Abstract: A communications system has stations arranged in clusters (1a, 1b and 1c) of communication member stations (CM2, CM3, CM6 and CM7), with one member station (CH1, CH4 or CH5) in each cluster being a head station for the cluster. Each member station (CM2, CM3, CM6 and CM7) communicates with the network through a cluster head station (CH1, CH4 or CH5). The cluster head stations (CH1, CH4 and CH5) communicate among other cluster head stations (CH1, CH4 and CH5). A mobile communications station (e.g., CM3) evaluates a beacon message received from a first member station (e.g., CM6) of the plurality of mobile stations through a transceiver 6. The station CM3 also determines whether to communicate with the first member station CM6 directly or to communicate with the first member station CM6 by forwarding messages through a cluster head station CH1 that is affiliated to the mobile communications station CM3.

Abstract: An observation system for observation calls to a call center includes an automatic call director (ACD) unit, an interactive voice response (IVR) unit, and a recorder unit. The ACD receives incoming calls to the call center and also queues and switches the calls to various lines of the call center. The IVR unit is connected to the ACD unit and interacts with a caller via an interactive computer program in which the caller enters a response to a prompt and the response causes the interactive program to provide the caller with information or another prompt. The recorder unit records calls to the call center from beginning to end, including prompts made by the IVR unit, callers responses to the prompts, and information provided by the IVR unit to the callers.

Abstract: A method can change transmit schedules in an ultra-wideband radio network by collecting traffic flow information from the nodes in the network, calculating new schedules that can be based on the traffic flow information and that can maintain traffic collisions on the network below predetermined levels, disseminating the new schedules to the network nodes and synchronizing a switch to the new schedules. The calculations for the new schedules can employ “hard” problem solution techniques, such as simulated annealing, genetic algorithms, complete searches and heuristics.

Abstract: A speech recognition system (105) includes an acoustic front end (115) and a processing unit (125). The acoustic front end (115) receives frames of acoustic data and determines cepstral coefficients for each of the received frames. The processing unit (125) determines a number of peaks in the cepstral coefficients for each of the received frames of acoustic data and compares the peaks in the cepstral coefficients of a first one of the received frames with the peaks in the cepstral coefficients of at least a second one of the received frames. The processing unit (125) then segments the received frames of acoustic data based on the comparison.

Abstract: A method of communication is provided in which a node maintains a condition table which includes at least one condition unrelated to network traffic conditions, which if met triggers the node to reserve a set of time windows for receiving communications. During those time windows, the node refrains from initiating transmission of communication.

Abstract: According to the principles of the invention, there is provided a system, apparatus, and method for detecting spurious network traffic. In a system according to the principles of the invention, a switch such as a router constructs a routing tree for each other switch connected thereto. When a network packet is received, the switch inspects the source address of the packet, and determines whether the forwarding switch or network interface could be expected to deliver a network packet from the indicated address. If it appears from this analysis that the network packet should not have come from the forwarding switch, then certain measures may be taken to address the situation. For example, the network packet may be dropped, an alarm may be generated to the forwarding switch, or an alarm may be generated to an automated or human network supervisor.

Abstract: A method ensures that a set of anonymous peer devices (110) and anonymous policy servers (120) in a system (100) are apprised of all current versions of a policy so that they can quickly implement a version of the policy as it becomes active. The method includes determining whether new versions or a newly active version of a policy exists and generating a message containing the newly received or newly active policy version(s). The method also includes transferring the message to the peer devices (110), the transfer being initiated by either the sender or the receiver.

Abstract: An optical transmitter includes a transmitting unit and a processing unit. The transmitting unit transmits multiple optical synchronization pulses at a first intensity, and transmits multiple optical quantum cryptographic key distribution (QKD) pulses at a second intensity. The processing unit encodes a cryptographic key symbol in a quantum state of each QKD pulse of the QKD pulses, and delays transmission of each of the multiple optical synchronization pulses a derived interval after transmission of a corresponding one of the multiple QKD pulses.

