A waveguide polarization recovery system both polarizes the input light energy for use with an LCD imager and converts the polarity of unusable light energy to add to the illumination of the LCD imager. Example sensors include HEMTs with a thin gold layer on the gate region and bound antibodies; a thin gold layer on the gate region and chelating agents; a non-native gate dielectric on the gate region; and nanorods of a non-native dielectric with an immobilized enzyme on the gate region. When the standard rigging fixture is placed next to the termination, this swaging sleeve is swaged over a portion of the standard rigging fixture in order to lock the standard rigging fixture to the termination. The tube forms a stub which projects away from the base and which is adapted to be coupled to the outlet port of the filter. The rotating operating systems create a consistently changing attack surface for remote attackers. This maintains the symmetry in shape of the metal dummy pattern as viewed from the gate electrode.
