Stone Robert L: Low light level, underwater, viewing device. The United States of America represented by the Secretary of the Army, Kelly Edward J, Berl Herbert, Holford John, January 22, 1974: US3787688 (30 worldwide citation)

An underwater viewing system is described which provides enhanced viewing means of an image intensification tube. The unit is binocular and permits wide angle direct viewing as well as the more narrow intensified field of view best suited for submerged operation at night or in a low light environmen ...

Graves Howard T: Point source discriminator thermal alarm. The United States of America represented by the Secretary of the Army, Kelly Edward J, Berl Herbert, Holford John E, May 21, 1974: US3812483 (6 worldwide citation)

An alarm system is provided for a scanning type far infrared system. The eo signal is processed by a gated pulse blanking system which permits automatic surveillance of one or more windows within the scene displayed. Any significant change within the selected window triggers an audible or visible al ...

Flogaus William S, Masutani Mitsumasa: Method and apparatus for defocus compensation of a convergent beam scanner. The United States of America represented by the Secretary of the Army, Kelly Edward J, Berl Herbert, Holford John E, November 5, 1974: US3846007 (3 worldwide citation)

The inherent defocusing caused by deflecting a convergent light beamed im at the surface of a rotating mirror is minimized by shifting the axis of rotation as the mirror is rotated. The required motion is provided by essentially rolling the mirror over a cylindrical surface.
