Abstract
A power supply apparatus includes a power supply unit that wirelessly outputs power to an electronic apparatus, a control unit that determines that a predetermined object is detected if a reflection corresponding to power outputted is greater than or equal to a first value and determines that the predetermined object is detected if a change of a reflection corresponding to power outputted by the power supply unit is greater than or equal to a second value.
Claims20
A power output apparatus comprising:
- an output unit that wirelessly outputs power to an electronic apparatus;
- a detection unit that detects a value relating to a traveling wave of power output by the output unit and a reflected wave of power output by the output unit;
- and
- a control unit performs at least one of a first process and a second process, wherein the first process includes a process for determining whether a change of a value detected by the detection unit is not less than a first predetermined value, wherein the second process includes a process for determining whether a value detected by the detection unit is not less than a second predetermined value, and wherein the control unit causes the output unit to output charging power for causing the electronic apparatus to charge a battery if a change of a value detected by the detection unit is less than the first predetermined value and a value detected by the detection unit is less than the second predetermined value.
A method for controlling a power output apparatus, the method comprising:
- detecting a value relating to a traveling wave of power output by the power output apparatus and a reflected wave of power output by the power output apparatus;
- performing at least one of a first process and a second process, wherein the first process includes a process for determining whether a change of a detected value is not less than a first predetermined value, and wherein the second process includes a process for determining whether a detected value is not less than a second predetermined value;
- and
- outputting charging power for causing an electronic apparatus to charge a battery if a change of a detected value is less than the first predetermined value and a detected value is less than the second predetermined value.
A non-transitory computer-readable storage medium storing a program that causes a computer to perform a method for controlling a power output apparatus, the method comprising:
- detecting a value relating to a traveling wave of power output by the power output apparatus and a reflected wave of power output by the power output apparatus;
- performing at least one of a first process and a second process, wherein the first process includes a process for determining whether a change of a detected value is not less than a first predetermined value, and wherein the second process includes a process for determining whether a detected value is not less than a second predetermined value;
- and
- outputting charging power for causing an electronic apparatus to charge a battery if a change of a detected value is less than the first predetermined value and a detected value is less than the second predetermined value.
