  • Patent number: 6627323
    Abstract: A protective coating system and method for protecting a thermal barrier coating from CMAS infiltration. The coating system comprises inner and outer alumina layers and a platinum-group metal layer therebetween. The outer alumina layer is intended as a sacrificial layer that reacts with molten CMAS, forming a compound with a melting temperature significantly higher than CMAS. As a result, the reaction product of the outer alumina layer and CMAS resolidifies before it can infiltrate the TBC. The platinum-group metal layer is believed to serve as a barrier to infiltration of CMAS into the TBC, while the inner alumina layer appears to enhance the ability of the platinum-group metal layer to prevent CMAS infiltration.

  • Patent number: 6356262
    Abstract: The visibility ordering of polyhedral cells is efficiently determined by building an ordering graph, comprising oriented edges between two cells. Each edge (A,B) corresponds to the fact that cell A has to be projected, or rendered, before B. A set of ordering relations and rules that can be shown to generate, if one exists, a global ordering of the polyhedral cell complex. Three different types of edges are used to accomplish this: MPVO, BSP and PPC edges. MPVO edges exist between two cells that share a face. To define the BSP edges, a BSP-tree of the boundary faces of the cell complex is constructed. During this construction, some of the boundary faces of the cells will be ‘cut’ by the BSP-tree ‘extended’ faces, into multiple pieces. If C is the boundary cell, and c′, c″, and so on, are the pieces of its boundary faces, the BSP_edge (c′, C) is defined to mean that cell C can only be projected after c′ has been projected by the BSP.

  • Patent number: 6307388
    Abstract: An electromechanical apparatus for testing integrated chips includes a chip holding subassembly, a power converter subassembly, and a temperature regulating subassembly, which are squeezed together in multiple sets, by respective pressing mechanisms. One benefit which is achieved with this electromechanical apparatus is that by pressing the temperature regulating subassembly against the chip holding subassembly, heat can be added/removed from the chips by conduction; and thus the temperature of the chips can be regulated accurately. Another benefit which is achieved with this electromechanical apparatus is that by pressing the power converter subassembly against the chip holding subassembly, the distance between the chips that are tested and the power supplies for those chips is made small. Consequently, the chip voltages can easily be kept constant while the chip power dissipation changes rapidly as the chips are tested.

  • Patent number: 6298087
    Abstract: A variable length code decoder includes modified VLC decode tables as compared to table b.14 and b.15 of Annex B of the ISO/IEC 31818-2 standard, and improved program code for inverse quantising block DCT coefficients. The modified VLC decoding tables include level values corresponding to VLC coded words that have been pre-multiplied by the value 2, or by 2 then plus 1. As a result, the modified tables of the present invention reduces the computational complexity of the inverse quantization calculation of the method of the present invention as compared to the algorithm provided in ISO/IEC 31818-2, section 7. Advantageously, the bandwidth requirement of the inverse quantiser processor is reduced as compared to the bandwidth requirement of an inverse processor executing the inverse quantization calculation as defined in the Standard. Conveniently, lower cost, and more widely available processors may be used in the decoder of the present invention.

  • Patent number: 6196299
    Abstract: A mechanical assembly for regulating the temperature of a chip is comprised of a heat exchanger which has a face for mating with a planar surface on the chip. A frame is coupled to the heat exchanger such that the face of the heat exchanger is exposed and can contact the planar surface of the chip. And, the face of the heat exchanger has a shape which makes contact with the entire planar surface on the chip except for each of its corners. One particular embodiment of the heat exchanger has four grooves which extend from the face and which respectively align with the corners of the chip. Due to those grooves, initial contact between the face on the heat exchanger and the planar surface on the chip occurs on an edge of the chip which is spaced-apart from a corner. Consequently, the chance of breaking the tip of a corner off of the chip is reduced.

  • Patent number: 5935211
    Abstract: A computer-implemented method uses out-of-band notifications to reduce overhead associated with notifying a client process of events that have occurred at a server process in a computer system employing a request-response protocol. Initially, a notification transmission connection is established between the client process and the server process using the request-response protocol. Thereafter, notifications are transmitted from the client process to the server process using the connection, and without using the request-response protocol to transmit the notifications.

  • Patent number: 5911595
    Abstract: The electrical connector of this invention is for terminating the wires of a cable into an electrical insert positioned within a connector backshell at an angle to the direction of the cable. A wireing space at the rear of the backshell is provided to terminate the wires within the insert. The connector is used to provide a connector interface for a cable running along one surface of a bulkhead and turning at an angle through the bulkhead to a receptacle or connector face extending from the other face of the bulkhead. The connector face receives an associated electrical interface device. The electrical connector of this invention provides the connector in a minimum amount of clearance space on both sides of the bulkhead. Grounding and shielding of a shielded portion of the cable to the connector is also provided within the minimum clearance space. A tie cord attaches the wires of the cable to a neck of the hollow shaft of the connector backshell to provide stress relief for the wires.
