The system includes an exterior radio frequency coupling module having a plate and a shield electrically coupled to the plate. The exterior coupling module also has a conductive member electrically isolated from the plate and the shield. The system also includes an interior radio frequency coupling module having a plate and a shield electrically coupled to the plate. The interior coupling module includes a conductive member electrically isolated from the outer conductor and a shield. The exterior coupling module is affixed to one side of the dielectric panel and the interior coupling module is affixed to another side of the dielectric panel in juxtaposition to the exterior module. Both conductive members of the exterior and interior module contact the dielectric panel.

Abstract: A security camera has an adjustable turret that holds a lens assembly which can be aimed in various directions. The camera also has a compact housing which, in combination with the adjustable directionality of the turret, enables universal mounting to various structures and positions in an aircraft cabin. The camera operates in light and dark conditions, as the lens assembly is configured to focus visible and infrared light wavelengths onto a fixed focal plane. In an embodiment, the camera includes an infrared illumination source to illuminate a field of view during dark conditions. The lens assembly includes a rigid barrel with a pinhole aperture through which light enters a series of lens elements. An optical sensor is mounted to an opposite end of the barrel at the fixed focal plane to generate an electronic image signal, and the sensor is rotatably adjustable to yield a correct image orientation depending on the turret position.

Abstract: Provided is an automatic focusing method used by a digital image processing apparatus including a zoom lens moving in a moving range of a first guide bar and a focus lens moving in a moving range of a second guide bar disposed on an extension of the first guide bar. The method includes performing focusing while moving the zoom lens in a range from a zooming limit position in the first guide bar to a set zoom limit position, if a current photographing mode is a close-range photographing mode and a current position of the zoom lens is the zooming limit position.

Abstract: A support frame for a seat, in particular an aircraft seat, where the support frame includes a seat support member having an upper surface and a lower surface, a plurality of leg members that each have a first end and a second end, with the first end attached to the lower surface of the seat support member. An angled flexible leg brace capable of stretching to absorb a dynamic load on the frame extends between at least two of the plurality of leg members.

Abstract: The invention concerns a protocol for remote launching of a software application and reserving network resources with quality of service between a caller terminal TA and a called terminal TB. Said protocol consists in: transmitting (A) from the caller terminal to the called terminal TB a reservation request for connection via a server and a transmission via an unconnected network and in establishing (B) between the caller terminal TA and the called terminal TB, a procedure for reserving network resources with quality of service by exchange of messages by transmission via the unconnected network. When the network resources reservation is accepted by the server, a connected network between the caller terminal and the called terminal is established (C) on the same physical network supporting the unconnected network via a control network RC.

Abstract: An invention related to an X-ray device for the generation of brief X-ray pulses comprising an X-ray tube having a thermionic cathode and an anode and an X-ray generator having a first circuit for the generation of a high-voltage pulse which is applied to the anode for the generation of the X-ray pulse. The X-ray generator further comprising a second circuit by which a low voltage is continuously applied to the anode which pre-heats the X-ray tube and is at most sufficient for the generation of low-energy X-radiation. The first circuit can have a high-voltage power supply unit which charges a high-voltage capacitor which can be applied to the anode via a high-voltage switch. The first circuit can be a Marx generator. There may be only one power supply, which both generates the continuously low voltage and also drives the Marx generator for the generation of the high voltage.

Abstract: A seating system is provided including a beam for supporting seats, wherein the seats are individually mounted to the beam at any selected longitudinal position along the beam. The system facilitates seat positioning and repositioning in a manner that optimizes seating adaptability and ease of installation. The beam preferably includes integral first and second track portions. The first track portion includes a channel that receives bracket-mounted connectors by which the beam is fixed relative to the ground. Each of the seats has at least one seat support with a clamp portion that secures to the second track portion of the beam, free from the channel to avoid interfering with the connectors, regardless of the point at which the support is clamped to the beam. The second track portion is preferably shaped to include a rear overhang and front overhang defining oppositely directed undercut surfaces on which the seat support is securely mounted.

Abstract: A gantry crane has first and second side support frames spaced by a pair of trolley beams. A load lifting mechanism is connected to the trolley beams and includes a lift frame for engaging a load to be lifted. An operator cab is mounted on the first side support frame and is vertically moveable between a lowermost position and an uppermost position in an operational plane defined by the first side support frame. A cab lift cable has a length and a first end fixed to the operator cab and a second end fixed to the side support frame. A hydraulic cylinder urges the cable between its fixed first and second ends in a direction transverse to a portion of its length. In another embodiment of the invention, an operator cab is adapted to be horizontally moveable. The elevating operator cab of the present invention can be configured to move horizontally. The elevating operator cab is lifted by a carriage beam vertically moveable along vertical legs of the first side support frame.

Abstract: An ad-hoc, peer-to-peer radio access system for cellular communications systems using time division duplex as a way of maximizing the bits/hz/km2 for cellular systems. The network architecture of the ad-hoc system allows the radio access to be integrated with the fixed components of a conventional cellular system, PSTN or ISP. The objective is to make the system of the invention transparent to the features and services provided by the external network. The advantages of such a system to a cellular operator are that significantly less infrastructure is required, and that the RF spectrum is more efficiently utilized resulting in much lower building and operating costs. The system architecture is comprised of remote terminals, routers, gateways, and at least one gateway controller that interfaces the ad-hoc system to a cellular network system. The ad-hoc system of the invention allows for both voice and data transmissions and receptions.

Abstract: A zoom lens is provided. The zoom lens includes a first lens group having a negative refractive power, a second lens group having a positive refractive power, and a third lens group having a negative refractive power. Here, the first through third lens groups are sequentially arranged from an object side toward an image side. At least the second lens group is moved along an optical axis to change magnification. The expression 3.7 < L T F W < 5.4 is satisfied, where LT denotes a distance on the optical axis from an object-side plane of the first lens group to an image plane at a wide-angle end, and FW denotes an overall focal length of the zoom lens at the wide-angle end. Accordingly, the zoom lens is miniaturized and minimizes a change in aberration due to high magnification.
