Abstract: Reel devices, systems, and related methods are disclosed. The reel devices are modular and include an automatic shift assembly that shifts to provide a mechanical advantage when used to tighten a cord. For instance, the reel devices are configured to provide a first drive ratio and automatically transition to a second drive ratio in response to a torque force. The reel devices include a drive assembly and a shift assembly. The drive assembly includes a cycloidal gear.

Abstract: A nonaqueous ointment for the treatment of persons who are identified by their ophthalmologist to have an infection of common parasites in and around the follicles of the eyelash. The invention is a highly viscous mixture of inert components and antiparasitic powder, as well as a method of application considering the unique composition's qualities. The unique ointment and application method eradicate the pathogens entirely by taking into account their general behavior and lifecycle. Once an infection is identified using instruments readily available to eye doctors in their offices, the ointment is applied once daily to the base of the eye lashes by an ointment tube with an ophthalmic tip. The ointment is applied shortly before bed, over the course of several months. Existing methods of treatment have additional side effects and are largely ineffective, with the parasites often recovering in number after treatment has ceased.
