Signal generation system and method for generating signals
First Claim
1. A signal generation system, comprising:
- an enclosure having a door, said door being pivotable between a fully open position and a closed position;
at least one piezoelectric device which, upon actuation, generates voltage; and
at least one wireless transmitter which generates a wireless signal when said piezoelectric device generates said voltage,said piezoelectric device comprising a spring-loaded pushbutton, a hammer and at least one piezoelectric element, said pushbutton having a first pushbutton position and a second pushbutton position,wherein;
upon moving said door to said closed position, said pushbutton is moved from said first pushbutton position to said second pushbutton position, and upon moving said door away from said closed position, said pushbutton is moved from said second pushbutton position to said first pushbutton position, andsaid hammer is actuated to exert pressure on said piezoelectric element and thereby actuate said piezoelectric element when said pushbutton is moved from at least one of said first pushbutton position and said second pushbutton position to the other of said first pushbutton position and said second pushbotton position.

Abstract
A signal generation system, comprising a piezoelectric device which, upon actuation, generates voltage, and a wireless transmitter which generates a wireless signal when the piezoelectric device generates the voltage. A signal generation system, comprising signal generating devices, each wireless transmitter generating a respective signal comprising transmission which identifies the wireless transmitter. A signal generation system, comprising signal generating devices, each of the signal generating devices being mounted in or on respective structures which are free to move any distance relative to each other. A method of generating a signal, comprising actuating a piezoelectric device to generate an electrical signal, conveying the signal to a wireless transmitter, and transmitting a wireless transmission. A method of monitoring, comprising actuating piezoelectric devices in signal generating devices to generate respective electric signals, conveying the signals to corresponding wireless transmitters and transmitting corresponding wireless transmissions, each wireless transmission identifying the corresponding piezoelectric device.

13. A signal generation system, comprising:
-
a plurality of enclosures, each said enclosure having at least one door, each said door being pivotable between a closed position and a fully open position; a plurality of signal generating devices, each signal generating device comprising; at least one piezoelectric device which, upon actuation, generates voltage; and at least one wireless transmitter which generates a wireless signal when said piezoelectric device generates said voltage, each wireless transmitter generating a respective signal, each respective signal comprising transmission which identifies the specific wireless transmitter from which said respective signal was generated, wherein; each said signal generating device being mounted on one of said enclosures such that for each enclosure, upon moving at least one door attached to said enclosure away from said closed position or to said closed position, a piqzoelectric device in a signal generating device mounted on said enclosure is actuated and generates a voltage, causing a wireless transmitter in said sinai aenerating device to generate a wireless signal indicating that said enclosure has been manipulated and identifying said enclosure. - View Dependent Claims (14, 15)

16. A method of generating a signal, comprising:
-
moving a door which is pivotably mounted on an enclosure to a closed position or away from a closed position, thereby moving a sprinaloaded pushbutton from a first pushbutton position to a second pushbutton position or from said second pushbutton position to said first pushbutton position, said moving said pushbutton causing a hammer to actuate to exert pressure on a piezoelectric device to generate a signal, said signal being electrical; conveying said signal to a wireless transmitter; and transmitting a wireless transmission from said wireless transmitter when said wireless transmitter receives said signal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
