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.

A device for the alphanumeric labeling of printed products comprises a shaft mounted in a frame, and around which shaft at least one wheel-shaped or ring-shaped labeling tool is rotatably mounted, which tool carries a number of alphanumeric characters, one behind the other, on its outer circumference. A drive motor, in the form of, for example, a stepper motor, is provided and by which the labeling tool can be rotated around the shaft. The drive motor is linked for signals transmission to one of a data processing and a data storage of a control device, in which an assignment specification between the working positions of the alphanumeric characters or the fields carrying the alphanumeric characters, and step numbers of the stepper motor, is provided. The drive motor is or can be controlled by the control device in terms of a number of steps to be traveled, using this provided assignment specification, to move an alphanumeric character to be printed or the relevant field into a working position.

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.

A knob for an input device may include a knob housing being rotatable on an axis, a shaft coupled to and extending from the knob housing along the axis, a ratchet wheel axially coupled to the shaft and including a toothed perimeter, and a resistance wheel axially coupled to the shaft and including a smooth perimeter, where the ratchet wheel and the resistance wheel are rotatable on the axis in correspondence with a rotation of the knob housing. A biasing mechanism provides a force on its first end to cause a roller to engage with the toothed perimeter of the ratchet wheel such that a ratcheted rotation occurs when the knob housing is rotated, and further provides a force on its second end to cause the second end to engage with the smooth perimeter of the resistance wheel such that a friction is provided when the knob housing is rotated.

A system and method for controlling friction between a mouse and the surface upon which it is placed. Reduction of friction can be accomplished in several ways, including: making the feet of the mouse from various different materials, creating layers of air between the mouse and the surface, creating beveled edges for the feet of mouse, etc. In one embodiment, the feet of the mouse are made of a piezo-electric layer bonded to another layer made of a different material. Exciting the piezo-electric layer at certain frequencies makes the two layers shrink and expand differently, thus creating oscillations of the feet. In yet another embodiment, portions of the mouse feet are made of different materials with different coefficients of friction. These different portions of the feet can be pressed down onto the surface with varying amounts of pressure, thus altering the friction.

A key module for a keyboard includes a key having a guiding plunger, and a key housing having a set of walls with an opening formed by the set of walls. The opening formed by the set of walls is configured to receive the guiding plunger. The set of walls includes at least eight guiding surfaces configured to contact the guiding plunger. The guiding plunger is configured to contact the eight guiding surfaces as the guiding plunger moves up and down in the opening.
