Airport Inset Lights With A Flow Path For Pressure Equalization
US Patent:
2010000, Jan 14, 2010
Filed:
Jul 8, 2008
Appl. No.:
12/169054
Inventors:
Russell Lewis Tartock - Springfield IL, US
Anthony W. Wilson - Springfield IL, US

International Classification:
E01F 9/00, F21S 8/00
US Classification:
3621531
Abstract:
An airport inset light for an airport runway light system comprises a light fixture incorporating a light source that is covered with a lens. A flow path can be provided in the light fixture such that air can pass unrestrictedly between an exterior environment and an interior space of the light fixture. The flow path can be covered or filled with a hydrophobic filter material, which allows for the light fixture interior to exchange air with its exterior environment. Such a flow path can create pressure equalization between the exterior environment and the light fixture interior to prevent the formation of a vacuum in the light fixture interior. Hence, it can eliminate the possibility of water entering the interior of the light source due to pressure differential between the environment and the light source interior.
Smart Monitoring And Wireless Query System And Method
US Patent:
2010001, Jan 21, 2010
Filed:
Jul 16, 2008
Appl. No.:
12/174378
Inventors:
Russell Lewis Tartock - Springfield IL, US

Todd Hanson - Loretto MN, US
Al Cable - Springfield IL, US

International Classification:
H04Q 5/22
US Classification:
340 101
Abstract:
A smart monitoring and wireless query system is disclosed which includes a sensor suite, an RFID chip, and a microcontroller. The sensor suite with appropriate sensors can be mounted to a separate circuit board installed in a housing of a fixture with the RFID chip in proximity to the sensors. The sensor suite includes, but is not limited to, various sensors for monitoring humidity, light intensity, temperature, and/or power consumption to determine the entire status of a product. A microcontroller can be employed to determine the condition of the fixture from the sensor inputs and convert that information into an RFID signal having a specific timing and pattern. A remote reader can receive said RFID signal pattern from the fixture and can then decode the signal in order to identify which particular fixture from which the signal is received and the status of that particular fixture.
Acoustic Wave Particulate Sensor
US Patent:
2007013, Jun 21, 2007
Filed:
Dec 16, 2005
Appl. No.:
11/305923

Michael Rhodes - Richfield MN, US
International Classification:
G01N 29/00, G01N 37/00
US Classification:
073061750
Abstract:
An acoustic wave particulate sensor system is disclosed, which includes a piezoelectric substrate; and one or more acoustic wave sensing elements formed upon said piezoelectric substrate. A housing can be provided for maintaining said piezoelectric substrate and the acoustic wave sensing elements, wherein the acoustic wave sensing elements, when exposed to a substance containing particulates, such as, for example, engine oil, responds to a phase change, frequency change, and/or noise level change associated with said particulates in order to identify a noise signature of said particulates and therefore identify differences among said particulates to detect data associated with said particulates.
