摘要： A method and apparatus are disclosed for an optical fiber cross-connect switch incorporating an absolute position encoder and a magnetic actuation system into its alignment system. The switch comprises two optically opposed arrays of fiber-optic switching units, each of which contains a single fiber active to send or receive an optical communication signal. The magnetic actuation system comprising four magnetically polarizable actuator branches positioned surrounding the fiber and a magnetizable disk circumferentially attached to the fiber end. Selective magnetic polarization of the actuator branches bends the fiber end. A two-dimensional Moiré type position encoder determines the absolute position of the fiber end. The encoder comprises at east one plurality of radiation sources, which emits pulses of radiation (control signals) directed toward the switching units. Each switching unit is equipped with a reticle, an optical system that focuses the control signals onto the reticle, and a single photodetector, which measures the power of the control signals transmitted through the reticle. A controller uses the measured control signals to determine the two-dimensional position of the fiber in that switching unit and to generate actuation signals, which form the input for the actuation system.

摘要： A continuous inkjet print head jets a plurality of fluid streams from an array of multiple nozzle channels. The print head includes a flow conditioning means that establishes fully developed flow in one or more regions of the print head such that substantially equal flow conditions are created at each of the inlets of the multiple nozzle channels. The substantially equal flow conditions reduce nozzle-to-nozzle variations with respect to the required trajectories of the jetted fluids to improve jet pointing and thus lead to better print quality.

摘要： A method and apparatus are disclosed for a two-dimensional Moiré type absolute position encoder and an associated control system. A reticle having a pattern variation in two orthogonal directions is illuminated with radiation from a source which is structured so as to create a two dimensional Moiré interference at the reticle. Radiation pulses from the radiation source are multiplexed in time and the resulting interference fringes are converted into electronic signals using a detector. A controller uses the electrical signals to determine the absolute position of the reticle in two dimensions to within the area of a particular cell. After determining the particular cell location, the controller also employs the signals from the groups of radiation stripes to calculate an accurate position of the reticle within the cell.
