Abstract
Powered by a battery module, an active pen may transmit a signal that is intended for detection by a touch screen. The active pen may comprise an elongated clip member connected to an elongated body member, the free end of the clip member having a ground contact, and the body member having control and charging contacts opposite the ground contact. The free end may be biased such that the ground contact is normally in contact with the control and charging contacts, thereby maintaining the active pen in a signal-transmitting state until separation of the contacts. An electronic device may charge the battery module, optionally responsive to authorization thereof. The electronic device may comprise a partition member to separate the free end of the clip member from the body member, the partition member having contacts corresponding to those of the active pen for enabling charging of the battery module.
