Patent ID: 7720511

Claim:
An apparatus comprising, an antenna operable to receive an electromagnetic signal and having at least one moveable receiving element that is movable with at least one degree of freedom; a signal strength measuring circuit in communication with said antenna, said signal strength measuring circuit being operable to provide a strength signal based on an electromagnetic signal received by said antenna; a processing system operable to establish an initial population of states of said antenna, to derive servo instruction signals and to output the servo instruction signals, each of the plurality of states corresponds to respective positions of said at least one moveable receiving element; and a servo controller operable to effectuate movement of one of said at least one receiving element based on the servo instruction signals, wherein the initial population is an integer N greater than 1, wherein said processing system is operable to derive a servo instruction signal x i corresponding to a i th state of said antenna for each state i within the initial population and to output the x i servo instruction signal for each state i within the initial population, wherein said servo controller is operable to effectuate, based on the x i servo instruction signal, movement of one of said at least one receiving element for each state i within the initial population, wherein said antenna is operable to receive an electromagnetic signal for each state i within the initial population, wherein said signal strength measuring circuit is operable to measure a signal strength for each electromagnetic signal for each state i within the initial population, and wherein said processing system is further operable to establish a fitness function corresponding to the signal strength for each measured electromagnetic signal for each state i within the initial population.
