  • Patent number: 10605683
    Abstract: A pressure sensor arrangement includes a tube with a diaphragm to pressure to be measured is applied arranged in the cross-section of the tube, wherein the diaphragm is fastened to the tube inner wall via an articulation extending along the circumferential region of the diaphragm, where deformation of the diaphragm results in rotation of the articulation directly on the wall of the tube which can therefore be detected from the outside by suitable structure such that that strain sensors, for example, which can be used to detect deformation are advantageously not in contact with the process medium and there is advantageously no need for a pressure-tight bushing for electrical signals, and where the pressure sensor arrangement has a particularly simple structure and can be advantageously used in measuring transducers for process instrumentation.

    Abstract: A porous member is used in a liquid removal system of an immersion lithographic projection apparatus to smooth uneven flows. A pressure differential across the porous member may be maintained at below the bubble point of the porous member so that a single-phase liquid flow is obtained. Alternatively, the porous member may be used to reduce unevenness in a two-phase flow.

  • Publication number: 20200040784
    Abstract: The invention relates to a method for the exhaust aftertreatment of an internal combustion engine, which on the outlet side is connected to an exhaust gas system. Provided in the exhaust gas system is at least one exhaust aftertreatment component with which, upon reaching the light-off temperature of this exhaust aftertreatment component, the gaseous limited exhaust gas components may be converted into unlimited exhaust gas components. An introduction point is provided at an exhaust duct of the exhaust gas system, at which a hot gas, in particular an exhaust gas of an exhaust gas burner, is introduced into the exhaust duct. The hot gas mixes with the exhaust gas of the internal combustion engine in such a way that a hot mixed gas results in which the unburned exhaust gas components are oxidized to unlimited exhaust gas components, without a catalytically active surface.

  • Patent number: 10553141
    Abstract: A system for maintaining a substantially constant display white point over an extended period of operation of a color display formed by an array of multiple pixels in which each of the pixels includes multiple subpixels having different colors, and each of the subpixels includes a light emissive device. The display is generated by energizing the subpixels of successively selected pixels, and the color of each selected pixel is controlled by the relatives levels of energization of the subpixels in the selected pixel. The degradation behavior of the subpixels in each pixel is determined, and the relative levels of energization of the subpixels in each pixel are adjusted to adjust the brightness shares of the subpixels to compensate for the degradation behavior of the subpixels. The brightness shares are preferably adjusted to maintain a substantially constant display white point.

  • Patent number: 10527855
    Abstract: Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described. An optical device comprises an optical waveguide including a volume of optically transparent material having a first longitudinal surface positioned opposite a second longitudinal surface across a width of the volume, a liquid crystal in-coupler, a controller to modulate a refractive index of the liquid crystal in-coupler, and an out-coupler. Light is in-coupled into the waveguide on a path that is dependent on the modulated refractive index of the liquid crystal in-coupler and is propagated along a length of the waveguide by total internal reflection between the longitudinal surfaces before being out-coupled by the out-coupler. In this way, light signals can be steered to create an image and/or to move an exit pupil of an image. WHUDs that employ such optical waveguides are also described.

  • Publication number: 20190392163
    Abstract: Systems, devices, and methods are disclosed for enabling private communication between head-mounted displays. A first user dons a first head-mounted display. The first head-mounted display authenticates that the first user is authorized to view information displayed by the first head-mounted display. In response to positive authentication, the first head-mounted display displays the information to the first user. The first user inputs a selection command via an input interface, such as, for example, gazing at particular information, to select some of the displayed information. The first head-mounted display generates a message based on the user selection, which may be encrypted by the first head-mounted display prior to transmission. The first head-mounted display transmits the message to a second head-mounted display, such that the second head-mounted display displays the message to an eye of a second user wearing the second head-mounted display.
