An eating utensil that prevents food from dropping during loss of fine motor control by way of a retractable cover is disclosed. The head of the eating utensil is operatively associated with the retractable cover so that the latter is movable relative to the former between an open configuration and a closed configuration preventing food from spilling from the head of the utensil regardless of the head's orientation. An actuated arm engages both the utensil head and an elastic membrane of the retractable cover to effectuate selective control between the open and closed configurations. The actuated arm is operatively associated with system circuitry and electronics housed in a handle of the eating utensil, whereby the user can control power to the retractable cover.

A playful and therapeutic device for the rehabilitation of fine manual motor skills; specifically for the rehabilitation of patients with rheumatic, traumatic and neurological pathologies who have fine motor sequelae in the wrist, palm and fingers of both hands; characterized by having a cultural theme related to the Guelaguetza of Oaxaca and by comprising a container with a lid and handle that will serve to store and transport other components such as a puzzle, cylindrical pieces with and without slots, cards and tweezers.The device facilitates playful and therapeutic activities for mental, sensory, and physical stimulation; such as placing and removing the lid of the container to perform pronation and supination movements and palmar grasp; assembling a puzzle to perform pronation and supination movements, palmar grasp, four-finger pinch, and visuo-manual coordination; fitting cylinders into holes to perform two-finger pinch, three-finger pinch, and visuo-manual coordination movements; inserting cards into slots to perform pronation and supination movements, two-finger pinch, and visuo-manual coordination; and hooking tweezers onto a surface to perform pronation and supination movements, two-finger pinch, and visuo-manual coordination.

Provided is a rotating device 100 capable of positioning a rotating member 102 at a target angle position with high accuracy. The rotating device 100 comprises a fine movement mechanism 109 that is provided with a base member 110 and a coarse movement mechanism 101 that is provided with a housing 104 and a rotating member 102 at least part of which is housed in the housing 104 and that is disposed on the base member 110. The rotating member 102 is capable of rotating about a rotating member axis 103 with respect to the housing 104, and the entire coarse movement mechanism 101 is capable of rotating about the rotating member axis 103 with respect to the base member 110.

In order to shorten the standby time of a fine-motion mechanism and effectively reduce vibration of the fine-motion mechanism, the present invention proposes a technique for controlling a fine-motion mechanism, comprising: setting the operating speed of the fine-motion mechanism during a first transition, which is a transition of the fine-motion mechanism from a first operating state to a second operating state different from the first operating state, and during a second transition, which is a transition from the second operating state to the first operating state, to a speed lower than the operating speed of the fine-motion mechanism in the first operating state and the second operating state by a period of time equivalent to (N - 1 / 2) cycles (N is a natural number) of the principal natural vibration of the fine-motion mechanism that occurs during the first transition or during the second transition; and causing the fine-motion mechanism to operate at the operating speed in the first operating state or the second operating state after the period of time equivalent to (N - 1 / 2) cycles has passed, and thus reducing vibration of the fine-motion mechanism that occurs during the first transition and during the second transition (see Fig. 2B).

A wheelchair having at least one force element that is elastically deformable, wherein deformation of the at least one force element becomes more and more intense with the application of increasing force, resulting in natural damping of the coupled-in force, which may be detected by a sensor such that the wheelchair according to the invention may be controlled in a targeted manner for fine movements as well as for faster, coarser movements.
