An memory module including parallel data compression and decompression engines for improved performance. The memory module includes MemoryF/X Technology. To improve latency and reduce performance degradations normally associated with compression and decompression techniques, the MemoryF/X Technology encompasses multiple novel techniques such as: 1) parallel lossless compression/decompression; 2) selectable compression modes such as lossless, lossy or no compression; 3) priority compression mode; 4) data cache techniques; 5) variable compression block sizes; 6) compression reordering; and 7) unique address translation, attribute, and address caches. The parallel compression and decompression algorithm allows high-speed parallel compression and high-speed parallel decompression operation. The memory module-integrated data compression and decompression capabilities remove system bottlenecks and increase performance. This allows lower cost systems due to smaller data storage, reduced bandwidth requirements, reduced power and noise.

A system and method for searching documents in a data source and more particularly, to a system and method for analyzing and clustering of documents for a search engine. The system and method includes analyzing and processing documents to secure the infrastructure and standards for optimal document processing. By incorporating Computational Intelligence (CI) and statistical methods, the document information is analyzed and clustered using novel techniques for knowledge extraction. A comprehensive dictionary is built based on the keywords identified by the these techniques from the entire text of the document. The text is parsed for keywords or the number of its occurrences and the context in which the word appears in the documents. The whole document is identified by the knowledge that is represented in its contents. Based on such knowledge extracted from all the documents, the documents are clustered into meaningful groups in a catalog tree. The results of document analysis and clustering information are stored in a database.

A limitation in the physical resolution of an image sensor offers a motivation to improve the resolution of an image. Super-resolution is mainly applied to gray scale images, and it has not been thoroughly investigated yet that a high resolution color image is reconstructed from an image sensor having a color filter array. An object of the invention is to directly reconstruct a high resolution color image from color mosaic obtained by an image sensor having a color filter array. A high resolution color image reconstruction method according to the invention is based on novel technique principles of color image reconstruction that an increase in resolution and demosaicing are performed at the same time. The verification and effective implement of the invention are also described.

The present invention provides a novel technique designed to provide a front-end graphical user interface for voice interaction, displaying a list of voice commands that can be used within a control scope of a medical system and that change depending on where the user is in the system. The user is presented with a quick reference guide to available commands without being overwhelmed. “Contextual voice cues” (CVC) provide a non-intrusive dynamic list of available commands to the user which automatically pop-up and change depending on the screen or mode the user is in. An indicator, such as a feedback light, may show whether a voice command is accepted. The technique may be utilized with medical information and diagnostic systems such as picture archival communication systems (PACS), ultrasound modalities, and so forth. Implementation of the technique should increase clinician adoption rates of voice recognition control and thus advance improvements in clinician workflow.

Novel techniques for hearing enhancement based on a pair of glasses are disclosed. In one embodiment, the glasses include a first lens holder, a second lens holder, a bridge element, a first temple, a second temple, a first speaker, a second speaker, a microphone and at least one electrical component that performs a hearing enhanced function to enhance audio signals from the microphone to be sent to the speakers for the user to hear. At least one electrical component in the glasses is for generating other audio signals by the speakers, with the other audio signals originating from signals other than audio signals captured by the microphone. In another embodiment, some of the electrical components are in a portable device, wired or wirelessly, coupled to the glasses. In yet another embodiment, the glasses function as a headset, with other electrical components in the portable device. In such embodiment, since the glasses can provide a number of different hearing functions, a third party may not be able to tell whether the user is wearing the glasses to have his hearing enhanced, or for hearing other audio signals.

A system and method reclaims unused storage space from a data container, such as a logical unit number (LUN) of a storage system. In particular, a novel technique is provided that allows a storage system to reclaim storage space not used by a client file system for which the storage system maintains storage, without requiring assistance from the client file system to determine storage usage. In other words, storage system may independently reclaim storage space not used by the client file system, without that file system's intervention.

A transparent conductive film wherein carbon nanotubes are discursively embedded in the surface portion of a resin film is produced by (A) dispersing carbon nanotubes on a substrate surface, (B) forming a transparent resin film over the substrate on which the carbon nanotubes are dispersed, and then (C) separating the thus-formed resin film. This is a novel technique for realizing a highly transparent conductive film which is flexible and highly conductive even when amount of carbon nanotubes used therefor is small.

A technique efficiently load balances traffic engineering (TE) label switched paths (LSPs) from a head-end node to a tail-end node of a computer network. The novel load balancing technique identifies (e.g., at the head-end node or a path computation element, PCE) a set of paths with equal costs from the head-end node to the tail-end node, where each path of the set is composed of one or more associated links. “Link values” such as, e.g., the number of unconstrained TE-LSPs on the link, the amount of available bandwidth on the link, or the percent of total available bandwidth already in use on the link, are applied to each link of each path. The most restrictive link values (link availability) of each path of the set, such as, e.g., the link with the lowest amount of available bandwidth, etc., are then compared. Upon comparing the link availability, the novel technique load balances established and/or new TE-LSPs from the head-end node to the tail-end node over the set of paths accordingly.

A technique dynamically protects against failure of a head-end node of one or more primary Traffic Engineering Label Switched Paths (TE-LSPs) in a computer network. According to the novel technique, a neighboring upstream node (“protecting node”) of the head-end node learns of the primary TE-LSPs (and their respective state control blocks) extending from the head-end node to one or more address prefixes. The protecting node establishes a repair TE-LSP for each of the primary TE-LSPs to a corresponding downstream neighboring node of the head-end node (a “next-next-hop”). In response to detecting a failure of the head-end node, the protecting node locally reroutes traffic destined for the address prefixes to an appropriate repair TE-LSP. Due to the failure of the head-end node, the protecting node then refreshes the states of the primary TE-LSPs using replicated state control blocks accordingly, until the repair TE-LSPs are no longer needed.

