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: Systems, devices, and methods are described for providing, among other things, a neck and spine strengthening device. In an embodiment, the neck strengthening device includes a spinal resistance assembly including at least one resistance component configured to apply a resist force or to resist rotation about a first axis. In an embodiment, the spinal resistance assembly permits lateral neck rotation of a user about the first axis while substantially limiting flexional and extensional movement. In an embodiment, the neck strengthening device includes a device securing assembly configured to physically anchor the device to an anchoring structure. In an embodiment, the neck strengthening device includes a head affixing assembly configured to secure to a head of a user during use.

Abstract: A personal cosmetic appliance that includes a detachable unit including a cosmetic applicator configured to perform a cosmetic treatment on a body part of the user and an applicator communication interface, and a main unit including a main unit communication interface configured to physically and communicatively couple with the applicator communication interface and transmit or receive data to or from the detachable unit.

Abstract: The present invention is directed to systems and methods that couple together optical devices in a manner that prevents damaging light from escaping the coupling except through the devices. In order to prevent damaging light from coming into contact with the user, the present invention obscures the source optical device by using at least one moveable gate to prevent damaging light from being transmitted outside of the coupling until such time as the target optical device is fully inserted into the coupling, thereby preventing light that could potentially damage a person from escaping the system except through the optical device.
