A peripheral device may include a body. The device may include a scroll wheel rotatably coupled with the body. The scroll wheel may include a ferromagnetic rotor. The rotor may be generally annular and may define an open interior. The rotor may define a first plurality of teeth arranged about a periphery of the open interior. The device may include a stator disposed within the open interior. The stator may define a second plurality of teeth that are alignable with the first plurality of teeth. The stator may include a plurality of electro-permanent magnets. Each of the electro-permanent magnets may be disposed within a conductive coil. The device may include a position sensor that is configured to detect an angular position of the rotor. The device may include control circuitry that controls delivery of current to the electro-permanent magnets of the stator to controls a speed of the scroll wheel.

Motorized scroll wheel for an input device

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.

Input device including a ratchet system with an electromagnetic actuator

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.

Input device including a mechanical ratchet system with smart shift

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.

Mechanical ratchet system for a knob

Input devices having a thin profile and good comfort and feel are disclosed. In embodiments, an input device includes a sensor layer configured to effectuate a key press upon application of an activation force, and a collapsible layer coupled to the sensor layer. The collapsible layer may be configured to collapse in response to a collapsing force that is substantially equal to the activation force. When the collapsible layer collapses, the sensor layer may simultaneously effectuate the key press in response to application of the collapsing force.

Solid state input device

A method includes placing an input device in a passive mode of operation and periodically monitoring a displacement sensor of the input device, receiving an indication of displacement from the displacement sensor, and placing the input device in an active mode of operation characterized by a power consumption level. The method also includes determining a passing of a predetermined time period since receiving the indication of displacement, placing the input device in a second active mode of operation characterized by a second power consumption level less than the power consumption level, and periodically monitoring one or more of a plurality of touch sensors. The method further includes receiving an indication of input from the one or more of the plurality of touch sensors and placing the input device in the active mode of operation.

Method and system for power conservation in a multi-zone input device

An input device includes a housing for supporting a user's hand and a displacement sensor, mounted in the housing, for providing a displacement signal. The input device also includes a first portion of the housing operable to receive a first digit of the user and a first solid-state touch sensor disposed in the first portion and operable to detect movement of the first digit along the first portion. The input device further includes a second portion on the housing operable to receive a second digit of the user and a second solid-state touch sensor disposed in the second portion and operable to detect movement of the second digit along the second portion.

Input device with multiple touch-sensitive zones

A method of operating an input device in conjunction with a host device includes determining that the input device is in a stationary state and receiving a first signal from a first sense zone of the input device. The method also includes determining an input command based on determining that the input device is in the stationary state and the first signal and transmitting a signal associated with the input command from the input device to the host device.

Method of operating a multi-zone input device

A touch sensor system includes a touch controller having a first connector and a second connector and multiple sensor zones. The touch sensor system also includes a plurality of drive lines connected to the first connector of the touch controller and to the multiple sensor zones and a plurality of sets of sense lines connected to the second connector of the touch controller. Each set of the plurality of sets of sense lines is connected to one of the multiple sensor zones.
