摘要:
A system automatically prepares and analyzes a macromolecule prepared from a complex liquid mixture. To prepare the macromolecule, a controller executing executable instructions, such as compiled software or firmware, operates a hydraulic subsystem in response to operational input, which may be interpreted by the executable instructions at run-time. To analyze the prepared macromolecule, an apparatus for capillary electrophoresis includes a liquid source, inlet chamber, capillary electrophoresis column, and controller that may operate under control of executable instructions and operational input in a similar manner. The system may require validation and approval by a regulatory body, such as the FDA. Based on the de-coupled configuration of the executable instructions and operational input, the system can be validated and approved with the executable instructions independent of the operational input, and vice-versa. A method for distributing the system based on this feature is also provided.
摘要:
A digitizing tablet is disclosed in which two sets of circuitous conductive lines form grids each connected at one end to a surrounding conductive loop. All outputs are measured from the conductive loop as a multiplexor sequentially grounds the grids one at a time. The outputs are fed through linear spatial filters which are used to produce intermediate signals which are in turn combined to arrive at raw position signals for a position indicating coil located over the work surface. Separate sets of linear spatial filters may be used to produce two raw position signals differently responsive to tilt which can then be combined to arrive at a true position signal insensitive to tilt.
