摘要： Techniques for highly parallel evaluation of XACML policies are described herein. In one embodiment, attributes are extracted from a request for accessing a resource including at least one of a user attribute and an environment attribute. Multiple individual searches are concurrently performed, one for each of the extracted attributes, in a policy store having stored therein rules and policies written in XACML, where the rules and policies are optimally stored using a bit vector algorithm. The individual search results associated with the attributes are then combined to generate a single final result using a predetermined policy combination algorithm. It is then determined whether the client is eligible to access the requested resource of the datacenter based on the single final result, including performing a layer-7 access control process, where the network element operates as an application service gateway to the datacenter. Other methods and apparatuses are also described.

摘要： Techniques for providing extensibility framework for processing network packets are described herein. In one embodiment, in response to a packet received at a network element, the packet is processed using a generic process for performing a first type of operations required by the packet, wherein the first type of operations is common to a type of the packet. An extended process is invoked, via an extensibility application programming interface (API), to perform a custom operation that is not common to the generic process and is not statically known to the generic process, in order to determine whether the packet is eligible to access a resource of at least one of a plurality of application servers of a datacenter, including a layer-7 access control process. The network element operates as an application service gateway for the datacenter. Other methods and apparatuses are also described.

摘要： A system and method that allows an administrator to set a new password at a wireless access point, such as a traditional WAP or a wireless router. The wireless access point creates a message that includes the new password. The message is encrypted using the old password that was previously set for the wireless network. The encrypted message is wirelessly transmitted from the wireless access point to the active client devices (those clients currently accessing the wireless network). The clients decrypt the message using the old password that was previously provided to the clients. The clients retrieve the new password from the message. The clients construct a new message that is encrypted using the new password. The new message is wirelessly transmitted from the clients to the wireless access device and serves as an acknowledgement.

摘要： Described herein are methods and devices for selectively applying fluids (particularly anesthetics) to a target tissue from within a blood vessel while minimizing the amount of fluid applied to non-target tissue. The injection catheters described herein may include an elongate body, a directional injector, and one or more holdfasts for securing the catheter before extending the injector. The methods of selectively applying anesthetic to a target structure generally include the steps of inserting an injection catheter into a body vessel, positioning the injection catheter within the body vessel near the target structure, anchoring the injection catheter before extending a directional injector from the injection catheter, and applying anesthetic from the injection catheter to the target structure.

摘要： A system and method for concurrent security connections is presented. An association table is used that includes a list of active credentials. An active credential includes information such as user id and password information for a given domain. The active credential may also include dynamic data that is retrieved from a user, such as a pseudo-random code or a fingerprint scan. The active credential is sent to a domain, or the managing server of the domain, when domain access is requested. This access request does not involve the user of the client unless dynamic input data is requested.

摘要： An engine valve actuation system includes an engine valve moveable between first and second positions, a valve actuation assembly connected to move the engine valve between the first and second positions, a fluid actuator configured to selectively modify a timing of the engine valve in moving from the second to the first position, a source of fluid, and a pair of passages in the cylinder that allow fluid to flow from the chamber to the fluid source. The fluid actuator includes a cylinder and a piston at least partly defining a chamber. The piston is slidably movable in the cylinder between a first position and a second position, and blocks at least a portion of one of the passages at an intermediate position between the second position and the first position to reduce fluid flow from the chamber when the piston moves from the second position toward the first position.

摘要： An engine valve actuator for an internal combustion engine is provided. The engine valve actuator includes a housing having an opening and a first fluid passageway leading to the opening. An adjustment member is disposed in the housing and includes a protrusion that extends into the opening of the housing. A piston is disposed in the opening of the housing and has a bore adapted to receive the protrusion, a chamber, and a second fluid passageway that connects the bore with the chamber. The piston is adapted to move in a first direction relative to the housing in response to an introduction of pressurized fluid into the first fluid passageway. The piston moves in the first direction until the protrusion substantially withdraws from the bore. A push rod is operatively engaged with the piston such that movement of the piston in the first direction causes a corresponding movement of the push rod to thereby engage and open the engine valve.
