  • Patent number: 11946229
    Abstract: A work machine comprises an armrest and a user control operable by the user to control tool or machine functions when the user's arm rests on the armrest. An armrest sensor is configured to sense the presence of the user's arm and to disable the control when the user's arm is removed from the armrest. The control may be mounted on the armrest and the armrest movable between enabling and disabling positions by the weight of the user's arm. A seat sensor may be configured to disable the control when the user leaves the seated position.

  • Patent number: 9889874
    Abstract: A controller having a joystick which can be moved in three dimensions is disclosed. The joystick is connected by a Y (yaw) link which is, in turn, connected to a P (pitch) link, which is, in turn connected to an R (roll) link. The R link is rotatable about a fixed-position mounting base. Alternately, the joystick is connected by an R (roll) link which is, in turn, connected to a P (pitch) link, which is, in turn connected to an Y (yaw) link. The Y link is rotatable about a fixed-position mounting base. In either of these manners, one can rotate a joystick around any of three axes. When used to control a vehicle, rotation around the yaw and roll axes can steer (with one being more fine-tuned steering), and rotation around the pitch axis can control acceleration and deceleration.

  • Patent number: 7740207
    Abstract: An aircraft flight control system advantageously is provided with a control rod which is spline-connected to a bearing assembly so as to permit simultaneous independent longitudinal and rotational movements of the control rod while isolating such movements from one another (e.g., so as to allow operative interconnection to an aircraft's aileron and elevator control surfaces). Thus, the control rod is moveable in longitudinal and rotational directions relative to a longitudinal axis of the control rod in response to pitch and roll command inputs, respectively. The control rod is splined operatively to the bearing assembly so as to allow for independent simultaneous longitudinal and rotational movements of the control rod relative to the longitudinal axis thereof to thereby allow the command inputs to be transferred to the aircraft's respective flight control surfaces.

  • Patent number: 6347770
    Abstract: A dual-seat control system for an aircraft provides an upright mounted at one end to pivot by actuation of a user near the other end. Cross beams extend from the upper end of the upright to positions in front of each user. The cross beams each carry a handle at an outboard end by which an operator can move the upright as a control stick in either a pitch-control direction, or a roll-control direction. The cross beams are free to move in one degree of freedom with respect to the upright, and are fixed in the other degree of freedom. Typically, the handle is attached in a manner to move in rigid body motion with respect to the upright in a pitch-control direction, while being free to move in a plane defined by the cross beam and upright at will, according to the desires of an operator. In certain embodiments, the handle may be required to be parallel to the upright in all positions, from a lower stowed position to an upper deployed position.
