Patent number: 11794807Abstract: The steering control apparatus determines whether or not a deviation degree of a current traveling route of a vehicle with respect to a target traveling route is equal to or more than a predetermined threshold, when steering control is switched from manual steering control to automatic steering control.

When a pulse wave is transmitted to the vibration ring 40 from the skin, the board 20 also vibrates and this vibration is transmitted to the piezoelectric element 30. Then, the piezoelectric element 30 is displaced and the pulse wave vibration is converted to an electrical signal. The resulting electrical signal is amplified by an amplifier on the board 20 and input to the vibration analysis device 100, where prescribed calculations are run to perform waveform analysis. The vascular state, etc., can be known from pulse waveforms.Type: GrantFiled: April 9, 2016Date of Patent: November 24, 2020Assignee: TAIYO YUDEN CO., LTD.Inventors: Takashi Ishiguro, Keiichi Kobayashi, Yutaka Aoki
