A gimbal support that senses rotational displacement and provides haptic feedback in one, two or three dimensions of a manually-operated control member used to generate control inputs using a single hand while also limiting cross-coupling.

The present invention relates to a force application device for a control stick of an aircraft, wherein the control stick comprises a control lever (1) rotating a shaft (A1) about a first axis (A), the device comprising a magnetic brake (5a) which comprises a magnetisable element (50a) mounted on the shaft and a magnetic transmitter (51a) which is opposite the magnetisable element and free to rotate about the first axis relative to the magnetisable element, the magnetic transmitter having an activated state in which the magnetic transmitter is supplied with current and generates a magnetic field in a volume occupied by the magnetisable element, and a deactivated state in which the magnetic transmitter is not supplied with current and does not generate a magnetic field, so as to prevent the magnetisable element from rotating about the shaft relative to the magnetic transmitter.

A work vehicle includes a vehicle main body, a work implement attached to the vehicle main body, an operating lever configured to operate the work implement, an imparting section configured to impart force to the operating lever, an acceleration detection section configured to detect acceleration of the vehicle main body, and a control section configured to control the imparting section to automatically adjust a magnitude of the force imparted to the operating lever based on the acceleration detected by the acceleration detection section.

The present disclosure relates generally to control systems, and in particular apparatus, methods, and systems for controlling flights remotely or onboard the vehicle. More specifically, the present disclosure describes embodiments of a control system that allows a user to control the motion of a target in or along one or more degrees of freedom using a single controller. The control system described herein also include mechanisms that permit the conversion of user intent into discrete 3-D motions with tactile feedback relative to the null command.

The invention relates to a force application device for a control stick of an aircraft, said control stick comprising a control lever that is connected to at least one motor comprising a drive shaft that can be rotated about an axis, the force application device comprising: a first pin connected to the shaft, a housing, an electromagnet, a movable actuator comprising a magnetic material, a coupling device comprising an input gear connected to the housing and an output gear comprising a second pin, and means for clamping the first pin and the second pin which comprise a first tooth and a second tooth, said device having an operating configuration in which the electromagnet is active and the output gear is positioned at a distance from the input gear, and a blocking configuration in which the electromagnet is inactive and the gears are meshed.

A joystick for controlling a machine comprising; a handle assembly allowed to rotate around a central axis extending along a longitudinal direction of the joystick, a control portion having a casing in which a lower circuit with a lower sensor is provided and a control lever attached to the said casing so as to move pivotally about at a pivot axis which extends perpendicularly to the longitudinal axis of the control lever. Advantageously, said control lever having at least one embedded lower magnet is manufactured from plastic by the injection molding; said control lever comprises: at least one pivotal protrusion extending outwardly from the control lever for bearing in a housing of a casing; said pivotal protrusion forming a monolithic structure with the control lever by said injection molding and in that said lower magnet is embedded within the pivotal protrusion to be in the proximity of said lower circuit.

A joystick for controlling a machine in multi-axes includes a control portion having a body in which at least one circuit board having at least one sensor is provided; a top portion having a flexible boot forming at least partly an outer periphery of the top portion provided on the control portion; a control arm mounted on a pivotal member for pivotal movement relative to the body; wherein said control arm is made of plastic in an injection-molding operation and has an overmolded magnetic member suitable to interact with the sensor, said magnetic member provided in the proximity of the circuit board wherein said control arm has a connection portion such that said flexible boot is attached to the control arm from said connection portion. Thereby usage of the overmolded control arm which made of plastic provides sensitivity, production quality and additionally, thriving resistance to vibration.

An inductive joystick may include a control structure including an elongate member movable along at least one direction substantially perpendicular to its length; and a position sensing assembly including a printed circuit board having at least one surface arranged adjacent to the control structure and at least one metal dial arranged over the at least one surface. The at least one surface may be substantially parallel with the elongate member's length and with the at least one direction, and may be provided with at least one transmitter coil and at least one receiver coil. In use, the transmitter coil(s) may induce signal(s) in the receiver coil(s) and the metal dial(s) may interfere with the induction. Moving the elongate member may cause relative movement between the surface(s) and the metal dial(s) which may vary the induced signal(s) based on a position of the metal dial(s).

A reading device is for reading a positional relationship between a first component and a second component. The first component has an optical sensor and the second component has a collimator configured for directing a light beam at the optical sensor. A method is for reading a positional relationship between two components, the method including passing light through a collimator in a first component towards an optical sensor in a second component, reading the position of the light beam from the collimator on the optical sensor, and calculating the positional relationship between the first and second components from the position of the light beam on the optical sensor.
