Abstract: A balloon system includes a balloon having a balloon membrane extending between an upper apex and a lower apex opening. The lower apex opening extends through the balloon membrane at a balloon lip. A ballonet is within the balloon. The ballonet is coupled with the balloon membrane at the lower apex opening. The ballonet includes a lower ballonet panel having a lower perimeter edge and a ballonet orifice extending through the lower ballonet panel at a ballonet lip and an upper ballonet panel having an upper perimeter edge. The upper and lower ballonet panels are coupled along the respective upper and lower perimeter edges. A lower apex fitting couples the ballonet with the balloon at the balloon lip of the lower apex opening.

Abstract: A high altitude balloon system includes a dual chamber balloon extending from an upper apex to a lower apex with a circumferential edge between the upper and lower apexes. A deflectable diaphragm is within the dual chamber balloon and coupled along the circumferential edge. The deflectable membrane divides the dual chamber balloon into a lift gas chamber formed by an interior surface of the dual chamber balloon and the deflectable diaphragm, and a ballast chamber formed by the interior surface of the dual chamber balloon and the deflectable diaphragm. Optionally, the dual chamber balloon is constructed by interposing the deflectable diaphragm between an upper and lower balloon panels. Each of the upper and lower balloon panels and the deflectable diaphragm are then coupled together along the circumferential edge to form both the lift gas chamber and the ballast chamber.

Abstract: An aerostat deployment system includes fore and aft envelope housings with respective folded fore and aft portions of an inflatable aerostat envelope therein. A support frame is interposed between the fore and aft envelope housings, and a payload is coupled with the inflatable aerostat envelope between the fore and aft envelope housings at the time of deployment inflation. One or more of the fore or aft envelope housings includes a brake configured to control unrolling of the folded fore or aft portions. In one example, the folded aft portion of the inflatable aerostat envelope including a tail portion is inflated prior to inflation of the folded fore portion.

Abstract: A hydration monitor includes a temperature sensor (20; 65) for measuring a subject's core body temperature and a processor (30). The processor is arranged to accept measurements from the temperature sensor (20; 65) and calculate a hydration level in dependence on changes in the measured core body temperature.

Abstract: An improved door design for soft-sided golf cart covers increases the ease of entry and exit. This product features a horizontal swing out design that removes the need for snaps or zippers and significantly increases size of the door opening. This improved door design features a magnetic door that eliminates zipper failure, simplifies entry and exit and improves the overall golf cart cover experience and longevity of the cover.

Abstract: An improved portable golf cart enclosure design featuring a top and two sides that wrap around a typical golf cart to protect occupants from wind, rain and cold. The improved enclosure features a roll-on and roll-up design that improves the installation and removal task over traditional golf cart enclosures. Finally, this invention improves ingress and egress through a horizontal swing away magnetic door design.
