摘要： Disclosed in one general aspect is a particle interaction characterization instrument that comprises a flow cell for a liquid sample that includes suspended particles and a light source positioned to illuminate the suspended particles in the liquid sample fluid in the sample vessel. A first scattering detector is positioned to receive light from the light source that has been scattered by the particles suspended in sample fluid in the sample vessel at at least one predetermined scattering angle. An ultraviolet transmittance detector is positioned to receive a portion of the light from the source that passes through the suspended particles without being absorbed or scattered. Interaction analysis logic is responsive to both the scattering detector and the ultraviolet detector, and is operative to derive at least one interaction property for the suspended particles.

摘要： In one general aspect, a particle characterization method is disclosed that includes suspending particles in a fluid, causing them to flow past a two-dimensional array detector, and illuminating them as they do so. The method also includes acquiring images of the particles as they flow past the two-dimensional array detector in the fluid, and applying a particle characterization function to the images for at least some of the suspended particles.

摘要： A charging system for uniform charging of charge retentive surfaces such as photoreceptors in imaging systems. The charging system includes corona producing elements and grid elements such as scorotron screens wherein the grid elements are arranged generally parallel to each other and have differentiated grid feature patterns. The differentiated grid feature patterns enable more uniform charging.

摘要： An apparatus (10) for characterizing particles, comprising: a microscope objective with an optical axis and a depth of field; a holder cell (22) configured to position the particles in a generally planar volume below the microscope objective, the planar volume being substantially normal to the optical axis and having a depth that is less than or equal to the depth of field, wherein a portion of the cell holder (22) for positioning in the optical axis of the microscope objective is substantially free of significant spectral features in a Raman spectral range; an x-y stage (20) to move the microscope objective relative to the holder cell (22) in x and y directions to align particles with the optical axis of the microscope objective while the particles are held by the holder cell (22), a detector (18) for acquiring an image of a particle through the microscope objective, a laser operable to illuminate a particle held by the holder cell (22), a Raman spectrometer (16) arranged to obtain a spectrum including the Raman spectral range from the illuminated particle, and characterizing logic operative to characterize the particle based on image processing operations performed on the acquired image and based on the Raman spectrum. The holder cell (22) comprises a first plate (34) and a second plate (36) that are separated by a predetermined distance defining the planar volume depth.

摘要： In a xerographic printing apparatus, a charge device is used to apply a charge to a photoreceptor. The shuttle includes a wiper that cleans a sidewall of the charge device. A tab is disposed adjacent the sidewall to retain toner or dirt accumulated by the scraper. The tab is electrically insulative, and effectively covers the accumulated toner or dirt, to lower the possibility of arcing within the charge device.
