An innovative security solution which separates a client into a Protected Context, which is the real files and resources of the client, and an Isolated Context, which is a restricted execution environment which makes use of virtualized resources to execute applications and modify content in the Isolated Context, without allowing explicit access to the resources in the Protected Context. The solution further consolidates user interfaces to allow users to seamlessly work with content in both contexts, and provide a visual indication of which display windows are rendered from content executed in the Isolated Context.

A method, terminal device, network element, system and computer program product for controlling discontinuous reception or transmission at a terminal device of a communication network are disclosed. A regular discontinuous reception or transmission cycle of a regular discontinuous reception or transmission scheme is set by using a first control layer, and in addition thereto a shorter temporary discontinuous reception or transmission cycle of an interim discontinuous reception or transmission scheme can be set by using a second control layer. This arrangement provides long discontinuous reception or transmission cycles for power consumption improvements while at the same time ensuring that the network can easily and flexibly shorten these cycles for increased data throughput, if needed.

A method and apparatus for optimizing a circuit design using a library of cells in which a continuous spectrum of cells are provided. A library containing real and virtual cells is used so that cells can be selected across a wide spectrum of a design parameter, such as drive strength. The cells are provided in discrete steps small enough that the effect of having a continuous spectrum of cells is achieved. After optimization, only the cells finally selected need be actually synthesized, and when these constitute a small percentage of the total number of cells, the impact to library size and final placement and routing is minimized. Thus the ability to optimize across a continuous spectrum is achieved while preserving a cell library based design flow.

A system and method for protection of Web based applications are described. A Web application security system is included within a computer network to monitor traffic received from a wide area network, such as the Internet, and determine if there is a threat to the Web application. The Web application security system monitors web traffic in a non-inline configuration and identifies any anomalous traffic against a profile that identifies acceptable behavior of a user of the application. Any anomalous traffic is analyzed and appropriate protective action is taken to secure the Web application against an attack.

Mobile routers in a tree-based network topology with a single clusterhead in an ad hoc network establish connectivity based on each attached mobile router sending a neighbor advertisement message to an attachment mobile router via a corresponding egress interface. Any neighbor advertisement message received by a mobile router is used to identify specified network prefixes that are reachable via the source of the neighbor advertisement message. Each attached mobile router outputs to its attachment router another neighbor advertisement message that specifies the network prefix used by the mobile router, and the specified network prefixes from its attached mobile routers. The mobile router also identifies peer mobile routers having the same depth, and selectively shares limited routing information with the peer routers, enabling the mobile router to bypass the clusterhead and reach remote prefixes via the peer routers without burdening the tree.

The invention relates to methods for improving the DRX operation of a UE by introducing an additional DRX wake-up cycle, which runs in parallel to the short and/or long DRX cycle. The DRX wake-up cycle defines time intervals after which the UE starts monitoring the PDCCH for a wake-up duration of time; the UE does not perform any other operation during the wake-up duration apart from monitoring the PDCCH. The time intervals of the wake-up cycle between the wake-up durations are preferably shorter than the one of the DRX long cycle, and may have the same or a shorter length than the ones of the DRX short cycle. The wake-up duration may be as long as the on-duration of the DRX short/long cycle, or may be preferably much shorter, such as only one or a few subframes.

Systems and methods are disclosed for providing supplemental power to a battery powered information handling systems. The disclosed systems and methods may be implemented to intelligently control the selected use of supplemental power so as to reduce or substantially prevent an increase in battery usage cycle count by only allowing use of supplemental power above a given minimum supplemental battery charge level threshold. Battery cycle count may be further enhanced by only again allowing recharging of the system battery pack when its charge level drops below the minimum supplemental battery charge level threshold, and then recharging to a maximum recharge battery charge level threshold which also may be selectable by a user and/or provider of the information handling system.

A database structure of a sort defined by an access and query language that defines tables of variables having labels and field characteristics, such as ANSI structured query language (SQL), is modified by determining the structural differences between an existing schema and a new schema, independent of database contents. The differences are processed to generate commands that are then applied to evolve an existing database from the old schema or structure to the new one. This avoids the need to dump and restructure the contents of the old database for reload into an empty new database that has been prepared to meet the new schema.

A nasal air filtration device includes a pair of either planar or concave-convex filters, a support structure incorporating a pair of generally annular bases or sleeves for supporting the filters, and a bridge that couples the bases or sleeves to maintain them in a desired spaced-apart relation and to determine a desired angular relationship. The support structure is insertable into the nasal cavities to position the filters within corresponding nasal cavities. Flexible rims maintain the support structure and the filters in spaced-apart relation to the surrounding nasal wall. The rims conform to surrounding nasal tissue to form seals. The rims can be selectively inclined to facilitate insertion and resist accidental removal. In certain embodiments the device is combined with a filter that covers the mouth to provide an air filtration system.

