Abstract: A system and method for actuating controlled stimulation of a patient in a confined medical position helps sooth and entertain a patient receiving medical treatment while resting on a support member, like a dental chair. The system provides a support member, and integrates at least one air actuated animated member, such as a mobile or figurine, proximal to the support member, to enable animated motion by the animated member through pressurized air. Pressurized air causes the animated members to articulate in animated, colorful movements. Audio signals are also generated by the animated member in response to the pressurized air. The animated member can be a mobile or a cartoon character with joints, axes, and limbs that move when engaged by pressurized air. The patient or caregiver control distribution of the pressurized air by manipulating a foot valve and an arm valve to control the animated members.

Abstract: A modular polyhedral object having at least four external faces which each have in the assembled state a different form and/or color design, is formed from several individual building blocks that each forms a part of the form or color design of each external face. The building blocks are joined together loosely or with releasable connecting means, wherein the building blocks of each module have at least four differently designed side faces. A form-congruent assembly of the object is created by arranging the individual building blocks so as to produce matching external faces on each side of the object, as well as to produce matching respective opposing side faces of the building blocks inside the object with vertically and horizontally matching coded pairs. A modular polyhedral cube-shaped object with at least five differently designed side faces is also described.
