| Number | Title | Issue Date |
| 4050819 | Undersea ranging-communications from altitude via laser An optical means for detecting and/or communicating with underwater objects rom airborne platforms wherein a number of laser sources are collimated so as to illuminate a particular portion of the ocean surface from the airborne platform. Thereafter, use is... | 09/27/1977 |
| 4037328 | Spatial orientation device A navigational device for use by underwater swimmers and divers in which a telescopically extensible boom is releasably and pivotally attached to the swimmer or diver. A compass device such as a magnetometer or fluxgate sensor is mounted at the end of the... | 07/26/1977 |
| 4021661 | Submarine optical communication system with fiber optic depth compensator A system for providing secure communication by use of optical frequency transmission between an aircraft or spacecraft and a deeply submerged submarine. The submarine extends at least one fiber optic cable terminated in a lens arrangement. A flotation uni... | 05/03/1977 |
| 4017146 | Transmitter for use in a laser communication and ranging system A transmitter for extending the operational range capability of laser comications and ranging systems. A narrow laser beam is angle deflected to provide a raster scan equivalent to a broad beam scan.... | 04/12/1977 |
| 3967201 | Wireless subterranean signaling method A relatively low frequency wireless electromagnetic communication link is established through a subterranean lossy medium such as ground or water by launching and propagating magnetic waves of generally vertical magnetic polarization through the interveni... | 06/29/1976 |
| 3964424 | Influence detecting gear with improved towing characteristics 1. A towable detecting gear adapted for dragging over a water-submerged sace comprising a tail portion, a towing cable having its trailing end enclosed in a tail portion and having at least one insulated conductor, a weight member secured to said cable a... | 06/22/1976 |
| 3964051 | Electrostatic communication system A pair of concentric conducting spheres separated by a dielectric layer form a monopole radiator which serves as an antenna for electrostatic waves. Corresponding signal voltages of opposite polarity are placed on the two spheres. At the receiver, variati... | 06/15/1976 |
| 3957296 | Vacuum multiplier This apparatus securely interconnects a line or an instrumentation package to a rigid surface underwater. A suction cup member has a lip which pliably accommodates the surface and allows a trigger mechanism to be brought in contact with the surface. The t... | 05/18/1976 |
| 3951515 | Fiber optic hull penetrator with high channel density An aperture in a hull is sealed by a fiber optic plug system that comprises a coherent array of optical fibers that are fused to form the mechanical and structural equivalent of a thick glass plate. Identical terminal blocks are located on either side of ... | 04/20/1976 |
| 3934082 | Post detection device for eliminating backscatter The deleterious effects of backscattering on a video image received from a urbid environment is minimized by using a vertical raster scan combined with appropriate filtering between the camera and monitor.... | 01/20/1976 |
| 3934077 | Viewing system An underwater floodlit scene is viewed by a TV camera. The first few active TV lines in the scan format, indicative of the illuminated field where backscatter is a minimum, are stored on a video disk. As the apparatus travels over a target area to be view... | 01/20/1976 |
