  • Publication number: 20070291030
    Abstract: Embodiments of a system and method including graphics processing of a pixel sample are described. According to an embodiment, a first depth test processes a value, such as a z/stencil value, of a pixel sample and determines whether the value of the pixel sample satisfies the first depth test. If the value of the pixel sample satisfies the first depth test, the value of the pixel sample is not immediately written to storage, such as a Z-buffer. That is, if the value of the pixel sample satisfies the first depth test, the depth processing logic prevents or delays a write operation for the value of the pixel sample to storage at that time. A second depth test is performed on the value of the pixel sample if the value of the pixel sample satisfied the first depth test. If the value of the pixel sample satisfies the second depth test, the value of the pixel sample is then written to storage.

  • Patent number: 7152568
    Abstract: A cylinder block for an internal combustion engine which, in use, supports a rotary crankshaft 40, the block having pairs of opposed lock width surfaces 37 formed thereon for forming an interference fit with respective co-operating lock width surfaces 38 on the crankshaft bearing caps 34 which in use are secured to respective bearing cap support surfaces 36 also formed on the block 31. The lock width surfaces 37, 38 are spaced from the respective bearing cap support surfaces 36 so as to improve stress cracking resistance of the block 31.

  • Publication number: 20060273652
    Abstract: A balance weight has a body having a cavity formed therein, a solid weight member substantially filling the cavity of the body; and an adhesive formed on a side of the body for securing the balance weight to an associated object to be balanced. A balance weight can be secured to a tire and weight assembly and has a solid body formed entirely of plastic material, wherein the body is secured to the tire and wheel assembly via an adhesive layer on one side of the body. The body can have an internal cavity formed within the body and a weight member made of metal which substantially fills the internal cavity.

  • Publication number: 20060260035
    Abstract: A skimmer door assembly for use with a skimmer having an opening therein, having a face plate for matingly engaging the skimmer around the opening of the skimmer. The face plate has an opening therein which communicates with the opening of the skimmer. A raised rib portion extends around a periphery of the opening of the face plate. A cover has a first, planar wall which closes the opening of the face plate. The cover has a groove formed on the planar wall which engages the rib of the face plate for sealing the face plate to prevent water from entering the opening of the face plate.

  • Patent number: 7017351
    Abstract: A MEMS based thermoacoustic cryo-cooler for thermal management of cryogenic electronic devices. The cryogenic cooling system can be integrated directly into a cryogenic electronic device. A vertical comb-drive provides an acoustic source through a driving plate to a resonant tube. By exciting a standing wave within the resonant tube, a temperature difference develops across a stack in the tube, thereby enabling heat exchange between heat exchangers. A tapered resonant tube improves the efficiency of the cooling system, compared with a simple cylinder configuration, leading to reduced harmonics and strong standing waves.

  • Patent number: 6700583
    Abstract: A configurable buffer has two storage areas. Depending upon a state of a buffer control signal, the two storage areas are configured to buffer a single stream of data together or to buffer two streams of data separately. In an exemplary video graphics processing application, one stream of data includes pass-through values of fragments being rendered (e.g. color, location, and/or depth values) and the other stream of data includes corresponding displaced (or otherwise perturbed) texture coordinate pairs. Such a buffer may be used to reduce the amount of buffer storage needed to support both single-pass and multipass operations in a pixel pipeline.

  • Patent number: 4831438
    Abstract: The present invention is a "tethered remote" surveillance system that uses a command and control transmitter/receiver to activate selectively a number of audio and video sensors. The system generally comprises a plurality of remote sensors which are selectively controllable through a plurality of remote integral modules to which the sensors are connected. Each integral module is a physically compact unit which includes an antenna for transmitting the outputs of the plural sensors to a command and control station and an antenna for receiving encrypted command signals from the command station. The command station includes an encrypter for generating the command signals, an antenna for transmitting the signals to the integral modules and an antenna for receiving the signals transmitted by the integral modules, as well as devices for displaying and recording the signals received.
