Abstract: An electronic device for estimating body temperature may include: a sensor including a heat source, a pair of first temperature sensors horizontally spaced apart from each other at two opposing sides of the heat source, and a pair of second temperature sensors vertically spaced apart from the pair of first temperature sensors in a thickness direction of the electronic device; and at least one processor configured to estimate a blood temperature difference based on temperatures measured by the pair of first temperature sensors and the pair of second temperature sensors, and estimate blood flow information based on the estimated blood temperature difference.

Abstract: A fluid flow control device for a faucet piece with which anyone is able to easily control flow rate, flow velocity, hydraulic pressure, water stream size, and the like and includes a water dispersion means, a cylindrical type mounting member, a rotation guide means, and a control position stopper means.

Abstract: A PET container cap, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, is proposed. The cap includes a cap body which is provided on and coupled to the injection part so as to provide tight blocking for preservation of contents; and an end ring which is integrally formed at the lower side of the cap body, is restricted by an annular protrusion formed at the lower side of the outer circumference of the injection part, exhibits a sealing function enabling grasping of openness of the cap body, and causes transformation in a separation process of the cap body by a user, so that the end ring is simultaneously separated together with the cap body from the injection part.
