Abstract: A pyroelectric detector array and the method for using it. A series of holes 13 formed through a silicon dioxide layer 12 on the surface of a silicon substrate 11 forms the mounting fixture for the pyroelectric detector array. A series of nontouching strips of indium 14 are formed around the holes 13 to make contact with the backside electrodes 16 and form the output terminals for individual detectors. A pyroelectric detector strip 15 with front and back electrodes 17 and 16, respectively, is mounted over the strips 14. Biasing resistors 18 are formed on the surface of the silicon dioxide layer and connected to the strips 14. A metallized pad 19 formed on the surface of layer 12 is connected to each of the biasing resistors 18 and to the film 17 to provide the ground for the pyroelectric detector array.

Abstract: A miniaturized headset of the post-auricle type is disclosed. The headset microphone may be located in the capsule, or at the end of a swivelable boom near the wearer's mouth. In either case, the headset capsule is contoured to fit over the mastoid process of the skull, in order to provide better weight distribution, comfort and stability. The headset capsule is further contoured by providing a front-to-back concavity in the upper portions of the capsule's sides, so as to generally conform to the curvature of the wearer's head.
