The present invention relates to a force application device for a control stick of an aircraft comprising a shaft and a control lever configured to rotate the shaft about a first axis, the device comprising: a magnetic brake comprising a braking part configured to be connected to the shaft, and a volume containing a rheological fluid in contact with the braking part, of variable shear resistance as a function of a magnetic field applied to the rheological fluid, a force feedback motor configured to exert a resistive force opposing the rotation of the shaft about the first axis, a motor power source, a movable magnetic element biased towards a position close to the magnetic brake, and distancing means configured to maintain the movable magnetic element in a position away from the magnetic brake, when such distancing means are powered by the power source.

A mechanical controller provides four-axis control of a vehicle's position and movement. For example, the controller provides control of a vehicle's operations through a lateral axis, longitudinal axis, directional axis, and a grip axis (e.g., operating a thumbwheel of the mechanical controller that provides additional control inputs to the vehicle). The mechanical controller can provide independent force feel mechanisms in each of the lateral, longitudinal, and directional axes of movement. Additionally, the mechanical controller may provide a redundant force feel mechanism (e.g., for increased safety). For example, redundant springs and dampers may be incorporated in each axis's force feel mechanism. The mechanical controller may include a plunger and spring assembly to provide a force feel mechanism in the lateral and longitudinal axes. In addition to this spring force, surfaces of a contact region between the plunger and a plunger actuating plate may be shaped to produce force feel characteristics.

A rotating electric machine includes a rotor and a wound stator. The wound stator has a stator shaft, wherein the stator coils are inserted in the rotor, and the stator shaft is inserted in the center of the rotor. At least one angular position sensor of the rotor is inserted in the center of the space delimited by the stator shaft and the rotor.

In the hydraulic excavator, the control unit outputs the drive signals, which gives the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device to the work implement operating lever, the right work implement operating lever and the traveling lever, to the drive section. The control section outputs the control signals based on the motion of the left work implement operating lever the right work implement operating lever or the traveling lever operated by the operator when the motion of the left work implement operating lever, the right work implement operating lever or the traveling lever operated by the operator is different from the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device.

A multidirectional input apparatus includes a housing including an opening portion; an operation member including an operation portion provided outside the housing and configured to be operated, and a shaft portion extending from the operation portion and inserted into the opening portion, the operation member being configured to receive an operation to be tilted with respect to the housing and an operation to be pushed into the housing; and a cover member that covers a portion surrounding the shaft portion, the cover member being configured to come into contact with the housing when the operation of pushing the operation member is performed.

A remote driving device (100) includes an operation lever (1) to be operated based on an operation command signal, and a first operation mechanism (30) which tilts the operation lever (1). The first operation mechanism (30) includes a first actuator (31) which generates a driving force to tilt the operation lever (1) based on the operation command signal, a first transmission device (41) which transmits the driving force of the first actuator (31), a first detector (61) which detects a tilting amount of the operation lever (1), and a first drive shaft (51). On the first drive shaft (51), a first rotation output part (52) is provided, and the first drive shaft rotates with the tilting of the operation lever (1). The first detector (61) detects the tilting amount of the operation lever (1) via the first rotation output part (52).

A control device consists of a handle with buttons and an on/off trigger, a sphere, an optical, electromagnetic or laser sensor, a fixed base with a half-sphere, and a part situated below said base. The device is designed to simulate a response from working mechanisms and can be used for controlling different manned and unmanned devices, air, land and underwater devices, as well as for working with computer equipment and also for controlling spacecraft.

A thumbstick for a user input device comprises an adjustable tensioning mechanism configured to modify a tilt tension of a tiltable post. The tiltable post is operable to output a control signal based on a position of the tiltable post relative to a default position. The thumbstick comprises a cap with a cylindrical stem that defines a cavity. An engagement body is located within the cavity and contacts an engagement surface of the adjustable tensioning mechanism. The engagement body includes a cam surface disposed around an axis of the tiltable post. An adjustment body within the cavity of the stem comprises a follower that contacts the cam surface. The follower is configured to traverse the cam surface when the cap is rotated to thereby translate the engagement body along the axis of the tiltable post and adjust the tilt tension of the tiltable post.

A thumbstick for a user input device comprises an adjustable tensioning mechanism configured to modify a tilt tension of a tiltable post. The thumbstick comprises a cap with a cylindrical stem that defines a first cavity. Abase is moveable with the tiltable post and comprises a cylindrical portion extending into the first cavity. The cylindrical portion defines a second cavity and comprises a protuberance projecting into the second cavity. An adjustment body within the second cavity comprises a recessed slot and a contacting surface at a distal end. The slot is configured to engage the protuberance to adjust the tilt tension of the tiltable post.

A pointing device includes: a substrate; an operation member that is provided tiltably with respect to the substrate, and includes a protrusion protruded from one of an inner wall and an outer wall; and a rotation member that is provided rotatably on the substrate, and includes a hole which the protrusion enters when the rotation member overlaps the operation member; wherein the rotation member rotates in conjunction with the operation member when the protrusion contacts an edge of the hole according to rotation of the operation member, wherein the hole is formed in a range in which the protrusion is movable by tilt of the operation member.
