摘要： Bubble stability within an optical switch is enhanced by controlling the expansion or movement of a bubble from a liquid-containing trench into available adjacent spacing. Typically, the adjacent spacing is formed between an optical waveguide substrate and a heater substrate, where the heater substrate includes a microheater for forming the bubble. The bubble enhancement is provided by intentionally altering surface features along at least one of the substrates.

摘要： An imager captures light reflecting off an object of interest and generates two or more images of the object. A controller identifies artifacts in one of the captured images and defines one or more non-interpretation regions in a binary image. The non-interpretation regions include pixels representative of the artifacts and do not include pixels representative of the object of interest. The controller performs pixel operations on the pixels in the binary image to reduce a number of artifacts in a final image.

摘要： Each opto-mechanical pointing device includes a housing having a base that two or more rollers extend beyond to make contact with a surface. An optical module that includes a light source and a detector track the motion of the opto-mechanical pointing device directly or indirectly. Light reflecting off markings positioned opposite of each detector is used to determine the speed and distance traveled by an opto-electrical pointing device. Alternatively, the speed and distance traveled by an opto-electrical pointing device is determined by monitoring the tilt or rotation of the opto-mechanical pointing device with respect to the surface beneath the pointing device.

摘要： A system and method for tracking the x, y and z coordinates of a position of an input device in an interactive computer system is disclosed. An image sensor situated on the input device captures images of an electronic marker displayed on a display screen. As the position of the input device changes, the features of the electronic marker as captured by the image sensor also change. Images of the electronic marker captured during game play are compared to a calibration image of the electronic marker to determine current x, y and z coordinates of positions of the input device. The game display is updated to reflect the movements of the input device.

摘要： An optical imaging system and method for achieving a large depth of field without decreasing the relative aperture of an imaging lens. The imaging system has a light source for sequentially illuminating an object to be imaged with light of different ones of a plurality of wavelengths, and an imaging lens that has a focal length that varies with the wavelength of the light that illuminates the object. For each wavelength of light by which the object is illuminated, the imaging lens will image a different object plane onto an image receiving unit, and the image receiving unit will capture one well-focused, high resolution image of the object.

摘要： An optical switching apparatus and a method of efficiently switching optical signals are disclosed. Optical insertion loss may be reduced in a planar lightwave circuit by determining an optimal spacing between perturbations including using passive perturbations, having a three dimensional refractive index distribution, in an array of waveguides, or by adjusting parameters of existing perturbations e.g. their spacing. The perturbation and each waveguide have different three dimensional refractive index distributions. The perturbation may be positioned anywhere in the array of waveguides. The perturbation may be a trench, a region of refractive index different from that in each waveguide, a broken waveguide core, or a modification of the topography of the array of waveguides. In one embodiment, the perturbation is a periodic or quasiperiodic perturbation.
