Abstract: A simplified methodology for accomplishing traffic management in a packet based network is achieved by allowing allocation of bandwidth based on a count of the number of endpoint connections associated with a specific service for a corresponding network device. A network device (e.g., IP router) can be configured to count the number of TCP/IP and UDP/IP connections and bandwidth usage per interface. The counting can be done by identifying the IP Addresses, Type of Service (TOS), and TCP/UDP and/or UDP/IP socket number range in the IP Header of a packet and then querying a specific communication type. When reaching the maximum allowed connections or bandwidth for a specific service, the network device (e.g., IP router) stops forwarding any new calls by means of dropping packets of new calls and informing the given endpoints to disconnect the new calls.

Abstract: The present invention provides a method and system for sending a server-specified message from an application server to Customer Premises Equipment (CPE) without setting up a call path between the application server and the CPE. The application server is coupled with a switch, which is in turn coupled with the CPE. The application server sends a request to the switch. The switch sends, based upon the request, a predetermined server-specified message to the CPE without setting up a call path between the application server and the CPE. The CPE is not rung and the predetermined message is not affected by the features of the line associated with the CPE.

Abstract: A method for recognizing a table structure from delineated table region in an electronic document using hierarchical clustering of data strings. The cluster groupings are segregated effectively using the distances from a positional vector associated with words and groups of words rather than a minimum number of blank spaces between words. Once a data tree of the hierarchical clusterings is constructed, the tree is scanned downward from the root to find appropriate column boundaries using a columnization algorithm. Then using successive heuristic algorithms, determine column and row headers and row boundaries.

Abstract: Packets are scheduled for transmission over a communication link in a network, using a Largest Weighted Delay First (LWDF) scheduling policy. A delay measure Wi, i=1, 2, . . . N, is computed for each of N packets, each associated with a corresponding one of N data flows and located in a head position in a corresponding one of N data flow queues. The computed delay measures are then weighted using a set of positive weights ?1, ?2, . . . , ?N. The packet having the largest weighted delay Wi/?i associated therewith is then selected for transmission. In an embodiment configured to meet a quality of service (QoS) requirement specified in terms of a deadline Ti and an allowed deadline violation probability ?i, e.g., a requirement specified by P(Wi>Ti)??i, the weights ?i in the set of positive weights ?1, ?2, . . . , ?N may be given by ?i=?Ti/log ?i. The invention can also be used to meet other types of QoS requirements, including, e.g., requirements based on packet loss probabilities.

Abstract: A multiple band antenna (and an array of such antennas) includes a first radiating element that radiates at a first band, at least one second radiating element that radiates at a second band, and a frame to hold the radiating elements. The frame disposes the first and second radiating elements in different planes so that cross-band interference is substantially avoided. Alternatively, a multiple band array antenna includes a first array of radiating elements in a first plane and a second array of radiating elements in a second plane. The first plane overlays the second plane. As a result, individual radiating elements in the first array are substantially interspersed with individual radiating elements in the second array. But the first array and the second array are arranged so that individual radiating elements in the first array substantially do not overlap individual radiating elements in the second array.

The call is initiated by an Open Service Architecture (OSA) application, which causes a message to be produced which indicates to the network that the mobile station is now available to make a ring back call connection. The network setting up the call connection in response to the message.

Abstract: A method of automatically queuing calls for later transmission in connection-oriented networks instead of blocking them when network resources are unavailable at the time the request is received, as currently done. A simple call queuing method holds up call setup messages at each switch along an end-to-end path of a network until resources become available. This simple, known queuing method suffers from poor network utilization and long call queuing delays. However, if calls that can be queued have known holding times, a call scheduling method that results in reduced call queuing delays and improved network utilization according to the present invention can be realized.

Abstract: A communication device is described that includes a POTS interface system, a processing system, a conversion system, a voice interface system, and a digital interface system. When in operation, the POTS interface system receives analog voice signals for a call. The POTS interface system converts the analog voice signals from analog to digital to generate digital voice signals. The processing system performs an application on the digital voice signals to provide a presentation format of the digital voice signals of the call to a user. The conversion system then converts the digital voice signals into analog voice signals and a voice interface system transmits audible signals to the user. The digital interface system receives digital data signals from a data service provider and the processing system performs an application on the digital data signals to provide additional data to the user.

Abstract: A biological/chemical detector is disclosed that is capable of manipulating liquids, such as reagent droplets, without relying on microchannels. In a first embodiment, fluid flow is passed through the detector, thus causing particles wholly or partially containing an illustrative chemical compound or biological species to be collected on the tips of nanostructures in the detector. A droplet of liquid is moved across the tips of the nanostructures, thus absorbing the particles into the liquid. The droplet is caused to penetrate the nanostructures in a desired location, thus causing the chemical compound or biological species in said liquid droplet to come into contact with, for example, a reagent. In another embodiment, a fluid flow is passed through the nanostructured surfaces of the detector such that the chemical compound and/or biological species are deposited between the nanoposts of a desired pixel.

Abstract: Techniques and systems for control of optical switching arrays are described. A switch array controller according to an aspect of the present invention operates so as to achieve reduced power consumption and maintain crosstalk within acceptable limits. Various rules are applied in order to insure that the desired criteria are met. In order to reduce transient effects, switching from one output to another is accomplished in a sequence chosen to maximize the number of transitions occurring in those portions of the array not carrying a signal, and to minimize the number of transitions that occur in portions of the array carrying the signal. Transitions are made in the portion of the array to which the signal will be directed, then a switch is transitioned between the old and new signal paths, and finally further transitions are made in the portion of the array within which the signal was previously directed.

The modulator modulates the carrier signal with a second stream of symbols produced by the modulator. Each symbol of the second stream has a value that corresponds to a sum of the present control symbol and the last K first symbols of the first stream. The integer K is greater than one.

Abstract: A method for calculating an estimate of the clock skew between a sender's clock and a receiver's clock in a packet-based communications network. An adaptive algorithm is employed in which a recursive least squares approach is used to calculate an estimate of the clock skew based on the transmission of a given (i e., the “current”) packet, which estimate is further based on a previous estimate thereof (“a first approximation” thereof). This illustrative process then iterates with each new packet, producing increasingly accurate estimates of the clock skew.
