An identification tag has at least a controller, a receiver for receiving wireless signals from an exciter, and a transmitter for transmitting wireless signals to at least one location receiver (which may be a WLAN access point). The tag's controller can determine the presence of interference from sources unrelated to the location system, such as smartphones, tablets, computer monitors etc., and signal an alert accordingly.

Enhanced wireless location system and method

A method and system is provided that may be used to dynamically modify membership of a collaboration group participating in a collaboration session using dynamic situational information associated with collaboration session and/or collaboration group member candidates. The dynamic situational information may include collaboration session information, environmental information and context information. A change in collaboration session purpose may trigger a modification of group membership in accordance with a concomitant change in group membership criteria. A change of situational information associated with any group member candidate may trigger the modification of group membership, to add or delete the candidate from the group. The method and apparatus of the present invention may advantageously be embodied in a service that is used by existing communication and collaboration systems to enhance workflow efficiency by exploiting system knowledge to improve the use of resources, reduce the incidence of errors and eliminate redundancy.

A mobile backhaul inter-mesh communication point forms an interface between a wireless mesh network on a first level and a wireless mesh network on a second, higher bandwidth, level. The two wireless networks are differentiated, e.g., by causing the mesh networks to be formed using different spectra, protocols or coding, or antennae. The mobile intra-mesh communication point functions as an access point in the lower level mesh network and as a relay point in the upper level mesh network. Utilizing mobile inter-mesh communication points facilitates deployment of wireless network access points while enabling the location of access points to follow the concentration of network users. Mobile inter-mesh communication points may be deployed in personal vehicles such as cars, trucks, and motorcycles, public transportation vehicles such as busses, trains, and aircraft, emergency vehicles such as fire trucks and ambulances, and many other types of vehicles.

Security information such as fixed or dynamically received camera location information, laser signature information, timestamp information, and network information, may be used to secure the transport and storage of surveillance video. Where the surveillance video is to be transported on a communication network, the round trip time from a video data storage server to the surveillance camera and back to the video data storage server may be monitored and periodically added to the secured video data. By checking to see whether the round trip time has changed, it may be possible to determine whether the video has been tampered with. The secured video data may also be transported over two or more paths on the network to two or more video data storage servers so that redundant copies may be stored at different primary locations. By comparing copies of the data, alteration of one of the copies may be detected.

A system and method for preventing e-mail spoofing, in which a receiving e-mail checking server system sends a message to a confirmation server associated with a network domain of the sending system of a received e-mail message, to determine if the sender transmitted the message. The e-mail checking server sends a confirmation request e-mail, including a transmission time or unique message 'key' associated with the received e-mail, to the sending domain's confirmation server. When a confirmation request is received at the confirmation server, it replies with an indication whether the message was sent at the time indicated in the confirmation request, and/or whether the message key matches that of a previously transmitted message. The confirmation server checks whether the message was in fact sent based on stored values corresponding to the send time and/or message key stored for the confirmation request message. A message may further include indication that its origin can be confirmed. A receiver may maintain indications of domains capable of confirming sent e-mail messages, and determine a problem has occurred if no confirmations are received from a domain having that capability. An e-mail sender may mark domains from which it expects to receive e-mail confirmation requests, and determine a problem has occurred if e-mail messages sent to such domains fail to send confirmation requests.

A method and system for managing handover where a database that receives location information about a moving object includes information regarding which base station is used in a current radio link connection and which base stations were used from historic radio link connections. Using the base station radio link history of the object and an electronic map, a processor selects which physical path the moving object is using. Upon matching the object's path with a history of path routes on the list, the processor will apply an optimized handoff sequence to the moving object. The optimized route can be derived from an algorithm that processes previous historical data from moving objects traveling on the same route.

System and method for determining location-enhanced presence information for a particular entity subscribed to a communications system. Location information indicative of a current location for the particular entity is obtained, as well as presence information indicative of a current activity status of the particular entity within the communications system. A combination of the current location and current activity status of the particular entity is applied as a condition to a set of conditional rules associated with the particular entity, for determining current location-enhanced presence information for the particular entity.

The rate at which a particular wireless client may be PINGed may depend on many factors, including the accuracy with which the location of the wireless client is required to be known, how accurate the system has historically been able to locate other previous clients in the same general area; the speed with which the client is moving, the amount of other data being transmitted by the client, the needs of other clients being serviced by the access point that will need to PING the client, the current battery life of the client, and the priority of obtaining an accurate location for a particular wireless user verses other uses of the network bandwidth. Based on the multiple factors considered by the system, the rate at which the client will be PINGed is adjusted to optimize the amount of bandwidth used to determine the client's location.

A method and system for managing handover where a database that receives location information about a moving object includes information regarding which base station is used in a current radio link connection and which base stations were used from historic radio link connections. Using the base station radio link history of the object and an electronic map, a processor coupled to the memory of the database selects which physical path the moving object is using. Upon matching the object's path with a history of path routes on the list, the processor will apply an optimized handoff sequence to the moving object. The optimized route can be derived from an algorithm that processes previous historical data from moving objects traveling on the same route. Methods of providing the location of moving objects via location sensors may be used to provide the database with higher resolution information about a moving object's location on an electronic map and allow further enhancement of the handoff optimization. Generally, location data is used to quickly determine which route the moving object is using and more quickly assign an optimized handoff sequence. Historical data along known routes can include time and spatial information to be processed by the routing algorithm. The database may reside in a central location or within each moving object or a combination of both.

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. An intelligent power management device connected to at least one of the sensing nodes may provide for power policy management to sensing nodes based on monitoring power conditions such as available power, power level status, and information obtained from the sensing nodes indicative of network conditions, detecting a change therein, and regulating power to the sensing node depending on the change.
