The wireless power transmitter includes a power transmission antenna including a plurality of patch antennas for wirelessly transmitting power, a sensor, and a processor, wherein the processor may be configured to create a first clutter map representing a reflection characteristic of an object positioned around the wireless power transmitter based on, at least, first data obtained by the sensor during a first period, store the first clutter map, compare a difference between the first clutter map and second data obtained by the sensor during a second period with data contained in the first clutter map, create a second clutter map corresponding to the second period based on a result of the comparison, determine a position of an organism using the second data and the second clutter map, and control the power transmission antenna such that a magnitude of the RF wave is less than a predetermined value based on the position of the organism.
Abstract:
An apparatus and a method manage a telephone number in a terminal, which can separately manage telephone numbers, a call to each of which an attempt to originate has been made and to each of which the call has failed to be connected, and then enable a convenient attempt to re-originate a call to the telephone number. The apparatus includes: a memory including a temporary list which stores a non-connecting telephone number, to which a call has been originated and has failed to be connected; and a controller for performing a control operation so as to store a particular telephone number in the temporary list as the non-connecting telephone number, when an attempt to originate a call to the particular telephone number is made and the call fails to be connected to the particular telephone number.
