Abstract

The present invention relates to a system for the control and monitoring of functional devices for the disabled with energy from outside the body, comprising actuator element(s), data-processing element(s), and control element(s) connected to the actuator element(s) to the processing element(s). The system further comprises a sensor element which is connected to the control element(s) and can transmit one or more signals for the control and monitoring of functional devices for the disabled. The present invention also relates to the procedures necessary for the remote control and monitoring of the system.
