An optical device housing has a post rotatably extending therefrom and a sleeve fixedly extending therefrom. The sleeve is disposed about the post and a knob is connected to the post. A nut rotatably engages with the sleeve and is configured to rotate with the knob. An adjustment screw is threadably engaged with the nut and engages with the knob so as to rotate with the knob. Rotation of the adjustment screw about a screw axis increases a frictional resistance between the nut and the sleeve.

An electronic control system for controlling movement of a work machine is disclosed. The control system may include a first and a second joystick, each of the first and second joysticks configured to move between a neutral and an operational position. Moreover a first and second resistive device may be operatively coupled to the first and second joysticks respectively. The first and second resistive devices may be configured to generate a resistive force to selectively retain the first and second joysticks in the operational position. Additionally, the control system may include a controller in communication with the first and second joysticks and the first and second resistive devices. The controller may transmit a first and second resistive force signal to activate one of the first and second resistive devices to generate the resistive force such that one of the first and second joysticks is retained in the operational position.

An active inceptor apparatus and method for operating a machine. The apparatus comprises a stick member having a grip portion, the stick member being pivotably mounted relative to a housing. It further comprises a position sensor responsive to, and for generating signals indicative of, stick member position. A force sensor is provided on the stick member responsive to, and for generating signals indicative of, force applied to the stick by a user. The apparatus also includes a control unit operable to receive the position and force signals from the position and force sensors respectively. The control unit is operable to process the signals according to a predetermined relationship to determine a value FD indicative of force applied to the stick member relative to displacement of the stick member. The control unit is also operable to generate machine control signals as a function of position signals and force signals in dependence upon the value FD, for communication to the machine.

In order to provide a fail-safe operating mode during a transition between an autonomous steering mode and a driver-controlled steering mode in an emergency situation, a steering system comprises a steering shaft, a brake mechanism movable between an released position and a engaged position for angularly locking the steering shaft, and an override such that a non-destructive external torque applied to the steering shaft above a given threshold when the brake mechanism is in the engaged position results in a rotation of the steering shaft.

An adjustment apparatus for adjusting a setting of a sighting device, such as a riflescope or telescope, includes an adjustment knob operatively coupled to an adjustment mechanism, where rotation of the adjustment knob about a rotational axis drives the adjustment mechanism to adjust the setting of the sighting device. The adjustment apparatus further includes a lock mechanism including a first lock element fixed relative to the sighting device and a second lock element selectively movable relative to the first lock element. When the lock elements engage one another, the adjustment knob is in a locked position and restrained from rotating about the rotational axis. The adjustment apparatus may further include a lock-release mechanism operable to disengage the lock elements and allow the adjustment knob to rotate about the rotational axis.

The invention relates to an activation device (1) for a parking brake with a parking brake lever (2) swivel-mounted on a bearing block (3) and with a blocking device comprised of a pawl (13) on the parking brake lever (2) and a locking segment (12) on the bearing block (3). The parking brake lever (2) is fixed in place in a swivel position via the engagement of the pawl (13) with the locking segment (12). The swivel position of the parking brake lever (2) is transmitted via a transmission element to the parking brake and with a transfer device in or on the parking brake lever (2). The engagement of the pawl (13) with the locking segment (12) is released by actuating the transfer device. To form a swivel bearing, a shaft is provided to which a holder (7) for the transmission element and the parking brake lever (2) can be affixed in different rotational positions. As an alternative, or in addition, a linear movement of the pawl (13) is brought about by means of the transfer device.

A brake lever assembly includes a hood body and a brake lever movably coupled to the hood body. The hood body defines an internal cavity containing a transducer coupled to the brake lever such that an output of the transducer corresponds to a position of the brake lever. The transducer output may then be used to control a resistance element of an exercise device (e.g., a stationary bicycle) to simulate application of braking force by a rider. The transducer may be a linear potentiometer disposed within the cavity and coupled to a plunger assembly. The plunger assembly may include a plunger coupled to each of the linear potentiometer and the brake lever such that movement of the brake lever moves the linear potentiometer and varies the output of the potentiometer. The brake lever assembly may include additional buttons for upshifting, downshifting, and/or other controls.
