  • SERS analyzer
    Patent number: 7502106
    Abstract: A surface enhanced Raman scatter (SERS) analyte analyzer. The analyzer has floating surfaces for enhancement of the Raman scattered light from sample molecules. An injector may provide a spray of charged nanoparticles suspended in droplets of an evaporable solution into a chamber. When the solution quickly evaporates, droplets of nanoparticles are left without a supporting solution. These droplets or cloud of charged nanoparticles may then explode into a dispersion or aerosol. The charged nanoparticles may attract molecules of a sample for attachment to their surfaces. A laser light may impinge the attached molecules which may result in surface enhanced Raman scattered light received by a detector or a light spectrometer. Wavelength signatures may then be obtained from the spectrometer. The signatures may provide information about the molecules.

  • SPECTROSCOPIC SYSTEM
    Publication number: 20090040516
    Abstract: A spectroscopic system having a coded aperture as a gating device. Light of a Raman scattering may enter the system and encounter a mask gate. The mask may have a matrix of micro mirrors some of which pass light on to a diffraction grating when the gate is on. Some of the mirrors will not pass on light thereby resulting in coded light to the grating. If the gate is off, then no light is passed on to the grating. The grating may pass the coded and spectrally spread light on to a detector array. The array signals representing the light on the array may go to a processor so one can obtain information about the target that emanated the Raman scatter when impinged by a light beam.

  • OPTICAL CAVITY SYSTEM HAVING AN ORTHOGONAL INPUT
    Publication number: 20090014670
    Abstract: An optical system having a closed loop light path with a source for providing light in a direction parallel to the normal of an input to the light path. The light may be provided via a diffracting mechanism to the input. The system may be a cavity ring-down sensor or some other optical device. The light path may be formed in a laser gyroscope type cavity. A light source may have a beam aligned to a spot, indicator or mark near the input of the cavity. The location of the spot, indicator or mark may be determined in accordance with parameters of the diffracting mechanism and/or cavity. A fixture for holding the light source may be secured so that placement of the source in the fixture will automatically result in an aligned light source. Then the diffracting mechanism may be inserted to further complete fabrication of the optical system.

  • Mode selective semiconductor mirror for vertical cavity surface emitting lasers
    Patent number: 7391799
    Abstract: A vertical cavity surface emitting laser with a mode-selective mirror. A filter is formed on the top DBR stack of a VCSEL. The filter includes semiconductor layers that are etch stops for immediately superior layers. The filter is selectively etched to create a first region that is phase matched to the top DBR stack and a second region that is phase mismatched to the top DBR stack. The second region inhibits undesired modes and provides additional absorption for the undesired modes. The first region is formed using a wet-etch process whose etch depth is controlled because the semiconductor layers are etch stops for immediately superior layers.

  • CYTOMETER HAVING FLUID CORE STREAM POSITION CONTROL
    Publication number: 20080124805
    Abstract: A cytometer having two or more chambers or regions in a containment structure of sheathing fluid that may be used to provide hydrodynamic focusing of another fluid having particles to be observed. The latter fluid may be a core stream which may have its lateral position in a flow or measurement channel affected by control of at least one of the parameters of the several segments of the sheathing fluid. The lateral position of the core stream may be aligned with a light source and detector for a count and observation of the particles. Electrical signals from the detector may be fed back to a processor which may control one or more parameters of the sheathing fluid in the various chambers or regions via pumps, valves, and flow and pressure sensors. This control of parameters may provide for the positioning of the core stream. This cytometer may be miniaturized.

  • Cardiac disease treatment and device
    Patent number: 7326174
    Abstract: A device for treating cardiac disease of a heart having an upper portion and a lower portion divided by an A-V groove, the device including a jacket adapted to be secured to the heart, and a non-adherent material in association with the jacket. The jacket is fabricated from a flexible material defining a volume between an upper and a lower end, the jacket being adapted to be adjusted on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain expansion of the heart beyond the maximum adjusted volume during diastole and permit substantially unimpeded contraction of the heart during systole. As a result of the flexible material, the jacket allows unimpeded diastolic filling of the heart.
