Abstract
An information handling system may include a processor; a data storage device; a power management unit (PMU); a spring-back force adjustable pointing device operatively coupled to communication with the processor, including: a pointing device housing; a key plate operatively coupled to the pointing device housing at a key plate hinge; a first magnet operatively coupled to the key plate; and a second magnet operatively coupled to an opposing magnet adjustment device to adjust the position of the second magnet relative to the first magnet, wherein the first magnet and second magnet have repelling poles facing each other to assist spring-back of the key plate when opposing magnets fields interact.
Claims20
An information handling system, comprising:
- a processor;
- a data storage device;
- a power management unit (PMU);
- a spring-back force adjustable pointing device operatively coupled to communicate with the processor to control a cursor, including:
- a pointing device housing;
- a key plate operatively coupled in the pointing device housing at a key plate hinge to receive a press from a user's finger;
- a first magnet operatively coupled to the key plate;
- and
- a second magnet operatively coupled to an opposing magnet adjustment device selected from a magnetic arm housing the second magnet operatively coupled to a slide knob to interface with a lifter to lift the second magnet relative to the first magnet or a rotation knob to rotate the barrel housing the second magnet to adjust the position of the second magnet relative to the first magnet, wherein the first magnet and second magnet have repelling poles facing each other to assist spring-back of the key plate when opposing magnets fields interact and the slide knob and the lifter or the barrel make an adjustment to second magnet location and the force required from a press from a user's finger and speed of spring-back of the key plate.
A spring-back force adjustable pointing device, comprising:
- a pointing device housing;
- a key plate operatively coupled to the pointing device housing at a key plate hinge;
- a first magnet operatively coupled to the key plate;
- and
- a second magnet operatively coupled to an opposing magnet adjustment device to adjust the position of the second magnet relative to the first magnet, wherein the first magnet and second magnet have repelling poles facing each other and to assist spring-back of the keyplate when opposing magnetic fields interact;
- the opposing magnet adjustment device comprising:
- a magnet arm to house the second magnet;
- and
- a slide knob to interface a lifter operatively coupled to the slide knob with the magnet arm to selectively adjust the distance between the second magnet and the first magnet to adjust the magnetic field levels during actuation of the key plate.
A spring-back force adjustable pointing device, comprising:
- a pointing device housing;
- a key plate operatively coupled to the pointing device housing at a key plate hinge;
- a first magnet operatively coupled to the key plate;
- and
- a second magnet operatively coupled to an opposing magnet adjustment device to adjust the position of the second magnet relative to the first magnet, wherein the first magnet and second magnet have repelling poles facing each other to assist spring-back of the keyplate when opposing magnetic fields interact;
- the opposing magnet adjustment device further comprising:
- a barrel housing to house the second magnet and one or more additional magnets, the second magnet and one or more additional magnets having different magnetic field strengths;
- and
- a rotation knob to rotate the barrel housing to operatively change the position of the second magnet relative to the first magnet to operatively engage the magnetic field of one of the one or more additional magnets with the magnetic field of the first magnet and operatively disengage the magnetic field of the second magnet from the magnetic field of the first magnet.
