A sleeve or case for a mobile device, such as a smartphone or tablet or other types of hand-held device or mobile smart device, has a sleeve part for at least partially enclosing the mobile device and an input device arranged in the sleeve part for controlling the mobile device which can be received in the sleeve part. The input device includes a movable control element and a magnetorheological brake. Any movement of the control element can be selectively damped by way of the magnetorheological brake.

An apparatus for a crank handle of a landing gear. The crank handle comprising an assembly with a rotating arm, a mounting end, a handle arm, and a handle grip. The handle grip mounted to the handle arm. The handle grip rotatable about the handle arm at a handle end of the crank handle assembly.

An input device includes: a rotating member that rotates about a predetermined rotation axis; and a mover that includes a protrusion protruding toward an inner peripheral surface of the rotating member and moves in a direction different from a rotation direction of the rotating member along with rotation of the rotating member. The protrusion protrudes toward an inner peripheral surface of the rotating member. The rotating member includes a first projection and a second projection that project from the inner peripheral surface toward the mover. The protrusion of the mover is inclined with respect to the predetermined rotation axis and disposed between the first projection and the second projection.

An input device includes a fixed unit, a rotary member rotatably supported by the fixed unit, a rotation-detecting unit that detects a rotation angle of the rotary member, a brake-applying unit that applies a braking force to the rotary member, a torque-applying unit that applies a driving torque to the rotary member, and a control unit that controls the brake-applying unit and the torque-applying unit. The brake-applying unit includes magnetorheological fluid, a brake-applying coil that applies a magnetic field to the magnetorheological fluid, a shaft to which braking torque that changes with viscosity of the magnetorheological fluid is applied, and a transmission gear provided on the shaft and that is in mesh with a gear provided on the rotary member. The shaft is positioned on an outer side with respect to the rotary member in a radial direction of the rotary member.

A stem shaft handle has a handle body and a gearless ratchet assembly having a threaded cylindrical drive head disposed within an inner cavity defined by the handle body. The threaded cylindrical drive head connects the gearless ratchet assembly to a chuck assembly having a cylindrical chuck body concentrically disposed within an outer sleeve. The cylindrical chuck body has an outer surface which closely aligns with the outer sleeve in a key-and-lock style geometric alignment. The outer surface of the cylindrical chuck body has at least one biasing locking protuberance, and the outer sleeve defines adjacent notches around at least one nodule geometrically configured to operatively engage the at least one biasing locking protuberance in a locking arrangement. Upon a rotation of the stem shaft handle relative to the outer sleeve, the outer sleeve impinges the biasing locking protuberance until the biasing locking protuberance snaps into the locking arrangement between.

An operation device has a first displacement portion that is displaceable by being operated by an occupant of a vehicle, and a second displacement portion that is supported at the first displacement portion and that is displaceable with respect to the first displacement portion by being operated by an occupant of the vehicle. Further, the operation device has a first locking portion and a second locking portion that, at a time when a mode of the vehicle is a first mode, permit displacement of the first displacement portion and restrict displacement of the second displacement portion with respect to the first displacement portion, and, at a time when the mode of the vehicle is a second mode, restrict displacement of the first displacement portion and permit displacement of the second displacement portion with respect to the first displacement portion.

A control device may be configured to control an amount of power delivered to one or more electrical loads and provide various feedback associated with the control device and/or the electrical loads. The control device may be a wall-mounted device or a battery-powered remote control device. The feedback may indicate the amount of power delivered to the one or more electrical loads. The feedback may also indicate a low battery condition. The control device may include a light bar and/or one or more indicator lights for providing the feedback.
