Apparatus is described which allows a user to simulate crawling motions and provides enhanced movements of the person's truncal spinal muscles and joints. The apparatus comprises a first means for supporting a person in position where there is minimal axial gravity loading of the spine and second means to permit relative motion between axial portions of the spine trunk, especially the upper (thoracic) and lower (pelvic) portions of the person's trunk, while the person remains in the gravity unlo...

The present invention provides a missile seeker simulator (10) including a means for supplying a hot, point-like target against a given temperature background. The missile seeker simulator (10) includes a background source consisting of a hot cavity blackbody (56), fiber optic cable (64), silicon wafer (68), and controllable temperature source (76). The hot cavity blackbody target source (56) generates infrared radiation (58) in a wide bandpass. The fiber optic cable (64) receives and transmits ...

A method for forming a module (hydrodynamic or thermodynamic for example) intended for real-time simulation of the flow mode, at any point of a pipe, of a multiphase fluid stream comprising at least a liquid phase and at least a gas phase. The method comprises using a modelling system based on non-linear neural networks each having inputs for structure parameters and physical quantities, outputs where quantities necessary for estimation of the flow mode are available, and at least one intermedia...

Novel methods, apparatus and kits to provide a new presently-untapped market for state-of-the-art artificial flowers presently sold only as part of artificial plant assemblies that include artificial stems, branches, leaves, etc., the invention comprising various novel improved means, as well as kits including such means, for attaching such artificial flowers to non-blooming (pre-bloom, post-bloom or never-bloom) live vegeation having live stems, branches, leaves, etc., to simulate blooming ther...

An apparatus permits a user to simulate crawling motions and provides enhanced movements of the person's truncal spinal muscles and joints. The apparatus comprises a flat base for supporting a person in position where there is minimal axial gravity loading of the spine, and hand and knee rests respectively fixed and pivoting relative to the flat base to permit relative motion between axial portions of the spine trunk, especially the upper (thoracic) and lower (pelvic) portions of the person's tr...

A method and apparatus for simulating movement within a multi-dimensional space by selecting and reproducing a particular one of a plurality of selectable sequences of video images subsequent to a given sequence of video images. The apparatus comprises an interactive random access video disc system for storing the sequences of video images. Video image windowing means provides as a video output only a predetermined "window" portion of each retrieved video image. The window portion of an ending i...

Cooperating first and second light diffusers are arranged such as to simulate a path of backscattered light between a light impulse transmitter and receiver. The light diffusers respectively extend at inclined angles relative to each other and to the transmitter and receiver. The first diffuser is operative for diffusely reflecting incident light from the transmitter to the second diffuser and the latter is operative for diffusely reflecting incident light from the first diffuser to the receiver...

A method of calibrating eddy current flaw detection equipment comprises placing one or more metallic slugs in surface contact with a material of a type to be tested. The equipment is adjusted to respond to the presence of the slug or slugs producing electrical indications which are equated to defects of one or more levels of severity.

This disclosure relates to a tracer-controlled machine tool adapted for numerical control. The contact gaps actuated by a tracer stylus to control the movement of a cutting tool is electrically simulated and the simulated tracer contact gap is varied with slide velocity. The gap is simulated by a comparison of a velocity signal with a signal proportional to servo position error or lag and the result of this comparison indicates an open or closed contact and actuates a slide drive means in respon...

Tone generating apparatus for a cellular telephone simulates those tones normally sensed by a user of a conventional land-line telephone. The cellular telephone is adapted to communicate with a base station via a service provider which provides different types of service, such as HOME service, ROAM service, or alternate HOME service. A progress tone generator is actuable to generate for the user selected dial tone indications as a function of the detected type of service provided by the service ...
