Abstract
Systems are provided for an optical device. The optical device comprises a lens actuation system including a motor, a flywheel, a connecting linkage, a plurality of articulating arms, and a lens. The lens is housed in a frame coupled to the articulating arms and driven via the lens actuation system between an upstream position and a downstream position.
Claims20
A lens actuation system, comprising:
- a motor rotationally coupled to a flywheel via a shaft;
- a rod coupled at a first end to the flywheel and at a second end opposite the first end to a connecting linkage, wherein the first end is off-center of the flywheel and the second end is off-center of the connecting linkage;
- and
- a plurality of articulating arms coupling the connecting linkage with a frame housing a lens.

An optical device, comprising:
- a light emitting diode (LED) element;
- a lens positioned at a distance away from the LED element;
- a lens actuation system including a motor adapted to drive movement of a flywheel, a connecting linkage, and a plurality of articulating arms to adjust the distance;
- and
- a sensor adapted to measure a position of the flywheel.
2 more elements
A method for operating a lens actuation system, comprising:
- generating output light from a light emitting diode (LED) element;
- moving a lens receiving the output light linearly back and forth via the lens actuation system by rotating a motor in a single direction, the lens actuation system having a connecting linkage;
- and
- sensing the movement or rotation via a sensor.
