  • Separable locking fiber optic connector
    Patent number: 9417407
    Abstract: A fiber optic connector includes a housing and a locking member. The housing has a longitudinal passage extending between a first opening at a first end of the housing and a second opening at a second end of the housing, the housing sized to fit within a fiber optic receptacle. The locking member is a separate part from the housing and is sized to fit within a retaining notch in the fiber optic receptacle. The locking member, when secured to the housing and located in the retaining notch, interfaces with the retaining notch to prevent separation of the housing from the receptacle.

  • Advanced-process-control system utilizing a lambda tuner
    Patent number: 7809459
    Abstract: An advanced process control (APC) system. The APC system comprises a database for receiving process data from a measurement tool for a plurality of process runs and for storing the process data. A lambda tuner determines a tuned-lambda value corresponding to a process-capability-index value based on upper and lower process control limits and statistics derived from the process data. A process-run controller updates a recipe value based on the received process data and the tuned-lambda value.
