  • Patent number: 7116855
    Abstract: An optical shuttle system for routing signals in a communications system that includes a terminal connected to a power source, a shuttle that includes waveguides used for routing the signals, and a beam connected to the terminal and the shuttle so that the beam suspends the shuttle. When power from the power source is applied to the terminal, the beam drives a movement of the shuttle. Furthermore, a method of using an optical shuttle system for routing signals in a communications system, the method includes connecting a terminal to a power source, connecting a shuttle to a beam to suspend the shuttle, and applying power from the power source to the terminal so that the beam drives a movement of the shuttle in a direction substantially perpendicular to a direction of the beam.

  • Patent number: 7070699
    Abstract: A bistable microelectromechanical system (MEMS) based system comprises a micromachined beam having a first stable state, in which the beam is substantially stress-free and has a specified non-linear shape, and a second stable state. The curved shape may comprises a simple curve or a compound curve. In embodiments, the boundary conditions for the beam are fixed boundary conditions, bearing boundary conditions, spring boundary conditions, or a combination thereof. The system may further comprise an actuator arranged to move the beam between the first and second stable states and a movable element that is moved between a first position and a second position in accordance with the movement of the beam between the first and second stable states. The actuator may comprise one of a thermal actuator, an electrostatic actuator, a piezoelectric actuator and a magnetic actuator. The actuator may further comprise a thermal impact actuator or a zippering electrostatic actuator.
