  • Patent number: 11054921
    Abstract: A stylus is provided, which includes a core body, an electrode disposed adjacent to the core body, a transmitter that sends a downlink signal including switch information SW1 using the electrode, and a controller that determines whether the stylus is in contact state with an operating surface or the stylus is in hover state. In the contact state, the controller controls the transmitter to send the switch information SW1 at a first bit rate. In the hover state, the controller controls the transmitter to send the switch information SW1 at a second bit rate smaller than the first bit rate. A technical advantage includes lowering the possibility of a failure to receive downlink signals when the stylus is in hover state, even though the stylus sends the downlink signals with the same intensity as when the stylus is in contact state.
