Abstract

A lock system having a remote actuating key device, e.g., a portable member arranged to wirelessly transmit a wireless signal, and a passive lock device for receiving that signal. The lock device includes an actuatable trigger mechanism and a control circuit. The control circuit receives the wireless signal, which powers it. The control circuit also determines if the wireless signal is appropriate to unlock the lock, whereupon it produces a trigger signal. The trigger mechanism is responsive to the trigger signal to actuate and enable the lock device to be opened. The key device is also arranged to communicate via a wireless communications connection to a computer network. The communication with the computer network may carry commands and information. The key device may relay communications between the lock device and the computer network.

1. A lock system comprising:

a remote actuating key device which comprises a portable member arranged to wirelessly transmit at least one radio frequency signal;

a passive lock device which comprises an actuatable trigger mechanism coupled to a control circuit, and wherein said control circuit is adapted to receive said at least one radio frequency signal for electrically powering said control circuit, and for determining if said signal is appropriate to unlock said lock device, said control circuit also generating a trigger signal if said signal is determined to be appropriate, said trigger signal being received by said trigger mechanism which activates said trigger mechanism to enable said lock device to be unlocked; and

a computer network, wherein said computer network and said key device are adapted to communicate via a wireless communications connection.

2. The lock system of claim 1 wherein said key device is further adapted to be enabled or disabled upon receipt of an appropriate communication received from said computer network.

3. The system of claim 1 wherein said key device further comprises a user interface, and wherein the key device is further arranged to require a user to enter a code to enable operation of said key device.

4. The system of claim 3 wherein said code required of the user is varied in accordance with an algorithm stored with said key device.

5. The system of claim 3 wherein said code required of the user is varied in accordance with an appropriate communication from said computer network.

6. The system of claim 3 wherein said computer network is further arranged to issue a communication to enable or disable said key device based upon an outcome of a dialogue between said key device and said computer network, and wherein said key device is arranged to facilitate said dialogue.

7. The system of claim 1 wherein said control circuit is further adapted to make inquiries of said key device whereby said lock device may authenticate an identity or authority of said key device in order to determine if said at least one signal is appropriate to unlock said lock device.

8. The system of claim 7 wherein said key device is further adapted to communicate with said computer network to obtain required responses to inquiries made by said lock device.

9. The system of claim 8 wherein said key device is further adapted to provide a communication channel whereby a dialogue may occur between said lock device and said computer network in which messages between said lock device and said computer network are relayed by said key device.

10. The system of claim 9 wherein said dialogue between said lock device and said computer network are encrypted for preventing interception by said key device or other message relaying devices.

11. The system of claim 1 wherein a code required of said key device to unlock said lock device is varied in accordance with an algorithm stored within said lock device.

12. The system of claim 11 wherein said algorithm makes use of a variable selected from the group consisting of:

(a) a date;

(b) a time;

(c) a provenance of said lock device;

(d) a provenance of said key device;

(e) a random number;

(f) a serial number of said lock device; and

(g) a serial number of said key device.

13. The system of claim 1 wherein said key device is further adapted to record when said lock device has been unlocked and to record when said lock device is later relocked, and to record an error or activate an alarm whenever a period of time between unlocking and locking of said locking device exceeds a predetermined period of time.

14. The system of claim 1 wherein said control circuit uses a matrix of permission criteria when determining if said signal is appropriate, said control circuit permitting a second key device to gain access to said lock device using a second signal different from said at least one radio frequency signal.

15. The system of claim 1 wherein said control circuit uses a provenance of said key device to determine if said signal is appropriate.

16. The system of claim 1 wherein said control circuit uses a provenance of said lock device to determine if said signal is appropriate.

17. A method of protecting a structure by use of a lock system comprising:

(a) coupling a passive lock device to a structure for protecting the structure;

(b) wirelessly transmitting at least one radio frequency signal from a remote actuating key device which includes a portable member;

(c) receiving said at least one radio frequency signal by a control circuit of said passive lock device for electrically powering said control circuit;

(c) determining, by said control circuit, if said at least one radio frequency signal is appropriate to unlock said passive lock device, and generating a trigger signal, by said control circuit, for receipt by an actuatable trigger mechanism coupled to said control circuit if said at least one radio frequency signal is determined appropriate and not generating said trigger signal if said at least one radio frequency signal is determined not appropriate by said control circuit;

(e) enabling said lock device to be unlocked by said trigger mechanism when said trigger signal is received by said trigger mechanism; and

(f) communicating, by said remote actuating key device, with a computer network via a wireless communication network.

18. The method of claim 17 wherein said key device is enabled or disabled upon receipt of an appropriate communication received from said computer network.

23. The method of claim 17 wherein said control circuit makes inquiries of said key device whereby said lock device may authenticate an identity or authority of said key device in order to determine if said at least one signal is appropriate to unlock said lock device.

24. The method of claim 23 wherein said key device communicates with said computer network to obtain required responses to inquiries made by said lock device.

25. The method of claim 24 wherein said key device provides a communication channel and whereby a dialogue occurs between said lock device and said computer network in which messages between said lock device and said computer network are relayed by said key device.
