  • Publication number: 20220303134
    Abstract: An onboard communication network of a vehicle is monitored to detect a plurality of available messages that include respective cipher-based message authentication codes (CMAC) and that were identified as eligible messages based on having an information entropy greater than a specified threshold. A first message is selected from the plurality of available messages. The CMAC of the selected message is input into a random number generator that outputs a random number seeded by the CMAC of the selected message. Then the random number is provided.

  • Publication number: 20100124596
    Abstract: An insulated cover and method that makes it possible to create a thermal environment on a home gas or charcoal grill similar to that produced by a wood fired brick oven or commercial pizza oven. The cover is made from a high temperature resistant, thermal insulation material that is encapsulated (sandwiched) between thin metal sheet or metal foil skins. The insulated cover covers both a food support surface that has been placed on the grill's grate directly over the grill's heat source and the remainder of grills grate area that is suspended directly above the grills heat source that is not already covered by the food support surface. The food items are cooked from below by the thermal energy stored in the food support surface, and from above by the thermal energy contained within the low volume zone created by the insulated cover resulting in uniform, fast, even and energy efficient cooking of food items like pizza.

  • Publication number: 20070031702
    Abstract: Erosion resistant coating processes and material improvements for line-of-sight applications. The erosion resistant coating composition includes nanostructured grains of tungsten carbide (WC) and/or submicron sized grains of WC embedded into a cobalt chromium (CoCr) binder matrix. A high velocity air fuel thermal spray process (HVAF) is used to create thick coatings in excess of about 500 microns with high percentages of primary carbide for longer life better erosion resistant coatings. These materials and processes are especially suited for hydroelectric turbine components.

  • Patent number: 7167969
    Abstract: An apparatus and method provides the capability of mirroring storage from a primary system to a mirrored system in a way that uses parallelism in the mirrored system to maximize the efficiency of writing data to the mirrored storage for operations that do not conflict while serializing operations that do conflict. The mirroring of the present invention is “logical mirroring”, which does not require identical disk drives, and which supports mirroring between geographically remote locations to protect against catastrophic site failure. Parallelism is achieved in the mirrored system by dividing the virtual address space into multiple ranges, and by assigning a group of tasks to each range. When an operation is received on the mirrored system, the virtual address range that the operation affects is determined, and the operation is then delegated to the task group that corresponds to the affected virtual address range. By dividing the virtual address space into ranges, tasks in different ranges (i.e.

  • Publication number: 20050260434
    Abstract: A bi-layer bond coating for use on metal alloy components exposed to hostile thermal and chemical environment, such as a gas turbine engine used to generate electricity and the method for applying such coatings. The preferred coatings include a bi-layer bond coat applied to the metal substrate, with both layers being applied using high velocity oxy-fuel (HVOF) thermal spraying. In one embodiment, bond coatings in accordance with the invention can be used in combination with a thermal barrier coating (“TBC”). However, the invention can also take other forms, such as a stand alone overlay coating. Bi-layer bond coatings in accordance with the invention consist of a dense first inner layer (such as iron, nickel or cobalt-based alloys) that provides oxidation protection to the metal substrate, and a second outer layer having controlled porosity that tends to promote roughness, mechanical compliance, and promotes adherence of the TBC.

  • Patent number: 6699101
    Abstract: A method of removing the damaged surface layer beneath a coating on a component. The method includes evaluating the component to assess the depth of the damaged substrate layer, followed by sensing a plurality of points over the outer surface of the component to determine a three-dimensional outer surface profile thereof. A three-dimensional grinding profile beneath the outer surface profile is then established based on the depth of the damaged substrate layer beneath the outer surface profile. The component is then ground along the grinding profile such that the damaged substrate layer is substantially removed without significantly removing an undamaged region of the substrate beneath the damaged substrate layer.

  • Patent number: 5419971
    Abstract: An article having a substrate is protected by a thermal barrier coating system. An interfacial layer contacts the upper surface of the substrate. The interfacial layer may comprise a bond coat only, or a bond coat and an overlay coat. The interfacial layer has on its upper surface a preselected, controllable pattern of three-dimensional features, such as grooves in a parallel array or in two angularly offset arrays. The features are formed by an ablation process using an ultraviolet laser such as an excimer laser. A ceramic thermal barrier coating is deposited over the pattern of features on the upper surface of the interfacial layer.

  • Patent number: 4147581
    Abstract: An improvement in an etching process in which the etched product, the surface of which is covered with a film of aqueous etching liquid containing ions of the material etched, is rinsed with an aqueous liquid and the resulting liquid, now containing said ions in dilute concentration, is passed through an ion exchanger to selectively remove the ions from the rinse liquid which thereupon can be reused or discharged, without ecological damage, from the ion exchanger. The ion exchanger when laden with such ions is regenerated by passage therethrough of at least a portion of an etcher make-up aqueous replenishing solution which contains a zero or low concentration of said ions. The resulting replenishing solution portion, now containing a small concentration of these ions, is passed to the etcher, e.g., to the etcher sump.
