Abstract: A sand spike system anchors a cable in an earthen substrate. A penetrator connected to the cable has folded petal-shaped sections of spring steel propelled into the earth by a propellant. Cables connected to opposite petal-shaped sections help arrest penetration and spread the folded petal-shaped sections outwardly to increase the resistance to tensile loads. Sand spike system may use a delay activated or an electrically initiated propellant to drive the penetrator into the earth instead of mechanical, hydraulic, or pneumatic force. This permits remote initiation of sand spikes from a safe distance on land or underwater. In addition, each sand spike creates far a greater surface area to entrain and use the earthen substrate and not friction to anchor, and, as a consequence, it safely bears greater tensile loads on the cable.

Abstract: A low watch circle buoy system (LWCBS) uses global positioning system (GPS) P(Y) code coordinate sensing and transmission to mark its position in wr depths up to 40 feet to a positional accuracy of 3 meters or less. LWCBS maintains this position with a flotation unit on the water's surface that transmits signals representative of its location. A submerged unit is affixed to a surface at the bottom of the body of water and has outwardly reaching extensions that lie adjacent the surface. The extensions are tethered to the flotation unit by lines that are each connected between a distal part of each of the extensions and the flotation unit. A spool on each distal part each deploys and secures one of the lines to maintain the flotation unit substantially vertically above the submerged unit. These tether lines limit the range (watch circle) the flotation unit may traverse on the water.
