A wheel chart for visualizing sleep pressure on a person's body by manipulating a series of moveable circular disks positioned on a common axis wherein the wheel includes a first disk representing a circadian (C) process and second disk representing a homeostatic (S) process. The disks are rotatable relative to each other to simulate how the C and S processes increase and decrease sleep pressure.

A multi-layer toy having at least one outer layer adjacent a planar layer or a ball where both the outer layer and the adjacent planar layer or ball each contain related information such that, in play, the information on the outer layer is made to align with the related information on the adjacent planar layer or ball. The information can comprise depictions of objects, things, characters, animals, or words, for a matching game, or the information can comprise numbers for a counting or mental math game. The toy is preferably sized to be hand-held.

A police scene training apparatus is provided. The police scene training apparatus includes a first sidewall, a second sidewall, and a plurality of dowels. Each of the dowels includes a first end secured to the first sidewall and a second end secured to the second sidewall. The plurality of dowels are oriented above and below one another. A plurality of blocks are rotatably disposed about each of the plurality of dowels. Each of the plurality of blocks include a plurality of sides, where at least two of the sides include an image. The sides of the blocks align with one another to form a surface having a plurality of images forming a police investigative scene depiction.

A logic cube for teaching, learning, entertainment and motivation is presented. The logic cube has indicia arranged in well-defined orientations including radial symmetry, pairing pattern and triple logic. The pairing pattern helps to generate meaningful combinations for applications involving sets of two (2). The triple logic helps to generate meaningful combinations for applications involving sets of three (3). Radial symmetry helps generate meaningful combinations involving a greater number of indicia. Applying the exclusion logic helps to avoid meaningless or undesirable combinations and ambigrams help to include indicia which can be read in multiple orientations. The invention of logic cube provides a new function which can be applied to numerous areas such as science, arts, food, fashion, motivation and general education and it provides a novel experience as compared to prior art. The invention of logic cube could be applied to other geometric shapes such as tetrahedron (Pyraminx®) and dodecahedron (Megaminx®) and sizes other than 3×3×3.

A language learning assembly includes a body having at least one first recess and at least one second recess arranged parallel to the at least one first recess. A plurality of blocks are color-coded by syntax category or “parts of speech” and have a plurality of words displayed on each block. The blocks are sized to fit side-by-side within one of the at least one first recess and the at least one second recess to form grammatically correct sentences. Each block can have a different word on at least two faces thereof. Some of the blocks can be configured to display words in a fixed fashion. Some of the blocks can have electronic displays configured to display words electronically.

The invention relates to a device for the representation of tactile characters, in particular in Braille, comprising tactile elements which are combined in groups, wherein a tactile character consists in each case of a matrix of tactile points, which can be arranged in two adjacently arranged columns of points and at least two lines of points, wherein the four possible combinations of two tactile points of tactile points arranged adjacently in a line of points are in each case arranged on a common tactile element.

The present invention relates to a kit used for educational and fun purposes that provides components for creating and visualizing complex geometrical shapes. The kit includes small spheres and pegs that can be assembled into multiple geometric shapes, such as polyhedrons. The shapes are created from separate spheres used as vertices that are connected using pegs. Inner spheres including two holes are placed inside the pegs wherein the holes are used for rotating the shapes both horizontally and vertically. A stand includes horizontal spinning rods and vertical rods that are used for rotating the shapes to enable students to visualize and understand the shapes from all angles. The shapes can be assembled and disassembled as per the preferences of a student. The outer spheres, pegs and inner spheres are manipulable parts that provide hours of fun and learning and help students to learn different aspects of geometry.
