    摘要: A method and apparatus for generating a poly phase signal set from a single signal output of a single phase instrument. The method comprising: generating a first signal output X representing the single signal output; processing the single signal output to generate a time delayed version Y_Raw of the single signal output by a time delay T; and processing the time delayed version Y_Raw to compensate for frequency changes in the single signal output and generating a second signal output Y of the poly phase signal set. The second signal output Y is displaced from the first signal output X by about 90 degrees.

    摘要: A hypodermic needle comprising a tubular, elongated, generally cylindrical wall defining an internal longitudinal bore extending longitudinally therethrough along a longitudinal axis, The longitudinal bore has forward and rearward openings. The cylindrical wall is constructed and arranged to form a forward pointed end and a rearward pointed end. The rearward pointed end is defined by an annular end surface forming the rearward end of said cylindrical wall. The rearward pointed end terminates in a rearwardmost point lying in an imaginary plane disposed perpendicularly to the longitudinal axis. The annular rearward end surface defines an imaginary plane inclined with respect to the imaginary plane perpendicular to the longitudinal axis. The cylindrical wall has a laterally facing opening spaced from the rearward opening of the longitudinal bore, and the longitudinal bore is restricted at a position between the rearward opening and the laterally facing opening.
