Patent number: 11611278Abstract: Power line patterns are, together with a ground pattern, provided separately from control line patterns. The power line pattern is formed at first and second major surfaces of a circuit board. When the circuit board is viewed in plan view, the power line pattern and the power line pattern form a line structure in which the power line pattern and the power line pattern are in parallel with and opposite to each other and the power line pattern is positioned under the power line pattern. The circuit board includes a dielectric between the power line pattern and the power line pattern. These together form an equivalent capacitor and the magnetic flux induced by the current flowing through the power line pattern and the magnetic flux induced by the current flowing through the power line pattern cancel each other out.Type: GrantFiled: December 21, 2020Date of Patent: March 21, 2023Assignee: Murata Manufacturing Co., Ltd.Inventors: Osamu Miki, Tatsuya Hosotani

Publication number: 20210137078Abstract: Provided are a livestock sensor device, a livestock astasia inference method, a livestock astasia inference program, and a livestock management system that are capable of preventing damage to stockbreeders. According to an embodiment of the present technology, there is provided a livestock sensor device including a postural-state determination unit, a state inference unit, a transmission unit, and a casing. The postural-state determination unit determines in which of a prostrate state and a non-prostrate state a livestock animal has been on a basis of output values from an acceleration sensor. The state inference unit infers whether or not the livestock animal has developed astasia on a basis of a duration of the prostrate state. The transmission unit transmits, to a server, an astasia-notification data item indicating that an inference that the livestock animal has developed the astasia is made when the inference that the livestock animal has developed the astasia is made.Type: ApplicationFiled: July 10, 2018Publication date: May 13, 2021Inventors: HIDETATSU YAMAMOTO, SEIJI OHISHI, HIDETOSHI ISAWA, KAZUHIKO TSUJI, NAOKI TAMAI, HIDEAKI KAMEI, YOSHINORI USAMI, TAKESHI NEGORO, KOICHI YAMAGUCHI, KAZUYA TERASAKI, OSAMU MIKI, KENJI SASAKI, TOMOYA IMAMURA, MAMI MAMIYA
