Abstract: Positive or negative biofeedback is provided by an apparatus using jets of fluid, such as a compressed gas, directed at a targeted area of a body to produce a positive or negative tactile sensation. A stimulus unit is connected to a fluid supply and is positioned on the body, such as the abdomen or back. A sensor unit connected to the stimulus unit is activated, such as by relaxed muscle position or other behavior, which then activates the stimulus unit to open release valves and deliver bursts of small jets of gas to the body. The sensor unit may be remote from the stimulus unit, whereby signals are sent remotely through a control unit to the stimulus unit to activate the release valves.

Abstract: An inflatable and collapsible display screen for electronic devices such as portable computers, TV screens, LCD and the like, which provides a screen area of approximately the size of conventional and comparable portable computer monitor screens, and the like.
