A system for initiating and maintaining a real time audio or video media session between two clients, at least one of which has a private network IP address and is supported by a NAT firewall, comprises a proxy server serving each client and a relay server. The first proxy server may receive an invite message from a caller client to initiate a media session with a callee client. The invite message will identify the IP address and media port number of the caller client. The proxy server queries the relay server to obtain a port number of the relay server that may be used for relaying the media session between the caller client and the callee client. The proxy server will replace the IP address and port number of the caller client with the IP address and port number of the relay server in the invite message before forwarding to the callee client. When the callee client generates a response message that includes the IP address and media port number of the callee client, the proxy server will replace the IP address and media port number of the callee client in the response message before forwarding the response message to the caller client.

A coffee maker includes a body provided with a water storing space and a handle, and a heater positioned under the water storing space. The heater is made of an insulating plate and an electrically heating film formed on a lower surface of the insulating plate. Then the heat generated by the electrically heating film heats up the water in the water storing space of the body for making coffee.

A graphics system and method for processing geometry compressed, three-dimensional graphics data are disclosed. After transforming and lighting each vertex, a vertex data stream is decompressed using connectivity information, and vertexes are reassembled into geometric primitives. The connectivity information may include mesh buffer references, vertex tags, or other types of information. Independent buffers, queues, and/or caches are used to simultaneously store: (a) vertex data for the next several primitives, (b) vertex data that will be reused, (c) vertex tags, (d) control tags, (e) vertex data being assembled into a primitive, and (f) an assembled primitive ready to be launched. The assembled primitive may be clip tested for visibility in a defined viewport, before investing time to have the primitive processed into pixel data for display. The independent buffers, queues, and/or caches may also enable the vertex processing steps to be performed in parallel and at different rates.

A network station system with functions of medial register number and medical messages informing comprises a server having a memory, a CPU, and input/output devices; at least one electronic device of a medical organization; the electronic device being connected to the server; the medical messages including the current register number, the predicted treating speed, the related information about the medical organization, the working time of the doctors; a central network unit; the central network unit being connected to the at least one electronic device for receiving the information from the electronic device; these information being displayed or transferred to those needed these information; and at least one patient computer device connected to the central network unit. A patient receives information of register numbers, medical information of medical organizations and advertisements from wired or wireless transmission so as to predict the timing for going to the medical organization.

A method and computer graphics system for clip testing using clip bits stored in a general-purpose register for each vertex of a geometric primitive. In one embodiment, a rendering unit or other processor sets bits in a clip bits register for each vertex of a geometric primitive. Each bit indicates whether the vertex is inside or outside of a clipping boundary with respect to a particular clipping plane. A frame buffer controller or other graphics processor performs clip testing on the entire geometric primitive by performing Boolean operations on the clip bits. The frame buffer controller may trivially accept or trivially reject the primitive based on the clip testing. If the primitive cannot be trivially rejected or trivially accepted, then the frame buffer controller sends an interrupt to the rendering unit. The rendering unit reads an exception register to determine that the reason for the interrupt is the need to clip the primitive. The rendering unit reads the vertices from the frame buffer controller, clips the primitive, and sends the new vertices to the frame buffer controller. The frame buffer controller clears the interrupt and resumes its graphics processing.

A data queue optimized for receiving loosely packed graphics data and suitable for use in a computer graphics system is described. The data queue operates on first-in-first-out principals, and has a variable width input and output. The variable width on the input side facilitates the reception and storage of loosely packed data. The variable width output allows for the single-cycle output of multi-word data. Packing of the data occurs on the write-side of the FIFO structure.
