20090002790 | System and method for manipulating and processing materials using holographic optical trapping - An apparatus for manipulating particles (micro, nano, and pico) having one or more characteristics with an optical trap formed by modulating a laser beam with a Diffractive Optical Element (DOE). At least one characteristic of the material is selected; and a laser beam having a selected wavelength corresponding to the at least one selected characteristic of the material is generated. Values of the DOE are calculated corresponding to the at least one selected characteristic of the material. The beam and the DOE are modulated to produce a holographic optical trap having properties corresponding to the at least one selected characteristic; the trap is focused to a beam focus or selected spot size; and the beam focus is located near a particle location for trapping the particle therein. | 01-01-2009 |

20110091932 | Automated extraction and purification of samples using optical tweezers - An apparatus and method for purifying a forensic sample using an automated extraction and purification system includes optical tweezers; an input channel through which the sample is introduced; a chamber which receives the sample from the input channel; a collection channel through which selected particles of the sample are removed; and an output through which unselected particles of the sample are removed. At least one buffer input channel is provided. The input channel may allow sedimentation of the sample into the chamber by gravity. In another arrangement, the system includes an optical trapping system; a first channel through which the sample is introduced; a second channel through which buffer is introduced; wherein the optical tweezers are used to move selected particles of the sample from the first channel to the second channel. The selected particles may be sperm. The optical tweezers preferably utilize holographic optical trapping. | 04-21-2011 |

20120110851 | Systems and methods for preparing dental restorations - Improved systems and methods for producing dental restorations and ceramic materials for such restorations are disclosed. Optical properties, preferably including color and translucence characteristics, of a tooth or teeth of a patient are measured with a shade measuring instrument. The tooth to be restored is prepared, and a physical or virtual dental impression is created. A prescription for the restoration, which typically includes color, translucence and thickness information, is sent to the restoration fabrication facility either electronically or physically. A recipe and/or a mixture of ceramics are generated for the restoration, with multiple layers being specified, based on the measured optical properties. The recipe algorithm may adapt, or process checks may be performed, based on measurements of fabricated layers. Preferably, dental ceramics are specified to bracket the region of color space relevant to human teeth, and a reduced set of ceramic materials are manufactured and distributed. Based on measured optical characteristics of the ceramic materials, recipes and/or material mixtures are specified or prepared for the restoration. A virtual impression data file may be transmitted to the laboratory instead of a physical impression. | 05-10-2012 |

20080202024 | Porous And Non-Porous Particle Reinforcement For Viscous Hydraulic Matrices - A hydraulically-applied mulch matrix comprising non-porous particles, porous particles and mixtures thereof combined with a mechanically and or chemically bonded fiber mulch mixed within a high viscosity slurry to keep the particles in suspension for dispersion onto soil surfaces with mulch spraying equipment for enhanced erosion control and higher level plant establishment. | 08-28-2008 |
20080210173 | ANIMAL LITTER - An animal litter with increased moisture retention and accelerated absorbency, a method of manufacture and method of use for indoor urine and feces disposal. An animal litter with a greater surface area and higher moisture retention intended for animals as small as mice, gerbils and hamsters, as well as larger domestic animals. The animal litter is a paper and wood composition treated with a surfactant, which increases moisture retention four to five times its weight. | 09-04-2008 |
20090265979 | Visual Attenuation Compositions and Methods of Using the Same - According to one aspect of the present invention, a visual attenuation composition is provided to be applicable to a landscape to visually attenuate or camouflage the landscape to approximate color characteristics of the surrounding terrain. The visual attenuation composition includes a colorant selected from the group consisting of a pigment, a dye, and combinations thereof, and optionally an additive selected from the group consisting of a flocculent, a tackifier, a stabilizer, and combinations thereof. The visual attenuation composition can be formulated to impart colorfastness as applied for a period of up to 6 weeks or longer. The visual attenuation composition described herein can be premixed with an erosion control medium or a blended mulch product described herein to impart desirable color and colorfastness. Alternatively, the erosion control medium and the blended mulch product can be applied to a ground surface prior to coloring and or color reinforcement with the visual attenuation composition. | 10-29-2009 |
20090265980 | Visual Attenuation Compositions and Methods of Using the Same - According to one aspect of the present invention, there is provided a visual attenuation composition applicable to a landscape to visually attenuate or camouflage the landscape to approximate color characteristics of the surrounding terrain. The visual attenuation composition includes a colorant selected from the group consisting of a pigment, a dye, and combinations thereof, and optionally includes an additive selected from the group consisting of a flocculent, a tackifier, a stabilizer, and combinations thereof. The visual attenuation composition may further include a liquid medium such as water to form a slurry suitable for spray application. The visual attenuation composition described herein can be combined with a soil treatment product to impart desirable color and colorfastness. Alternatively, the soil treatment product can be first applied to the landscape prior to the application of the visual attenuation composition. | 10-29-2009 |
