Triple inversion geometric transformations are useful as puzzles, toys, teaching aids, therapy devices, and the like. The transformations include a plurality of hingedly connected polyhedrons, each of the polyhedrons having at least one of a first surface, a second surface, or a third surface. The transformations are configurable between three congruent inverted configurations.

A magnet holder insert comprising a magnet and magnet holder housing designed with internal wall features capable of keeping the magnet properly positioned in the holder device, and external wall features capable of keeping the magnet holder device securely mounted in the finished part. The internal and external fastening elements of the magnet holder housing are designed in such a way as to promote rapid and secure assembly of both the magnet device and the finished part. The exposed surface of the magnet holder device can be configured with flat or dome shaped exposed contact surfaces, depending on how secure or flexible the magnetic joining feature is intended, capable of attaching to another magnet device or a material susceptible to magnetic attraction.

A momentum wheel toy comprises a track having two track sections and a wheel. The wheel has a ferromagnetic axle positioned through its center, with a first end and a second end that each ride upon a track section. The two track sections are separated by a spacer which separates the walls enough to allow the first end and second end of the ferromagnetic axle to ride on the ferromagnetic strips positioned around the perimeter of each of the first track section and the second track section. A handle opening through the device allows the toy to be rocked back and forth, creating the momentum energy for the wheel to go around the track.

A smart block can include a plurality of displays and configurable magnet components to selectively attract or repel other smart blocks. The smart block can include proximity sensors to identify a surface of another smart block close to the smart block to determine if the smart blocks are correctly oriented based on an application or game associated with the operation of the smart blocks. A plurality of smart blocks can be configured to display a portion of a picture (as a puzzle), such that when the smart blocks are oriented correctly they collectively display the complete picture. The smart blocks can be used in conjunction with a smart mat that is configured to move the smart blocks in response to commands received from a remote computing device. The smart blocks and the smart mat can facilitate interactivity with other, remote users, such as between a caregiver and a child.

A normal-temperature heat engine power generation device based on a drinking bird is provided. The device includes a drinking bird body, a piezoelectric module and an electromagnetic module. The piezoelectric module includes a cantilever beam, a piezoelectric sheet arranged on the cantilever beam and working loads arranged at an end of the cantilever beam. when a head of the drinking bird body swings downwards, a tip of a beak can impact the working loads. The electromagnetic module includes magnets, coils and coil magnet conducting columns. The magnets are arranged at a bottom of a spherical bottom of the drinking bird body, and the coil magnet conducting columns sleeving the coils are arranged on a base of the drinking bird body.

A modular electro-mechanical agent having a plurality of modules including mechanical and electrical components, that can be constructed to complete at least one pre-determined task and/or contribute in performing the at least one pre-determined task. The electro-mechanical agent can include extension modules and can be altered as per user preference to add, eliminate or modify any features of the agent for completing and/or participating in a plurality of pre-determined tasks.
