  • Publication number: 20170273574
    Abstract: A wearable physiological measuring device has a torso-worn module and a limb-worn module configured to communicate in a wireless way with each other. The torso-worn module is configured to be coupled with a torso of a user to obtain an R-peak from an electrocardiac signal. The limb-worn module is configured to be coupled with at least one limb of four limbs of the user to obtain a pulse wave peak from a plethysmograph signal. There are no physical connections (neither wire nor cable) between the torso-worn module and the limb-worn module. The wearable physiological measuring device is configured to use the R-peak time and the pulse wave peak time to generate a pulse transit time data.

  • Patent number: 9735670
    Abstract: A power factor correction conversion device and control method thereof are adapted to send an AC signal to a power factor correction conversion device, convert the AC signal into a DC signal, and perform power factor correction of the DC signal, so as to change a power factor sent to a back-end load, wherein the control method includes a rectification step, a feedback step, a ripple calculating step, a ripple offsetting step, a logical computation step, a pulse width modulation step and a power factor correcting step. Hence, the second-order ripple component in a feedback signal is eliminated to thereby increase the response speed of the power factor correction conversion device and reduce the distortion rate of the current, thus increasing the power factor sent to the back-end load.
