Abstract: Disclosed herein is a hybrid mechanical/reactive pressure prevention system that includes a passive pressure control device operably coupled to a door that allows air within a pressurized vehicle to flow out of the pressurized vehicle. An event module detects a door event in the pressurized vehicle. The door event indicates that a door is not secure and air within the pressurized vehicle is being released through the passive pressure control device. An altitude module determines an altitude of the pressurized vehicle in response to detecting the door event. An electronic pressure control device one or more of reduces air inflow into the pressurized vehicle and increases air outflow out of an active pressure control device of the pressurized vehicle in response to the altitude of the pressurized vehicle being below a cutoff altitude.

Abstract: A method and apparatus for a tracking door centering system. An apparatus may comprise an elongate member, a first centering track, and a second centering track. The elongate member may have a first end and a second end capable of being rotatably mounted to a door along an axis that may be substantially parallel to a horizontal centerline. The first centering track may be mounted on the first end. The second centering track may be mounted on the second end. The first centering track and the second centering track may be movable to reduce rotational movement of the door during movement of the door about a vertical centerline when a first follower is engaged in the first centering track and a second follower is engaged in the second centering track.

Abstract: A reflective diffusion lens may include a bottom surface concave toward a reflective surface, a longitudinal cross section of the bottom surface being formed in a parabolic shape or normal distribution shape such that light incident upon the bottom surface is incident upon the reflective surface, and the reflective surface concave toward the bottom surface. The reflective surface may include a concave surface having a longitudinal cross section formed in a parabolic shape or normal distribution shape to totally reflect the light transmitted from the bottom surface and incident upon the reflective surface. A lighting installation may include at least one light source to emit light, a reflective diffusion lens to collect light emitted from the light source, and a reflective plate positioned at a lower portion of the light source and adapted to adjust a direction or amount of light reaching the reflective plate.

Abstract: A back light unit and a manufacturing method thereof capable of improving efficiency of a manufacturing process are disclosed. The back light unit includes a light source, a light guiding plate which uniformly transmits a light beam generated by the light source, and a cover portion which forms an external appearance and fixes the light guiding plate, wherein a resin material is charged between the light guiding plate and the cover portion to couple the light guiding plate and the cover portion.

Abstract: A back light unit, in which bright lines produced from point light sources, light emitting diodes, in an oblique direction are removed, so that brightness can be uniformly maintained at a liquid crystal panel. The back light unit includes a prism light guide plate, light emitting diodes provided on one side of the prism light guide plate, and a bright-line dead section provided to the prism light guide plate so as to uniformly scatter light of each light condensing section generated by light emitted from the light emitting diodes, to prevent a spectrum of the light in a specific direction, and to prevent bright lines from being produced.

Abstract: A backlight unit usable in an LCD includes a point light source circuit board, a plurality of point light sources seated on the point light source circuit board, and a diffusion lens provided on each point light source and comprising a depressed point and a curved surface radially protruding from the depressed point.

Abstract: A device for transmission/reception of a facsimile data in a separate type WLL system is provided, in which an analog G3 facsimile signal is converted into a CDMA signal format for transmission/reception of the signal. The device includes an interface unit for transmitting facsimile data produced at a facsimile, or matching data received in an analog facsimile protocol to wire line characteristics for providing the data to the facsimile, a facsimile signal processor for receiving the facsimile data from the interface unit and converting it into a digital signal and a radio data service format, or receiving a data in a radio data service format, converting it into an analog facsimile protocol, and forwarding it to the interface unit.

Abstract: An overcenter mechanism (10) includes a housing (12) and a first shaft (14) mounted on the housing. The first shaft has a first axis (34). A second shaft (20) is mounted on the housing and the second shaft has a second axis (41) that parallels the first axis. A lever (16) is attached to the first shaft, and the lever pivots about the first axis in response to a force (F.sub.op) applied to the lever. A cam (18) is attached to the first shaft, and the cam pivots about the first axis. The cam has a cam surface including a first surface portion (58) and a second surface portion (60). The first and second surface portions form a cusp (62) therebetween. A cam follower (21) has a cam follower surface, and the cam follower pivots about the second axis. A biasing member (26) urges the cam follower surface against the cam surface in pressure contact. The cam follower and the pressure contact cooperate with the cam to generate torque (.tau..sub.roller) on the cam until the cam follower surface contacts the cusp.
