Patent number: 12236021Abstract: A pen-shaped position indicator is configured to capacitively couple with a sensor surface of a position detection apparatus. The indicator includes a pen-shaped body; a coil; a driving power production circuit configured to produce a DC voltage from an induced signal in the coil by a wireless interaction with a charging device; a signal production circuit connected to the driving power production circuit and configured to generate a signal based on the DC voltage to form a capacitive relationship between the pen-shaped body and the position detection apparatus; a first electrode; and a second electrode. The first and second electrodes are configured to form first and second capacitive relationships with the sensor surface, respectively, to generate detection signals in the sensor surface from which a first detection signal and a second detection signal distinguishable from each other are extracted and used to obtain angle information of the pen-shaped position indicator.Type: GrantFiled: November 14, 2023Date of Patent: February 25, 2025Assignee: Wacom Co., Ltd.Inventors: Yasuo Oda, Sadao Yamamoto, Yoshihisa Sugiyama
