  • Patent number: 8830033
    Abstract: An active EMI shield for protecting medical instruments from mobile RF emitters uses RFID tags and tag readers to facilitate identification of an RF emitter entering the EMI shield. Clinicians and mobile RF emitters are tagged with RFIDs that indicate their identity, and possibly RF power level. Medical instruments are either tagged with RFIDs that indicate their identity and susceptibility to EMI, or equipped with RFID readers/EMI sensors. The proximity of the RF emitter relative to the medical instrument in terms of power density can then be determined by either position-sensitive RFID readers or the EMI sensors affixed to the medical instruments. The shield is executed by signaling to the tagged RF emitter when it reaches a predetermined proximity relative to the medical instrument.

  • Patent number: 8727216
    Abstract: A portable memory module, which comprises an interface allowing the module to be connected to and disconnected from an electronic device by a user of the module such that the electronic device is in close physical proximity to the module when connected thereto; memory storing an identifier of the module; an emitter; and a processing entity configured to encode the identifier of the module into a signal that is transmitted via the emitter as a wireless beacon. The memory contains information that allows the module to be identified by an entity connected to the electronic device. The wireless beacon is configured to enable a location of the module to be determined by a detection sub-system. When the module is connected to the electronic device and the identity of the module is transmitted to a network entity via the electronic device, the location of the module can be used by the network entity to establish the location of the electronic device.

  • Publication number: 20140019640
    Abstract: System and method for dynamically re-directing communications sessions destined for a particular entity in a communications system, each communications session being associated with at least one predefined route. Location information indicative of a current location of the particular entity is obtained and applied to a predefined set of conditional routing rules associated with the particular entity. This rules-based processing generates a routing result, on the basis of which the at least one predefined route associated with each communications session destined for the particular entity is dynamically updated.

  • Patent number: 8073554
    Abstract: The present invention relates to a system and method for providing power management to sensing nodes in a sensor network. A system may include a plurality of sensing nodes, each sensing node connected through a power management device to an external power source, such as a powered node of another network, for managing power from the external power source to the sensing node. Beneficially, a plurality of power management devices allow for a sensor network of fixed or mobile wireless sensing nodes or sensor gateways to make use of power from an external source such as an another network e.g. an existing emergency lighting system or other similar powered building system. Thus for example, a sensor or group of sensing nodes and their associated power management devices may be integral with or co-located in proximity to powered nodes of these other networks.
