Abstract: A method includes transmitting, by a controller of a storage device, a first bit on a data line. The method further includes responsive to transmitting the first bit on the data line, determining, by the controller, a line level of the data line. The method further includes responsive to determining the line level of the data line, determining, by the controller, whether the line level of the data line corresponds to the first bit and responsive to determining that the line level of the data line does not correspond to the first bit, determining, by the controller, that a collision has occurred on the data line.

Abstract: A system and method provide fail-safe operation of a lighting system. A lighting level detector is used to obtain a baseline lighting level for a low-intensity light. If the detector measures less than the baseline level when an occupancy sensor determines the space is unoccupied, a high-intensity light is energized and an indication is provided to a user that the low-intensity light has failed. A method provides daylighting operation of a lighting system. An occupancy sensor can have Wi-Fi functionality to enable remote configuration of the sensor. A line voltage occupancy sensor can include an interface with low voltage devices. An occupancy sensor can include an integral interface to enable an external control system to override the sensor's normal logic under emergency conditions. An occupancy sensor can include an active temperature compensation feature. An occupancy sensor can also incorporate an automatically adjustable coverage area.

Abstract: A device for opening and closing a movable window of a motor vehicle, the movable window being movable relative to a fixed panel, from a closed position in which the movable window is positioned flush with the fixed panel, to an open position in which the movable window is moved parallel to the fixed panel. The device includes an assembly controlled from a handle mechanism supported by an edge of a frame secured to the movable window, such that starting from the closed position, actuating the handle a first time releases locking of the movable window then, secondly, brings the movable window out of its closed position, an edge of the window corresponding to the edge of the frame being moved relative to the fixed panel, to the position allowing sliding of the movable window.

Abstract: A combustion chamber arrangement has an annular outer wall and an annular inner wall having an upstream row of tiles and a downstream row of tiles. The outer wall has a concave bend which is less than 175°. The downstream end of the upstream tiles and the upstream end of the downstream tiles are adjacent the concave bend. The downstream ends of the upstream tiles are spaced at a greater distance from the inner surface of the annular outer wall than the upstream end of the downstream tiles. The upstream tiles have curved lips extending in a downstream direction which overlap but are spaced radially from the upstream ends of the downstream tiles. The outer wall has a row of apertures to direct coolant onto the outer surfaces of the curved lips and the upstream tiles has a row of apertures extending to the inner surfaces of the curved lips.

Abstract: An airblast fuel injector for the combustor of a gas turbine engine has, in order from radially inner to outer, a coaxial arrangement of an inner swirler passage, an annular fuel passage, an annular mid swirler passage, and an annular outer swirler passage. The fuel passage extends to a prefilming lip, and the inner and mid swirler passages swirl air past the prefilming lip so that fuel fed from the fuel passage to the prefilming lip is entrained by the swirling air into a fuel spray stream. The outer swirler passage has a convergent portion. The radially inward wall of said convergent portion is defined by a frustoconical separator element which separates the outer swirler passage from the mid swirler passage, the separator element converging in the direction of air flow to terminate in a lip at the mouths of the mid swirler passage and the outer swirler passage.
