    Abstract: A method includes routing a combustion gas through a turbine stage along a combustion gas path disposed between a turbine shaft and a turbine casing of a gas turbine, wherein the turbine shaft is disposed along a rotational axis, the turbine casing is disposed circumferentially about the turbine shaft, and the turbine stage includes a plurality of turbine vanes disposed upstream from a plurality of turbine blades. The method includes controlling an axial range of different axial positions of combustion within a turbine stage expansion of the turbine stage to reduce temperature variations over the turbine stage expansion via an isothermal expansion system coupled to the turbine stage in response to a change in a load on the gas turbine.

    Abstract: Printed circuit boards (PCB) used to mechanically and electrically connect electrical components within an electronic device. Thin printed circuit boards (PCB) may be desirable to manufacturers and users of electronic devices. Accordingly, a process for manufacturing a printed circuit board may involve manufacturing a thin bilayer dielectric. The process may involve applying a first non-conductive layer to a metal substrate, and curing the first non-conductive layer to a C-stage resin layer that is fully cross-linked layer in a clean environment. In turn, a B-stage layer that is partially cured may be applied to the C-stage resin layer. Using a hot press, one or more metal traces may be pressed onto the B-stage layer. The B-stage resin layer may be fully cross-linked and integrated with the C-stage resin layer after lamination of the one or more metal traces and the B-stage resin layer.

    Abstract: Circuits, systems, methods, and devices are provided for isolating the first ground domain from the second ground domain while transmitting and receiving data between the two ground domains. The proposed high-voltage ground-isolating level shifter may be formed by AC coupling capacitors and a memory cell. The circuit under the high voltage ground domain may be located in an engineered high-voltage isolation well with a relatively large breakdown voltage.

    Abstract: An electronic device may include an electronic display to display an image based on compensated image data in a panel space. The electronic device may also include image processing circuitry to generate the compensated image data. Further, generating the compensated image data may include determining a first inverse mapping of a pixel grid from the panel space to a rendering space and determining a forward mapping of the pixel grid from the rendering space to the panel space based on the first inverse mapping. The forward mapping may include corrections for multiple different warp operations stacked in a single warp operation. Additionally, the image processing circuitry may apply the forward mapping to input image data to generate the compensated image data.

    Abstract: Methods and systems (100) for modeling operations of a physical plant (110) are presented. For instance, a system (100) includes at least a first component (111) and a second component (112). The first and second components (111), (112) have at least one physical connection (130a). First and second model operational parameters of the physical connection are received from first and second models 121, 122, respectively. The first and second models (121), (122) are updated with the second and first model operational parameters, respectively. In one example, the first and second models (121), (122) run on different computer systems. In another example, real-time operational data is received from the first and second components (111), (112), and the first and second models (121), (122) are updated with the real-time operational data received from the second and first components, respectively. In a further example, the system (100) may receive and process simulation input. In various examples, the physical connections (130a) may include a material stream, a rotating shaft or a control signal.

    Abstract: A tool includes a first body portion having opposite first and second recesses facing toward one another about a space, wherein the opposite first and second recesses are configured to contact opposite sides of a first component disposed in the space. The tool includes a second body portion configured to rotate relative to the first body portion, wherein the second body portion is configured to contact a reference surface relative to the first component. The tool further includes an angle meter configured to measure an angle of the first component based on an angular position of the second body portion relative to the first body portion.
