A new digital imagevideo camera that directly acquires random projections of the incident light field without first collecting the pixelsvoxels. The method includes determining traffic data values for traffic over a network link that is used to provide one or more services to one or more customers, where the traffic data values are taken at intervals for a predetermined range of time. The movable foot support is adapted to be engaged by the user’s feet to absorb the energy of movement in a first direction and to provide the user with a bouncing movement, which the user may translate into a movement of the movable body support in the opposite direction. Thereafter, during each scan of the process controller, the optimizer routine calculates the optimal operating target of each of the complete set of control and auxiliary variables and provides the determined target operating points for each of the selected subset of control and auxiliary variables to the model predictive control routine as inputs.
