Appl. No.:

11/360274

Inventors:

Peng Lee - Oxford MS, US

Assignee:

Homesafe Inspection, Inc. - Oxford MS

International Classification:

G06F 19/00

US Classification:

702 81, 236 1 C

Abstract:

Data on indoor air quality can be obtained using air monitoring stations. Air stations can provide information on odor and chemicals, microscopic airborne particulates, carbon monoxide, relative humidity, temperature and carbon dioxide. This data on indoor air quality, however, does not in itself provide a sufficiently comprehensive picture of indoor air quality. The data can be correlated with an infrared home inspection to facilitate the identification of factors affecting indoor environmental quality in a specific residence. Additionally, data on air quality can be obtained using mold air samples. Additional data on indoor environmental quality can be obtained using a sound pressure level meter to measure sound levels (indoor/outdoor) and temperature changes over time. A report on indoor environmental quality can be provided to a homeowner.
