Publication number: 20210049889Abstract: The present invention addresses the problem of enabling another person to easily acquire the current status of a person who has difficulty transmitting information indicating the current status of said person's body to the other person. A detection unit 12 detects a physical amount based on pressure from at least a portion of a person's leg. A management unit 11 transmits prescribed information from a transmission unit 112 when the physical amount detected by the detection unit 12 satisfies a prescribed standard. The transmission unit 112 can also transmit, as prescribed information, information that is used to specify a position at which a transmission device 1 is present. Through this, the abovementioned problem is solved.Type: ApplicationFiled: March 8, 2019Publication date: February 18, 2021Applicant: SYSTEM 21 Inc.Inventors: Yoshiko FUKUDA, Takafumi KUBO, Yoshitaka TANAHASHI, Masashi MIHARA, Masahide TOMITA
