摘要:
Architecture that expresses scene composition and animation in a form that can run entirely on the graphics processing unit (GPU). The architecture stores retained graph information (e.g., scene graph and animation information) as texture information, and uses shaders (e.g., vertex and pixel) to evaluate time information, evaluate animation, evaluate transforms, and rasterize paths. Additionally, the architecture provides the ability to compute animation positions and redraw entirely on the GPU without per primitive CPU intervention.

Various technologies and techniques are disclosed for controlling a shader declaratively. A declarative programming model enables declarative statements to be used that control an instantiation of a shader in a declarative presentation framework. A shader-based effect that was specified declaratively is instantiated programmatically for rendering graphic effects for a software application. Declarative statements are sent to a shader processor to enable a shader to render the graphical effect customizations for the software application. A method is also described for utilizing a declarative programming model as a multiple pass effect that controls and encapsulates a set of shaders to be run during a multiple pass operation.

A sensor element is described for determining a physical property of a measuring gas, in particular the pressure or the concentration of a gas component in a gas mixture, in particular in the exhaust gas of an internal combustion engine. The sensor element has an electrode exposed to the measuring gas and a reference electrode exposed to a reference gas, ambient air in particular, through a porous volume. The two electrodes are separated from one another by a solid electrolyte. To avoid premature aging of the reference electrode as a result of deposits of foreign substances contained in the reference gas or of chemical interactions caused by the foreign substances, the volume material is selected with respect to its physical and chemical properties in such a way that the foreign substances are bound in the volume and/or are subjected to a chemical reaction.

An antenna system for a radio frequency (“RF”) wireless keyboard includes a metallic plate as a part of the antenna system. The metallic plate is located within the wireless keyboard. A RF transmitter is coupled to the metallic plate and an antenna wire which form an the antenna loop. The antenna loop may also be directly integrated into the metallic plate by creating a cut-out space in the metallic plate. The antenna system may also include the metallic plate directly coupled with the RF transmitter so that the metallic plate is a whip or dipole antenna. The RF transmitter generates RF signals associated with particular keyswitches of the wireless keyboard. The antenna system transmits the generated RF signals to a RF receiver that resides separately from, and that communicates with, the wireless keyboard.

The case of maintainability and component replacement for a vacuum processing chamber is enhanced by providing a vacuum chamber roof assembly whose connection to the vacuum chamber body is through a clamped connection. Accessories needed for the roof assembly, e.g. cooling, heating, RF power, are separately supported and terminated to an accessories supporting cold plate, which is separately mounted such it is easily movable, for example by hinging from the chamber body. The roof of the chamber can then easily be separated from the chamber body and replaced. In an further mode the chamber roof can be easily raised to provide easy access to modular components inside the processing chamber. All components exposed to the plasma in the chamber can be easily accessed and replaced. Moreover, such access is provided without the need to disconnect utilities or instrumentation, since the release of a latch and pivoting the cold plate assembly away from the chamber body upwards is all that is needed to gain access to either the top of the roof of the processing chamber or the inside of the chamber. Chamber roof cooling is provided through a separable connection which is spring clamped to provide a high confidence that uniform thermal conductivity across a clamped joint is maintained.

In accordance with a first aspect of the invention, a plasma reactor having a chamber for containing a plasma and a passageway communicating with the chamber is enhanced with a first removable plasma confinement magnet module placed adjacent the passageway including a first module housing and a first plasma confinement magnet inside the housing. It may further include a second removable plasma confinement magnet module placed adjacent the passageway including a second module housing, and a second plasma confinement magnet. Preferably, the first and second modules are located on opposite sides of the passageway. Moreover, the first and second plasma confinement magnets have magnetic orientations which tend to oppose plasma transport or leakage through the passageway. Preferably, the module housing includes a relatively non-magnetic thermal conductor such as aluminum and is in thermal contact with said chamber body. Cooling apparatus can be thermally coupled to the chamber body, whereby to maintain the first plasma confinement magnet below its Curie temperature. If the reactor includes a pumping annulus adjacent of a periphery of the chamber, then the passageway can be one which communicates between the chamber and the pumping annulus. Also, the passageway can be a wafer slit valve or a gas feed inlet. Such a gas feed inlet can be a center gas feed through a ceiling of the chamber. The module housing can rest upon the chamber side wall and the chamber ceiling can rest upon the module housing.

A device for cleaning dirty objects, for example dirty textiles or dishes, is characterized by a fluid-proof housing (8) immersible in water together with the dirty objects and made to vibrate by means of a drive mechanisms (12; 46). The vibrations may be generated by means of an unbalance weight (26) driven by an electromotor (12), the electromotor (12) and the unbalance weight (26) being arranged inside said housing (8). A charging device for the device (2) comprises a housing (98), with a column-shaped extension being formed on the housing, the outer section of which matches essentially without a gap with the inner section of a receiving chamber of the housing (8) of the device, and an inductive transmitter coil being furthermore arranged inside said extension.
摘要:
A sensor element for determining concentration of at least one constituent of a gas mixture operates on an electro-chemical measuring process and includes a gas measuring chamber; a pair of electrodes and an electrode chamber located between the pair of electrodes; and a diffusion conduit adjoining the electrode chamber and having a gas input which connects with the gas measuring chamber, having a gas output which connects with the electrode chamber, and having at least one cross-sectional area including a height, w, and a length, L, which height, w, has a preselected minimum value, and which length, L, has a value which is equal to or greater than the preselected minimum value of the height, w. The constituent of the gas mixture has a mean free path length through the sensor element, the gas measuring chamber has a cross-sectional area including a height and a length each of which are at least as large as the minimum height, w, of the diffusion conduit, and the height, w, of respective ones of the at least one cross-sectional area of the diffusion conduit is at least a multiple of the mean free path length of the constituent of the gas mixture to be measured. Advantageously, substantially only gaseous phase diffusion occurs when the predetermined minimum value of the height, w, is at least a multiple of a minimum value of the mean free path length for the gas constituent measured.
