Abstract: A system for establishing a client/server type relationship in a hybrid peer to peer network connects a first peer (20a) to a second peer (20d) implementing a predetermined function (F) in that peer to peer network. To this end, the first peer (20a) has a superpeer (10a) capable of establishing a list (LF) of the active peers (20d, 20e) implementing the function (F) in the service of the peers of the network and of sending that list (LF) to its peer (20a). The first peer (20a) can then establish a client/server type relationship with a second peer (20d) selected in that list (LF).

Abstract: A caching proxy server for a hybrid peer-to-peer (P2P) photosharing system is provided. In general, the proxy server includes cache storing a number of previously requested digital images, a metadata database storing metadata including a number of keywords associated with each of the digital images stored in the cache, and a metadata usage table storing a number of “hits” for each of the keywords. When the used storage space in the cache reaches a predetermined limit, the proxy server examines the metadata usage table to determine a popularity of each of the keywords and removes digital images tagged with one or more of the least popular keywords until the used storage space in the cache decreases to a desirable level. As such, the proxy server ensures that digital images tagged with the most popular keywords remain in the proxy cache and are therefore available for subsequent requests.

Abstract: A band-limiting filter of the invention exhibits a trimodal filter characteristic, and includes, for example, band-limiting transmittance filter characteristic portions Rb, Gb, and Bb for wavelength regions of red, green, and blue, respectively. More specifically, the band-limiting transmittance filter characteristic portions Rb, Gb, and Bb, for example, have bandpass characteristics in which the respective center wavelengths are 630 nm (full width at half maximum ?1=30 to 90 nm), 540 nm (full width at half maximum ?2=20 to 60 nm), and 440 nm (full width at half maximum ?3=50 to 80 nm). This makes it possible to obtain an image of a predetermined color tone by restraining an influence of spectral sensitivity characteristic of an image pickup device when the band-limiting filter is applied to a synchronous type endoscope for performing color image pickup to perform observation under normal illumination light.

Abstract: A method is provided for detecting a threat in a distributed multi-camera surveillance system. The method includes: monitoring movement of an object in a field of view of a first camera using software installed at the first camera; detecting a suspicious object at the first camera when movement of the object does not conform with a motion flow model residing at the first camera; sending a tracking request from the first camera to a second camera upon detecting the suspicious object at the first camera; monitoring movement of the object in a field of view of the second camera using software installed at the second camera; assigning threat scores at the second camera when the movement of the object does not conform with a motion flow model residing at the second camera; and generating an alarm based in part on the threat scores detected at the first camera and the second camera.

Abstract: Aspects of the present invention include distributing new resources closer to end-users which are making increased demands by spinning-up additional virtualized instances (as part of a cloud provisioning) within servers that are physically near to the network equipment (i.e., web servers, switches, routers, load balancers) that are receiving the requests.

Abstract: A system and method are provided for accessing and managing information, or metadata, describing content residing on a number of agent devices. In general, the system includes a central node and a number of agent devices communicatively coupled by a network. In operation, the central node communicates with the agent devices to obtain content information describing content stored at the agent devices and optionally the locations of the agent devices from the agent devices. The content information and optionally the locations of the agent devices are stored in a database associated with the central node. Thereafter, the central node enables requesting nodes such as the agent devices to access the database. In addition or alternatively, the central node may provide automatic alerts to the agent devices when other agent devices matching specified criteria are available.

Abstract: A method of controlling distribution of content in a message sent by a message sender comprises receiving an indication from the message sender that the message is to be protected, identifying content in the message to be protected, adding the identified content to a database of protected content, and determining whether subsequently received content in a subsequently received message is associated with the identified content. A system for controlling distribution of content in a message sent by a message sender comprises a processor configured to receive an indication from the message sender that the message is to be protected, identify content in the message to be protected, add the identified content to a database of protected content, and determine whether subsequently received content in a subsequently received message is associated with the identified content.

