POWER TRANSMISSION APPARATUS, METHOD FOR CONTROLLING POWER TRANSMISSION APPARATUS, AND RECORDING MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18358615 titled 'POWER TRANSMISSION APPARATUS, METHOD FOR CONTROLLING POWER TRANSMISSION APPARATUS, AND RECORDING MEDIUM

Simplified Explanation

This patent application describes a power transmission system that wirelessly transfers power to a receiving device using an antenna.

  • The system also measures the voltage and current output from the antenna when the power transmission is stopped.
  • Based on this measurement, the system determines if there is any object present other than the intended receiving device.
  • If an object is detected, the system restricts the power transmission to prevent any potential damage or interference.
  • The system also ensures that the measurement taken during the communication period is not used in the determination process to avoid any inaccuracies.


Original Abstract Submitted

A power transmission apparatus wirelessly communicates with a power reception apparatus using an antenna, wirelessly transmits power to the power reception apparatus using the antenna, measures, in a period during which the transmission of the power is stopped, one or both of a voltage and a current output from the antenna, performs, based on a measurement result obtained by the measurement, a determination process for determining that an object different from the power reception apparatus is present, restricts, in a case where it is determined that an object different from the power reception apparatus is present as a result of the determination process performed by the first determination unit, the transmission of the power, and controls the first determination unit not to use in the determination process the measurement result obtained by the measurement in a period during which communication is performed.
