The present invention describes a method of determining the location of an asset comprising the steps of: for each asset tag in the rack, exchanging identity information and location information with at least one tag of a neighboring asset, wherein at least the location information is exchanged along a substantially physically unobstructed path between the asset tag and it's at least one neighboring asset tag; for each asset tag, transmitting the identity information and location information exchanged to a collection unit; and responsive to the information transmitted to the collection unit determining the location of the asset relative to other assets.

A method and system for providing secure communications between a first and second peer device is disclosed. The invention includes allowing the first and second peer devices to verify the authenticity of each other only while each peer device is within an established zone of privacy wherein the established zone of privacy is an area close (for example, almost touching) to the peer device. Because the authenticity of the other device is verified only while each peer device is within the established zone of privacy, users can visually confirm that there are no potential interlopers within the zone. As a result, the two peer devices can discover each other in a more secure fashion The method and system include creating a zone of privacy with the first peer device, allowing the first and second peer devices to verify the authenticity of each other only while the second peer device is within the zone of privacy, and allowing encrypted data to transfer between the first and second peer device once the authenticity of each peer device has been verified.

A system for tracking RFID tags with a reader device having a plurality of antennas. The antennas are positioned such that portions of at least two of the plurality of antennas physically overlap each other and are in approximately the same plane. A pair of overlapping antennas are also positioned so that an RFID tag is positioned within both signal fields of the pair of overlapping antennas. In addition, the reader device is configured to selectively activate the plurality of overlapping antennas to thereby selectively interrogate one or more of the RFID tags, and the reader device is configured to use the selective interrogation of the one or more RFID tags to track the locations of the RFID tags.

A multi-tiered network for gathering detected condition information includes a first tier having first tier nodes and a second tier having a second tier node. The second tier node is operable to receive detected condition information from at least one of the first tier nodes in a substantially autonomous manner. In addition, the second tier node is operable to at least one of store, process, and transmit the detected condition information. The network also includes a third tier having a third tier node configured to receive the detected condition information and to at least one of store and process the detected condition information.

A method and versatile device for use-based context security is described. In an embodiment, the versatile device is implemented as a wristwatch. The wristwatch is configured to facilitate a wireless transaction for an authenticated user and is configured to be worn by the authenticated user such that to encircle a part of the authenticated user. Moreover, the wristwatch includes a validation mechanism for controlling use of the wristwatch based on whether the authenticated user continues to wear the wristwatch after initiating use of the wristwatch.

A power control circuit is used to control the power supplied to a circuit from a power source. The power control circuit is operable to connect and disconnect the power source from the circuit. The power control circuit connects the power source to the circuit in response to an externally applied magnetic field.
