Wrist Pin Sensing System And Method

US Patent:
2009015, Jun 18, 2009
Filed:
Dec 18, 2007
Appl. No.:
11/959259
Inventors:
Daniel R. Kemppainen - Calumet MI, US
Assignee:
MICHIGAN TECHNOLOGICAL UNIVERSITY - Houghton MI
International Classification:
G01B 11/26
G01M 15/06
US Classification:
7311501, 356614, 250215
Abstract:
A method, and a system employing the method, for determining a position of a rotational part in a reciprocating machine. The system includes a quadrature encoder and an interrupter coupled to the rotational element. As the interrupter rotates with the wrist pin, the quadrature encoder generates some binary signals based on the rotation of the wrist pin. A digital-to-analog converter then converts the binary signals into a single analog signal. The system then wirelessly transmits the single analog signal for processing by other remote components.

Rotational Torque Measurement Device

US Patent:
2011001, Jan 20, 2011
Filed:
Jul 15, 2010
Appl. No.:
12/837253
Inventors:
Paul A. LaVigne - Hancock MI, US
Daniel R. Kemppainen - Calumet MI, US
Glen L. Barna - Houghton MI, US
International Classification:
G01L 3/08
G01L 3/10
US Classification:
702 41, 73862324, 73862321
Abstract:
A device for measuring torque applied through a rotating member. A first torsion reference member is fixedly coupled to the rotating member at a first axial position and a second torsion reference member is fixedly coupled to the rotating member at a second axial position. A first detector detects the passage of the first torsion reference member past the first detector upon each full rotation of the rotating member and to generate a first signal upon each passage of the first torsion reference member. A second detector detects the passage of the second torsion reference member past the second detector upon each full rotation of the rotating member and to generate a second signal upon each passage of the second torsion reference member. A controller calculates a phase difference between the first signal and the second signal relative during rotation of the rotating member under a torsional load.
