  • Information processing device and information processing method that enable simple calibration
    Patent number: 11959775
    Abstract: Provided is an information processing device and an information processing method that enable simple and appropriate calibration. When a pen-type device incorporating an inertial measurement unit such as an IMU is moved and a drawn image corresponding to a track is displayed, calibration is implemented on the basis of a measurement value of the inertial measurement device in one stationary attitude and a latitude and an absolute azimuth of the inertial measurement device at that time when the pen-type device is inserted into a pen stand to be fixed in a predetermined direction.

  • Electric cells
    Patent number: 4939050
    Abstract: An electric cell comprising a positive electrode, a negative electrode, and an electrolyte maintains excellent performance when the positive electrode is an electro-conductive polymer composite including a mesh stainless steel having a wire diameter of about 35-120 .mu.m and an electro-conductive polymer, typically polyaniline, integrally deposited onto the mesh by electrolytic polymerization. A container having the elements received therein is provided with a vent mechanism.
