Fidget Walkers

As of August 2023, Fidget Walkers are a patent-pending invention in the US. More patent applications will be filed elsewhere shortly as well.

FIG. 4B is a perspective view of an embodiment similar to that from FIG. 4A, but the terrain path 29 of fidget walker device 412 is confined by guardrails 70 in this embodiment, and capped with an enclosure 60.

Abstract: A fidgetable device that relays haptic feedback via magnetic coupling to hands and fingers, when an operator uses an outside magnet to drag an inside magnet over a rugged interior surface. This haptic experience is akin to walking a pet on a retractable leash. Thus the designation fidget walker. Said haptic device, with its acoustic side effects, is also widely applicable in a variety of fields including percussion instruments, underwater switches, magnetic locks, tabletop games, and even automated machineries.

Universal Mixture Maker

As of August 2023, Universal Mixture Maker is a patent-pending invention in the US. More patent applications will be filed elsewhere shortly as well.

FIG. 4A is a perspective view of the fourth embodiment of the present disclosure, showing a universal mixture maker 140 with a conical solute cup, a conical solvent container, and corresponding threaded tube and rod capable of fastening said cup to said container.

Abstract: A volumetric instrument serving as a universal mixture maker. The instrument comprises fixed-shape solute cups that can be submerged in and fastened to solvent containers. The design allows a human operator to run an iterative method which finds a solution to a set of multivariate equations that would otherwise require situation-specific analytical calculations and the use of weighing scales. The iterative method can solve for one or more variables including solute volume, solvent volume, final mixture volume, and final solute concentration level. Cups and containers act as a mechanical calculator with a single parameter for the operator to manually adjust: how much of a solute cup to submerge in a solvent container. The mechanical calculator reduces mixture equations down to two markings for the operator to visually align: an output mixture marking on a cup, and a volumetric marking on a container.

Fidget Ice Packs

As of August 2023, fidget ice packs are a patent-pending invention in the US. More patent applications will be filed elsewhere shortly as well.

FIG. 5A is a perspective front view of the fifth embodiment, nicknamed The Bar, which is a revision of the fidget cold pack from the second embodiment, with additional, insulated circular grooves on surrounding faces, two of such insulated grooves are visible on the front face. Freezer gel inside the cold pack is shown in a cutaway.

Abstract: A cold pack that can be fidgeted in a human hand. The cold pack encases a heat-transferring substance and provides a rigid portion suitable for being securely held by and readily fidgeted with fingers of said human hand. Heat-conducting grooves and heat-insulating surfaces are built into the rigid portion, with acute edges, jutting bumps, guard rails and other textures to provide grip. Fingertips alternate between holding the cold pack by said grooves and surfaces, thereby applying dynamic cold therapy to the same fingertips, rest of fingers, the hand, and other body parts requiring treatment for swelling, inflammation and trauma arising from friction, compression or minor burn injuries. Timely application of dynamic cold therapy can thus prevent formation of blisters in fingers and hands commonly seen in string players, musicians, sportspeople and workers caused by repetitive contacts with objects, and by unexpected contacts with hot surfaces.
