Definitions

  • the present invention relates to the portable exercise / conditioning equipment area that uses rotary dampers based on intelligent fluids to provide controllable resistance.
  • the invention concerns the use of an intelligent fluid and an electrical or magnetic excitation of said fluid to provide controllable resistance to the movement of a set of rotor blades with holes within a housing filled with the fluid where said housing is enclosed in the exercise device to provide the user with resistance.
  • the design of the rotor blades considers a particular curved shape to increase the contact area between the fluid and the blades and thus increase the resistance range.
  • the previous characteristics result in a compact rotational damper, thus minimizing size and weight and allowing the portability of the resulting device and its use in various applications.
