Patent for Sale:

Position Change Sensing Anti-Theft Device    

The invention is related to position change detection techniques, especially suitable for theft prevention of valuable items.

Overview

The patent discloses methods of emitting, receiving and analyzing specific audio signals, for detecting unauthorized movement of a protected item and consequently activating an alarm.

The technology has significant advantages over motion sensing alarms and other traditional theft prevention methods, such as cables and locks. It is simple to use, reliable and efficient, and detects any theft attempt the moment the item is displaced from its initial position, no matter how slow the movement is.

For some applications, such as protecting laptops, notebook computers, tablet PCs, smartphones and digital cameras, all necessary hardware is already part of the items, therefore the technology can be implemented in software only. This feature allows physical protection (of the item and, more important, the stored data) at a very low cost, since the cost of extra electronics components is eliminated.

Primary Application of the Technology

Theft prevention of:
- laptops
- notebook computers
- tablet PCs
- smartphones
- digital cameras
- briefcases
- art pieces
- valuable items in general

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 340: Communications: Electrical

Communications - the handling of information or intelligence, restricted to the conveying of said information or intelligence between geographically spaced points. Information or intelligence is defined as being, matter which is handled by signaling systems or signaling devices (such as telegraph systems) or by that portion of nonsignaling systems or nonsignaling devices (such as power supply systems) which is designated in the arts as having a control function (such as the supervisory circuits which control the circuit breakers of an electric power network). Handling, as used above, is defined as being the active coaction between the tangible communication system or device and the intangible information or intelligence, and such coaction may assume various forms, such as transmission, storage, exhibiting, etc.

Subclass 539.1: Radio
Subclass 568.1: Article placement or removal (e.g., anti-theft)
Subclass 571: Alarm on protected article

Class 367: Communications, Electrical: Acoustic Wave Systems And Devices

The communication of information or intelligence in the form of travelling stresses in an elastic medium which are detected or generated by electric signal handling means wherein the electric signal represents the communicated information or intelligence.

Subclass 93: Presence or movement only detection
