    • A design is presented for an NxN crossbar switch. A crossbar switch is one of the basic components of Optical Switching Networks. An optical NxN switch has the capability of connecting any light beam from the input of the switch to any output port of the switch without interfering with other light beams. That is each single input is connected to one and only one of the output ports without interfering with any other beam or beams. The design presented is based on the use of precision meso-sale mechanics of the size typically found in miniature disc drives and meso-scale optical components. This meso-scale mechanics is then controlled or driven by precision servo-electronics and software to achieve the correct switching. The precision servomechanisms, meso-scale mechanics, electronics and software control are designed to work together to self-compensate for assembly or manufacturing defects and deleterious environmental, including temperature, effects.
    • 为NxN交叉开关提供了一个设计。 交叉开关是光交换网络的基本组件之一。 光学NxN开关具有将来自开关输入的任何光束连接到开关的任何输出端口的能力,而不会干扰其他光束。 这是每个单个输入连接到一个且仅一个输出端口,而不会干扰任何其他波束或波束。 所提出的设计是基于使用通常在微型光盘驱动器和中尺度光学部件中发现的尺寸的精密中间销售机制。 然后通过精密伺服电子和软件来控制或驱动该中尺度力学,以实现正确的切换。 精密伺服机构,中尺度力学,电子和软件控制被设计为一起共同补偿组装或制造缺陷和有害环境,包括温度,影响。

    • Systems and techniques are described for distributed control and coordination of autonomous agents in a system. A protocol for distributed control allows autonomous agents to negotiate a group task for the agents, such as locomotion or self-reconfiguration in a robot application, and to synchronize individual agent actions to effect the group task. A protocol for adaptive communication allows autonomous agents, such as physically coupled self-sufficient robot modules, to continuously discover changes in their local topology. In general, in one implementation, the technique includes: discovering a local topology, which includes a type of a communication connection to autonomous agents in the reconfigurable network topology, and determining an action based upon a received control message and the determined local topology.

    • In a frequency translator for r-f television signals and the like there is provided an input frequency selective matching network to pass only r-f television signals in a predetermined range of about 50 to 300 MHz (vhf), a novel combination oscillator, impedance matching network, and mixer arranged for mixing incoming television signals from a cable or antenna with a preselected reference signal of a constant frequency generated by the oscillator to produce output signals from the mixer in a higher band of frequencies of about 500 to 750 MHz (uhf). An output frequency selective matching network passes only signals in said second band of frequencies to an output terminal. The impedance matching network provides a conjugate match for the output impedance of the oscillator and the input impedance of the mixer so as to inhibit the reflection of undesirable signal products from the mixer back to the oscillator and minimize power loss. The output frequency selective network and mixer arrangement do not require an active gain stage and an associated additional frequency selective matching networks in an input circuit ahead of the mixer.
    • 在用于rf电视信号等的频率转换器中,提供输入频率选择匹配网络,以仅在大约50至300MHz(vhf)的预定范围内通过rf电视信号,新颖的组合振荡器,阻抗匹配网络和 混频器布置成用于将来自电缆或天线的输入电视信号与由振荡器产生的恒定频率的预选参考信号进行混合,以在约500至750MHz(uhf)的较高频带内从混频器产生输出信号。 输出频率选择匹配网络仅将所述第二频带中的信号传送到输出端。 阻抗匹配网络为振荡器的输出阻抗和混频器的输入阻抗提供共轭匹配,以便抑制不期望的信号产物从混频器反射回振荡器并使功率损耗最小化。 输出频率选择网络和混频器装置在混频器之前的输入电路中不需要有源增益级和相关联的附加频率选择匹配网络。
