Abstract: A marine or land habitation system includes a habitable chamber and a monopole column supporting the habitable chamber at a first end of the monopole column. The monopole column includes a second end, opposite the first end, for mounting in the seabed or dry land. The habitable chamber is moveable with respect to the column both rotationally and vertically.

Abstract: Scale habitable units are disclosed for use in marine environments, such as the open sea, which are inexpensive to assemble and maintain, while providing habitable space.

Abstract: Marine habitation units are disclosed for use in the open sea. Each unit includes a habitable chamber; a column including a first end, and a second end, opposite the first end, the second end for mounting in a sea bed; and, and, a segment in communication with the habitable chamber, and the first end of the column. The segment is moveable both substantially vertically, and, rotatably, allowing the wherein the habitable chamber and the column to move substantially vertically, and, rotatably, with respect to each other.

Abstract: A system for collecting soil solution samples including a sampling device arranged to contact soil and coupled to a vacuum source, and a suction unit for automatically controlling pressure and time of operation of the vacuum source to provide suction for withdrawing solution from the soil through the sampling device and abrupt release of the vacuum at the end of a pre-defined sampling period, and a method for collecting soil solution samples including coupling a sampling device to a vacuum source, planting the sampling device in soil to be monitored, automatically controlling pressure and time of operation of the vacuum source to provide suction for withdrawing solution from the soil through said sampling device, and automatically stopping the vacuum source and abruptly releasing the vacuum at the end of a pre-defined sampling period.

Abstract: A weapon including a grip portion, an independent extension extending from each end of the grip portion and configured to extend partially around a hand of a user; at least one portion of at least one of the extensions being shaped to create painful pressure when pressed against an adversary, and a method of making the weapon.

Abstract: A bottle cap, and a method for making it, the bottle cap including a cap member having internal screw threads adapted for sealing engagement with a neck of a beverage bottle; and a bi-directional tubing coupler integrally formed with the cap member, the tubing coupler including a first coupling element for coupling a first tube inside the bottle and including a second coupling element coupling a second tube outside the bottle, to permit drinking of a beverage from inside the bottle through the tubes and the tubing coupler.

Abstract: A liquid dispensing device for use with a container for holding a liquid under pressure, the dispensing device including a cap portion for sealingly connecting the dispensing device to the container, a conduit for permitting outflow of liquid under pressure from the container, and a holder for a pressure valve providing for increasing the air pressure in the container, wherein the cap portion, conduit and holder are assembled to form a single unit before use, and a method for forming such a liquid dispensing device.

Abstract: A preferred handguard for a rifle includes a pair of essentially identical half-grip pieces each having an elongated body with a generally triangular lateral cross-section, including two exterior sides and a mating side. The exterior sides of the triangular cross-section are formed substantially at a right angle to each other. The mating side of the triangular cross-section is centrally hollowed and has outer edges that form a mating surface for mating with the other half-grip piece to enclose an air space surrounding a section of the rifle barrel. Longitudinally extending accessory mounting rails are formed on each of the exterior sides and are recessed in the half-grip piece such that the rails are located inside a laterally extended generally semi-octagonal outline defined by an end wall. Removable elastomeric rail covers that replicate the semi-octagonal outline are provided to form a substantially continuous shape with the end wall.
