Systems, devices, and methods are described for providing, among other things, an electrodynamic contactless braking system. In an embodiment, the electrodynamic contactless braking system may include plurality of electromagnet assemblies arranged and configured to have alternating magnetic field orientations. In an embodiment, each electromagnet assembly may include an air gap formed between a first electromagnet pole and a second electromagnet pole. In an embodiment, each electromagnet assembly is configured to generate a magnetic field of a character and for a duration sufficient to induce eddy currents on an electrically-conductive element moving within the air gap of each of the plurality of electromagnets. In an embodiment, the electrodynamic contactless braking system may include a controller operatively coupled to each of the plurality of electromagnets, the controller configured operate the plurality of electromagnets in parallel.

The present invention may be embodied as a system or method for dynamically exercising a user's neck muscles. The system includes a headset, an arm attached thereto, a weight, and at least one motor to move the weight, for example, about the arm. The weight may be mounted eccentrically on a radial track that is rotatable by one motor and moved linearly by another motor. The direction of the arm, the distance between an apex of the headset and the weight, the eccentricity of the weight on the axis, and the speed of rotation of the motor are all parameters that can be adjusted by the caregiver or user, either manually or via controlling software.

Disclosed is an elastic exercise strap with a gripping portion that merges into a loop or aperture. The strap can be connected to a sports helmet by threading the extended gripping portion around a part the helmet and then inserted through the loop or aperture. By pulling on the attached strap the neck muscles can be exercised.
