A motion device which provides circulatory stimulation and therapy of vascular disorders of legs. The motion device comprises two pivoting pedals positioned in a heel area on a base plate. The pedals are connected to a mechanism positioned between the pedals. The mechanism comprises a crank system having a shaft which is parallel to the pivoting axis of the pedals so that the pedals must be moved in push-pull motion. The shaft is connected with a transmission gearing which drives a flywheel. Thu...

A motion sensor comprising a permanent magnet suspended in pendulum fashion at one end of a length of cord string so as to be capable of swinging freely within an electrical coil when the motion sensor is moved. The movement of the magnet induces an emf in the coil which can be detected by simple electronic circuitry. The motion sensor is extremely simple but yet highly effective to detect both shock movement or a gentle motion.

A motion sensor is provided having within a casing a resonant element with a magnet arranged therebeneath and a freely movable ball made from magnetizable material disposed there above. A change in the position of the ball causes a change in the density of the flow of the magnetic lines of force and as a result, a resonance voltage is produced in the resonant element thereby indicating motion. As the motion is detected by electronic means, high sensitivity is assured, and such sensitivity, furth...

A traverse motion for a winder which comprises a traverse drum having a spiral groove formed in the circumference thereof; a traverse guide which moves along the spiral groove, guide rails for controlling the movement of the traverse guide, a drum case covering the traverse drum, and a lubricating member fixed to the drum case so as to spray oil mist against the traverse drum.

Disclosed is a motion sensor for sensing movement of an object to be monitered, the motion sensor comprising a support disk having a concave upper surface, a ball rotatably put on the support disk, and a piezoelectric element attached on the support disk. If the object attached with the motion sensor inclines or swings, the ball rolls on the support disk to cause the support disk to vibrate. The vibration is taken out as an electric signal by the piezoelectric element and the electric signal inf...

A motion detector of the space surveillance type wherein an elongate box has parallel walls and an aperture opening toward sensors, and a pair of upwardly divergent reflectors is provided for at least one of the two sensing field planes, the reflectors making an angle of 20.degree. or less with each other.

A motion sensor has a ball of electrically conductive material in an annular ball race around which the ball can travel in response to motion of the sensor and electrical contacts spaced apart from one another around the ball race for electrical contact with the ball during such travel. A circuit responsive to electrical contact of the ball with the contacts detects the travel of the ball and, thus, motion of the sensor and a device is provided for selectively retaining the ball in an inoperativ...

This invention relates to motion simulators that are used to impart controlled movement to a rigid platform which may support the student station of a vehicle simulator, or the like. In particular, my invention relates to an improvement in the geometric arrangement of actuators and actuator pivot points on such devices to provide better motion fidelity, improved simultaneous excursion capability, and better adaptability in accommodating visual display systems. A unique feature of this invention ...

A rotary motion transformer particularly adapted to provide continuous rotary motion to a driven member in response to an intermittently rotated driving member is provided. The driven member and the driving member are oppositely poled magnetic permeable members disposed proximate to each other to provide a flux field therebetween. The driven rotary member is disposed in a viscous damping reservoir, the viscous damping reservoir effecting smooth and continuous rotation of the driven member.

A motion and position control for use in a system that includes a motor or other prime mover for moving a tool or other device and a sensor that generates a signal representative of the position of the device; the control comprises a sensor signal processor circuit producing a sequence of pulse position count signals. Each pulse position count signal, which identifies the position of the device at a given instant, is recorded in an up-down counter circuit that operates conjointly with a CPU to g...
