Methods and apparatuses are provided for controlling a wireless power transmitter. First power for charging a first wireless power receiver is transmitted. Demand power information of a second wireless power receiver is received. The demand power information includes a maximum power for the second wireless power receiver. A controller identifies whether the wireless power transmitter is capable of providing the maximum power. A power adjustment command is transmitted to the second wireless power receiver, if the wireless power transmitter is not capable of providing the maximum power. The power adjustment command requests to reduce a magnitude of power to be received by the second wireless power receiver to a level within a range that the wireless power transmitter is capable of supporting. Second power for charging the first wireless power receiver and the second wireless power receiver is transmitted based on at least the reduced magnitude of power.

Method for distributing wireless charge power for multiple wireless power receivers

One embodiment of the present invention is capable of providing a method for efficiently transmitting power for multiple wireless power receivers by distributing the power of the wireless power receivers as power which matches the respective wireless power receivers in accordance with demand power information from the multiple wireless power receivers.

A relay apparatus relays a signal received from a transmitting apparatus to a receiving apparatus, and includes a receiver configured to receive a signal from the transmitting apparatus, and a transmitter configured to repeatedly transmit a predetermined symbol interval of the received signal to the receiving apparatus.

Relay apparatus, receiving apparatus and control method thereof

Provided are a transmitter, receiver and method of transmitting and receiving Orthogonal Frequency-Division Multiplexing (OFDM) symbols. The transmitter includes: a sub carrier grouping part configured to perform grouping of a plurality of sub carriers into a plurality of groups, and to change phases and/or amplitudes of the plurality of sub carriers by group; and a transmitting part configured to generate at least one OFDM symbol from the plurality of sub carriers of which the phases and/or the amplitudes have been randomly changed by group, and to transmit the OFDM symbol and information about the grouping.

Transmitter, receiver and controlling method thereof

According to a preferred aspect of this invention, locations of defects on a semiconductor wafer are found using semiconductor defect inspection instrumentation. Defect composition can also be determined using inspection instrumentation. Wafer defects are represented on a wafer defect map using markings wherein locations of the markings on the map correspond to the locations of the defects on the wafer. The markings also preferably represent a defect type and/or composition. Color-coded dots, for instance, can be used to represent like defect causes or types with like colors. Graphs can be prepared to display defect characteristics using distributions and skews to facilitate quick statistical analysis of the defects. In this manner, wafer defects can be analyzed quickly and efficiently based on characteristics thereof, including, for example, defect type, composition, and cause. This information can be used to help prevent future defects during mass production, thereby improving yield.
