Methods for using a conditional access system to modify access control information maintained at a set-top box or another client system. Apparatus and methods according to the present invention comprise a light source providing at least three wavelengths of illumination that are each loss modulated, phase delayed and simultaneously directed to illuminate the target. The inertial bodies is provided by single or plural number. With the linear sensor indicating that a negative sense of the magnetic field is detected, the angular sensor detects a second 180-degrees of angular position. Based on the application layer protocol, an adapter is selected from among a plurality of adapters that are accessible to the network element.
