Abstract: Systems and methods are described for implanting a device in a mammalian eye to raise intraocular pressure. In some embodiments, the device (54) includes an arcuate body that, when implanted, obstructs aqueous humor outflow from the anterior chamber (38) of the eye.

Abstract: A microscopic translation device for a microelectromechanical system includes a pair of linear stator assemblies disposed in spaced relation to define an elongate channel. Each assembly is formed by a plurality of stators arranged in a row along the channel. A shuttle member is disposed between the stator assemblies for translating movement along the channel. The shuttle member includes a plurality of rotors extending outwardly from opposite sides. The shuttle is grounded through the stator assemblies and includes a mounting area for an object to be translated. Electrical lines are individually connected to alternate stators of a plurality of groups of the stators. A current supply sequentially supplies current through the electrical lines to the alternate stators so as to effect charging of the stators in a predetermined sequence. This produces a tangential capacitive force that causes translation of the shuttle.

Abstract: A dynamically reconfigurable optical add/drop multiplexer makes use of a single or a plurality of optical narrowband filters and a single or plurality of actuated optical devices to re-map the optical beams through the filter/s to drop and/or add a light of one wavelength. The input optical beam may be composed of a plurality of wavelengths. The beam as it impinges on the narrowband filter is reflected except for a single wavelength that passes through. The reflected beam can either be directed to couple the light to output ports or reflected to impinge on another filter to pass another wavelength and reflect the rest of the wavelengths. This can be repeated to drop a plurality of wavelengths individually. Adding a wavelength to the beam may be introduced at the filter where that specific wavelength is dropped to pass through the filter and join the reflected beam. This also is repeated for adding a plurality of wavelengths. This invention can be used to drop/add bands of wavelengths.

Abstract: A distributed gain optical fiber amplifier makes use of a single or a plurality of counter propagating pumping optical beams, and a plurality of short lengths of doped fibers that are distributed along an optical network. Pumping optical beams is introduced into the fiber by coupling single or a plurality of pumping laser sources that can be operating at the same wavelength using a wavelength division multiplexer coupler. As the pumping energy propagates through the short lengths of the doped fibers some portion of the pump energy is transferred into the signal, which is propagating along the same fiber, causing it to be amplified.

Abstract: An optical switch guides data transmitting light beams along free space switching paths from one or more input optical fibers to one or more output optical fibers. The optical switch includes a microchip base member, diffractive, refractive or reflective optical elements positioned on carrier panels, and actuators for moving the carrier panels. The optical elements are positionable by the actuators to guide light beams emitted by the input optical fibers in free space to the receiving output optical fibers. The actuators may be linear and/or rotary. Switching of light beams can be from one input port to one or many output ports, and vice versa, to form a free space optical cross-connect switch and router.
