    摘要: The purpose of the present invention is to measure the blood pressure of a living body in a noncontact and non-invasive manner. An experimental device 1 irradiates a subject 7 with microwaves from a transmission antenna 23 and a reception antenna 25 receives the reflected waves. Since the phase of the reflected wave varies with micro-movements of the body surface caused by the heartbeat, a pulse wave can be detected from the difference in phase between the emitted wave and the reflected wave. Additionally, the experimental device 1 continuously detects the blood pressure of the subject 7 from a blood pressure sensor 5 mounted on the subject 7 while continuously detecting the pulse wave. A frequency spectrum of the pulse wave of the subject 7 is generated by Fourier transformation of the pulse wave. A comparison of the spectrum and the blood pressure of the subject 7 detected by the blood pressure sensor 5 reveals a statistically significant positive correlation of the systolic blood pressure with an eighth harmonic wave from among frequency components of the pulse wave. On the basis of the experimental result, a device can be realized which detects a pulse wave of a subject in a noncontact and non-invasive manner using a microwave, and which measures the systolic blood pressure using the correlation therebetween.

    摘要: There is provided a charged particle emission device that can cause a charged object to quickly approach a target charged state. There is provided a charged particle emission device comprising a pre-emission state detection unit configured to detect a pre-emission charged state which is a charged state of a charged object before the charged particles are emitted, a learned model configured to receive a charged state of a charged object and a control parameter related to a control amount used for control of the charged particles to be emitted to the charged object to generate an estimated charged state which is a charged state of the charged object after the charged particles are controlled under the control parameter and emitted, an estimated charged state generation unit configured to input the pre-emission charged state and a plurality of control parameters to the learned model to generate a plurality of estimated charged states corresponding to the pre-emission charged state and the plurality of control parameters, a selection unit configured to select an estimated charged state closest to a target charged state from the plurality of estimated charged states, and an emission unit configured to control the charged particles based on the control parameters corresponding to the selected estimated charged state to emit the charged particles to the charged object.
