    摘要： The present invention is a whiteboard method and system (100) having automated projection calibration that does not require user interaction. The method and system are accomplished by placing sensors (302) beneath a target surface and projecting a projected pattern to discover a geometric correspondence between the target surface and the projecting device. Optical sensors (32) are preferably employed to sense the presence of the projected pattern on the whiteboard. The input data is used with a mapping function or translation matrix for converting whiteboard coordinates to screen coordinates, which are then used for mapping the coordinates to a cursor position. When the geometry of the whiteboard surface is known, and the locations of the optical sensors within this geometry are known, the information about which projector pixels illuminate which sensor can be used to calibrate the projecting device with respect to the whiteboard.

    摘要： The present invention provides solutions and methods for preserving biological material that enable organs, tissues and cells to be stored for extended periods of time with minimal loss of biological activity. The inventive solutions are substantially isotonic with the biological material to be preserved and are substantially free of univalent oxyanions and of iodide. The solutions comprise a first neutral solute having a molecular weight of at least about 335 and a solubility in water of at least about 0.3M, and a second neutral solute having a molecular weight of less than about 200 and having both hydrophilic and hydrophobic moieties. The inventive solutions preferably contain CaSO.sub.4, together with combinations of anions and cations from the protein-stabilizing ends of the Hofmeister series, such as K.sub.2 SO.sub.4. In particular methods using solutions comprising raffinose or trehalose and trimethyl amine oxide or betaine, wherein the solution is substantially isotonic with the biological material and the solution is substantially free of iodide, dihydrogen phosphate, bicarbonate, nitrate and bisulfate are described.

    摘要： The present invention includes interactive communication systems that incorporate several beneficial embodiments including an interactive tray system, an electronic presentation messaging system, an interactive podium, and a key drive system. The interactive tray system enables a single, transferable interactive unit to be fastened to a communication medium, turning into a fully interactive medium. The electronic presentation messaging system enables the e-mailing of presentations and notes to and from components of the interactive communication system. The interactive podium increases conventional podium mobility, enabling both the presenter, and podium, to move and be moved about the room without attention to wired connections. The key drive system replaces the conventional Y-connector of the key drive technology by effectively integrating the key drive in the device, thus only having one connector, and eliminating the need to change connectors from the key drive, to the USB connector, upon software driver loading.