Abstract: A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Abstract: The present invention is directed to enable a monitoring apparatus to reliably obtain information of an event which occurs in an apparatus to be monitored in a monitoring system employing a connectionless communication method. An apparatus to be monitored comprises: a first transmitting unit for transmitting first information as event information related to an event in the apparatus to be monitored to a monitoring apparatus by a connectionless communication method; and a second transmitting unit for transmitting second information as the event information to the monitoring apparatus by a communication method different from the connectionless communication method. The monitoring apparatus comprises: a first receiving unit for receiving the first information transmitted from the first transmitting unit; and a second receiving unit for receiving the second information transmitted from the second transmitting unit.

Abstract: A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a set of message classification rules that have been prepared beforehand by a system administrator or customer. The system analyzes the message classification rules to determine what part(s) of the message are necessary to classify a message according to the message classification rules. This allows the system to consider only the relevant parts of the message and ignore the rest of the message. The system extracts the portion of the message necessary for classifying the message and classifies the message using the values of the extracted information and the message classification rules. A unique sequence of operations is implied by the message classification and those operations must then be applied to the message.

A cluster comprising a number of network elements and disk elements exports one or more logical units to iSCSI initiators. Each of the network elements is operatively interconnected with a replicated database which is utilized to share initiator data structures and lun mapping information. An iSCSI initiator may communicate with any of the network elements to access any of the logical units exported by the cluster.

Abstract: A method of placing prefix hijacking detection modules in a communications network includes selecting a set of candidate locations. For each candidate location, a detection coverage ratio with respect to a target Autonomous System is calculated. Based on the relative size of the coverage ratios, proposed locations for the prefix hijacking detection modules are determined.

Abstract: A video based method to detect volatile organic compounds (VOC) leaking out of components used in chemical processes in petrochemical refineries. Leaking VOC plume from a damaged component causes edges present in image frames to loose their sharpness, leading to a decrease in the high frequency content of the image. Analysis of image sequence frequency data from visible and infrared cameras enable detection of VOC plumes in real-time. Analysis techniques using adaptive background subtraction, sub-band analysis, threshold adaptation, and Markov modeling are described.

Abstract: A system and method of locating a lost wireless communication device is provided. A remote server is contacted to indicate that the wireless communication device is lost. A lost device policy setting is then activated in a database coupled to the remote server, the lost device policy setting indicating that the wireless communication device is lost. In response to activation of the lost device policy setting, a remote location command is then transmitted from the remote server to the wireless communication device via a wireless network. The remote location command is subsequently received at the lost wireless communication device, which processes the remote location command such that a user of the wireless communication device can locate the device.

Abstract: Systems and methods are provided that disclose a network service for modularly constructing a software defined radio (“SDR”). A server system provides an SDR kernel (i.e., a potentially platform-neutral definition of digital signal processing functionality and control operations necessary to implement the core portion of a software defined radio implementing a particular radio standard) to a client system. The client system may select a desired SDR kernel through a variety of means disclosed herein. While some SDR kernels may be provided for free and unrestricted use, others may be purchased or subscribed to and additionally restricted by digital rights management (“DRM”) policies. Based upon the agreed upon payment terms and any other restrictions, a customized set of DRM policies may be applied by the server system to the SDR kernel before sending it to a client system. Additionally, the server system may provide a description of governmental regulations applicable to a given locality.

Abstract: There is provided a method for mediating the flow of messages in a computer network having a mediation architecture that includes a plurality of logical nodes in a cubic mediation arrangement.

Abstract: Methods and systems for simulating an online session between the client and a remote server when the client is offline including simulating a web services API to access information when the client is offline. The client includes a local interface that can communicate with the remote server. During an online session, the data and the functional logic that is invoked to manipulate the data reside on the remote server. As such, the user transmits instructions to view, create, update, delete, or otherwise modify portions of data through the local interface and subsequently through the underlying network. These instructions are ultimately received at the remote server, which then invokes the proper functional logic to perform the instructions in order to manipulate the data. An API is provided that is substantially identical to the web services API that is typically accessed over the internet, but which simulates online functionality when offline.
