First Claim
Patent Images
1. An apparatus to track a location of an object, the apparatus comprising:
- an intensity determining unit determining an intensity of an ultrasound based on a distance between the object and the location tracking apparatus;
an emitting unit emitting an ultrasound having the determined intensity;
a sensing unit sensing the emitted ultrasound; and
a location calculating unit calculating the location of the object based on sensing time information of when the ultrasound is sensed, and updating the distance based on the calculated location.

Abstract
Disclosed are an apparatus and a method of location tracking. The location tracking apparatus may calculate a location of an object using an ultrasound. In this instance, an intensity of the used ultrasound may be determined based on a distance to the object, thereby reducing unnecessary power consumption.
