  • Fiber optic power control systems and methods
    Patent number: 6681073
    Abstract: Control systems and methods are provided for controlling optical energy transmitted through a fiber optic. The systems and methods employ a digital controller circuit coupled to at least one sensor for receiving a sensed level stimulus output therefrom, and coupled to a fiber optic power control device for providing a digitized feedback signal thereto. The digital controller circuit, which can operate in one of a plurality of modes and automatically switch between modes, can include one or more of a digital filter, memory for storing control programs and data, an analog-to-digital converter for converting received sensed level stimulus to a digital signal, a digital communication interface, and a processor for software processing of the digital signal. Automatically powering up or resetting the digital power control system is also provided.
    Type: Grant
    Filed: March 19, 2001
    Date of Patent: January 20, 2004
    Assignee: Molecular OptoElectronics Corporation
    Inventors: Kwok Pong Chan, Robert Filkins, David Gilles Gascoyne, Richard Alan Hogle, Kevin J. Shaughnessy, Robert Christian Tatar
