Abstract: Systems, devices, and methods are described for providing, among other things, a multi-axis, multi-exercise device including an extendable and articulated cervical positioning assembly; a head affixing assembly configured to secure to a head of a user; and a multi-exercise system. In an aspect, the extendable and articulated cervical positioning assembly includes at least one articulation element and at least one telescopic element configured to allow maneuverability and repositioning of the head affixing assembly with respect to the multi-exercise system. In an aspect, the multi-axis, multi-exercise device includes at least one of a mechanical resistance component, electromagnetic resistance component, magnetic resistance component, electromechanical resistance component, hydraulic resistance component, or a pneumatic resistance component.

Abstract: 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.

Abstract: Systems, devices, and methods are described for providing, among other things, a neck and spine strengthening device. The strengthening device includes a spinal resistance assembly configured to apply a resist force or to resist rotation about at least a first axis, and a head affixing assembly configured to secure to a head of a user during use. The strengthening device is instrumented with sensors and an embedded computing system configured to securely exchange exercise performance and configuration data with local client devices, and to monitor and record exercise activity and exercise performance data.

Abstract: The brushhead includes a brushhead base member and at least one outer ring of bristles mounted thereto, the brush base member being non-oscillating. An inner assembly is adapted to capture a solid, semi-solid, gel or the like non-Newtonian balm element having shear thinning characteristics. In an embodiment, the inner assembly is adapted to receive energy from an oscillating action of the inner assembly produced by a motor in the appliance to which the brushhead is attachable. Oscillation of the inner portion at a selected frequency and amplitude results in the solid, semi-solid, gel or the like balm element changing to a liquid in a shear thinning effect, the liquid being useful for removal of makeup.

In an embodiment, the inner assembly is adapted to receive energy from an oscillating action of the inner assembly produced by a motor in the appliance to which the brushhead is attachable. Oscillation of the inner portion at a target frequency and amplitude is sufficient to result in the solid, semi-solid, gel or the like balm element changing to a liquid in a shear thinning effect, the liquid being useful for removal of makeup.
