    • One embodiment of the present invention is an array of nanoscale latches interconnected by a nanowire bus to form a latch array. Each nanoscale latch in the nanoscale-latch array serves as a nanoscale register, and is driven by a nanoscale control line. Primitive operations for the latch array can be defined as sequences of one or more inputs to one or more of the nanowire data bus and nanoscale control lines. In various latch-array embodiments of the present invention, information can be transferred from one nanoscale latch to another nanoscale latch in a controlled fashion, and sequences of information-transfer operations can be devised to implement arbitrary Boolean logic operations and operators, including NOT, AND, OR, XOR, NOR, NAND, and other such Boolean logic operators and operations, as well as input and output functions. Nanoscale-latch arrays can be combined and interconnected in an almost limitless number of different ways to construct arbitrarily complex, sequential, parallel, or both parallel and sequential computing engines that represent additional embodiments of the present invention.
    • 本发明的一个实施例是通过纳米线总线互连以形成锁存阵列的纳米级锁存器的阵列。 纳米尺度锁存阵列中的每个纳米级锁存器用作纳米尺度寄存器,并由纳米尺度控制线驱动。 锁存阵列的原始操作可以被定义为一个或多个输入到纳米线数据总线和纳米尺度控制线中的一个或多个的序列。 在本发明的各种锁存阵列实施例中,可以以受控的方式将信息从一个纳米级锁存器传送到另一个纳米级锁存器,并且可以设计信息传输操作的序列以实现任意的布尔逻辑运算,并且运算符包括NOT, AND,OR,XOR,NOR,NAND和其他这样的布尔逻辑运算符和操作,以及输入和输出功能。 纳秒级锁存器阵列可以以几乎无限数量的不同方式组合和互连,以构造代表本发明附加实施例的任意复杂,顺序,并行或并行和顺序的计算引擎。

    • A fluid-pressure-operated actuator is arranged to have three set positions and preferably a fail-safe characteristic in one of the three positions. In one embodiment an H-section piston moves in an actuator body and is set in its two extreme positions by fluid pressure introduced behind the web of the piston through one or other of spindles having heads and bores. To set the intermediate position, annular pistons can be moved along the spindles by pressure introduced at inlet pipes in the body until those pistons contact the heads of the spindles. The spindles are adjustable in the body to set the intermediate position of the piston and adjusting bolts set the extreme positions of the piston. For a fail-safe situation, a reservoir and control valve are introduced. As an alternative to annular pistons springs acting through top-hat shaped buffers can be used giving a fail-safe situation in the intermediate position of the piston.
    • 流体压力操作的致动器被布置成具有三个设定位置,并且优选地在三个位置之一中的故障安全特性。 在一个实施例中,H型活塞在致动器主体中移动,并且通过经由具有头部和孔的一个或另一个心轴引入到活塞腹板后面的流体压力而被设定在其两个极限位置。 为了设置中间位置,环形活塞可以通过在体内的入口管处引入的压力沿主轴移动,直到那些活塞接触心轴的头部。 主轴可在主体中调节以设定活塞的中间位置,调节螺栓设置活塞的极限位置。 对于故障安全的情况,引入了一个储存器和控制阀。 作为环形活塞的替代方案,可以使用通过顶帽形缓冲器作用的弹簧,从而在活塞的中间位置提供故障安全的情况。
