摘要： A knob for an input device includes a knob housing being rotatable on an axis, a shaft extending from the knob housing along the axis, a ratchet wheel axially coupled to the shaft with a toothed perimeter, and a ratchet arm to couple to the toothed perimeter of the ratchet wheel when the ratchet arm is engaged such that a ratcheted rotation occurs when the knob is rotated, and decouple from the toothed perimeter of the ratchet wheel when the ratchet arm is disengaged. The knob can further include a resistance wheel axially coupled to the shaft with a substantially smooth perimeter, and a resistance arm to couple to the smooth perimeter of the resistance wheel when the resistance arm is engaged such that a friction is provided when the knob is rotated, and decouple from the smooth perimeter of the resistance wheel when the resistance arm is disengaged.

摘要： In certain embodiments, an electronic input device includes a knob assembly defining an annular cavity and including a magnetically attractable armature. The electronic input device also includes a ratchet assembly disposed within the annular cavity and includes a ring magnet. The electronic input device includes a clutch mechanism that has a friction disc assembly, and an electromagnet configured to generate a magnetic field that shifts the friction disc assembly between a first position in which the friction disc assembly prevents rotation of the ratchet assembly and a second position in which the ratchet assembly is free to rotate with the knob assembly. The ring magnet of the ratchet assembly interacts with the magnetically attractable armature to generate a ratcheting feedback in response to rotation of the knob assembly when the friction disc assembly is in the first position.

摘要： An input device including a housing and a depressible key plate disposed thereon. The key plate includes a front user-accessible portion, a pivot support portion, and a rear portion. A shaft is disposed in the pivot support portion, where the key plate rotates with respect to the shaft. A force sensor is disposed in the housing and in contact with a bottom surface of the front portion of the key plate, and activates in response to receiving a predetermined force by the bottom surface of the front portion of the key plate. The depressible key plate depresses in response to receiving a predetermined depression force on the top surface. A biasing mechanism is disposed in the housing and in contact with the bottom surface of the rear portion of the key plate to provide an upward force tuned to be substantially equal to the predetermined depression force.

摘要： In certain embodiments, an input device includes a chassis and a depressible actuator disposed on the chassis that, when depressed, generates and sends a control signal to a processor, where the actuator is coupleable to a removable button cover that provides user-access to activate the actuator, and a removable blank cover to prevent user access to activate the actuator. The button cover and blank cover can be separate from the chassis and may directly attach to the actuator. The input device can further include a second depressible actuator disposed on the chassis that, when depressed, generates and sends a second control signal to the processor, where the second actuator is coupleable to the button cover and the blank cover.
