APPARATUS AND APPROACH FOR ACCURATE MONITORING OF SPACE
First Claim
1. An intrusion detection system comprising:
- a controller;
a transmitter module connected to the controller; and
a receiver module connected to the controller; and
wherein;
the controller comprises an output for connection to an intrusion alarm; and
if an object detected by the receiver module is determined by the controller to have a speed within a predetermined range and a distance from a detection point within a predetermined range, then the object is classified as an intruder.

Abstract
An intrusion device having an electromagnetic wave transmitter and receiver with a transmitting and receiving antenna, respectively. The transmitter and receiver may be connected to a microcontroller. The device may operate in a microwave and passive infrared range, and detect speed and position of an intruder, such as an object or a person. The device may be customized to indicate intruders within a certain range of speed and range of distances. Further, the device may have a field of view that may be varied. The device may indicate a direction of movement of the intruder. The transmitter, receiver, controller and antenna may be contained on a compact printed circuit board. Much of the electronics may be incorporated on a monolithic integrated circuit. The customization or adjustment of ranges of speed, slow and fast limits, and distance, near and far limits, may be a reason to regard the device as smart.

10. An intruder detection mechanism comprising:
-
a transmitter; a receiver; and a controller; and wherein; the transmitter emits an electromagnetic transmission signal; the receiver detects a reflected signal of the electromagnetic transmission signal; the controller processes an attenuated electromagnetic transmission signal and the reflected signal into speed and distance information about an object that caused the reflected signal; and the speed and distance information indicate whether the object is an intruder. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for detection of intrusion, comprising:
-
self-testing a passive infrared (IR) module; self-testing a microwave module; activating a fault alarm if the passive infrared module or the microwave module fails the self-testing; and checking whether the passive infrared module triggers the fault alarm; and wherein; if the passive IR module does not trigger the fault alarm, then check again whether the passive infrared module triggers the fault alarm, until the passive infrared module triggers the fault alarm or the method is terminated; if the passive infrared module triggers the fault alarm, then store microwave series data from the microwave module; a velocity of an intruder is calculated; whether the intruder has a velocity in a predetermined range is checked; if the intruder has not a velocity in the predetermined range, then check again whether the passive infrared module triggers the fault alarm, or if the intruder has a velocity in the predetermined range, then calculate a distance between the intruder and a detection device; whether the intruder is within a predetermined distance of the detection device is checked; if the intruder is not within a predetermined distance of the detection device, then check again whether the passive infrared module triggers the fault alarm; and if the intruder is within a predetermined distance of the detection device, then an intrusion alarm is triggered. - View Dependent Claims (20)
