<p>The system has a hands-free control device in a form of a ring (1) fixed on a finger of a user's hand using an attachment unit (11) e.g. elastic band or Velcro(RTM: hook and loop fastener) tape. A wireless remote control (2) processes information obtained from the ring via a short range wireless telecommunication unit (3), and sends a control order to a training collar (5) via a long range wireless telecommunication unit (4). The ring includes a microcontroller connected to switches (12, 13) of the ring, a battery and an antenna of a radio transmitter.</p> |
