  • Patent number: 10976839
    Abstract: A stylus capable of bidirectionally communicating with a sensor controller includes a receiver that receives an uplink signal sent by the sensor controller, a controller that determines whether a signal having a predetermined waveform is to be continuously sent over a second time period or to be continuously sent over a first time period longer than the second time period, on the basis of the uplink signal, and a transmitter that continuously sends the signal having the predetermined waveform over the first time period or the second time period on the basis of the result of determination by the controller. As a result, the sensor controller can detect a burst signal from the stylus over a wide range in a sensor touch surface, to thereby reduce the possibility that the sensor controller may fail to detect the burst signal.

The signal processing section during operation in a first mode, while supplying a downlink signal DS1, obtained by modulating a pulse train signal with a pen pressure level P, to an electrode, determines whether it is necessary to switch to a second mode. The signal processing section during operation in the second mode, while supplying a downlink signal DS2, obtained by modulating a sine wave signal with the pen pressure level P, to the electrode, determines whether it is necessary to switch to the first mode. The signal processing section switches to operation in the second mode when determining that such is necessary, and switches to operation in the first mode when determining that such is necessary. The active stylus may be used with two position detection devices, one supporting only the first method and the other supporting only the second method.
