Abstract: A wireless charging apparatus of a wireless charging system obtains, in a charging period, channel information of a transmission channel and a waveform parameter used to indicate a waveform of an electromagnetic wave signal; generates a target electromagnetic wave signal based on the channel information and the waveform parameter; and sends the target electromagnetic wave signal to a to-be-charged device through the transmission channel. The channel information includes signal attenuation and a transmission delay that are of an electromagnetic wave signal transmitted through the transmission channel. The to-be-charged device converts the received target electromagnetic wave signal into a direct current signal, and performs charging based on the direct current signal. The target electromagnetic wave signal determined by the wireless charging apparatus can adapt to channel transmission.

Abstract: Techniques and apparatus are described for use in far-field wireless power transmitter. A far-field wireless power transmitter uses beamforming to localize a power signal transmitted from an array of antenna. A multi-tone signal is used for the power signal, where the signal transmitted from each of the antenna is formed of a plurality of tones having a frequency center and separated by a uniform frequency difference, and relative delays and/or relative amplitude differences are introduced into the signals from the different antennas of the array so that a beam is formed in a region where a far-field wireless power receiver's antenna is located. By use of two such transmitters placed to either side of the receiver, a hot-spot for the multi-tone power signal can be formed in the region of the receiver's antenna, with lower field values away from the region.

Abstract: An instrumental approach enabling evaluation of efficacy of skin care products is disclosed. Common problems shared by existing methods include first the difficulty whether to test the entire human face, or just focus on the key locations (not determined yet); the difficulty in conducting a repeatable test when human face is hard to fix on and changes between different persons; and how many different skin attributes to test for making a reliable and complete judgment. The instrumental approach of the process tests a sample at once to obtain all the information needed. It shows good repeatability and sensitivity. It yields necessary yet sufficient information in numbers.
