摘要： An absolute pressure regulator valve assembly for controlling the absolute pressure (P.sub.C) of a fluid source. The absolute pressure regulator valve assembly includes a hollow housing having an inlet port and a discharge port. The inlet port is in fluid communication with the fluid source. The discharge port is associated with a valve seat. A bellows assembly is positioned within the housing. The bellows assembly has an open first end and a closed second end. The first end is gas-tight sealed to the housing and is in fluid communication with a means for providing a reference pressure (P.sub.R) within the bellows assembly. A valve closure element is attached to the closed end of the bellows assembly. The valve closure element is positioned relative to the valve seat wherein motion of the bellows assembly provides opening and closure of the discharge port. A force biasing assembly is attached to the housing for imposing a force on the closed end to provide a desired adjustment of the pressure at the inlet port. During operation, when a net force on the closed end in the direction of the valve seat is greater than a net force in an opposite direction caused by a decrease of pressure at the inlet port, the valve closure element moves in a direction towards the valve seat.

摘要： Gimbal comprised of four concentric cylindrical shells rotatively attached to each other by three pairs of bearings or flexures. The innermost shell is rigidly attached to a suspended instrument. The outermost shell is attached to a vehicle. Each of the three pairs of bearings are colinear and define three axes of rotation which intersect at a point. None of the three axes are coincidental with a line of sight emanating from the instrument, and two of them are nonorthogonal. The gimbal provides the instrument with freedom of rotation about any axis relative to the vehicle, including about the instrument's line of sight, without the line of sight being vignetted by a bearing or any other gimbal structure. The respective angles between the three axes of rotation are set to minimize the exposure of the gimbal to gimbal lock, as well as to minimize the onset of secondary disturbances that occur when gimbal lock is approached.
摘要翻译：万向节包括四个同心圆柱形壳体，它们通过三对轴承或挠曲件彼此旋转连接。最内层的壳体刚性地连接到悬挂的仪器上。最外层的外壳附着在车辆上。三对轴承中的每一个都是共线的，并且限定了在一个点处相交的三个旋转轴。三轴都不符合从仪器发出的视线，其中两个轴是非正交的。万向架为仪器提供相对于车辆的任何轴线的旋转自由度，包括围绕仪器的视线，而没有视线被轴承或任何其他万向节结构所遮挡。设置三个旋转轴之间的相应角度，以使得万向架对万向节锁定的暴露最小化，以及使接近万向节锁定时发生的次级扰动的最小化。

摘要： A sighting apparatus is provided for aiming an optical device mounted on a moving platform and having both coarse and fine adjustment. The sighting apparatus includes a fixed base and an outer support ring that is capable of rotation by a drive motor about an azimuthal axis perpendicular to an axis defined by the outer support ring. A support hub is rotatably supported within the outer support ring and is capable of rotation by a drive motor about an elevational axis substantially coincident with the axis defined by the outer support ring. At least one mounting plate is supported by the support hub and the mounting plate is capable of movement about the azimuthal and elevational axes relative to the support hub, and the mounting plate is capable of movement about a roll axis perpendicular to the azimuthal and the elevational axes. The mounting plate is driven about the azimuthal and the elevational axes relative to the support hub by a two axis electromagnetic actuator attached to the mounting plate and the support hub.
