US Patent:

7874207, Jan 25, 2011

Filed:

Jan 29, 2009

Appl. No.:

12/362134

Inventors:

Thomas Center Galley - Sedalia CO, US
Arnell Jean Galley - Sedalia CO, US
Harbinder S. Pordal - Mason OH, US
James F. Yoder - Blanchester OH, US

Assignee:

Intrinsic Minds, LLC - Sedalia CO

International Classification:

G01W 1/00

US Classification:

7317006

Abstract:

In order to provide a robust, weather resistant, portable, low-noise, relatively inexpensive, wind direction detection device, disclosed herein is a method and device for detecting fluid flow direction based on sensing a temperature variation transmitted from a temperature variation source to one or more temperature sensors. One or more indicators are utilized to communicate the measured fluid flow direction to a user. An implementation of the fluid flow direction detection device utilizes a resistance heater as the temperature variation source, thermistors as the temperature sensors, and light emitting diodes (LEDs) corresponding to each thermistor as the indicators. The thermistors and LEDs are arranged in a circular fashion around the resistance heater to accurately detect the direction of a thermal plume generated by the resistance heater.
