    摘要: Apparatus and controls for indicating the position of a stepping motor rotor as it successively steps and without the need for physically driven encoders or pulse generators, characterized by arrangements for sensing the current, or the rate of change of current, flowing in the motor windings. The intelligence indicating when the rotor reaches successive positions is applied advantageously to a utilization device such as a counter to signal the position of a driven load, and is used to control sequenced energization of the motor windings to create the advantages of a closed loop system but without a driven feedback device.

    摘要: A method for forming a lipid bilayer across an aperture, comprises: (a) providing a cell having a chamber adjacent to a septum comprising a membrane having an aperture capable of supporting a lipid bilayer; (b) depositing one or more lipids on an internal surface of the chamber; (c) introducing an aqueous solution into the chamber to cover the aperture and the internal surface and to form an interface between the solution and lipids; and (d) moving the interface past the aperture at least once to form a lipid bilayer across the aperture.

    摘要: Systems and methods that characterizes a load as a function of position/movement of mechanical components—as induced by such load in the servo-drive system. By running a plurality of motion profiles, corresponding torque/forces that generate such motions can be calculated and readily represented (e.g., as a table) in form of a position dependent load. In addition, a parsing component can decompose or break up a load (which generates a desired motion) to its subparts or constituent values for further simulation analysis.

    摘要: A sensor system (1) for measuring an electrical signal across a lipid bilayer is formed by a cell (2) and an electrical reader unit (3) which are connectable together. The cell (2) is capable of supporting a lipid bilayer across an aperture (11) in a membrane (10) and has a construction which is cheap to manufacture. The reader unit (3) is a portable device which monitors an electrical signal generated in the connected cell (2) to allow analysis of that electrical signal. The sensor system (1) is intended for use outside of a laboratory setting.
