BATTERY CHARGING SYSTEM FOR STYLUS Russian patent published in 2019 - IPC H02J7/00 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. According to embodiments, the charging system comprises a stylus comprising an energy storage device for powering the active functionality of the stylus, and a charging circuit electrically that is connected to the energy storage device and configured to provide charging current for recharging the energy storage device. Further, the stylus comprises a magnetically-attractable element comprising ferromagnetic material disposed in a ring formation on the outer surface of the stylus, a magnetically-attractable element that is electrically coupled to the charging circuit to form a terminal of the charging circuit, and a magnetically-attractable element that is configured to be received on a dock using magnetic attraction to the permanent magnet of the dock to bring the stylus into the docked position in which the magnetically-attractable element contacts the charging contact of the dock to thereby cause the charging circuit to receive charging current from the dock.

EFFECT: providing a reliable charging system for the stylus.
