摘要： A fluidic structure includes a channel and along the channel is a series of sensing components to obtain information about objects traveling within the channel, such as droplets or other objects carried by fluid. At least one sensing component includes a set of cells of a photosensor array. The set of cells photosense a range of photon energies that emanate from objects, and include a subset of cells that photosense within subranges. A processor can receive information about objects from the sensing components and use it to obtain spectral information. The processor can perform an initial analysis using information from one set of sensing components and, based on the results, control a fluidic device in the channel, such as a gate, to retain objects, such as for concentration and more detailed analysis by other sensing components, or to purge objects from the channel.

摘要： A display apparatus includes a luminescent screen having pixels formed from blue, green and red luminescent material that are selectively activated by a laser beam to generate a full color image. The display utilizes a closed loop laser scanning/modulating arrangement in which a Position Sensitive Device (PSD) located next to the screen is used to determine the location of the impinging beam, and to transmit timing/location data to the laser addressing system. The laser addressing system uses the timing/location data to adjust and/or modulate the laser beam, thereby generating high-energy beam pulses that activate the selected pixels. The PSD includes vertical strips located along the side edges of the screen, or a sheet that is located behind the screen and accessed, for example, by way of slits or apertures formed in the screen material. The PSD sheet is coupled to an optional power source to form a photon-multiplication device.

摘要： A locally-outcoupled optical resonator has whispering gallery modes existing in a nearly circular resonator. Light is outcoupled by providing a local perturbing feature on the perimeter of the locally-outcoupled cavity resonator. The perturbing feature provides an outcoupling or loss mechanism that asymmetrically interacts with circulating whispering gallery modes, thereby making the resonator capable of uni-directional output.

摘要： A method of converting selected areas of a semiconductor structure into a disordered alloy comprising a well feature epitaxially deposited on a semiconductor support, the well feature comprising at least one first well layer of narrow bandgap material deposited adjacent to at least a second layer of wider bandgap material or interposed between second and third layers of wider bandgap material. The disordered alloy exhibits higher bandgap and lower refractive index properties than the first layer. The method comprises the steps of (1) either placing the structure within a protective environment to prevent the escape of volatile components from the structure during subsequent processing or alternatively, covering the structure with a protective coating to prevent the escape of any elemental component of the structure, (2) heating the structure to a background temperature .[.just.]. below the temperature required to achieve rapid thermal disordering of the well feature, (3) scanning the structure with a laser beam while maintaining the applied heat to selectively disorder the well feature due to the additional heat supplied by the laser beam forming a pattern of wider bandgap and lower refractive index properties prescribed in the feature by the scanning trace of the laser beam compared to areas of the feature not scanned by the laser beam. The well feature may be a quantum well structure comprising a single quantum well structure, a multiple quantum well structure or a separate confinement single quantum well or a separate confinement multiple quantum well or a heterostructure including an active region being the first layer.

摘要： A structure and method for producing same provides a solid-state light emitting device with suppressed lattice defects in epitaxially formed nitride layers over a non-c-plane oriented (e.g., semi-polar) template or substrate. A dielectric layer with “window” openings or trenches provides significant suppression of all diagonally running defects during growth. Posts of appropriate height and spacing may further provide suppression of vertically running defects. A layer including gallium nitride is formed over the dielectric layer, and polished to provide a planar growth surface with desired roughness. A tri-layer indium gallium nitride active region is employed. For laser diode embodiments, a relatively thick aluminum gallium nitride cladding layer is provided over the gallium nitride layer.

摘要： Sensors can be used to obtain encoded sensing results from objects that have nonuniform relative motion. A photosensor or impedance-based sensor, for example, can obtain sensing results from objects that have relative motion within a sensing region relative to the sensor, with the relative motion being, for example, periodically varying, randomly varying, chirp-varying, or modulated relative motion that completes at least one modulation cycle within the sensing region. Relative motion can be caused by varying objects' speed and/or direction or by controlling flow of fluid carrying objects, movement of a channel, movement of a support structure, movement of a sensor, and/or pattern movement. A fluidic implementation can include shaped channel wall parts and/or a displacement component causing time-varying lateral displacement. A support structure implementation can include a scanner device and a rotary device that respectively control scanning and rotating movement of a movable support structure or of a sensor.
