  • Omnidirectional electromagnet
    Patent number: 10199147
    Abstract: An omnidirectional electromagnet (100) is disclosed. The omnidirectional electromagnet (100) comprises a ferromagnetic core (110) and three orthogonal solenoids (120, 130, 140) disposed about the core (110). Each solenoid (120, 130, 140) is adapted to receive a current from a current source to control an orientation and a magnitude of a magnetic field generated by the omnidirectional electromagnet (100). One or more omnidirectional electromagnets (100) can be used as a single magnetic manipulation system. The magnetic field generated by the omnidirectional electromagnet system can be used to control at least one of a force, a torque, an orientation, and a position of an adjacent magnetic object.

  • Force measuring device and related methods
    Patent number: 8353222
    Abstract: A testing apparatus and related methods are disclosed. In one embodiment, the testing apparatus may include a platform, a first plurality of cables, a second plurality of cables and a third plurality of cables, with each of the cables coupled to a respective load cell. The first plurality of cables may suspend the platform and be substantially parallel to each other. The second plurality of cables may be coupled to the platform, may be substantially parallel to each other cable of the second plurality of cables, and substantially perpendicular to each cable of the first plurality of cables. The third plurality of cables may be coupled to the platform, and each cable of the third plurality of cables may be substantially parallel to each other cable of the third plurality of cables, and substantially perpendicular to each cable of the first plurality of cables and the second plurality of cables.
