Electric power transmitter, electric power transmission method and semiconductor device
First Claim
1. An electric power transmitter, comprising:
- a first detecting unit configured to detect a first placed object on a first electric power transmitting unit;
a second detecting unit configured to detect a second placed object on a second electric power transmitting unit;
a timer unit configured to start driving when the first placed object on the first electric power transmitting unit is detected; and
a judging unit configured to, when the second placed object on the second electric power transmitting unit is detected within a predetermined time period from the driving of the timer unit, judge that the first placed object and the second placed object are one common placed object.
