  • Publication number: 20200227818
    Abstract: An RF energy transmitting apparatus with positioning and polarization tracing function is used for an RF energy harvesting apparatus. The RF energy transmitting apparatus includes a power radar transmitter and a radar controller. The power radar transmitter receives a power source signal and emits an electromagnetic source wave. The radar controller is electrically connected to power radar transmitter and receives a reflected harmonic wave. The power radar transmitter emits the electromagnetic source wave to scan a space. The RF energy harvesting apparatus generates and emits the reflected harmonic wave. The radar controller determines a position and a polarization angle of the RF energy harvesting apparatus after receiving the reflected harmonic wave and to adjust a polarization angle of the power radar transmitter to be within a predetermined angle range with respect to the polarization angle of the reflected harmonic wave sent from the RF energy harvesting apparatus.

  • Publication number: 20200227671
    Abstract: An organic light-emitting diode including an anode, a cathode, and a luminescent layered structure is provided. The luminescent layered structure is disposed between the anode and the cathode. The luminescent layered structure has a luminescent layer and a sensitizer layer. The luminescent layer has a luminescent-layer ground state, a luminescent-layer singlet state and a luminescent-layer triplet state, in which two times of the luminescent-layer triplet state is higher than the luminescent-layer singlet state. The sensitizer layer has a sensitizer-layer triplet state, which is between the luminescent-layer singlet state and the luminescent-layer triplet state.

The luminescent layer has a luminescent-layer ground state, a luminescent-layer singlet state and a luminescent-layer triplet state, in which two times of the luminescent-layer triplet state is higher than the luminescent-layer singlet state. The sensitizer layer has a sensitizer-layer triplet state, which is between the luminescent-layer singlet state and the luminescent-layer triplet state. The molecules of the sensitizer layer at the sensitizer layer triplet layer transfers energy to the molecules of the luminescent layer at the luminescent-layer triplet state and triggers triplet-triplet annihilation upconversion in the luminescent layer such that the luminescent layer emits light of a first color.

  • Patent number: 10644393
    Abstract: An RF energy transmitting apparatus is applied to an RF energy harvesting apparatus, the RF energy transmitting apparatus includes: a power radar transmitter receiving a power source signal and emits an electromagnetic source wave. A radar controller is electrically connected to the power radar transmitter and receives a reflected harmonic wave. After receiving the electromagnetic source wave, the RF energy harvesting apparatus generates and emits the reflected harmonic wave. After the radar controller receives the reflected harmonic wave, the radar controller determines a polarization angle of a reflection signal from the RF energy harvesting apparatus, and the radar controller adjusts the polarization angle of the antenna of the power radar transmitter to be within a predetermined range around the polarization angle of the reflected harmonic signal from the RF energy harvesting apparatus for an optimal received power.

  • Publication number: 20190134462
    Abstract: In a ball movement state measuring system with a ball, a sensing module, a wireless communication module, a power supply and an induction coil, the speed, rotation speed, rotation axis and trace of the ball at first movement state are calculated based on first accelerated speed and first angular velocity of the ball at first movement state and first movement result is obtained by the processor. The speed, rotation speed, rotation axis and trace of the ball at second movement state are calculated based on speed and rotation axis of the ball at first movement state, second accelerated speed and environment parameter of the ball at second movement state and second movement result is obtained by the processor. The ball is forced by gravity, applied force and air resistance at first movement state, and the ball is forced by gravity, air resistance and centripetal force at second movement state.
