Abstract: An ophthalmic irrigator-aspirator has a handpiece with aspiration and irrigation openings through its distal end. A tip component connects to the handpiece and has an aspiration cannula. A flexible sleeve has an annular hub for watertight connection to the handpiece or a base portion of the tip. The sleeve has an intermediate portion that forms a channel for an irrigation fluid along the exterior of the cannula to an irrigation port in the sleeve. The distal end portion of the sleeve is sized for a watertight connection over the distal portion of the cannula. Such distal end portion of the sleeve has an aspiration port in communication with the cannula aspiration port. The sleeve proximate, intermediate, and distal portions are integral with each other and are formed of a resilient material that allows the sleeve to be tightly fitted on the handpiece or tip base portion and the cannula.

Abstract: A network controller device, systems, and methods thereof are described herein for enabling a mechanism of assigning network policies to one or more users based on their respective client reputation (CR) scores. CR scores indicate a measure of the level and kind of network activity that an internal resource does with external resources. Based on the evaluation of the CR score for a given user, system of the present invention can be configured to implement an appropriate policy on the user that controls the manner in which the user interacts within and outside the network. Proposed system includes multiple virtual local area networks (VLANs), wherein each VLAN is configured with a defined policy such that once the CR score for a given user has been evaluated, the user can be put on an appropriate VLAN based on the evaluation and the intended policy that the system wants the user to follow.

Abstract: A method for performing policy-based configuration of Internet Protocol Security (IPSec) for a Virtual Private Network (VPN) is provided. According to one embodiment, a policy page through which a policy, including multiple VPN settings for establishing a VPN connection, may be viewed and configured is displayed via a user interface of a source network device. The VPN settings include a type of IPSec tunnel to be established between the source network device and a peer network device. A selection regarding the type of IPSec tunnel to be used for the VPN connection is received via the user interface. The source network device requests the VPN connection be established between the source network device and the peer network device in accordance with the policy by sending a notification request to the peer network device. The notification requests includes parameter values associated with the VPN settings.

Abstract: A method for performing policy-based configuration of Internet Protocol Security (IPSec) for a Virtual Private Network (VPN) is provided. According to one embodiment, a browser-based interface of a network device displays a policy page through which multiple settings may be configured for a VPN connection. The settings include a type of IPSec tunnel to be established between the network device and a peer. One or more parameter values corresponding to one or more of the settings are received and responsive thereto a policy file is created or modified corresponding to the VPN connection. The policy file has contained therein multiple parameter values corresponding to the settings. Establishment of the VPN connection between the network device and the peer is requested based on the parameter values contained within the policy file by sending a notification request, including the policy file, from the network device to the peer.

Abstract: The described implementations relate to updating views in a database system. One implementation can identify an active view that retrieves records from a database and determine one or more physical tables in the database that are referenced by the active view. The implementation can track one or more columns in the physical tables that are used by the active view and identify a change to the physical tables in a transaction log of the database. If the change does not affect the one or more columns, the change can be treated as an ignorable change for the active view.

Abstract: A memory address space for each of a plurality of physical memories in a microprocessor-based system is allocated prior to knowing the desired logical size of at least one of the physical memories. At least two of the allocated memory address spaces overlap at least a portion of each other. After the system is fabricated, a pointer value set that corresponds to an address boundary between at least two physical memories of the fabricated system is set during boot time and/or during run time when the size of the physical memories are known. The technique provides a faster time-to-market for microprocessor-based systems by allowing, for example, Application Specific Integrated Circuits (ASICs) comprising microprocessor systems on-chip be manufactured prior to the final firmware and software being fully developed. Additionally, the subject matter disclosed herein permits changes in memory-space allocation for finalized ASIC designs.

Abstract: A tissue removal device may comprise a handle portion and a tissue removal mechanism coupled to the handle portion. The tissue removal mechanism may include a tubular member having a lumen therethrough and an elongate member rotatably and slidably disposed within the lumen of the tubular member. A proximal end of the elongate member may be coupled to a drive source to impart rotational movement thereof. A distal end of the elongate member may include an impeller for cutting tissue. The elongate member may be configured to exit the distal end of the lumen of the first tubular member, such that the distal end of the second tubular member is distal to the distal end of the first tubular member. The impeller may include a blunt distal end to minimize undesirable tissue damage when the distal end of the elongate member is distal to the distal end of the tubular member.
