    摘要： A system for detecting fluorescence emitted from a plurality of samples in a sample tray is provided. The system generally includes a plurality of lenses positioned in a linear arrangement, a linear actuator configured to translate the plurality of lenses, an excitation light source for generating an excitation light, an excitation light direction mechanism for directing the excitation light to a single lens of the plurality of lenses at a time so that a single sample holder aligned with the lens is illuminated at a time, and an optical detection system for analyzing light from the sample holders. In certain embodiments, the optical detection system includes a light dispersing element configured to spectrally disperse the light from the sample holder being illuminated, and a lens element configured to receive light from the light dispersing element and direct the light onto a light detection device. A method of scanning a sample tray having a plurality of samples positioned in sample holders to detect fluorescence is also provided.

    摘要： An electrically biased magnetic brush is used to remove background toner particles from a photoreceptor, and an electrically biased reclaim roller is used to remove the toner particles from the magnetic brush. Before contacting the photoreceptor once again, the bristles of the magnetic brush are discharged by a charge bar, the bristles having been charged by the biased reclaim roll. A second reclaim roller biased to the opposite polarity of the first may also be used to remove toner particles from the magnetic brush to be certain that toner particles of opposite polarities are removed from the magnetic brush. In addition, if desired, a mixture of two groups of carrier beads may be used to form the bristles of the magnetic brush, the groups having different tribo-electric properties.

    摘要： A method of producing viewable images is disclosed wherein a layer of electrostatic charge is deposited on the surface of a 3d metal oxide that is disposed in an ambient temperature below the Neel temperature. The temperature at certain portions of the surface of the 3d metal oxide is increased to exceed the Neel temperature such that the 3d metal oxide undergoes an insulator-to-metal transition whereby the layer of electrostatic charge is selectively dissipated to form an electrostatic latent image corresponding to those portions of the surface that are subjected to an increase in temperature. The electrostatic latent image is then developed to form a viewable image. In one embodiment of the present invention the temperature is increased to exceed the Neel temperature by imaging a character pattern comprised of modulated radiant energy onto the surface of the 3d metal oxide. In another embodiment of this invention the temperature is increased to exceed the Neel temperature by transferring thermal energy forming a character pattern to the surface of the 3d metal oxide. In a further embodiment of this invention the electrostatic latent image is formed by depositing an electrostatic charge on the surface of the 3d metal oxide, the latter having certain portions thereof at a temperature that exceeds the Neel temperature therefor.
