Abstract
A method includes applying a plurality of detection signals to a plurality of receivers, receiving a plurality of echo signals resulted from the plurality of receivers, comparing the plurality of echo signals with a predetermined echo signal distribution pattern, determining the number of the plurality of receivers, and charging the plurality of receivers sequentially using a movable transmitter.
Claims20
A method comprising:
- applying a plurality of detection signals to a plurality of receivers;
- receiving a plurality of echo signals resulted from the plurality of receivers;
- comparing the plurality of echo signals with a predetermined echo signal distribution pattern;
- determining the number of the plurality of receivers through comparing a distance between a first group of echo signals and a second group of echo signals with a predetermined threshold value if the plurality of echo signals comprises two groups of echo signals, and comparing the number of echo signals with a threshold number of echo signals in one group if the plurality of echo signals comprises one group of echo signals;
- and
- charging the plurality of receivers sequentially using a movable transmitter.

A method comprising:
- receiving a plurality of echo signals through a detection grid over a movable transmitter;
- comparing a distance between a first group of echo signals and a second group of echo signals with a predetermined threshold value if the plurality of echo signals comprises two groups of echo signals, and comparing the number of echo signals with a threshold number of echo signals in one group if the plurality of echo signals comprises one group of echo signals;
- determining whether a plurality of receivers is in parallel or in a misalignment manner;
- and
- charging the plurality of receivers sequentially using a movable transmitter.