A system and method for the dynamic distribution of intrusion signatures to aid in protecting a network system from harmful activities. An analysis function includes means for identifying one or more intrusion signatures to be dynamically distributed to an intrusion detection function for monitoring. The analysis function and/or the intrusion detection function may be centralized or distributed. Monitoring may be prioritized, localized, and made operational or non-operational. The intrusion detection function may be embodied in either or both of an appliance and a network forwarding device. The analysis function may distribute the intrusion detection function in addition to the intrusion signatures. In one embodiment of the invention, the system includes an intrusion detection function and a dynamic intrusion signatures function. The intrusion detection function monitors for and reports detected intrusion signatures. The dynamic intrusion signatures function determines whether reported intrusion signatures exist in a library of signatures associated with a particular intrusion detection function. If the reported signature does not exist in the library, the library is updated. Detected intrusion signatures are reported to similarly enabled devices for library analysis and updating, if necessary. The related method includes the steps of monitoring for intrusion signatures or other triggering events, analyzing the events and updating IDS signature libraries as necessary. Optional steps of the method include verifying that reported information has been received and acted upon, and recording of the detection, reporting, and updating information in a central repository. The system and method enable dynamic distribution of IDS signatures enabling improved network IDS coverage while limiting the processing and storage requirements of network devices, particularly forwarding devices such as switches and routers that may include the IDS function. That capability enables broader coverage, faster and better tuned responses to harmful activities.

The ultrasound catheter housing comprises a an inner thin wall polymer tube extruded using an ultrasonically transparent polymer, a thin metalized layer deposited on the outer surface of the inner tube, and an outer thin wall polymer tube, which may be the same or a different ultrasonically transparent material. In another embodiment an ultrasound catheter comprising the ultrasound catheter housing is provided.

A cluster of computer system nodes connected by a storage area network include two classes of nodes. The first class of nodes can act as clients or servers, while the other nodes can only be clients. The client-only nodes require much less functionality and can be more easily supported by different operating systems. To minimize the amount of data transmitted during normal operation, the server responsible for maintaining a cluster configuration database repeatedly multicasts the IP address, its incarnation number and the most recent database generation number. Each node stores this information and when a change is detected, each node can request an update of the data needed by that node. A client-only node uses the IP address of the server to connect to the server, to download the information from the cluster database required by the client-only node and to upload local disk connectivity information.

A method and a system for dynamically detecting and correcting anomalous pixels in the raw data taken from an image sensor array such as a CCD or a CMOS sensor array, thus allowing the use of dumb cameras to capture digital images for subsequent use by an intelligent host—such as being displayed on a computer monitor. This invention uses software algorithms running on an intelligent host processor to dynamically correct the anomalous pixels in the raw data taken from an image sensor array typical of those in a digital still or a video camera. Using the combination of a dumb camera which provides raw data to an intelligent host, which does all the subsequent image processing, the system works by scanning an image frame for pixels that vary more than a specified amount in their brightness value from their neighboring pixels and designating those as defective pixels. The location and frequency of the photosites sending the defective pixels are stored in a statistical database in the computer's memory. The brightness value of a defective pixel is then replaced by a local brightness value obtained from the defective pixel's neighboring pixels. The process includes video subsampling, meaning that the defective pixel detection is carried out and repeated at a pre-specified frame rate to ensure optimum detection and correction at a minimal level of scanning. A statistical database is kept so that truly anomalous pixels can over time be distinguished from false detection of true anomalies in the target image, lighting or other environmentally induced anomalies.

An aggregation procedure for aggregating of a number of session descriptions parameters corresponding to a multitude of channels into one single session description. Each channel is described by a mandatory unique identifier. A corresponding client application processes the SDP describing the channel bundle and uses the found information for allowing a user to switch to a channel associated with a certain identifier. Signaling of a channel switch control unit, which is part of the multi-channel streaming server, receives a multitude of RTP flows and selects one of the flows for forwarding to the client. A switching point determination is a part of the channel switch control unit and determines the next possible point of time for switching to a requested channel. The client application receives time information for the switch point in response to a channel switch request.

The present invention performance enhancement and reliability maintenance system and method pushes a processor to its maximized performance capabilities when performing processing intensive tasks (e.g., 3D graphics, etc). For example, a clock speed and voltage are increased until an unacceptable error rate begins to appear in the processing results and then the clock speed and voltage are backed off to the last setting at which excessive errors did not occur, enabling a processor at its full performance potential. The present invention also includes the ability to throttle back settings which facilitates the maintenance of desired reliability standards. The present invention is readily expandable to provide adjustment for a variety of characteristics in response to task performance requirements. For example, a variable speed fan that is software controlled can be adjusted to alter the temperature of the processor in addition to clock frequency and voltage.
