  • System and method for a compact optical receiver with wide dynamic range
    Patent number: 7394995
    Abstract: An optical receiver is disclosed comprising an erbium-doped fiber amplifier (EDFA) that is coupled to a photodiode and transimpedance amplifier without filtering output light signal in the EDFA. Optionally, a clock/data regenerator can be coupled to the electrical output of the transimpedance amplifier for compensating for noise distortion and timing jitter for affecting the control loop feeding back for adjusting the electrical current into a pump laser of an optical pre-amplifier. Furthermore, the optical receiver of the present invention can also be implemented in a transponder.

  • Apparatus and method for inductive heating a workpiece using an interposed thermal insulating layer
    Publication number: 20080136066
    Abstract: Disclosed herein is an apparatus and method with inductive heating of an electrically conductive workpiece such as a barrel used in molding or extrusion, having a layer of thermal insulation interposed between the induction windings and the workpiece, and using alternating current (AC) at an elevated frequency. Further, variable pitch induction windings may be used to generate a non-uniform and calculated heat input profile, such as to compliment the configuration of a screw for transporting material through the barrel.
