  • Patent number: 11929626
    Abstract: A method that includes: transmitting, by an electronic device, a first detecting signal when the electronic device is in a reverse wireless charging mode; receiving, by the electronic device at a gap moment between at least two adjacent moments at which the first detecting signal is transmitted, a second detecting signal transmitted by a wireless charging device; and if the second detecting signal received by the electronic device meets a preset condition, automatically switching, by the electronic device, from the reverse wireless charging mode to a forward wireless charging mode.

  • Patent number: 11013314
    Abstract: Portable, electrically driven, handheld sonic personal skin/hair care device includes a housing and a drive assembly to which is coupled a treatment member. The treatment member may include active ingredients incorporated during manufacturing that safely resist and inhibit the growth of mold, mildew and bacteria. The drive assembly includes a stator assembly, armature assembly, mounting member attached to the housing, elongated pivot arm having a first end directly coupled to the armature assembly and a second end directly coupled to the mounting member, and mounting arm having first and second ends, the first end being directly coupled to the armature assembly and the second end being directly coupled to the treatment member such that the stator, when energized, causes oscillation of the armature in an arcuate manner about a pivot point located at the mounting member in turn causing the treatment member to oscillate relative to the housing.
