  • Patent number: 6725992
    Abstract: Engagement characteristics of electromagnetic friction clutch pack assemblies disposed in, for example, motor vehicle transfer cases are improved, especially at the transition between static and dynamic friction modes, by superimposing a random noise signal on an otherwise smooth analog or stepped digital signal. The controller and driver for the clutch includes a random noise (signal) generator having an output which is superimposed on the controller output generated in response to signals from various sensors disposed on the vehicle. When the controller inputs cause clutch engagement in accordance with the controller software, an engagement signal comprising both a drive portion and a smaller random noise portion is supplied to the electromagnetic clutch operator. Improved, less perceptible clutch engagement action is thereby achieved.

  • Publication number: 20040075949
    Abstract: An actuator assembly for use in a data storage device is described that has features that reduce off-track writes due to coil popping. The fantail portion of the actuator includes thermal restraint features that engage with the over-mold, and the thermal restraint feature are positioned prevent the over-mold from separating from the actuator as a result of the over-mold and the actuator having different coefficients of thermal expansion. The thermal restraint features reduce the length of effective interface between the actuator and the over-mold acted upon by shear forces due to coefficient of thermal expansion mismatch. In one example, the thermal restraint features are holes that extend through the actuator, to allow the over-mold to flow through the holes and connect on both sides of the fantail during molding, effectively interlocking the fantail portion to the over-mold.
