A new method is provided for the interface between a heat spreader and the substrate of a thermally improved PBGA package. The apparatus includes one or more rotationally biased partial-circle structures and one or more temperature-sensitive releases connected to the partial-circle structures. The input offsets prevent backflow of current from the output to either of the first electrodes when the first or second input is nearly equal to the output voltage. A database representation of the objects is used to configure the system and receive updates to the system by an administrator. In some embodiments, a communications device implements a service policy for assisting control of the communications device use of a service on a network; and monitors use of the service based on the service policy, in which the implementation of the service policy is verified. Such repositioning is maintained over time by the force of the magnetic elements, allowing the damaging effects of heart dilation to slow in progression or reverse.
