  • Patent number: 11714500
    Abstract: A method to be performed by a sensor controller that periodically transmits an uplink signal, and by a stylus that, upon receiving the uplink signal, determines a transmission and reception schedule for a downlink signal and the uplink signal on the basis of the reception timing of the uplink signal. The method includes executing, by the stylus, an uplink signal receiving operation for a first predetermined period of time according to the transmission and reception schedule. The method includes, responsive to the uplink signal not received through the receiving operation and expiration of the first predetermined period of time, continuing, by the stylus, the uplink signal receiving operation for a second predetermined period of time, instead of transmitting the downlink signal according to the transmission and reception schedule.

  • Publication number: 20230146504
    Abstract: Provided are a pen state detection circuit, a pen state detection system, and a pen state detection method that can improve estimation accuracy for a pen state in an electronic pen including at least one electrode. A pen state detection circuit acquires, from a touch sensor, a first signal distribution indicating a change in capacitance associated with approach of a first electrode and uses a machine learning estimator to estimate an instruction position or an inclination angle of an electronic pen from first feature values related to the first signal distribution. The first feature values include first local feature values related to a first local distribution corresponding to sensor electrodes in a number fewer than the number of arranged sensor electrodes exhibiting the first signal distribution.

  • Publication number: 20230011324
    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.

  • Publication number: 20220416614
    Abstract: Air circulation passages connect an accommodation space of an electronic control unit to the outside to circulate air to buffer internal pressure fluctuations. The accommodation space side of the air circulation passages is formed as a divided air circulation passage with a plurality of passages, a cooling object member is arranged to come in thermal contact with air flowing through the divided air circulation passage, and the total cross-sectional area of the divided air circulation passage is smaller than the cross-sectional area of the air circulation passages that are not divided. Because the accommodation space of the electronic control unit is connected to the outside, internal pressure fluctuations can be buffered, and increasing the flow velocity of the air flowing through the divided air circulation passage on the accommodation space side of the air circulation passages allows heat inside the accommodation space to be efficiently radiated to the outside.
