    摘要: Provided is a shoe having a rotating function, and having a novel structure in which a coupling shaft is fixedly coupled by a coupling bolt in a state in which a rotation-preventing column of the coupling shaft is coupled to a rotation-preventing groove, such that the rotation of the coupling shaft is reliably prevented and, simultaneously, the loosening of the coupling bolt is prevented, and, furthermore, a rotating plate can be locked only with foot movements without an operation, performed by the hands, for locking the rotating plate.

    摘要: A kinetic energy generator, system and method of transmitting data are described. The kinetic energy generator includes a piezoelectric element that receives kinetic energy initiated by a user, a rectifier connected with the piezoelectric element that rectifies voltage from the piezoelectric element, a capacitive system of capacitors formed from different materials connected with the piezoelectric element through the rectifier, a short-range transceiver connected with the capacitive system and activated in response to energy storage in the capacitive system reaching a threshold level, and a non-volatile memory that provides at least some of the data transmitted by the transceiver in response to a request from the transceiver. Below an inflection point, the capacitive system stores more energy than one system of one capacitor type and less energy than another system of another capacitor type arranged in the same manner as the capacitive system, and the reverse above the inflection point.
