Abstract: A device attaches a videoconferencing device to a mobile support structure to create a mobile videoconferencing apparatus for use in video-based interpretation of communications between a health care provider and a patient. A related system includes a attachment portion and a bracket apparatus fitted to receive and secure the attachment portion and support a videoconferencing device for receiving videoconferencing signals sent by an interpreter to a patient responsive to communications between the patient and a health care provider on a mobile support structure.

Abstract: This invention relates to an electrophoretic display or a liquid crystal display and novel processes for its manufacture. The electrophoretic display (EPD) of the present invention comprises microcups of well-defined shape, size and aspect ratio and the microcups are filled with charged pigment particles dispersed in an optically contrasting dielectric solvent. The liquid crystal display (LCD) of this invention comprises well-defined microcups filled with at least a liquid crystal composition having its ordinary refractive index matched to that of the isotropic cup material. A novel roll-to-roll process and apparatus of the invention permits the display manufacture to be carried out continuously by a synchronized photo-lithographic process.

Abstract: The present invention is directed to a process which comprises removing and stripping off part of the display panel in order to expose and connect the conductor lines on an electrode plate to a driver circuitry. More specifically the process involves (1) preparing a display panel having filled display cells sandwiched between a first and a second substrate layers, preferably by a roll-to-roll process; (2) removing part of a first substrate by asymmetrical cutting by, for example, a die, diamond, knife or laser cutting method to expose the layers underneath (which may include adhesive layer, primer layer, display cell layer and in the case of a display prepared by the microcup technology, the microcup layer and the sealing layer); and (3) stripping off the exposed layers by a stripping solvent or solution. After stripping, the conductor lines on the second substrate are exposed and ready for connection to the driver circuitry.

Abstract: The present invention is directed to methods for improving the performance of an electrophoretic display by modifying the display cell surface. More specifically, the methods are directed to modification of the microcup surface after the microcups are released from the mold. The microcups which have undergone any of the treatment methods of the invention show significant improvement in their surface properties, such as chemical functionality, surface roughness, surface tension, morphology, surface charge, surface reflectivity, surface conductivity and optical properties, particularly optical density in the visible light region. An electrophoretic display formed from the treated microcups has many advantages. For example, the display shows a higher contrast ratio, lower electro-optic response time, lower driving voltage, longer shelf life, higher imageincreasing bistability and higher threshold voltage.

Abstract: The present invention relates to the preparation of non-human animals having chimeric livers, whereby some or substantially all of the hepatocytes present are human hepatocytes. It is based, at least in part, on the discovery that rats, tolerized in utero against human hepatocytes, were found to serve as long-term hosts for human hepatocytes introduced post-natally, and the introduced hepatocytes maintained their differentiated phenotype, as evidenced by continued production of human albumin. The present invention further relates to the use of such animals as models of various liver diseases, including viral invention. Such embodiments are based on the discovery that transplanted human hepatocytes in chimeric livers were found to be susceptible to Hepatitis B virus and Hepatitis C virus infection.
