Abstract: Various technologies described herein pertain to controlling migration of a source endpoint in a source telephony system to a destination endpoint in a destination telephony system. The source endpoint is deactivated and the destination endpoint is activated as part of the migration. The migration of endpoints between the source telephony system and the destination telephony system can be performed in an individualized manner. Source information that specifies a state of the source endpoint is retrieved from the source telephony system and destination information that specifies a state of the destination endpoint is retrieved from the destination telephony system. Moreover, a validation is performed concerning whether the source endpoint is migratable to the destination endpoint based on the source information and the destination information.

Abstract: A system is provided for delivery of services to at least one mobile device adapted to communicate in a wireless manner including a plurality of communication/detection devices. Each of the communication/detection devices is adapted to detect the presence of the mobile device when the mobile device is within the range thereof. Each communication/detection device is adapted to communicate information between the mobile device and the communication/detection device when the mobile device is within the range thereof. The system includes at least one multiplexer in communication with at least one of the communication/detection devices and at least one server including content stored thereon to provide at least one service to the client program on mobile device. The server is in communication with the multiplexer. The service to be provided to the mobile device depends on which one of the plurality of communication/detection devices is in communication with the mobile device.

Abstract: A wireless resource monitoring system and method utilizes a network of deployed radio elements including at least one master radio, a plurality of beacons, and at least one tag. The beacons are placed at known positions. The master radio, the beacons and the tag are in wireless communication with each other. The tag is attached to the resource that is being monitored. A beacon signal is transmitted by the beacons, which includes the identity of the transmitting beacons. The tag receives the beacon signals and measures the signal strength of the beacon signals. The tag then transmits a tag signal, which includes the identity of the transmitting tag, the measured signal strengths of the beacon signals and the identity of the corresponding beacons. The location of the tag is then determined from the tag signal.

Abstract: An antenna that includes, in at least one embodiment, first and second radiating elements each having a substantially conical radiating surface. Each radiating surface may be substantially linearly conical or nonlinearly conical. The radiating surfaces are substantially aligned coaxially, and the radiating elements are positioned on opposing sides of a signal launching region, extending in opposing directions from the signal launching region. A signal feed extends through the first radiating element, thereby positioning a signal launch point between the first and second radiating elements in the signal launching region proximate vertices of the first and second radiating surfaces. The first and second radiating elements have first and second included angles, respectively, that are each no less than about 40 degrees.

Abstract: A radio frequency (RF) system and method for determining the location of a wireless node in a wireless mesh sensor network is disclosed. The wireless node can be a wireless terminal, a wireless transceiver, or a wireless transmitter. The wireless network includes a plurality of wireless nodes linked to a digital computer, such as, for example, a server or a location processor, via a communications link. The method comprises deploying a plurality of identifier wireless nodes each at a predetermined location. Node-to-node data for the wireless nodes are generated, the node-to-done data providing information regarding a wireless node's communication with other wireless nodes. The node-to-node data is transmitted to the digital computer where the node-to-node data is processed to generate a map identifying the locations of the wireless nodes.

Abstract: Provided is an antenna. In one example, the antenna includes a base having a substantially planar upper surface with an axis perpendicular to the upper surface. The base forms a ground plane for the antenna. The antenna also includes at least three conductive planar elements that are substantially triangular and are electrically coupled to the base via a feed point. Each element has a vertical edge oriented parallel to the base's axis and a horizontal edge oriented parallel to the upper surface. An angle formed by the intersection of the vertical and horizontal edges of each element is located on the base's axis and is distal from the feed point. The elements are positioned equidistantly from the base and equiangularly from one another. The vertical edges of the elements are coupled along the base's axis to form a contiguous conductive surface that is a driven element of the antenna.

Abstract: An apparatus and method for coupling energy from a transmission line is provided. The apparatus includes a contact designed to “tap” into an inner conductor of the transmission line 100 through an aperture in an outer conductor of the transmission line. A portion of the contact may be coiled (e.g., a spring) and the coil's characteristics may be varied to control the insertion loss and coupling loss of the apparatus. For example, the wire size, coil diameter, number of turns, and pitch design of the coil may be controlled. The apparatus may also include a secondary transmission line connected to the coil and the secondary transmission line may allow additional control over the coupled energy.

Abstract: A coupler for coupling a selected amount of energy from a transmission line 100 includes a contact 104 for contacting an inner conductor 102 of transmission line 100 through an aperature through an outer conductor of transmission line 100. A wire 106 of a preselected configuration is coupled to contact 104 and is spaced from a ground plane 108 to create a selected parasitic capacitance, the configuration of wire 106 defining a center frequency of the coupler. Coupler also includes a connector 110 having an inner conductor 111 coupled to wire 106.
