A chain mail mesh comprising interconnecting, polygonal links suitably interconnected to define a sheet having each of the interconnecting, polygonal links having at least one degree of freedom of movement in at least one direction with respect to its neighbouring polygonal links wherein each of the interconnecting, polygonal links, interconnected to at least one neighbouring interconnecting polygonal link, combine to form an operative upper surface and an operative lower surface of the sheet, and wherein at least a portion of at least one of the operative upper surface and the operative lower surface of the sheet generally feels smooth with gaps, which produce a calming or pleasing effect when contacted with or moved over, or combinedly contacted with and moved over a human's body portion which being apt to sense of touch. The sheet has a predetermined drape coefficient, nonlinear motion, and is capable of providing relief in stress or pleasure when a human employs the same.

A process for producing a metal alloy balance wheel by molding includes a) making a mold in the negative shape of the balance wheel; b) obtaining a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature; c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel; d) cooling the metal alloy to obtain a balance wheel made of the metal alloy; and e) releasing the balance wheel obtained in step d) from its mold. The process also includes a step for over-molding flexible centering components in the hub.

A device and method of observing mental condition of a user by interacting with an improved swatch of chain mail mesh that comprises interconnecting, polygonal plastic links suitably interconnected to define a sheet having each of the interconnecting, polygonal links having at least one degree of freedom of movement in at least one direction with respect to its neighbouring polygonal links wherein each of the interconnecting, polygonal links, interconnected to at least one neighbouring interconnecting polygonal link, combine to form an operative upper surface and an operative lower surface of the sheet, and wherein at least a portion of at least one of the operative upper surface and the operative lower surface of the sheet generally feels generally smooth with gaps, which produce a calming or pleasing effect when contacted with or moved over, or combinedly contacted with and moved over a human's body portion which being apt to sense of touch. The sheet has a predetermined drape coefficient, nonlinear motion, and is capable of providing relief in stress or pleasure when a human employs the same. The device is a fidget toy, and when used during observation a diagnosis and a therapy tool.

The jewelry article (100) may be an array of closed links (110).

A process for producing a metal alloy balance wheel by molding, the process including the following steps: a) making a mold in the negative shape of the balance wheel, b) getting hold of a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature, c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel, d) cooling the metal alloy to obtain a balance wheel made of the metal alloy, e) releasing the balance wheel obtained in step d) from its mold.
