Adaptive Microwave Security Sensor
View pageUS Patent:
8004451, Aug 23, 2011
Filed:
May 27, 2009
Appl. No.:
12/472488
Inventors:
XiaoDong Wu - Roseville CA, US

Assignee:
Honeywell International Inc. - Morristown NJ
International Classification:
G01S 13/00
US Classification:
342 27, 342 28, 342205
Abstract:
A method and apparatus are provided for operating a microwave detector for detecting intruders within a secured area. The method includes the steps of selecting a noise floor based upon a setting of a range setting potentiometer, detecting a magnitude of a signal reflected from a test subject within the secured area that exceeds the selected noise floor and establishing a threshold value for detecting an intruder based upon the magnitude of the detected signal and sensor mounting height.

HONEYWELL INTERNATIONAL INC. - Morristown NJ
International Classification:
G01J 5/02
US Classification:
250340, 250353
Abstract:
This invention relates generally to the field of motion detection sensors, and in particular to a system and method for adjusting the position of a printed circuit board relative to a focusing element. The invention includes a housing having a front opening and an interior cavity. A focusing element is located within the front opening and the detector is coupled to a printed circuit board located within the interior cavity. A cover is coupled to the printed circuit board and disposed within the interior cavity. A cam is operatively coupled with the cover and the printed circuit board for adjusting the position of the printed circuit board such that the detector's position is adjusted relative to the focusing element.
