Publication number: 20240112571Abstract: A congestion prediction device, a congestion prediction method, and a storage medium are provided. A mapping outputs an output variable when input variables are input to the mapping. The output variable indicates a degree of congestion in a predetermined specific area. The mapping is learned in advance by machine learning. The input variables include congestion variables. Each of the congestion variables indicates a degree of congestion in the specific area at regular time intervals within a specific period. The output variable indicates a degree of congestion after a lapse of the regular time interval from an end time of the specific period.Type: ApplicationFiled: September 26, 2023Publication date: April 4, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ayumu SHIOMI, Atsushi MIYAGAWA, Hiroki TAKEUCHI, Toshiyuki KAWAI, Ryosuke FUKAYA, Hiroyuki TOKITA, Yusuke IKENOUE, Tsukasa KATO, Katsuhisa YOSHIKAWA, Yuta ICHIJYO, Takayuki AKAISHI, Shintaro KAWAI

Patent number: 8529534Abstract: An excrement treating apparatus 100 includes an excretion receiver 1 and an apparatus body 2. The excretion receiver 1 includes a receiver body 10 which receives excretions and an excretion sensor 20 which detects the excretions. The apparatus body 2 includes a urine tank 51 which stores urine, a vacuum pump 52 which sucks urine received by the receiver body 10 into the urine tank 51, and a control unit 53. The excretion sensor 20 includes a pair of urine sensor electrodes 21 and 22 which detect urine received by the receiver body 10. The control unit 52 controls so as to reverse the polarity of the urine sensor electrodes 21 and 22 at prescribed time intervals. In the excrement treating apparatus, the excretion sensor's sensitivity is stabilized and urination is accurately detected and treated.Type: GrantFiled: January 6, 2009Date of Patent: September 10, 2013Assignees: Hitachi, Ltd., Uni-Charm CorporationInventors: Tetsuya Tanaka, Yoshikazu Ishitsuka, Ryosuke Miyagawa, Ichiro Wada, Miou Suzuki

Publication number: 20110265889Abstract: An automatic urine collecting device (1) is provided with: a main tank (20) for collecting and containing urine received by a urine receiver; a body case for supporting the main tank (20); a suction pump (53) for sucking the urine, which is received by the urine receiver, into the main tank (20) through a urine flow path by sucking air within the main tank through an airflow path; a urine sensor for detecting urine; and a control device for outputting a control command on the basis of the result of the detection by the urine sensor. The urine sensor is provided with a main-tank infrared sensor (S31) capable of detecting bubbles present in the upper part of the urine contained in the main tank (20). The configuration enhances the reliability of the suction pump.Type: ApplicationFiled: December 4, 2009Publication date: November 3, 2011Applicant: Hitachi, Ltd.Inventors: Tetsuya Tanaka, Ryosuke Miyagawa, Yoshikazu Ishitsuka, Shigeharu Sayama
