    Abstract: Methods and apparatus are provided for detecting a non-intended object of power reception by a power transmitter. Power transmission for communication is performed, when the load change is sensed that has a value greater than or equal to a predetermined threshold. It is determined whether a subscription request, for subscribing to a network is received within a predetermined time period. The power transmission for communication is stopped when the subscription request is not received within the predetermined time period. Power is transmitted to a power receiver that has transmitted the subscription request, when the subscription request is received within the predetermined time period. It is determined whether a leakage power value exceeds an allowable range, when the power state report is received from the power receiver. The transmission of the power to the power receiver is stopped, when the leakage power value exceeds the allowable range.

    Abstract: A method and power transmitter for efficiently controlling power transmission to one or more power receivers in a wireless multi-power transmission system are provided. The method includes performing, when a predetermined measurement cycle arrives, a load measurement; comparing a current load measurement value with a previous load measurement value; determining whether the current load measurement value is increased over the previous load measurement value by at least as much as a first predetermined threshold; gradually increasing, when the load measurement value is increased over the previous load measurement value by at least as much as the first threshold, a transmission power value until a request for a subscription to a wireless multi-power transmission network from a power reception target within a predetermined time limit; and stopping, when the request for the subscription is not received before the time limit is exceeded, power transmission to the power reception target.
