Abstract
An intrusion detector has a first sensor for monitoring a first condition and a second sensor for monitoring a second condition in a space to be protected against intrusion; a change in the condition sensed by the first sensor in a target area causes the second sensor to be aligned with the same target area; and if both sensors indicate a change in the respective conditions that they monitor an intrusion is indicated.
Claims30
An intrusion detection system comprising:
- first sensor means for monitoring a first condition and second sensor means for monitoring a second condition in a space to be protected against intruders;
- means, responsive to a change in the condition sensed by said first sensor means in a target area, for aligning said second sensor means with said target area;
- and
- means, responsive to a change in the condition sensed by said second sensor means and said first sensor means, for indicating an intrusion.
An intrusion detection system for a mobile robot including a relatively rotatable head section and body section, the body section including drive wheels, a drive motor, and a drive system driven by the drive motor to drive the drive wheels, comprising:
- first sensor means for monitoring a first condition and second sensor means for monitoring a second condition in a space to be protected against intrusion;
- one of said sensor means being on one of said sections, the other sensor means being on the other section;
- means, responsive to a change in condition sensed by said first sensor means in a target area for aligning said second sensor means with said target area;
- and
- means, responsive to a change in the condition sensed by said first sensor means and said second sensor means for indicating an intrusion.
