Abstract: A system and method are disclosed that include a bridge that translates non-coherent transactions, which are received from a non-coherent subsystem, into one or more coherent transactions to be issued to a coherent subsystem. The bridge also buffers data coherently in an internal cache, also known as a proxy cache, based on certain attributes of the non-coherent transaction. The invention may be applied to any cache, which receives read and write transactions that become coherent transactions.

Abstract: Compression of address bits within a cache coherent subsystem of a chip is performed, enabling a cache coherent subsystem to avoid transmitting, storing, and operating upon unnecessary address information. Compression is performed according to any appropriate lossless algorithm, such as discarding of bits or code book lookup. The algorithm may be chosen according to constraints on logic delay and silicon area. An algorithm for minimum area would use a number of bits equal to the rounded up binary logarithm of the sum of all addresses of all memory regions. A configuration tool generates a logic description of the compression algorithm. The algorithm may be chosen automatically by the configuration tool. Decompression may be performed on addresses exiting the coherent subsystem.

Abstract: A retractable syringe, plunger and releasable needle assembly including a retractable needle, a needle seal, a retaining member and an ejector member. The retaining member has a mating surface for mounting to a complementary mating surface of an interior wall of a syringe barrel. The plunger comprises a plunger outer, a plunger rod frangibly connected to a controlling member, a spring and a unitary plunger seal capable of engaging the retractable needle, wherein the plunger rod, plunger outer and the controlling member co-operate to releasably maintain the spring in an initially compressed state. After delivery of fluid contents of the syringe, the plunger forces the ejector member to release the retractable needle from the retaining member. Decompression of the spring at the end of depression of the plunger facilitates retraction of the retractable needle when engaged with the unitary plunger seal.

Abstract: A retractable needle is provided for a syringe comprising a barrel and a plunger that comprises a portion capable of engaging the retractable needle for retraction. The retractable needle comprises a cannula, a needle body having a plunger-engaging member, at least one aperture and an elongate portion which houses the cannula, the cannula comprising an end which is in fluid communication with the at least one aperture, wherein the at least one aperture is located between the plunger-engaging member and the elongate portion. The positioning of the at least one aperture distal to the plunger-engaging member maximizes the efficiency of fluid delivery.

Abstract: Multiple cookies of a client device are used to form an identifier of the client device such that a change in one or even several browser cookies does not defeat proper device recognition. The cookies are included in the identifier such that individual cookies can be parsed for separate comparison with corresponding cookies of known devices. However, to protect privacy of all devices, individual parameters of the constituent cookies are represented with irreversible hashes of the respective parameters. Recognition involves quantification of a degree of correlation between the cookies and corresponding cookies of each of the known devices. To quantify the degree of correlation, the observed stability and uniqueness of each cookie, and each cookie attribute, is considered.

Abstract: A system and method are disclosed for multiple coherent caches supporting agents that use different, incompatible coherence models. Compatibility is implemented by translators that accept coherency requests and snoop responses from an agent and accept snoop requests and coherency responses from a coherence controller. The translators issue corresponding coherency requests and snoop responses to the coherence controller and issue corresponding coherency responses and snoop requests to the agent. Interaction between translators and the coherence controller accord with a generic coherence model, which may be a subset, superset, or partially inclusive of features of any native coherence model. A generic coherence protocol may include binary values for each of characteristics: valid or invalid, owned or non-owned, unique or shared, and clean or dirty.

Abstract: A portable power device including an enclosure, a plurality of power elements housed within the enclosure, and a controller housed within the enclosure and configured to control the power output of the plurality of power elements. The controller is configured to determine if the portable power device is located on an aircraft that is operating in a stationary, taxiing, or flight mode, and if the aircraft is in the stationary, taxiing, or flight mode, to prevent power to be supplied from the plurality of power elements.

Abstract: A system and method for performing coherent cache snoops whereby a single or limited number of sharing coherent agents are snooped for a data access. A directory may store information identifying which coherent agents have a shared copy of a cache line. If more than one might be in a shared state, one is promoted to an owner state within the directory. Accesses to the shared cache line are responded to by a snoop to just one, or a number less than all, of the caching agents sharing the cache line.

Abstract: A cache coherent system includes a directory with more than one snoop filter, each of which stores information in a different set of snoop filter entries. Each snoop filter is associated with a subset of all caching agents within the system. Each snoop filter uses an algorithm chosen for best performance on the caching agents associated with the snoop filter. The number of snoop filter entries in each snoop filter is primarily chosen based on the caching capacity of just the caching agents associated with the snoop filter. The type of information stored in each snoop filter entry of each snoop filter is chosen to meet the desired filtering function of the specific snoop filter.

Abstract: A distributed implementation for cache coherence comprises distinct agent interface units, coherency controllers, and memory interface units. The distinct units are separated logically and physically. Units are interconnected, and communicate with each other, by a transport network. Different organizations of connectivity are possible and chosen based on system performance and physical floorplan design constraints. The cache coherence subsystem is designed using software that exports a description of the system in a hardware description language.

Abstract: A failover procedure for a computer system includes steps for routing traffic from a routing device to a first server, storing in the routing device data representing a fingerprint of the first server, receiving periodically at the routing device a status message from the first server, detecting at the routing device an invalid status message from the first server by absence of the fingerprint in a status message from the first server within a predetermined time period after last receiving a valid status message, and routing the traffic from the routing device to a second server in response to detecting the invalid status message from the first server. A redundant server system implementing the failover procedure may include servers each capable of generating its fingerprint by reading current system configuration data.

Abstract: System and method for auditing for usage of licensed software in which a client executing the software generates and transmits a license key and a covert key to a server via network connection. The license key is transmitted to the server upon activation of the licensed software at the client. The covert key is generated based on at least a portion of the software code activated at the client and is transmitted to the server at random or at predetermined time intervals after transmission of the licensed key so as to avoid detection by a user. The license and covert keys are each associated with a device fingerprint that uniquely identifies the device transmitting each one of the respective keys. Unauthorized software usage at a client is determined at least when a covert key does not correspond to a device fingerprint having an associated license key.