The system also includes an analysis device (140) that monitors and analyzes the nodes (135-1 to 135-N) during the protocol testing.

Abstract: Schemes for routing a call using caller identification are described herein. These schemes are termed “real caller ID” and can be capable of determining the identity of a calling party independent of a telephone number from which the call originated. According to one exemplary embodiment, a method of routing a call from a calling party to a receiving party may include accessing a database containing a plurality of voice templates of prior calling parties. Each voice template may have correlated therewith a call disposition parameter defined by the receiving party. Next, a voice response from the calling party may be compared with one of the plurality of voice templates stored in the database. Subsequently, the call may be routed to the receiving party based on a match between the voice response and the one of the plurality of voice templates.

Abstract: An apparatus and method are provided for the in-situ measurement of the stiffness of a layer of soil or other surface of interest. The apparatus includes a contact foot for engaging the surface and a drive transducer coupled to the contact foot for applying a vibratory force to the contact foot in response to a drive signal. A motion sensor is coupled to the contact foot and in a preferred embodiment an additional sensor measures the force applied to the contact foot and hence to the surface. These sensors generate corresponding output signals. The output signals are used to generate a measurement signal that is representative of the surface stiffness.

The information describes network operation over a period of time. The system then reconstructs the network operation for the time period from the collected information (520) and presents the reconstructed network operation to an operator (530-550).

Abstract: A method and apparatus is disclosed for improving the security of computer networks by providing a means operating passively on the network for detecting, reporting and responding to intruders. The system is comprised of a plurality of intruder sensor client computers and associated event correlation engines. Resident in the memory of the client computer and operating in the background is a Tactical Internet Device Protection (TIDP) component consisting of a passive intruder detector and a security Management Information Base (MIB). The passive intruder detector component of the TIDP passively monitors operations performed on the client computer and emits a Simple Network Management Protocol (SNMP) trap to an event correlation engine when it identifies a suspected intruder. The event correlation engine, through the use of a behavior model loaded in its memory, determines whether the user's activities are innocent or those of a perspective intruder.

Abstract: The methods and systems relate to tracking targets, and more particularly to tracking multiple targets within a field of densely distributed sensor nodes using wave processing/analysis methods applied to “target-waves” in an observable physical phenomena. The “target-waves” are target induced perturbations of a physical phenomena that are analogous to a propagating wave where the wave propagation velocities are equal to the target velocities. The term “target” refers to an individual object, or a group of objects that can be treated as an entity, whose position, speed, direction, separation, etc. is of interest to a user. Some examples, not exclusive, are military vehicles (e.g. tanks) along a road, people on sidewalks or in halls, and ships at sea.

Abstract: A system and method for routing telephone calls is based on identifying caller goals, and maximizing the benefit of routing the call to the appropriate call center. The appropriate call center is identified as the call center best equipped to respond to the needs of the caller. The cost or benefit is based on the fastest and least expensive way to answer a query posed by a caller. A probabilistic model of the caller's goals or call topics based on a response to a top-level prompt is used, along with a set of functions associating a utility or benefit with routing those call topics to destinations within the center. Maximum benefit routing allows for the separation of the caller's goals from those of the call center, thereby optimizing use of available resources.

A sensor (150) may connect to the first and second sensor mounting pads to measure the amount of load or displacement.

Abstract: A system and method to provide maximum power over large angular sectors using an array of transducers is disclosed. Array segments of transducers and phase shifters form a beam from each of the array segments, wherein the set of beams overlap to form a large sector coverage beam. The phase of each of the signals fed to the radiating elements is shifted, such that the difference between beam point directions of the beams of two adjacent array segments is substantially equal to one half of the sum of the beamwidths of the beams of the two adjacent array segments. The phase of each of the signals fed to the radiating elements may also be shifted in proportion to the square of the distance between one end of the array of transducers and the position of each of the plurality of radiating elements.
