20080197272 | Sensing Photons From Object In Channels - 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. | 08-21-2008 |
20090016672 | Producing Fluidic Waveguides - Fluidic waveguides have inward surfaces or areas that face each other, separated by a channel region that can be covered. For example, an integrally formed channel component can include two walls parts and a connecting part, with inward surfaces on the wall parts and, extending between them, a base surface; a covering component's lower surface can also extend between the inward surfaces, bounding the channel region; other fluidic, electrical, and optical components can also be attached. In a stack, the covering component can cover the first channel component, and the lower base surface of each preceding channel component can cover the following channel component. An integrally formed body of light-transmissive material can have a surface that includes a waveguide's inward areas and a base area between them; a covering component can be mounted on areas adjacent the inward areas, providing an enclosed channel region. | 01-15-2009 |
20090016690 | Producing Sandwich Waveguides - Complementary surface fabrication processes such as molding, casting, embossing, and so forth, are used to produce articles, structures, or components structured to operate as sandwich waveguides. Resulting complementary surface artifacts include, for example, optical quality surfaces on wall parts, other exposed artifacts that occur where a complementary solid surface contacts non-solid material during fabrication, and sub-surface artifacts such as integrally formed connections between wall parts and base parts. A body whose surface includes a waveguide's inward surfaces, outward surfaces, and light interface surfaces to receive incident light can be formed in a single step, leaving a partially bounded fluidic region that can then be covered to provide a channel that is bounded along a length yet open at its ends; other fluidic, electrical, and optical components can also be attached. | 01-15-2009 |
20090042333 | Structure and Method for Surfaced-Passivated Zinc-Oxide - A semiconductor device has a heterostructure including a first layer of semiconductor oxide material. A second layer of semiconductor oxide material is formed on the first layer of semiconductor oxide material such that a two dimensional electron gas builds up at an interface between the first and second materials. A passivation layer on the outer surface stabilizes the structure. The device also has a source contact and a drain contact. | 02-12-2009 |

20100291757 | METHOD OF FORMING, MODIFYING, OR REPAIRING A SEMICONDUCTOR DEVICE USING FIELD-CONTROLLED DIFFUSION - A technique for altering or repairing the operating state of a semiconductor device comprises field-controlled diffusion of mobile dopant atoms within the metal oxide crystal lattice. When heated (e.g., above 550 K) in the presence of an electric field (e.g., bias to ground of +/−50 V) the dopant atoms are caused to collect to form an ohmic contact, leaving a depletion region. Metal-semiconductor junction devices such as diodes, photo-diodes, photo-detectors, MESFETs, etc. may thereby be fabricated, repaired or modified. | 11-18-2010 |
20110082353 | Implanting Optical Cavity Structures - An implantable product includes an optical cavity structure with first and second parts, each of which can operate as an optical cavity. The first part includes a container with at least one opening through which bodily fluid can transfer between the container's interior and exterior when the product is implanted in a body. The second part includes a container that is closed and contains a reference fluid. The implantable product can also include one or both of a light source component and a photosensing component. Photosensed quantities from the first part's output light can be adjusted based on photosensed quantities from the second part's output light. Both parts can have their light interface surfaces aligned so that they both receive input light from a light source component and both provide output light to a photosensing component. | 04-07-2011 |
20130240706 | Transmitting Light with Lateral Variation - Input light, such as from an optical sensor or stimulus-wavelength converter, includes one or more light or dark sub-bands. The input light is transmitted, such as through a transmissive layer or transmission component, to obtain effects due to transmission with lateral variation. A detector can, for example, obtain spectral information or other photon energy information about the sub-bands due to lateral variation. For each light or dark sub-band, a transmission component can, for example, provide a respective light or dark spot, and spot position can be used to obtain spectral information such as absolute wavelength or wavelength change. A photosensing component can sense or detect transmitted light or output photons, such as with a photosensor array or a position-sensitive detector. Circuitry can use photosensed quantities to obtain, e.g. a differential signal or information about time of wavelength change. | 09-19-2013 |
20140370612 | Method and System Implementing Spatially Modulated Excitation or Emission for Particle Characterization with Enhanced Sensitivity - A method and system for using spatially modulated excitation/emission and relative movement between a particle (cell, molecule, aerosol, . . . ) and an excitation/emission pattern are provided. In at least one form, an interference pattern of the excitation light with submicron periodicity perpendicular to the particle flow is used. As the particle moves along the pattern, emission is modulated according to the speed of the particle and the periodicity of the stripe pattern. A single detector, which records the emission over a couple of stripes, can be used. The signal is recorded with a fast detector read-out in order to capture the “blinking” of the particles while they are moving through the excitation pattern. This concept enables light detection with high signal-to-noise ratio and high spatial resolution without the need of expensive and bulky optics. | 12-18-2014 |

20100040981 | Tuning Optical Cavities - A tunable optical cavity can be tuned by relative movement between two reflection surfaces, such as by deforming elastomer spacers connected between mirrors or other light-reflective components that include the reflection surfaces. The optical cavity structure includes an analyte region in its light-transmissive region, and presence of analyte in the analyte region affects output light when the optical cavity is tuned to a set of positions. Electrodes that cause deformation of the spacers can also be used to capacitively sense the distance between them. Control circuitry that provides tuning signals can cause continuous movement across a range of positions, allowing continuous photosensing of analyte-affected output light by a detector. | 02-18-2010 |
