Abstract: The present disclosure provides a magnetic resonance type wireless charging circuit, and belongs to the field of wireless charging technology. The magnetic resonance type wireless charging circuit comprises: a high frequency oscillation circuit configured to generate an initial oscillation signal; and a driving circuit configured to generate a transmission signal using the initial oscillation signal; wherein the driving circuit comprises one stage of driving sub-circuit or n stages of driving sub-circuits with (n−1) stages of Direct Current (DC) blocking circuits serially connected thereamong in an alternate manner, where n≥2 and n is an integer, and each stage of driving sub-circuit comprises a frequency doubling circuit and a first frequency selection circuit which are connected in series. In the present disclosure, the frequency of the initial oscillation signal generated by the high frequency oscillation circuit is doubled, so as to increase the frequency of the transmission signal and ensure a transmission distance of the transmission signal, thereby ensuring the effects of wireless charging. When the frequency of the transmission signal is required to reach a certain value, the requirements for switch transistors are reduced, and a wireless charging circuit with good effects can be achieved by using cheap switch transistors, thereby reducing production cost of the wireless charging circuit.

Abstract: The present disclosure provides device and method for measuring cervical vertebra movement. The device comprises a sensor unit, a computation unit, a storage unit and a determination unit. The sensor unit comprises at least one transmission part and at least one reception part. Either of the transmission part and the reception part moves along with user's head, the other fixes relative to user's body. The transmission part transmits detection signals and the reception part receives them. The computation unit computes, based on detection signals, distance changes in a distance between the transmitting and reception part before and after user's head moves. The storage unit stores a mapping table indicating relations between distance changes and movement angles of user's head. The determination unit inquires the mapping table based on distance changes to determine movement angles of user's head. The device is simple, easily operated and practicable.
