Abstract: The invention relates to decreasing power consumption of wireless charging devices in standby condition. A method for decreasing power consumption comprises feeding at least one detecting signal as a pulse to a wireless charging coil (120) of a power transmitter (100) comprising a charging area, wherein the detecting signal corresponds with an expected resonance frequency of the wireless charging coil (120) measuring a reflected signal caused by feeding the detecting signal, determining whether the reflected signal satisfies a non-resonance condition and activating a power transmitting circuit in response to determining that the reflected signal satisfies the non-resonance condition. The invention further relates to an apparatus and a computer program product.

Abstract: A method is presented for preventing the unauthorized use of a certain protected interface (102) in a processor (101. 101′). An indication (NO PAT, ALARM) of attempted use of the protected interface is generated, and as a response to said indication, at least a major part of the operation of the processor is disabled (DISABLE).
