Systems and methods for controlling an implantable pump are provided. For example, the exemplary controller for controlling the implantable pump may only rely on the actuator's current measurement. The controller is robust to pressure and flow changes inside the pump head, and allows fast change of pump's operation point. For example, the controller includes, a two stage, nonlinear position observer module based on a reduced order model of the electromagnetic actuator. The controller includes an algorithm that estimates the position of the moving component of the implantable pump based on the actuator's current measurement and adjusts operation of the pump accordingly. Alternatively, the controller may rely on position measurements and/or velocity estimations.

This method for locating at least one touch on a touch-sensitive surface of an object comprises the following steps: The monitoring step () comprises measuring () the sensed signal during a time interval (t) starting during a transient phase of the propagation of the transmitted waves, for supplying, to said at least one reception point, information on radiation interfered with by said at least one touch.
