A deformable focal plane array for imaging systems is disclosed. A keyboard is mounted in the base of the enclosure and is coupled to provide input to the microprocessor. An intermediate point 24 of the second line 22 is grounded to a grounding 26 via an insulation resistor 28. The system further includes at least two conformal windows in a spherical side of the turret payload. Noisy estimates are inherently reduced in the touch-screen display system by providing shunts across certain drivers in the system that also allow for detection of a \u201cno touch\u201d state.
