Patent ID: 11972066
Assignee: DELL PRODUCTS L.P.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. An information handling system comprising:
a processor operable to execute instructions to process information;
a memory interfaced with the processor and operable to store the information and instructions;
a display interfaced with the processor and operable to present the information as visual images;
a mouse interfaced with the processor, the mouse having a position sensor operable to detect movement for cursor position control of a cursor presented at the display, the mouse having a scroll wheel exposed at an upper surface, the scroll wheel rotating with a tactile response created by magnetic attraction between a geared wheel coupled to the scroll wheel and a first magnet disposed proximate the geared wheel, the first magnet having a magnetic field focused towards the geared wheel;
a magnetic focus lens coupled to the first magnet and having ferromagnetic material configured to direct the magnetic field of the first magnet at the geared wheel, the magnetic focus lens comprising a first arm directed at the geared wheel at a first location and focusing the first magnet north pole and a second arm directed at the geared wheel at a second location and focusing the first magnet south pole;
a support arm;
a second magnet coupled to the support arm, the second magnet having a polarity opposite the first magnet; and
a motor coupled to the support arm to selectively move the second magnet proximate the first magnet thereby canceling the magnetic attraction of the first magnet to the geared wheel.
