A handheld touch apparatus for providing a variety of tactile sensations to the fingers and thumb of a hand of a user. The touch apparatus includes a multi-faceted block body having an outer surface defined by a plurality of planar faces joined together by radiused edges that meet together to form rounded corners. The block body is sized for holding within the palm of the user's hand and for being supported, rotated and manipulated by the fingers and thumb of the same hand. The touch apparatus further includes tactile features extending from the planar faces of the block body and that are selectively movable relative to their associated planar faces. The tactile features are contained within the volume of an imaginary sphere defined by the rounded corners and isolated from the tactile features on adjacent planar faces by the radiused edges of the block body.

A jigsaw-type puzzle has pieces that do not need to be flipped or turned prior to, or during assembly of the puzzle. The pieces have peripheral shapes or outlines that are symmetrical along at least one axis, with mirror images being printed on both sides of each piece so that either side of each piece can be used during assembly. Each piece shows a portion of a two-dimensional image, such that when the pieces are assembled, the two-dimensional image is completed. Each piece has first and second sides, with each piece portraying the same portion of the two-dimensional design, such that either side of any piece can be used to complete the puzzle. The invention is applicable to edge pieces, corner pieces and inner pieces, including square pieces with rounded tabs and voids that “interlock,” as well as non-traditional shapes, with or without interlocking joints, and tabs and voids with other shapes.

A three-dimensional puzzle comprising a plurality of cuboid puzzle blocks together forming a predetermined three-dimensional puzzle shape, wherein each puzzle block comprises either a male or a female connecting element on each of at least three sides of the puzzle block; wherein the connecting elements for the respective puzzle block are configured such that each puzzle block is unique.

Puzzle kits include a first puzzle and a second puzzle, each of which is formed of a plurality of polyhedral modules, or polyhedrons, connected by hinges in a continuous loop. Each polyhedron includes four faces, six edges, and at least one magnet disposed adjacent to at least one face. Magnetically stabilized assemblies of the first puzzle and the second puzzle form at least a convex polyhedrons, such as a cube.

Exemplary embodiments are disclosed of systems and methods for providing location-based security and/or privacy for restricting user access. In an exemplary embodiment, a system is configured to restrict and condition access to the system and/or data based on a user's selection of location-based data from a plurality of options presented by the system for selection by the user. The plurality of options include the location-based data and one or more other options that are selectable by the user.

A puzzle of chocolate-based material puzzle pieces is formed by providing a transfer sheet having a design of food-grade material on a first side of the transfer sheet and providing a puzzle piece template having passages shaped as pieces of the puzzle. The puzzle piece template is arranged on top of the first side of the transfer sheet. The passages of the puzzle piece template are filled with a chocolate-based material. After crystallization, the chocolate-based material in the passages of the puzzle piece template form the chocolate-based material puzzle pieces of the puzzle. The chocolate-based material puzzle pieces are removed from the template.

A handheld touch apparatus for providing a variety of tactile sensations to the fingers and thumb of a hand of a user. The touch apparatus includes a cubic body having an outer surface defined by a plurality of faces that are planar and orthogonal to one another and joined together by radiused edges that meet together to form rounded corners. The cubic body is sized for holding within the palm of the user's hand and for being supported, rotated and manipulated by the fingers and thumb of the same hand. The touch apparatus further includes tactile features extending from the faces of the cubic body and that are selectively movable relative to their associated faces. The tactile features are contained within the volume of an imaginary sphere defined by the rounded corners and isolated from the tactile features on adjacent faces by the radiused edges of the cubic body.

In exemplary embodiments, an AI (Artificial Intelligence) enabled system is developed, configured, and/or intended to facilitate the offensive, defensive, and logistical capabilities of a person engaged in warfare in some direct form. This encompasses scenarios ranging from the solo unit behind enemy lines, the operational deployment of forces and resources, to strategic theater. Exemplary embodiments include building or configuring a highly advanced and aware system, facilitated by AI, driven by cloud and edge computing, to allow decisions and tactical advantage be deployed and calculated at the level it needs first. Exemplary embodiments may be configured to address both the kinetic real world as well as digital cyberspace, incorporate offensive and defensive technology, and be primarily driven by the concept to augment forces to support and counter threats as well as malicious enemy AI.
