Patent number: 10712192Abstract: An information processing apparatus includes a communication interface and a controller. The communication interface receives, from a sensor container, information indicating an orientation of the sensor container. The controller, based on the information indicating the orientation of the sensor container, calculates a calculated value indicating a remaining amount of contents of the sensor container. The controller determines an estimated value of the remaining amount on the basis of the calculated value. The communication interface transmits the estimated value indicating the remaining amount to an external device. When the calculated value indicating the remaining amount decreases by a first predetermined value or more within a predetermined time period, the controller does not perform the determination of the estimated value on the basis of the calculated value.Type: GrantFiled: October 23, 2017Date of Patent: July 14, 2020Assignee: KYOCERA CORPORATIONInventors: Yasuhiko Fukuoka, Takahisa Yamamoto, Djuniadi Arifin Sagala, Katsuro Nakamata, Takanori Ikuta, Shinji Isoyama, Jun Kitakado, Takahiro Saiwai, Atsuhisa Inakoshi, Nobuki Hiramatsu, Takuya Kuribayashi, Sunao Hashimoto
