The object of the present invention relates to an optimized energy management system of the hardware of electronic RF dice and for the efficient coordination of the same with remote terminals such as, for example, a PC, a tablet, a smartphone or a gaining console and can be conveniently used to significantly reduce the energy consumption of said electronic dice and increase the operating autonomy thereof while also allowing the use of smaller batteries. The proposed solution exploits the standard hardware implemented on the electronic board of said electronic RF dice, allowing to significantly improve the energy performance thereof and, consequently, increasing the life of the attached battery, through a management system of the energy-consuming components of said hardware and, in particular, of the microcontroller and accelerometer installed on said electronic board. The aforementioned system for reducing the consumption of an electronic game die is characterized by: Four different operating modes, i.e., four different activation levels of the hardware components and in particular of the microcontroller and accelerometer. Two different activation thresholds, which can be set and updated dynamically, detected by the accelerometer and aimed at activating the different hardware components and adjusting the transition between said operating modes. Means for the bidirectional transmission, by radio, of data to/from remote game devices, able to detect the active presence of said remote terminals and, particularly, whether or not the data sent has been received. Means for dynamically adapting the parameters of the four aforementioned operating modes and the two activation thresholds to the different use situations of the die, i.e., to different environmental and game conditions.

A mobile object apparatus includes an electric power reception unit that receives electric power transmitted in a non-contact manner from, out of a plurality of power feed apparatuses that are allocated to a plurality of small areas within a predetermined area and are capable of transmitting electric power in a non-contact manner, the power feed apparatus allocated to the small area adjacent to the mobile object apparatus, a drive unit that executes a movement operation on the predetermined area, and an electric power storage unit that stores an electric power amount requisite for the movement operation to the small areas located next to the adjacent small area.

An electromagnetic game board includes a configurable grid of electromagnets under a game board to move game pieces on the board. Alternative to electromagnets is acoustic levitation through soundwave. In an oscillating electric field (four sides), a magnet can create excite ultrasound that quickly contract and rebound its original shape to push out pulses of air.
