  • Patent number: 11937902
    Abstract: Blood pressure is estimated in a non-constraining manner continuously and in real time. A biological signal collected from a person's dorsal part is analyzed, vibration in the human body ascribable to a blood flow rate change in a period from the ventricular filling period to the isovolumetric systole is captured, and the state of fluctuation of an index indicating the state of the in vivo vibration is further captured. This fluctuation index correlates with a person's blood pressure. Therefore, it is possible to estimate whether the blood pressure is in a range indicating a normal-range blood pressure or in a range indicating a high blood pressure, only by having the person sit or lie supine on a surface provided with a biological signal measurement device to measure a biological signal in a non-constraining manner, so as to make the biological signal measurement device contiguous with the person's dorsal part.

  • Patent number: 11937931
    Abstract: The occurrence of a sudden change in physical condition is detected. In a physical condition determination device 100, a heart rate-relate index calculation unit 110 specifies an appearance time of a sign of a sudden change in heart rate, from a time-series waveform of an index corresponding to a variation in the heart rate (heart rate-related index) and a blood pressure-related index calculation unit 120 specifies an appearance time of a sign of a sudden change in blood pressure, from a time-series waveform of an index corresponding to a variation in the blood pressure (blood pressure-related index). A physical condition sudden change determination unit 130 determines that a sudden change in physical condition (physical condition sudden change) has occurred in a case where these appearance times are both within a predetermined time.

  • Patent number: 11939751
    Abstract: A faucet spout mounting system including a faucet spout tube, an inner adapter, and a bushing. The bushing is positioned radially intermediate the outer spout tube and the inner adapter. The inner adapter and the bushing engage to push flexible arms on the bushing against the outer spout tube, thus holding the bushing in place and compensating for tolerances in the spout mounting system.

  • Patent number: 11933309
    Abstract: A method for controlling a fan in a fan start-up stage including a first time period and a second time period comprises the following steps of: during the first time period, continuously providing a first driving signal to drive the fan; and during the second time period, continuously providing a second driving signal to drive the fan; wherein, the signal value of the first driving signal gradually decreases until being equal to the signal value of the second driving signal. Wherein the signal value of the first driving signal non-linearly decreases, the signal value of the second driving signal is an unchanged value. Wherein, the first time period and the second time period are adjusted for a different fan but the sum of the first time period and the second time period is always the same. A fan is also disclosed.
