Abstract:
A system for recording writing performed on a surface includes a rechargeable stylus, a rechargeable eraser, and a charging station for one or both of the rechargeable stylus and the rechargeable eraser. Each of the rechargeable stylus and the rechargeable eraser includes a pair of charging rings. The charging rings are disposed so as to contact a corresponding pair of charging contacts on a receptacle on the charging station for the stylus or the eraser. The receptacle, charging contacts, and charging rings cooperate to charge rechargeable stylus or the rechargeable eraser when the stylus or eraser is placed into the receptacle.
