Methods and systems are provided for provisioning a network by identifying the classes of traffic to be transported in the network as well as the QoS criteria of the identified classes of traffic. The heat element can be connected to an electrical power source and also includes a carrier element to which en electrically conductive heat layer of a PTC material with positive temperature resistance co-efficient is applied. The method optimizes the cost function by jointly updating the positions and the set of switching times to produce an optimal trajectory of the movement. The box-shaped case is filled with a cement material in surrounding relation to the resistive element and the heat radiator. The video frame still image sequence may be displayed according to timing information to resemble play of the video. In some embodiments, the energized biomedical ophthalmic device can include an energized contact lens with a light source in communication with a processor controlling said light source according to the light therapy regimen.
