摘要:
Embodiments of the invention include a system for an integrated circuit development. Elements of the development system include hardware and software objects. These objects can be instanced, ordered, parameterized, and connected in a software environment to implement different functions. Once in software, the description defines the topology and the properties of a set of objects and hence the overall function. These objects are hierarchically composed from a set of primitive objects. By using a piece of hardware that can model any primitive object set as pre-established encapsulated hardware objects, the topology and properties define a piece of hardware that can perform the desired, implemented, functions. Using embodiments of the invention, circuit designers can design hardware systems with little or no knowledge of hardware or hardware design, requiring only a high-level software description.

The invention discloses a pre-filled orthopedic cement container in which the cement can also be mixed. The container comprises an outer housing defining the mixing chamber and an inner housing containing the cement prior to mixing. The inner housing is removable, prior to mixing, in such a way that the cement powder remains in the mixing chamber for mixing.

An analysis apparatus for performing biochemical analysis of a sample using nanopores comprises: a sensor device that supports plural nanopores, reservoirs holding material for performing the analysis; a fluidics system; and plural containers for receiving respective samples, all arranged in a cartridge that is removably attachable to an electronics unit arranged to generate drive signals to perform signal processing circuit to generate output data representing the results of the analysis. The fluidics system supplies samples selectively from the containers to the sensor device using a rotary valve.

The present invention allows Internet Protocol television (IPTV) services to be provided to different types of subscriber devices over different types of networks via a multimedia subsystem, such as an IP multimedia subsystem. A given subscriber may have one subscription supporting IPTV services to different types of subscriber devices. Each of the subscriber devices may register with a given IPTV application server, which will interact with the various subscriber devices using a common session control protocol, such as the Session Initiation Protocol (SIP). The IPTV sessions may support delivery of various types of streaming content, such as audio or video content, for broadcast or on-demand services. Different IPTV sessions are used to support broadcast and on-demand services. However, within a given broadcast or on-demand IPTV session, channels may be changed or the streaming media may be controlled within the respective IPTV sessions.

An orifice fitting having a drainage system. In some embodiments, the orifice fitting includes a housing having a chamber therein, a flow path extending through the chamber, an orifice plate moveable between a first position in the flow path and a second position outside of the flow path, and a rotatable shaft extending through the housing into the chamber. The shaft has a flowbore extending between a first fluid inlet in fluid communication with the chamber and a fluid outlet formed adjacent the end of the shaft.

Apparatus and methods for operating a dual chamber orifice fitting. The dual chamber orifice fitting comprises a body having a lower chamber and a top having an upper chamber. An aperture connects the upper chamber to the lower chamber. A closure member is pivotally mounted to the fitting and pivots about a first axis between a first position and a second position. A pivot arm is rotatably mounted to the body and engages the closure member so that rotation of the pivot arm about a second axis pivots said closure member about the first axis between the first and second positions.

A control mechanism comprises an elongate handle 10 having an external thread 12 and a barrel 20 with internally projecting pins 21 threaded over handle 10. Rotation of barrel 20 causes handle 10 to move back and forth along its longitudinal axis to retract and advance a catheter sheath to which handle 10 is coupled, thereby enabling an implant to be deployed by the catheter. Rotation movement of barrel 20 and longitudinal movement of handle 10 can be disassociated to enable speedy retraction or advancement of the catheter sheath.
摘要:
A SIP header reduction protocol operating on a communication network to compress the SIP header fields on SIP control messages used to initiate a SIP communication session. The new protocol is implemented on the mobile use equipment (UE) (301) and P-CSCF proxy SIP server (302). The prior SIGCOMP compression dictionary is used to compress those header field parameters defined by the SIGCOMP dictionary. A new 3G Dictionary is implemented with header field parameters for several wireless specific data elements and parameters necessary to access various wireless technologies and services which are missing from the SIP/SDP based SIGCOMP dictionary. Finally, an Encoding Assistant (EA) (310, 355) function is implemented on the UE and P-CSCF that operates a standard encoding and decoding of SIP message header fields to reduce those SIP header fields that are dynamic over time but are essentially static in terms of most user communication. The EA parameters can be updated periodically, while the 3G and SIGCOMP dictionary are static and not updated.
