Abstract: A mezzanine connector assembly adapted to connecting a top PCB and a bottom PCB. The mezzanine connector assembly includes a floatable upper connector and a lower connector. The upper connector has an electrical connecting device and an optical connecting device. The electrical connecting device includes a conductor having a floatable upper end and a fixed lower end, the optical connecting device having an optical waveguide with one end connected to the upper PCB and a lower end fixed to the housing by a ferrule. The lower connector has a housing, a turning lens received in the housing, and an electrical contact connected to the bottom PCB for mating with the lower end of the conductor of the upper connector, the turning lens defining an upward opening to receive the ferrule of the upper connector, a forward opening for receiving an optical plug.

Abstract: A high precision micro/nanoscale machining system. A multi-axis movement machine provides relative movement along multiple axes between a workpiece and a tool holder. A cutting tool is disposed on a flexible cantilever held by the tool holder, the tool holder being movable to provide at least two of the axes to set the angle and distance of the cutting tool relative to the workpiece. A feedback control system uses measurement of deflection of the cantilever during cutting to maintain a desired cantilever deflection and hence a desired load on the cutting tool.
