Abstract

A method for providing security and maintenance of a group of devices using a group of tags. Each of the tags is attached to a device and includes a radio frequency transceiver for intercommunicating using ultra-wide band signals. Using the intercommunication, distance between two of the tags is determined and an alarm is triggered when the distance is greater than a previously defined threshold distance. The distance is preferably determined by measuring a round trip delay time between the transmission of a transmitted signal to the other tag and reception of a response signal in response to the transmitted signal from the other tag. The distance is preferably determined by measuring a time delay between transmitting a unicast ultra-wide band message and receiving a unicast response message. The intercommunication preferably uses ultra-wide band signals which relay information regarding completeness of the group between the tags of the group. A configuration mechanism is typically used for configuring the group. Upon completing the configuration, the configuration mechanism, e.g. reader or monitor, may be removed and the tags maintain the group and provide security by the intercommunication between the tags. The tags are preferably synchronized to transmit and receive solely during a previously determined periodic sequence of time intervals.

Claims

AMENDED CLAIMS [Received by the International Bureau on 04 AUG 2008 (04.08.2008)]WHAT IS CLAIMED IS:
1. A method comprising the steps of:
(a) providing a group of tags, each of said tags including a radio frequency transceiver for intercommunicating between the tags, each of said tags configured to alternate between a sleep mode and an active mode wherein a duration of said active mode is shorter than a duration of said sleep mode;
(b) using said intercommunicating, determining a distance by at least one of the tags to at least one other of the tags; and
(c) triggering an alarm when said distance is greater than a previously defined threshold distance.
2. The method, according to claim .1, wherein said intercommunicating betwean the tags is based on ultra-wide band signals.
3. The method, according to claim 1, wherein said determining of said distance is performed by at least one of said tags by measuring a round trip delay time between transmitting a transmitted signal to said at least one other tag and receiving a response signal in response to said transmitted signal from said at least one other tag.
4. The method, according to claim 1, wherein said determining is performed by at least one of said tags by measuring a time delay between transmitting a unicast ultra-wide band message and receiving a unicast ultra-wide band response message.
5. The method, according to claim 1, wherein said intercommunicating relays information regarding completeness of the group between the tags of the group.
6. The method, according to claim 1, further comprising the step of, prior to said determining:
(d) providing a configuration mechanism for configuring the group;
(e) said configuring the group of the tags by performing at least one task selected from the group of tasks consisting of (i) adding a tag to the group, (ii) removing at least one of the tags from the group, (iii) programming said at least one of the tags to intercommunicate with said at least one other tag and (iv) storing in said at least one of the tags a parameter proportional to said previously defined threshold distance.
(f) upon completing said configuring, removing said configuration mechanism, whereby said tags maintain security by said intercommunicating,
7. The method, according to claim 1, further comprising the step of;
(d) synchronizing the tags wherein, each of the tags transmits and receives during coinciding, periodic time intervals.
8. The method, according to claim 7, said synchronizing is performed by transmitting beacon signals from at least one of the tags to at least one other of the tags.
9 The method, according to claim 7, further comprising the step of:
(e) switching at least one of said tags into said sleep mode outside of said previously deternined time interval and switching to said active mode during said previously determined tune interval, thereby conserving battery power.
10. The method, according to claim 1, wherein said intercommunicating between the tags of the group includes selectably either multicast or broadcast transmitted messages, wherein, a decision by any one tag of the group to transmit within a time frame is probabilistic based on an estimate of traffic within the group.
11. The method, according to claim 1, wherein said intercommunicating between the tags of the group includes selectably either multicast or broadcast transmitted messages, wherein a decision by any one tag of the group to transmit within a time frame is deterministic according to a previously defined ordering algorithm.
12. The method, according to claim 1, wherein said intercommunicating between the tags of the group includes using unicast ultra-wide band transmitted messages and receiving unicast response messages to relay information regarding completeness of the group between the tags of the group, wherein said intercommunicating is performed during a time interval, wherein said time interval is sufficiently long so that the first tag of the group to interrogate receives an interrogation signal from the last of the group to interrogate, and wherein outside said time interval all the tags switch into a sleep mode, thereby conserving battery power.
13. The method, according to claim 1, wherein said alarm is selected from the group consisting of a sound, a light, an alarm record stored in at least one of the tags, a transmitted alarm message, and a command disabling a device operatively attached to one of the tags.
14. The method, according to claim 1, wherein said alarm is logged as an alarm record in memory of at least one of the tags, said alarm record is retrieved upon querying by a read in temporary communication with said at least one of the tags.
15. A system comprising a group of tags, each of said tags includes:
(a) a radio frequency transceiver for intercommunicating between the tags using ultra-wide band signals; wherein at least one of the tags determines a distance to at least one other of the tags using said intercommunicating, each of said tags configured to alternate between a sleep mode and an active mode wherein a duration of said active mode is shorter than a duration of said sleep mode; and
(b) an alarm mechanism, wherein said alarm mechanism selectably either triggers an. alarm or modifies operation of a device operatively attached to one of the tags, when said distance is greater than a previously defined threshold distance.
16. The system, according to claim 15, wherein said distance is determined by measuring a round trip delay time between transmitting a transmitted signal to said at least one other tag and receiving a response signal in response to said transmitted signal from said at least one other tag
17. The system, according to claim 15, further comprising a configuration mechanism operative to perform a task selected from the group of tasks consisting of: (i) adding a tag to the group, (ii) removing at least one of the tags from the group, (iii) programming said at least one of the tags to intercommunicate with said at least one other tag and (iv) storing in said at least one of the tags a parameter proportional to said previously defined threshold distance.
18. The system, according to claim 15, wherein said intercommunicating between the tags of the group includes using unicast ultra-wide band transmitted messages and receiving unicast response messages to relay information regarding completeness of the group between the tags of the group, wherein said intercommunicating is performed during a time interval, wherein said time interval is sufficiently long so that the first tag of the group to interrogate receives an interrogation signal from the last of the group to interrogate;, and wherein outside said time interval all the tags switch into a sleep mode, thereby conserving battery power.
