Systems and techniques for vandalism detection in a personal communication structure (PCS)
First Claim
1. A personal communication structure (PCS) comprising:
- one or more vandalism detection systems;
each vandalism detection system comprising an accelerometer for;
detecting a series of forces applied to the PCS during a time period;
determining if the detected forces are attributed to environmental effects, wherein the determination of whether the detected forces are attributed to environmental effects comprises determining the frequency of the forces applied to the PCS and comparing the frequency of the forces applied to the PCS to frequencies associated with environmental effects; and
if not attributed to environmental effects, issuing an alert indicating the PCS is being subject to an act of vandalism.

Abstract
Systems and techniques for vandalism detection in a personal communication structure (PCS) are described. The PCS may include one or more vandalism detection systems which may be located in different system compartments of the PCS. Each vandalism detection system may include (or being communicatively coupled to) an accelerometer and may be able to differentiate forces associated with acts of vandalism from other forces. The vandalism detection systems may transmit alerts with accompanying data to a remote entity. The data allows for an appropriate response to the alert. The alert may be transmitted to a remote security center over a wired or wireless communications system. The controller may transmit the alert again or to other locations if an acknowledgement is not received.

14. A method for detecting vandalism at a personal communications structure (PCS), the PCS including one or more vandalism detection systems, the method comprising:
-
detecting, using an accelerometer, one or more series of forces applied to the PCS during a time period; determining if the detected forces are attributed to environmental effects, wherein the determination of whether the detected forces are attributed to environmental effects comprises determining the direction of the forces applied to the PCS, and wherein the detected forces are more likely to be attributed to environmental effects if the direction of the detected forces is parallel to a display surface of the PCS rather than orthogonal to the display surface of the PCS; and if not attributed to environmental effects, issuing an alert indicating the PCS is being subject to an act of vandalism. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
