3027 results about "Pressure resistance" patented technology

Pressure resistance. [′presh·ər ri‚zis·təns] (fluid mechanics) In fluid dynamics, a normal stress caused by acceleration of the fluid, which results in a decrease in pressure from the upstream to the downstream side of an object acting perpendicular to the boundary. Also known as pressure drag.

Virtual intelligence shoe with a podiatric analysis system

The virtual intelligence shoe with a podiatric analysis system provided with a portable pair of shoe-like body types thereof, into two of which a miniature electronic module and an enclosed sensor mat are permanently embedded in the shoe-like with a mechanical air package enclosing the electronic module to serve as a shock absorption. A miniature electronic module comprises a transmitting circuit with pressure resistance, shoe temperature and warning buzzer for full memory capacity, which receives the variable pressure and temperature voltage signals, convert them into resistance (ohm) and Celsius, respectively. The electrical signals can be emitted in an infrared light signal. An enclosed sensor mat constitutes a thin, flexible, planar, resilient, and dielectric material that arrays seventy-four positions at strategic geometrical pattern to produce the precision of collecting data exerted by a foot or feet continuously and instantaneously in static and dynamic event during the full weight bearing in various activities. The conjunction of a pair of shoe-like body types, a digital foot scanner, a portable infrared light-receiving unit and a central integrator (servers) form a podiatric analysis system for enabling accurate information. An obtained information of each individual can be stored and analyzed for diagnostic means with respect to the foot or feet maladies. The virtual intelligence shoe with a podiatric analysis system is an unconventional, which can ultimately be used by anyone and capable to produce consistent foot or feet information to implement the changes in the foot or feet biomechanics by altering the shoes, orthoses or other modes. In a preferred form, a pair of shoe-like body types is virtually applied to any type of foot or feet maladies and worn daily as if they were conventional shoes under various terrain conditions.
