摘要： The present system for redirecting a light beam makes use of a transparent pressure vessel that is filled with a compressible fluid, whose refractive index changes as a function of the pressure applied to the compressible fluid to redirect the path of a light beam that is transmitted through the transparent pressure vessel. An incident beam of coherent monochromatic light is applied to a transparent segment of a wall of the transparent pressure vessel, where this incident light beam is refracted by the compressible fluid contained in the transparent pressure vessel. The refracted light beam traverses the transparent pressure vessel and exits the transparent pressure vessel at a point along the opposite wall of the transparent pressure vessel as determined by the refractive index of the compressible fluid, which is determined by the pressure of the compressible fluid. The pressure of the compressible fluid is controlled by using a pump that is fluidically connected to the transparent pressure vessel. By varying the pressure of the compressible fluid and thus its refractive index, the exit point of the refracted light beam on the wall of the transparent pressure vessel can be precisely controlled. The incident light beam can therefore be switched among a plurality of light sensing or optically transmissive elements that are arrayed in a linear array along the wall of the transparent pressure vessel by simply regulating the pressure applied to the compressible fluid.

摘要： An asynchronous, fiber optic, ring network includes a number of nodes where data enters and exits the network. Each of these nodes has its own clock to provide timing needed by equipment at that node. So that synchronous data can be transmitted between predetermined nodes, a master node provides timing information which may be used at any node to synchronize its clock. Timing information comprises the propagation delay around the ring (ring latency) as measured by the master node. This measure of propagation delay is transmitted by the master node as an information packet available at all nodes. Synchronization of any other node with the master requires that the other node perform its own measurement of propagation delay, compare its measurement with that of the master node, and make adjustments to its own clock that tend to decrease the difference between these measurements.
