A motion simulator comprises a cabin (10) which is supported on the ground (14) by at least three feet (12). Each of the feet can swivel about an essentially horizontal axis, the cabin (10) having a swivel drive (26) for each foot. Each foot (12) bears a wheel (30) by which it rolls along the floor (14).

A motion simulator, comprising a platform carried by at least three pairs of length-adjustable legs, wherein the connection between each leg and the platform comprises a first coupling, wherein the distance between the first coupling of one pair of legs is smaller than the distance between the first coupling of different pairs, wherein, viewed in the top plan view, at least two first couplings are located on a first circle and at least two further first couplings on a second circle, wherein the ...

A motion sensor may detect linear and/or angular acceleration and/or angular velocity of a body relative to one axis, two orthogonal axes or three orthogonal axes. Movement of the body or reference structure may be detected relative to one or more spinning rotors. The rotor(s) may be suspended for rotation and/or other movement relative to the reference structure without physical contacting the reference structure. In one embodiment, the rotor(s) may be electrostatically suspended in such a way ...

A motion simulator comprising a base support connected to a motion platform by hinged legs. The motion simulator is provided with an actuator for moving the motion platform relative to the base support. Preferably, each leg is defined by a lower leg portion and an upper leg portion with a separate actuator connecting the leg portions for providing actuating legs that also stabilize movement of the motion platform.

A motion transducer for measuring the displacement of, for example, shafts in gas control modules. The shaft 14 carries two magnets 10, 12 each of hollow cylindrical form, the magnet 10 presenting a south pole everywhere over its external cylindrical face and the magnet 12 presenting a north pole everywhere over its external cylindrical face. The shaft 14 moves vertically past an array of Hall-effect sensors 18-24 to produce sinusoidal voltage outputs at the sensors. The outputs are combined in ...

A generally planar resilient polymeric member having a viscous film is positioned between a fixed and movable element of the vehicle accessory and provides controlled friction between the two. In a preferred embodiment of the invention, the fixed member is a housing for a vehicle storage compartment and the movable member is a pivoted door. The dampening device has one side secured to either the door or the housing and an opposite surface including a viscous material. The device is compressibly ...

A safety device for train passengers which permits barriers to rise and lower as trains (66) pass. Ridge posts (58) are secured by ridge post mounts (64) on a train undercarriage (68). Ridge wheels (60) spins on the ridge posts (58). As the train (66) moves into a train station, the ridge wheels (60) will first encounter an inclined ramp guide (1) or a mechanical ramp guide (52) and spin along the spin wheel ridge (4), causing the motion barrier wall (2) to move downward, below the platform leve...

A flight simulator wherein the pitch, roll and yaw axes are separated from the trainee to provide a more realistic simulated flight experience in that the trainee feels a translation as well as a rotation of his body as he performs a simulated climb, turn, or roll.

An electrical initiator (10) includes spool halves (12,14) releasably held together by a coiled retaining wire (42). A link wire (42) also holds a spool (46) fixed to spool half (12) against connector body 16 and the other spool half (16). A cavity on the interior of the two spools physically retain a tensilely loaded shaft (18). An electric current passing through the link wire (42) causes it to become brittle and break releasing the spool halves and contained shaft (18).

Apparatus for detecting motion by producing a signal in response to motion, transmitting the produced signal and receiving the transmitted signal which is converted to auditory and electrical outputs, with an ear phone jack connected to an auditory output, an on-off switch connected to the signal converter and a set of indicator lights connected to an electrical output.
