Abstract:
An electronic device may include a display. The display may be an organic light-emitting diode display. The organic light-emitting diode display may have a substrate layer, a layer of organic light-emitting diode structures, and a layer of sealant. Vias may be formed in the substrate layer by laser drilling. The vias may be filled with metal using electroplating or other metal deposition techniques. The vias may be connected to contacts on the rear surface of the display. Components such as flexible printed circuits, integrated circuits, connectors, and other circuitry may be mounted to the contacts on the rear surface of the display.
Abstract:
An electronic device may include housing structures, electronic components, and other structures. A gap may be formed between the structures. A membrane structure may be used to bridge the gap to form and environmental seal and electrical pathway between the structures. The membrane structure may be deployed using a temporary biasing member or may be installed by forming an inflatable structure. The inflatable structure may include an elastomeric balloon that may be pressurized. Adhesive such as conductive adhesive may be used in attaching the membrane structure to the structures in the electronic device. An inflatable structure may be depressurized following installation in an electronic device to minimize residual forces.
Abstract:
A self-righting inflatable life raft including a raft body having inflatable sidewalls and an inflatable member extending from the raft body having a buoyant portion sufficient to provide lifting force to move the raft's center of gravity beyond its point of rotation on the surface of water such that the raft will topple by gravity to an upright position. The inflatable member may include a plurality of inflatable tube portions which extend from an upper edge of the raft sidewalls to a first predetermined position upwardly and outboard from the upper edge and which then extend inboard to centrally converge with one another at a second predetermined position above the raft body.
Abstract:
An electronic device may have a display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The backlight structures may include a light guide plate that distributes light across the display layers. A light source such as a light-emitting diode light source may be used to provide light to the light guide plate. The light source may overlap an edge portion of the light guide plate. A light guide structure having a bend may be coupled between the light source and the light guide plate. The light guide structure may be used to guide the light from the light source to the light guide plate via total internal reflection. A light guide structure may be provided with light leakage promotion structures to evenly distribute light from a centralized light source along the edge of a light guide plate.

Abstract:
A device is provided for increasing fluid pressure, the device having a first conduit having a fluid inlet and outlet, the first conduit provided with a non-return valve and a second, bypass, conduit having bypass inlet and by pass outlet connected to the first conduit either side of the non-return valve, which bypass is provided with a pumping means. The pump may be sized such that the device can deliver a high pressure of fluid to a low flow-rate demand outlet downstream thereof whilst the device allow a high flow-rate demand downstream of the device to be supplied at low pressure as and when required resulting in a much cheaper, more efficient and more durable pumping arrangement, useable in several applications.
Abstract:
An electronic device may have polarizer layers, color filter layers, thin-film-transistor layers, and other display layers. A display layer may be separated from structures such as a display cover layer formed from clear glass or plastic and a touch sensor layer mounted on an inner surface of the display cover layer by an air gap. Cavities within an electronic device housing may serve as a source of dust and other contaminants. The air gap may be sealed against dust intrusion from a cavity within an electronic device using a dust sealing structure. The dust sealing structure may have a rectangular ring shape that runs around a rectangular peripheral portion of a display layer. The dust sealing structure may be formed from a tape-based structure, an elastomeric structure, a compressible foam structure, or a cured liquid structure.
Abstract:
An electronic device may have a liquid crystal display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The display layers may include a layer of liquid crystal material interposed between a color filter layer and a thin-film transistor layer. The backlight structures may include a light guide plate. A plurality of light-emitting diodes mounted on a flexible printed circuit may be coupled to an edge of the light guide plate. The flexible printed circuit may be curled into a spring element to bias the light-emitting diodes against the edge of the light guide plate. A plurality of gaps may be formed in the flexible printed circuit and may be used to separate and mechanically decouple adjacent light-emitting diodes. Individual light-emitting diodes may independently register to the light guide plate to maximize optical efficiency in the display.
Abstract:
An apparatus for self-righting a rigid inflatable boat in which the boat includes an elongated hull having a determinable center of gravity and beam width. The boat hull has an elongated rigid bottom and inflatable sidewalls which have top, bottom and inner edges. An inflatable arch member having first and second leg portions extending upwardly and inboard from opposite sidewalls of the hull converges at a central point spaced outwardly a first predetermined vertical distance above the top edges. The first predetermined distance is at least equal to the sum of one-half of the beam of the hull, plus a distance equal to the vertical distance, if any, at which the center of gravity may be located above the sidewalls' bottom edges. Each leg portion has an axial centerline which extends upwardly and inwardly substantially between its respective sidewall and the central point. Each axial centerline passes vertically above the inner edge of its respective sidewall at a vertical level above the bottom edge a distance equal to at least one-half of the vertical distance between the central point and the bottom edge. The inflatable arch member is sized to have an overall width substantially not greater than the beam of the boat and to provide a total displacement sufficient to lift the boat. The arch member is positioned along the elongated boat hull aft of the center of gravity.
