Abstract

An array of pneumatic stimulating nodes with integral pneumatically operable ANDing is disclosed. These stimulating nodes may be used to convey spatial orientation information to an individual in an attitudinally ambiguous situation via direct stimulation of his skin. The stimulating nodes of the instant invention may be arranged orthogonally in an array if this is convenient, or in a wide range of other configurations. The pneumatic stimulating nodes of the invention are comprised of three layers, and upper layer, diaphragm layer, and a lower layer which may be separately injection molded from suitable materials, for example, urethane thermoplastic elastomer, and fused together using radio-frequency welding techniques to form the complete stimulating array.

Claims

1. A pneumatic stimulating node comprised of an upper cavity contiguously connected to a source of operating fluid pressure, a lower cavity contiguously connected to a source of operating fluid pressure, a diaphragm disposed between said upper and lower cavities with integral attached valve which when opened forms a contiguous pathway for the operating fluid within one of said cavities of the instant invention to an external area, said valve being operably opened when pressure is applied to the said cavity not contiguously opened to said external area by said valve.

2. The pneumatic stimulating node of claim 1 with control valves controlling the transmission of fluid pressure to the upper and lower cavities of the instant invention.

3. A plurality of the pneumatic stimulating nodes of claim 1 disposed in an array.

4. A plurality of the pneumatic stimulating nodes of claim 1 disposed in an array and connected with commonly contiguous fluid pressure sources whereby logical ANDing of operating fluid sources may be used to selectively operate individual nodes.

5. The pneumatic stimulating node of claim 1 manufactured from elastomeric materials.

6. The pneumatic stimulating node of claim 1 manufactured from elastomeric materials and non-elastomeric materials.
