Abstract: A mounting means for apparatus useful for processing infrared signals including a pyroelectric detector array with a plurality of detector elements, a plurality of electrically conductive epoxy polymer mounting means having two ends and attached at one end to the detector array to provide individual electrical contact for each of the detector elements. The apparatus further includes circuit means attached to the other end of the mounting means for processing electrical signals from the array.

Abstract: A circuit for removing the DC or background representing charge component of a signal to be retrieved from a charge-coupled device to individually compensate for variations of each charge-coupled device circuit. A threshold gate is interposed in a charge flow path between a charge integrating well and an output charge transfer gate. The threshold gate is connected to a potential level which is automatically adjusted to compensate for DC variations in a fixed level of the charge to be extracted from the integrating well. A feedback connection between the threshold gate and the integrating well adjusts the potential level during the integration of a reference charge between the integration of an information signal charge.
