| 20090037505 | INTERPOLATING CUBIC SPLINE FILTER AND METHOD - A filter for high speed digital signal processing. In one embodiment the filter includes a linear, phase-B, interpolating cubic spline filter having a pre-filter section and an interpolating post-filter section. The pre-filter section may be formed to implement any one of a 1-4-1 cubic spline function, a 2-5-2 cubic spline function or a 1-2-1 cubic spline function. The post-filter may be formed using a plurality of running average filters arranged in a cascade (i.e., serial) fashion. The filter can be constructed using significantly fewer independent component parts for a given level of pass band and stop band performance criteria, as compared with a conventional finite impulse response (FIR) filter. The filter is thus ideally suited for implementation with very large scale integration (VLSI) technology, and in a wide variety of electronic devices where high speed digital filtering is required. | 02-05-2009 |
| 20090196170 | QUALITY OF SERVICE, POLICY ENHANCED HIERARCHICAL DISRUPTION TOLERANT NETWORKING SYSTEM AND METHOD - According to an embodiment, a method includes a Delay Tolerant Network (DTN) software overlay residing in a first plane of a node of the network is used to define hierarchical forwarding behavior for data being generated in the first plane. In a second plane of the network, local buffering and data retransmission is performed in response to at least one intermittent network outage. Communication between the first and second planes is performed to manage the transmission of data between the first and second planes as needed in the event of at network outage that is longer in duration than the at least one intermittent network outage, to thus prevent the loss of data. | 08-06-2009 |
| 20090212914 | DATA MANAGEMENT FOR INTERMITTENTLY CONNECTED SENSORS - A computer implemented method, apparatus, and computer usable program code for managing data on an intermittently connected sensor. A data management system manages the data on radio frequency identification tags. The data management system comprises a radio frequency identification tag capable of storing the data, program code stored on the radio frequency identification tag, and a reader data processing system. The reader data processing system is capable of receiving the data and the program code from the radio frequency identification tag in a radio frequency signal and capable of executing the program code to read the data. | 08-27-2009 |
| 20090274045 | QOS PROVISIONING IN A NETWORK HAVING DYNAMIC LINK STATES - A network node for a network having dynamic link states includes a processing unit and computer-readable memory for causing the processing unit to monitor a link state of the network; perform QoS provisioning and make appropriate updates to the QoS provisioning based on changes in the link state and QoS provisioning demands of QoS-aware applications; and provide notification to the QoS-aware applications to allow those applications to dynamically adapt to the link state changes. | 11-05-2009 |
| 20090296599 | SYSTEM AND METHOD FOR PROVIDING INTEGRATED SERVICES ACROSS CRYPTOGRAPHIC BOUNDARIES IN A NETWORK - A method for providing network integrated services based ReSerVation Protocol across a cryptographic network boundary includes assigning one or more DiffServ forwarding classifications to correspond to IntServ requests for QoS provisioning. A daemon in the QoS Service Provider module signals the QoS upon detecting data packets indicating a DiffServ forwarding class assigned to IntServ QoS requests. In response to the notification, the QoS Services Provider module initiates an RSVP-based request for network resources, and establishes a network path in response to acceptance of the RSVP path request. The data flow comprised of encrypted data is then transmitted over the reserved path. Multiple simultaneous aggregated flows may be provisioned. Paths may be reconfigured and resized by the QoS services provider module in response to an overlimit data flow, subject to network resource availability. An ECN bit is returnable from the destination application to signal a problem with the data transmission. | 12-03-2009 |
| 20100052911 | SYSTEMS, METHODS, AND APPARATUS FOR RFID TAG DETECTION - A system for tracking objects that include radio frequency identification (RFID) tags associated therewith. The system including a structure substantially defining an enclosure, a reflective interior of the enclosure configured for the reflection of radio signals, at least one conveyor belt that transports the objects through the structure, at least one RFID reader panel inside the structure, wherein the at least one RFID reader panel transmits a radio signal into the interior of the structure such that the radio signal will reflect off of the interior of the structure to increase a probability that the RFID tags associated with the objects that enter the structure are read, and an operator terminal that receives and stores information regarding read RFID tags from the at least one reader panel. | 03-04-2010 |
| 20100091650 | SYSTEM AND METHOD FOR CONVEYING PRIORITY ASSOCIATED WITH A COMMUNICATION AMONG A PLURALITY OF NETWORKS - A system for conveying priority associated with a communication conveyed among networks includes: (a) a first network originating the communication in packets; each respective packet including two segments; a first segment containing a portion of the communication in information payload bits in a first encoding scheme; a second segment containing overhead information relating to the packet in overhead bits in a second encoding scheme; a number of the overhead bits being configured to indicate the priority; and (b) a second network cooperating with the first network to alter encoding of the first segment of a selected packet-set to express the information payload bits in a third encoding scheme that is unreadable in the second network; the second network employing the priority-indicating bits to ascertain priority for handling the communication by the second network; the second network preempting lower priority resources to reserve resources for higher priority packet-sets. | 04-15-2010 |
| 20100254395 | METHODS AND APPARATUS FOR ROUTING DATA TO NODES - A method is described for routing data from a first node to a second node via a gateway. The second node is detected at the gateway, which determines a local identifier of the second node. A name and a global address are associated with the second node. The name and the global address are published to a name service, such that the first node can retrieve the global address based on the name. The gateway receives data from the first node that is addressed to the global address and transmits the data to the second node using the local identifier. The gateway includes software implementing a service-oriented architecture (SOA). Any number of additional services may be added to process messages passing through the gateway. | 10-07-2010 |
| 20110013539 | SYSTEM AND METHOD FOR MANAGING INTERNETWORK COMMUNICATIONS AMONG A PLURALITY OF NETWORKS - A system for managing internetwork communications among a plurality of networks includes: (a) a plurality of edge network nodes; each respective edge network node being coupled to manage internetwork communications between a respective own network and other networks of the plurality of networks than the respective own network; and (b) at least one gateway-capable edge network node communicatingly coupled with each respective network node. Each respective edge network node includes a native communication network management unit for managing communications by the respective edge network node using a native communication protocol.
