Publication number: 20250104838Abstract: In an activity support device, a plan acquisition means acquires a target physical activity amount of a user in a predetermined period and a predictive physical activity amount representing an expected expenditure of a physical activity amount. An expended physical activity amount acquisition means acquires an expended physical activity amount of the user up to a current time in the predetermined period. A total expended physical activity amount acquisition means derives a total expended physical activity amount of the user in the predetermined period, based on the predictive physical activity amount and the expended physical amount. An activity determination means determines a physical activity to the user from among physical activity options by comparing the target physical amount and the total expended physical amount. Accordingly, it is possible for the activity support device to support a user in making a decision regarding the physical activity.Type: ApplicationFiled: September 26, 2024Publication date: March 27, 2025Applicant: NEC CorporationInventors: Tatsunori NAGASAWA, Masaru Yanai, Seishi Handa, Tomonori Ishida, Makoto Iwasaki, Noriaki Kobayashi, Takashi Kojima, Naoko Kurisaki, Hideki Muramatsu, Motoharu Ohtake, Nanami Sakurai, Yasuyuki Taguchi, Takayuki Takimoto, Noritsugu Yamanaka, Kosei Kobayashi

Publication number: 20230159766Abstract: A conductive polymer composition containing: a composite containing a ?-conjugated polymer (A) and a polymer (B) shown by the following general formula (2); H2O (D) for dispersing the composite; and a water-soluble organic solvent (C). This provides a composition which has favorable filterability and film formability, and which is capable of relieving acidity and forming a conductive film with high transparency. Moreover, since the H2O dispersion of the conductive polymer compound is mixed with an organic solvent, the surface tension and the contact angle are so low that leveling property on a substrate is imparted. The composition is usable in droplet-coating methods. Since an organic solvent having a higher boiling point than H2O is used as the organic solvent, the composition can avoid solid content precipitation around a nozzle and solid content precipitation due to drying between ejecting the liquid material from a nozzle tip and landing on a substrate.Type: ApplicationFiled: March 24, 2021Publication date: May 25, 2023Applicant: SHIN-ETSU CHEMICAL CO., LTD.Inventors: Takayuki NAGASAWA, Jun HATAKEYAMA
