Portable alarm system
A portable alarm system is disclosed. The portable alarm system includes a portable base station, which has an outer housing that encloses a power supply and a secondary protective housing. The secondary protective housing encloses at least a controller and a cellular modem that are electrically connected to each other. An energy storage device, such as a super capacitor, is configured to maintain a store of energy and is electrically connected to the controller and the cellular modem to provide an alternative power source thereto.
1. A portable alarm system for identifying an intrusion to a physical premise, comprising:
a portable base unit, including an outer housing that encloses a receiver, a power supply and a secondary protective housing, the receiver configured to receive a wireless alarm signal indicative of a physical intrusion from at least one sensor that is physically separate from the portable base unit;
a controller enclosed in the secondary protective housing that is configured to receive primary power from said power supply and to communicate with the wireless receiver;
a cellular modem enclosed in the secondary protective housing that is electrically connected to the controller and that is configured to receive primary power from said power supply; and
an energy storage device enclosed in the secondary protective housing that is configured to maintain a store of energy and that is electrically connected to the controller and the cellular modem to provide a back-up source of power thereto upon detection by the controller that said power supply has been permanently eliminated.
2. The portable alarm system of claim 1 , wherein said energy storage device is chosen from the group consisting of a super capacitor and an ultra-capacitor.
3. The portable alarm system of claim 1 , wherein said secondary protective housing is comprised of a polycarbonate material.
4. The portable alarm system of claim 1 , further comprising an accelerometer enclosed within the outer housing and in electrical communication with said controller.
5. The portable alarm system of claim 1 , further comprising a pressure transducer enclosed within the outer housing and in electrical communication with said controller.
6. The portable alarm system of claim 1 , further comprising a metalized membrane secured to an inside surface of said outer housing, wherein said metalized membrane comprises at least two metalized layers, wherein said power supply causes an electrical potential to be applied between them.
7. The portable alarm system of claim 1 , wherein said secondary protective housing is watertight.
8. A portable alarm system for identifying an intrusion to a physical premise, comprising:
a portable base unit, including an outer housing that encloses a receiver, a power supply and a secondary protective housing, the receiver configured to receive a wireless alarm signal indicative of a physical intrusion from at least one sensor that is physically separate from the portable base unit;
a controller enclosed in the secondary protective housing that is configured to receive primary power from said power supply;
a wireless communications device enclosed in the secondary protective housing that is in communication with said controller and that is configured to receive primary power from said power supply; and
an energy storage device enclosed in the secondary protective housing that is configured to maintain a store of energy and that is electrically connected to the controller and the cellular modem to provide a back-up source of power thereto upon detection by the controller that said power supply has been permanently eliminated.
9. The portable alarm system of claim 8 , wherein said energy storage device is chosen from the group consisting of a super capacitor and an ultra-capacitor.
10. The portable alarm system of claim 8 , wherein said secondary protective housing is comprised of a polycarbonate material.
11. The portable alarm system of claim 8 , further comprising an accelerometer enclosed within the outer housing and in electrical communication with said controller.
12. The portable alarm system of claim 8 , further comprising a pressure transducer enclosed within the outer housing and in electrical communication with said controller.
13. The portable alarm system of claim 8 , further comprising a metalized membrane secured to an inside surface of said outer housing, wherein said metalized membrane comprises at least two metalized layers and wherein said power supply causes an electrical potential to be applied between them.
14. The portable alarm system of claim 8 , wherein said secondary protective housing is watertight.
15. The portable alarm system of claim 1 , wherein said controller is configured to cause said cellular modem to transmit a wireless signal upon detection of an external act of abuse against said base unit.
16. The portable alarm system of claim 8 , wherein said controller is configured to cause said cellular modem to transmit a wireless signal upon detection of an external act of abuse against said base unit.
17. The portable alarm system of claim 4 , wherein said controller is configured to cause said cellular modem to transmit a wireless signal in response to receiving a signal from said accelerometer indicative of movement of said base unit.
18. The portable alarm system of claim 5 , wherein said controller is configured to cause said cellular modem to transmit a wireless signal in response to receiving a signal from said pressure transducer indicative of a change in pressure inside of said outer housing.
19. The portable alarm system of claim 6 , wherein said controller is configured to cause said cellular modem to transmit a wireless signal in response to receiving a signal indicative of a change in the electrical potential between said two metalized layers.
