Disclosed is a geometric puzzle comprising a plurality of three-dimensional components of at least one type, each component of the same type being derived by notionally dividing a fundamental shape into a plurality of equal parts, said fundamental shape being selected from the group consisting of a regular tetrahedron having edges of equal length and a regular pyramid with a square base and also having edges of equal length, said components being capable of assembly into multiple composite shapes. Each component may be equal and identical to one another or each pair of components may comprise mirror images of one another. Surfaces of said components may be provided attractive magnetic elements to hold said components in a composite shape.

A game device having a three-dimensional playing surface with strategically positioned points and a method of playing a game on the game device which has a three-dimensional playing surface with strategically positioned points whereby the game is played by at least two players alternately claiming the points.

Method and apparatus for heating and / or compressing plasmas to thermonuclear temperatures and densities are provided. In one aspect, at least one of at least two plasmoids separated by a distance is accelerated towards the other. The plasmoids interact, for instance to form a resultant plasmoid, to convert a kinetic energy into a thermal energy. The resultant plasmoid is confined in a high energy density state using a magnetic field. One or more plasmoids may be compressed. Energy may be recovered, for example via a blanket and / or directly via one or more coils that create a magnetic field and / or circuits that control the coils.

Playground equipment comprising a revolving ring for standing or sitting on is according to the invention composed of ring segments (1) which are connected by means of connecting pieces (2) for forming a closed ring. The revolving ring is mounted somewhat above the base by means of legs (3) and by adapting the length of the legs, an inclined revolving plane may be obtained. The structure itself comprises a stationary ring (5, 6) on which a revolving ring (4) provided with wheels or rolls (9, 10) may roll. The revolving ring (1) fits tightly about the stationary part of the playground equipment and it is not possible to separate the parts apart once the playground equipment has been assembled and held together by means of locking rings (12).

An electronic device is protected from unauthorized access by use of a security wrap which comprises at least a substrate, a security screen, a layer of adhesive and decoy pattern. The security screen is disposed over one side of the substrate and includes a pair of screen terminals and a conductive path between the pair of screen terminals. The layer of adhesive bonds the first side of the substrate to the electronic component with the security screen sandwiched there between. The decoy pattern is at least partially impervious to X-ray and overlays said security screen.

A variable difficulty balance board for standing desk and fitness use is provided. The balance board facilitates the conditioning and rehabilitation of the nerves, bones, muscles, and joints of the body by limiting the range of motion and biomechanical forces around the longitudinal and lateral axes. The balance board comprises a deck, a fulcrum receiver, and a fulcrum insert. The fulcrum insert is press-fit into a fulcrum cavity of the fulcrum receiver. The fulcrum insert extends outward from the fulcrum receiver and provides an area where the balance board can pivot. The fulcrum insert may be replaced by the user such that it may occupy either a first orientation or a second orientation within the fulcrum cavity. The first orientation and the second orientation configures the fulcrum insert such that it provides a lateral or longitudinal axis of balance relative to the deck, respectively.

An ear instrument assembly includes a base unit and a tool. The base unit includes a first housing defining an opening. The tool is movable between a storage position in which the tool is partially disposed into the opening such that the tool is secured to the first housing and a use position in which the tool is removed from the opening such that the tool is spaced from the first housing. The tool includes a tip contained inside the first housing when the tool is in the storage position. The tool includes a camera at least partially disposed in the tip of the tool, and the tool includes a curette attachable to and detachable from the tip of the tool.

This invention relates to the field of surgical implants, and in particular to a method of treating biomedical material, and more particularly bioprosthetic heart valves and tracheas, to mitigate calcification when implanted in a mammalian body.

A system, method and apparatus for making evident, diesel exhaust fuel (DEF) contamination is provided. The system, for use with a diesel exhaust fluid system, includes a container having an opening to receive a diesel exhaust fluid. A reactive device is located near the opening and reactive upon exposure to one or more predetermined components potentially present in a fluid pourable into the container through the opening. The reactive device is not reactive to the diesel exhaust fluid.
