Abstract: A method for real-time disparity estimation of stereo video data receives sequence of frames of stereo video data. Image-based disparity estimation is initially conducted to produce initial disparity estimates, and the disparity estimates are refined in a space-time volume. The algorithm produces disparity via multi-thread process in which an output is independent of the input for each step of the process.

Abstract: A method for disparity estimation of stereo video data receives a sequence of frames of stereo video data. Image-based disparity estimation is initially conducted on a frame-by-frame basis to produce initial disparity estimates. A plurality of initial disparity estimates is grouped into a space-time volume. Disparity error is reduced in the space-time volume to refine the initial disparity estimates.

Abstract: A monolithic waveguide/MEMS switch is disclosed that has a waveguide portion and a MEMS mirror portion fabricated on a single substrate, such as a as a silicon-on-insulator wafer. The monolithic waveguide/MEMS switch adjusts the phase of an optical signal by varying the position of one or more moveable mirrors. The mirror portion includes a mirror having a reflective surface that is attached to at least one MEMS actuator to achieve in-plane motion of the mirror (moves parallel to a plane of said at least one waveguide). In one implementation, the MEMS actuator is embodied as a known comb drive actuator. The phase adjustment techniques of the present invention may be employed in various optical devices, including wavelength selective optical switches that support multiple optical channels.

Abstract: A method of controlling fluid flow (14) in a boundary layer at a fluid-surface interface comprising, providing a plurality of blades (11) which project from the fluid contracting surface into a boundary layer such that in use the blades (11) are orientated to control fluid flow (14) in the boundary layer.

Abstract: A portable waveguide sensor having one or more gratings. In one embodiment, the sensor has a waveguide, wherein a plurality of grooves imprinted onto the waveguide form a Bragg grating. The surface of the grooves has a functional layer adapted to bind a substance of interest, e.g., a biological pathogen. When the pathogen binds to the functional layer, the binding shifts the spectral reflection band corresponding to the Bragg grating such that a probe light previously reflected by the grating now passes through the grating, thereby indicating the presence of the pathogen. In another embodiment, the sensor has a Mach-Zehnder interferometer (MZI), one arm of which has a resonator formed by two Bragg gratings. The surface of the resonator between the gratings has a functional layer whereas the Bragg gratings themselves do not have such a layer.
