A system for allowing a shoe wearer to lean forwardly beyond his center of gravity by virtue of wearing a specially designed pair of shoes which will engage with a hitch member movably projectable through a stage surface. The shoes have a specially designed heel slot which can be detachably engaged with the hitch member by simply sliding the shoe wearer's foot forward, thereby engaging with the hitch member.
A novelty footwear item includes an upper, a lower and an opener for protecting the foot of a user and for facilitating unsealing a sealed container with the footwear item.
An anti-G suit simulation system and especially pertains to an arrangement or system for simulating realistic acceleration conditions which are normally encountered during strenuous maneuvers carried out by pilots operating high-performance aircraft, such as jet fighter aircraft. More particularly, there is disclosed an anti-G simulation system wherein aircraft simulator pilots are exposed to physical conditions which rapidly and faithfully simulate and compensate for changes in high-intensity accelerations and gravitational effects or so-called G-conditions which are ordinarily encountered by the pilots of high-performance aircraft during the execution of aircraft maneuvers. Provided is a novel high/low-pressure vacuum system in which a series of solenoid valves are controllably connected to a source of high-pressure operating air and respectively, in a selective mode to high-pressure and low-pressure pumps which are adapted to be actuated responsive to signals received from a simulator computer so as to controllably evacuate the anti-G suit in conformance with specific reductions in G-forces simulated by the system.
