  • Patent number: 9914363
    Abstract: Disclosed is a method for efficiently retrieving a charger to supply electric power to an electric vehicle and achieving maximum wireless recharging efficiency, using visible light communication, upon wirelessly recharging the electric vehicle. Wireless visible light communication can be realized, using the existing head lamp installed at the vehicle. Accordingly, it is unnecessary to provide separate communication equipment. In addition, enhanced physical security, efficient charger retrieval, and maximum wireless recharging efficiency can be achieved by virtue of straightness of light.

    Abstract: A sensor, a time alignment apparatus, a time processing method, and a time alignment method are provided. The sensor begins to sense at least one sensed data at a first local time instant. The sensor transmits a response message at a second local time instant. The response message carries the at least one sensed data, the first local time instant, and the second local time instant. The time alignment apparatus receives the response message at a first global time instant. The time alignment apparatus calculates a second global time instant that the at least one sensed data being sensed according to a required transmission time between the time alignment apparatus and the sensing apparatus, a clock skew rate between the time alignment apparatus and the sensing apparatus, the first global time instant, the first local time instant, and the second local time instant.
