  • Patent number: 9204018
    Abstract: The invention relates to a system and method for adjusting the color of image objects based on chained reference points and/or light gradients to account for the effects of lighting conditions that can vary across different environments, according to an implementation of the invention. To chain reference points and/or characterize light gradients, the system may determine a color shift value, which represents the effects of lighting conditions of a target environment (in which the lighting conditions may be unknown) relative to a reference environment (in which the lighting conditions may be known). The chained reference points, gradient characterization, color shift values, and/or other information may be used to store a delta map that characterizes the lighting conditions of an environment so that it may be reused for subsequent color shifts without re-characterizing the environment.

  • Patent number: 9119875
    Abstract: A silica particle for medical imaging includes a bridged silane fluorescent dye incorporated throughout the particle matrix. Copolymerization of a bridged silane fluorescent dye (e.g., (R?O)3Si—R—Si(OR?)3, where R is a fluorescent organic bridging group, and where R? is a methyl or ethyl group) and a tetralkoxysilane (e.g., Si(OR?)4, where R? is a methyl or ethyl group) generates particles of a predetermined size and shape. This leaves the surface of each particle available for further modification to facilitate dispersion of the particle into different media. Hence, a surface modifier may be subsequently bonded onto the particle surface. In some embodiments, poly(ethylene glycol) is selected as the surface modifier to increase dispersion of the silica particle in an aqueous media. In some embodiments, the particle is porous allowing for an additional functionality (e.g., a secondary imaging material, such as magnetic nanoparticles, and/or a pharmaceutical drug) to be loaded within the pores.

Said fluorescence imaging device comprises a light source emitting radiation for excitation of a fluorescent marker in a range of emission wavelengths of between 600 and 900 nm. The light emitted by the illuminating device is filtered by a low-pass filter, of which the cut-off wavelength is below the emission range of the fluorescent marker, but is nonetheless able to show an increase or fluctuations in the attenuation for wavelengths above the emission range of the fluorescent marker, the product of the attenuation of the filter of the detector and of the attenuation of the low-pass filter of the illuminating device leading to an attenuation by a factor of at least 106.

  • Patent number: 8946611
    Abstract: A color filter is formed using a simple manufacturing method, and bias application to a pixel separating electrode allows sensitivity in low illumination intensity to be improved. In a solid-state imaging element, in which a plurality of unit pixel sections are disposed two dimensionally on a side closer to a front surface of a semiconductor substrate or a semiconductor layer, each unit pixel section having a light receiving section for generating a signal charge by light irradiation, an adjoining unit pixel section is formed in the same color to allow for lesser alignment accuracy of the color filter. A pixel separating electrode is formed in the adjoining unit pixel section, and a signal charge is shared by bias application during low illumination intensity, thereby improving an effective photodiode area.

  • Publication number: 20150028226
    Abstract: Even when the distance from an objective lens to a sample differs, the distribution of light from the sample can be detected accurately. A first lens 23 for converting light from the objective lens into parallel light is composed of a concave lens part 32 having a concave curved face 32c in a center portion of a flat face 32a, and a convex lens part 33 having a convex curved face 33c around a flat face 33b. Further, the first lens 23 includes first and second regions for diverging light through the flat face 33b and the concave curved face 32c and a third region for collecting light through the convex curved face 33c and the concave curved face 32c. When the sample is placed on a sample table while being sealed in a two-dimensional electrophoresis substrate, light totally reflected by a side surface of the objective lens is caused to enter the second region. In contrast, when the sample is directly placed on the sample table, the light is caused to enter the third region.

  • Patent number: 8941049
    Abstract: A readout apparatus and method for processing spatially distributed signals is disclosed. The readout apparatus and method may reduce/eliminate the impact gain variations among a plurality of sensing channels. This is done by continuously varying the dispersion properties of a signal distribution device, which may induce a spatial shift of the signal distribution during data acquisition, allowing the distributed signals to move across the sensor area. Shifting of the distributed signals may occur multiple times, hence eliminating the impact of gain variation across the sensor array. The accumulated data may be re-assembled subsequently to complete the readout operation.

  • Patent number: RE45493
    Abstract: An image sensor system using offset analog to digital converters. The analog to digital converters require a plurality of clock cycles to carry out the actual conversion. These conversions are offset in time from one another, so that at each clock cycle, new data is available. A CMOS image sensor converts successive analog signals, representing at least a portion of an image, into successive digital signals using an analog to digital circuit block. Multiple clock cycles may be used by the circuit block to fully convert an analog signal into a corresponding digital signal. The conversion of one analog signal into a corresponding digital signal by the circuit block may be offset in time and partially overlapping with the conversion of a successive analog signal into its corresponding successive digital signal by the circuit block.
