Claims
- 1. A wake-up circuit for use in a security pack comprising an alarm device and an electronic activation circuit for said alarm device in a packet resembling a currency pack, wherein said wake up circuit comprises a flexure sensor adapted to switch the electronic alarm activation circuit from a first, dormant state to a second, active state.
- 2. The wake up circuit of claim 1 wherein said electronic activation circuit comprises a microprocessor, wherein said flexure sensor is connected to said microprocessor and wherein an output signal from said sensor received by said microprocessor switches the electronic alarm activation circuit from said first, dormant state to said second, active state.
- 3. The wake up circuit of claim 2 wherein said security pack is a flexible pack and said sensor generates an output signal when said pack is flexed.
- 4. The wake up circuit of claim 1 wherein said security pack includes a power source and wherein said sensor comprises a switch connected between said power source and said electronic alarm activation circuit.
- 5. The wake up circuit of claim 2 wherein said security pack comprises at least two printed circuit boards with discreet electronic components thareon and wherein said sensor comprises a flexure sensing transducer and said transducer is positioned straddling more than one of said boards.
- 6. The wake up circuit of claim 4 wherein said security pack comprises a flexible printed circuit with a plurality of discreet electronic components and wherein said sensor comprises a flexure sensing transducer and said transducer is positioned straddling more than one of said discreet components.
- 7. The wake up circuit of claim 5, wherein said transducer is flexible.
- 8. The wake up circuit of claim 5, wherein said transducer is a piezoelectric transducer.
- 9. The wake up circuit of claim 1, wherein said sensor comprises a flexure sensing transducer and wherein said transducer is a piezoelectric transducer.
- 10. The wake up circuit of claim 1, wherein said sensor comprises a flexure sensing transducer and wherein said transducer is a variable resistive element.
- 11. The wake up circuit of claim 1, wherein said sensor comprises a flexure sensing transducer and wherein said transducer is a capacitive element.
- 12. A method for waking up a security pack comprising an alarm device and an electronic activation circuit for said alarm device in a flexibly packet resembling a currency pack, wherein said wake up circuit comprises a flexure sensor adapted when flexed to switch the electronic alarm activation circuit from a first, dormant state to a second, active state the method comprising flexing the security pack to wake up the electronic activation circuit for said alarm device.
- 13. A method for switching an electronic activation circuit for an alarm device contained in a flexible currency resembling security pack the method from a standby state to an active state, the method comprising:
(a) providing a flexure sensor; (b) sensing a package flexure with said sensor; (c) generating a signal indicative of said package flexure; (d) applying said signal to switch said electronic activation circuit for said alarm device from said standby state to said active state.
- 14. The method of claim 13 wherein said step of applying said signal to switch said electronic activation circuit to said active state further comprises connecting an output of a power source to an input of said electronic activation circuit.
