  • Patent number: 10877580
    Abstract: An active stylus includes a signal processing section. 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.

  • Patent number: 10878217
    Abstract: Techniques for communicating particular information from a user to a touch screen device by way of a touch event is provided. Sensors that are operatively coupled to a sensing device sense an input from the user which conveys particular information. This input is then converted by the sensing device into another signal called the sensing device signal which is then transmitted from the sensing device to the user's skin. Then a second set of sensors that are operatively coupled to a touch device receive a user-touch signal that is transmitted from the user's body. The user-touch signal is based, at least in part on the sensing device signal. The touch device then decodes the user-touch signal to determine the location of the touch event on the touch device and sensing device signal embedded in the user-touch signal to extract the particular information related to the user.