A technique efficiently routes Internet Protocol (IP) traffic on paths between customer edge devices (CEs) across a provider network (“CE-CE paths”) in a computer network. According to the novel technique, a path computation element (PCE), e.g., a provider edge device (PE), may learn dynamic link attribute information of remote links from the provider network to one or more remote CEs (e.g., “PE-CE links” or “CE-PE links”). A multi-homed requesting CE requests from the PCE a set of CE-CE path metrics (e.g., costs) to one or more remote destination address prefixes, e.g., via each multihomed CE-PE link from the requesting CE. In response to the request, the PCE computes the set of available CE-CE paths and current metrics to the remote destination address prefixes and returns the corresponding CE-CE path metrics to the requesting CE. The requesting CE modifies its IP forwarding entries accordingly in order to perform IP traffic routing corresponding to the CE-CE path metrics (e.g., asymmetrical load balancing) across its multi-homed CE-PE links.

A technique dynamically determines whether to reestablish a Fast Rerouted primary tunnel based on path quality feedback of a utilized backup tunnel in a computer network. According to the novel technique, a head-end node establishes a primary tunnel to a destination, and a point of local repair (PLR) node along the primary tunnel establishes a backup tunnel around one or more protected network elements of the primary tunnel, e.g., for Fast Reroute protection. Once one of the protected network elements fail, the PLR node “Fast Reroutes,” i.e., diverts, the traffic received on the primary tunnel onto the backup tunnel, and sends notification of backup tunnel path quality (e.g., with one or more metrics) to the head-end node. The head-end node then analyzes the path quality metrics of the backup tunnel to determine whether to utilize the backup tunnel or reestablish a new primary tunnel.

A technique protects against failure of a network element using Multi-Topology Repair Routing (MTRR) in a computer network. According to the novel technique, a protecting node (e.g., a router) maintains Multi-Topology Routing (MTR) databases for a first topology and at least a second topology. The protecting node determines whether any acceptable repair paths are available in the first topology for a protected network element (e.g., node, link, etc.) of the first topology. If not, the protecting node may establish a repair path (e.g., for Fast ReRoute, FRR) in the second topology for the protected network element.

The present invention includes novel techniques, apparatus, and systems for optical WDM communications. Various wavelocker apparatus and methods are disclosed that measure the frequency offsets between signal lasers and reference lasers. The measured offsets are used to adjust the signal laser frequencies to meet their target frequencies. The absolute accuracy of the reference laser frequency is improved by measuring the absorption of the reference laser by a gas cell with known fixed absorption lines versus the reference laser frequency. Apparatus and methods are disclosed to cover scenarios in which the reference laser polarization is aligned with the signal lasers, as well as those in which the reference laser polarization is not aligned with the signal lasers. The wavelocker apparatus may or may not be located at the same network site as the signal lasers.

A system and method for processing machine learning techniques (such as neural networks) and other non-graphics applications using a graphics processing unit (GPU) to accelerate and optimize the processing. The system and method transfers an architecture that can be used for a wide variety of machine learning techniques from the CPU to the GPU. The transfer of processing to the GPU is accomplished using several novel techniques that overcome the limitations and work well within the framework of the GPU architecture. With these limitations overcome, machine learning techniques are particularly well suited for processing on the GPU because the GPU is typically much more powerful than the typical CPU. Moreover, similar to graphics processing, processing of machine learning techniques involves problems with solving non-trivial solutions and large amounts of data.

A technique dynamically responds to non-network events at a network device in a computer network. According to the novel technique, one or more sensors automatically detect (sense) one or more non-network events, and notifications of the non-network events are then transmitted over the network. One or more network devices (e.g., data centers, servers, routers, etc.) detect the notifications of the network events, and dynamically respond to the non-network events based on one or more associated policies. For example, one or more network-based policies may be defined that modify one or more network configuration parameters in response to the non-network events. Alternatively or in addition, one or more physical-based policies may be defined that instruct one or more network-attached physical control devices to modify one or more physical parameters.

A technique efficiently and dynamically maintains bidirectional forwarding detection (BFD) on a bundle of links in a computer network. According to the novel technique, one or more “standby” BFD sessions may be established on one or more corresponding line cards (LCs), the LCs having one or more links of the bundle (bundle links). Once established, one of the standby BFD sessions may be selected as an “active” BFD session based on activity of one of the bundle links of the corresponding LC. Also, BFD messages may be transmitted from one of the bundle links of the active BFD session, e.g., the link receiving BFD messages. In response to inactivity of the transmitting link (e.g., failure, removal, etc.), the active BFD session may switch to another available active bundle link, and if no other active bundle links are available to the active BFD session, one of the standby BFD sessions is selected as the new active BFD session. In the event no other standby BFD sessions exist, the link bundle is determined to have failed.

Systems, methods, and processes are provided for locating pupils in a portrait image for applications such as facial recognition, facial authentication, and manufacture of identification documents. One proposed method comprises three steps; skin detection, eye detection, and pupil detection. In the first step, the skin detection employs a plurality of Gaussian skin models. In the second step, coarse eye locations are found by using the amount of deviation in the R (red) channel with an image that has been cropped by skin detection. A small block centered at an obtained coarse location is then further processed in pupil detection. The step of pupil detection involves determining a Pupil Index that measures the characteristics of a pupil. Experiments tested on highly jpeg compressed images show that the algorithm of this embodiment successfully locates pupil images. It is believed that this novel technique for locating pupils in images can improve the accuracy of face recognition and/or face authentication.
