An apparatus for providing tactile feedback to an operator The apparatus Includes first and second magnetic assemblies having first and second magnets respectively The apparatus further includes a user input device, such as a trigger, a release cord, or a joystick that Is connected to at least one of the two assemblies and positions the first magnet proximate to the second magnet such that interaction occurs between the magnetic fields to generate a force that is exerted on the input device Tile force may be an opposing or resisting force that opposes movement of the user input such as resisting a triggering or releasing action in an interactive video game when the poles are of like polarity The magnetic assembly may be stationary, and the magnetic assembly may be connected to the user input device to be slid or positioned relative to the first magnet assembly.

A tubular linear generator comprises an elongate translator (12), containing a series of permanent magnets (13, 14....) and one or more annular coils (not shown) contained within and affixed to a ferromagnetic sleeve (31). Relative movement between the translator and armature causes the generation of electricity in the coils. The sleeve is contoured in terms of permeability around its circumference at one or both its ends, as shown at (32), in order to reduce cogging forces between the sleeve and the permanent magnets along the translator.

A system for transferring rotational motion includes a first rotational shaft (1A) extending along a first axial direction, and a second rotational shaft (1B) disposed along a second axial direction and spaced apart from the first rotational shaft (1A), wherein the first rotational shaft is magnetically coupled to the second rotational shaft via first members (2A/2B) and second members (3A/3B).

The device (1) comprises a frame (42) comprising a static magnetic pole (48), a movable member (44) relatively to the frame (42), the movable member (44) comprising a moving magnetic pole (46), the static magnetic pole (48) and the moving magnetic pole (46) being magnetically coupled in some position of the movable member (44), a piezosensitive element (50) so that the force due to the magnetic coupling between the moving magnetic pole (46) and the static magnetic pole (48) reacts on the piezosensitive element (50), and means (52, 54, 56, 58) for outputting an electric signal from the piezosensitive element (50), the signal being useful in determining the position and/or the speed and/or the direction of the movable member (44).
摘要:
A mechanical translator includes at least one magnet that is disposed on a substrate to carry a load and has a magnetic axis generally transverse to the substrate, establishing a magnetic field with maximum external density adjacent the substrate. An ultra low friction interface is obtained with ferrofluid bearings, such as a light mineral oil medium mixed with isoparaffinic acid, which establish a critical angle of displacement from a horizontal static position of less than 1 degree, and preferably less than 10 minutes. A controller of magnetic material can be placed on the opposite side of the substrate to control the movement of the magnets.

Disclosed are devices for influencing and/or controlling relative motion between members, such as vibration damping or absorbing devices, clutches and brakes. The devices comprise a magnet (18) on one member (14) and a field cooled superconductor (15) on the other member (10). The devices utilize the interaction of the magnetic field of the magnet as it moves through the pinned flux in the superconductor (15) to either influence or control relative motion.

The method allows to move, for example with a rotative motion, a member or a group of members by moving another member or group of members with a reciprocating rectilineal motion by means of the interaction between magnets (1, 2) or groups of magnets (1i, 2i) fixed to the said members or group of members. If the reciprocating rectilineal motion is obtained by connecting one of the two groups of magnets to the pistons of a reversed-star two stroke engine and to a mechanical energy restituting system (8), a high-efficiency propulsing means is realized, which is suitable for engine-traction, which does not need a crank-shaft, a lubricating system, water cooling system, alternator or torque converter, and is automatically switched off when the vehicle is not in motion. Its work-torque can be varied by varying the distance between said restituting system (8) and members (14) named cursors, connected to pistons (5). Easy and cheap to make, it causes little-pollution and is suitable even for using hydrogen as fuel. In which case, its pollution products are insignificant or equal to zero.

Electromechanical systems using magnetic fields to induce eddy currents and generate lift and thrust are described. A circumferential array of magnet elements which can be employed in the systems are illustrate. When the circumferential array rotates round its axis, it generates a travelling magnetic field moving alone its axis. The travelling magnetic field over a conductive substrate induces eddy currents in the conductive substrate, the eddy currents provide an opposing magnetic field to generate magnetic lift and thrust to support and drive the circumferential array.
