Abstract

A digital alerting security system and a method to signal audio and/or visual alarms and to communicate alerts through telecommunication link and/or electronic messaging that a person has forgotten or separated a predetermined distance from a valuable item/object/animal is disclosed. The system and the method also act as a smart tag to secure that travelers are accompanying their checked luggage/objects on board and to quickly identify luggage that does not belong to identified travelers on board or to facilitate their luggage retrieving afterwards by signaling and communicating alerts. The system comprises a single or multi-dimensional ultrasonic transmitter and alerting means, which is attached or integrated to the item/luggage/object/animal, with modulating and digital coding means; and a portable receiver/alerting means with demodulation and digital decoding means. Each of these means can be energized with the of aid a single pole one way switch and a power supply mean. The receiver/alerting means can automatically reset itself when the item/object/luggage/animal is secured.

frequency shift keying demodulation means to demodulate the output signal from the said amplifying means;

decoder means to decode the output signal from the said frequency shift keying demodulation means;

alerting means which is enabled from the Said decoder means in order to generate an alert when the object/item/luggage/animal to which the said transmitting means is attached, is away from the said receiving/alerting means within a predetermined range.

2. The system of claim 1 wherein said alerting means implies audio or visual alerting means to alert a person that he/she has forgotten or left behind an object/item/luggage/animal anywhere.

3. The alerting means of claim 2 wherein said audio alerting means implies a buzzer, a message player, a piece of song or music player which start to buzz, play music/song a message in a specially recognized sound and wherein said visual alerting means implies bulb/lamp which starts to flash at a recognized frequency and color.

4. The system of claim 1 wherein the alerting means implies a telecommunication link, electronic messaging or any other remote messaging means.

5. The system of claim 1 wherein the said transmitting or receiving means comprises single or multi-dimensional ultrasonic transmitting or receiving device.

6. The device of claim 5 wherein said multi-dimensional ultrasonic transmitting or receiving device comprise two half piezoelectric spheres/ellipsoids placed in a housing to leave a small gap in the middle which provides a route for connection of suitably shielded leads to both of the inner and outer surfaces of the two half spheres/ellipsoids to the alerting means of the transmitting/receiving means.

7. The device of claim 5 wherein said multi-dimensional ultrasonic transmitting or receiving devices comprises piezoelectric materials arranged in other geometric configurations such as cubical, octagon or hexagon where by an ultrasonic signal or pressure sound waves can be radiated an all directions.

8. The device of claim 5 wherein he said multi-dimensional ultrasonic transmitting or receiving means comprises multi pieces of piezoelectric material attached to membranes which are substantially arranged, in the form of a cube whereas the edges of the cube are made of rigid fixtures, all the outer surfaces of the piezoelectric pieces of material are joined together via electrical conducting leads to form an outer node and all of the inner surfaces are joined together via conducting leads to form an inner node and both of the outer node and inner nodes will be connected to the transmitted or received signal.
