Abstract: An infusion flow regulator includes: a main body having an inlet through which fluid is introduced and an outlet through which the fluid is discharged; and a rotary dial rotatably coupled to the main body, with a sealing member interposed therebetween, so as to regulate a flow rate of the fluid, in which the rotary dial includes a regulating flow path having a shape of a recessed groove in cross section with a first width and a first height, and the regulating flow path includes a first region in which the first width is constant and the first height is decreased, and a second region in which both the first width and the first height are decreased. By the aforementioned configuration, the infusion flow regulator for the fluid can accurately regulate the flow rate even in a region where the flow rate of the fluid is very small.

Abstract: As a component of an aerial vehicle, a power management system having an active power control device is provided. The system includes a solar cell converting solar energy into electric energy; a fuel cell provided in the aerial vehicle and converting fuel energy into electric energy by electrochemical reaction; a battery compensating for a lack of electric power supplied from the solar cell and the fuel cell to the aerial vehicle and storing surplus electric power; and an active power control device connecting with all the solar cell, the fuel cell and the battery and combining and distributing electric power generated in the solar cell, the fuel cell and the battery to loads. The system efficiently distributes the power from the respective power sources through the controllable output of the fuel cell in accordance with power required by the aerial vehicle and the solar cell's performance depending on weather.
