  • Patent number: 8768500
    Abstract: Methods, apparatuses and systems that facilitate the design, production and/or measurement tasks associated with manufacturing and other processes. In one embodiment, the present invention provides an understanding of how the multiple characteristics of a given process output are related to each other and to process inputs. This knowledge facilitates a reduction in measurement costs. It also facilitates an understanding of the sometimes complex interrelationships between design targets, design tolerances, process inputs, process control variables, average process output and variation in the process output. As discussed in more detail below, embodiments of the present invention facilitate 1.) determination of design target values, 2.) determination of design specification limits, 3.) design of process inputs, 4.) determination of process control variable settings, and/or 5.) reduction of measurement costs.

  • Patent number: 8761957
    Abstract: A method of decreasing a transition time through a speed range that is unsafe for an integrity of a first expander, by automatically biasing a speed of a second expander that receives a fluid flow output from the first expander is provided, when the current speed of the first expander is within a bias application range. The method includes setting the speed of the second expander to be larger than a current speed of the first expander when the current speed of the first expander increases and is smaller than a first speed value, or decreases and is smaller than a second speed value, and setting the speed of the second expander to be smaller than the current speed of the first expander, when the current speed of the first expander increases and is larger than the first speed value or decreases and is larger than the second speed value.

  • Patent number: 8718835
    Abstract: An optimized temperature-driven device cooling mechanism factors in power consumption of thermal management components, as well as processing components. A decision engine consults a knowledge base comprising information regarding power consumption and thermal impact of cooling components and processing components. The decision engine can delay additional cooling if the power consumption of cooling components is greater than the increase in power consumption of processing components due to increases in ambient temperature. The knowledge base is populated by published specifications and by empirically derived data that can be based on tests performed on components. Thermal management strategies can be user selected and can include strategies that avoid controlling certain components such as, for example, processing components, instead focusing only on cooling and other components. Cooling includes heat distribution, such as by transferring processing from one processing component to another.

  • Patent number: 8718812
    Abstract: A method of making an aerofoil blink comprising a plurality of aerofoil blades joined to a disc to extend radially outwardly therefrom is provided. The method includes the step of: (a) modelling a linear friction welding process in which a blade member is joined to the disc, the blade member having a stub for joining to the disc, wherein the modelling provides results which are indicative of the welding power at positions along the stub during the welding process; (b) identifying adaptations to the stub using the modelling results to compensate for differences in welding power along the stub during the welding process; (c) providing a blade member having a stub with the identified adaptations; and (d) joining the provided blade member to the disc by the linear friction welding process.

  • Patent number: 8712557
    Abstract: A program editor creates a program-edit screen for a control system based on element data for representing circuit elements and operators and their attribute values. Here, the circuit elements and operators are components of sequential programs which constitute functions of the control system. The program editor which edits the element data on the created program-edit screen judges whether the data for representing the circuit elements and the operators is protected-function data or non-protected-function data and displays assembly sets of programs for implementing predetermined functions constituted by circuit elements and operators to which accesses are authenticated on the program-edit screen in a display mode different from those of the other assembly sets.

  • Patent number: 8655497
    Abstract: A method for regulating electrical and thermal power generated by an energy system in a multi-source energy plant that comprises one or more loads. The energy system comprises an electronic unit implementing a multi-objective function (Fmo) that comprises: first computation parameters (PTi, Oi) comprising values of the electrical and thermal powers exchanged within the multi-source plant between a cogeneration module, loads, auxiliary sources and an electric network; and a set of second (Ci, Ai) and third computation parameters (Ni) correlated to the costs of management and exchange of the electrical and thermal powers within the energy plant. The method comprises the step of determining optimal values (PUi) of the electrical and thermal powers that the energy system must supply to minimize the multi-objective function (Fmo), and the step of varying the electrical and thermal powers generated by the cogeneration module as a function of the optimal values calculated (PUi).
