A real-time clock for electronic equipment is synchronized by supplying a time signal to a serial communications circuit with the data transmission rate adapted so that one character of the time signal can be read into the serial communications circuit as one character. An implantable light delivery device is coupled to the controller mechanism that receives the power and the control signals to enable a light source to emit sufficient illumination. For cases where the coating and substrate do not bind strongly, the coating can be peeled off to provide foil.
