Abstract
A computer mouse can include a scroll wheel assembly that includes a scroll wheel rotatable about a scroll wheel axis; and a motor assembly that includes a rotor aligned with the scroll wheel axis and operatively coupled to the scroll wheel.
Claims18
A computer mouse comprising:
- a scroll wheel assembly that comprises a scroll wheel rotatable about a scroll wheel axis;
- a motor assembly that comprises a rotor aligned with the scroll wheel axis and operatively coupled to the scroll wheel, wherein the motor assembly comprises a brushless DC motor;
- and
- motor control circuitry for control of the brushless DC motor, wherein the motor control circuitry senses a stall condition as input responsive to application of force to the scroll wheel that overcomes a torque of the brushless DC motor, wherein the motor control circuitry controls power to the brushless DC motor responsive to a sense of the stall condition to reduce risk of overheating, and wherein the motor control circuitry comprises a haptic feedback mode to generate haptic feedback via the scroll wheel via application of force to the rotor by the brushless DC motor.

A method comprising:
- receiving an utterance by a microphone of a computer mouse;
- decoding the utterance;
- and
- issuing a control signal based on the decoding, wherein the control signal comprises a motor control signal that controls a motor assembly of the computer mouse, wherein the motor assembly comprises a rotor operative coupled to a scroll wheel of the computer mouse.
1 more element
A computer mouse comprising:
- a scroll wheel assembly that comprises a scroll wheel rotatable about a scroll wheel axis;
- a motor assembly that comprises a rotor aligned with the scroll wheel axis and operatively coupled to the scroll wheel;
- and
- voice recognition circuitry that comprises one or more microphones, wherein the voice recognition circuitry generates motor control commands responsive to decoded utterances, wherein the utterances are received by at least one of the one or more microphones.
1 more element
A method comprising:
- performing a motorized scroll wheel action using a brushless DC motor of a computer mouse coupled to a scroll wheel of the computer mouse for rotation of the scroll wheel;
- sensing a stall condition of the brushless DC motor as input, wherein the stall condition is responsive to application of force to the scroll wheel by a finger;
- responsive to the sensing of the stall condition, controlling power to the brushless DC motor to reduce risk of overheating;
- and
- based on the input, transmitting a signal to an electronic device to stop performing an action.
