Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.

The present invention relates to a device in a vehicle damper which comprises a damping medium-filled damper body (2), in which an element (5, 5′) forming a seal against the damper body divides the damper body into two chambers (2a, 2b). A microprocessor control unit (SU) is coupled to one or more valve and connecting arrangements (4a, 4b, 4c), comprising at least one valve and a number of flow ducts. Respective valves and flow ducts of the valve and connecting arrangement (4a, 4b, 4c) are coupled both to respective damper chambers (2a, 2b) and a pressurizing element (3) common to both of the chambers, so that even in the chamber in which a low pressure prevails there is a positive pressure acting at all times. The valve and connecting arrangements (4a, 4b) comprise a continuously electrically controlled main valve (CES), a non-return valve (SV) and one or more bleed valves (BV, 10a, 10b), the flow through the bleed valve(s) (BV, 10a, 10b) being adjustable separately from the electrically controlled main valve (CES). In the case of small strokes or slow movements the damping medium flows via the bleed valve (BV, 10a, 10b) through one or more separate leakage flow ducts. By locating the leakage flow duct(s) parallel to the valve and connecting arrangement (4a, 4b, 4c) the low-speed damping can be adjusted separately from the high-speed damping. The electrically adjustable main valve (CES) can therefore be adjusted to the correct damping characteristic whilst the damper is set up for small strokes and slow movements.

Tools for controlling cameras (and other objects), using an input device. Some such tools may establish a threshold, above which the input from the input device is fed directly to the object being controlled, and below which the input signal is processed to provide smoother operation. This can allow for direct control over a camera (or other object) in large movements but still allow for smooth, controlled movements when slower movement is desired.

A landing gear system for an aircraft includes a retractable landing gear assembly, a hydraulic actuator for actuating movement part, for example a bogie of the landing gear assembly, and an accumulator associated with the actuator. The accumulator comprises a volume of pressurised gas separated from hydraulic fluid by a separator piston. Travel of the separator piston beyond a certain position is indicative of a fault. The accumulator includes a snubbing device that acts to slow movement of the separator piston beyond that position. A monitoring system measures the time taken for the movement of the landing gear part effected by the hydraulic actuator. If the measured time is longer than a threshold time, that is indicative of a possible fault in the accumulator, that might, without the snubbing, remain undetected and/or hidden from view.
