Abstract: Proposed is a portable self-power-generating apparatus which has small size and is capable of charging a battery by realizing self-power generation with high efficiency in emergencies in which normal electricity supply is not available, such as a military operation, a refugee village, a disaster caused by earthquake or the like, an emergency situation on ships, or an outdoor activity, and which can be used in combination with various smart modules.

Abstract: The present invention relates to a hairband for guiding sweat, which can guide and discharge sweat running down from a user's head area to a user's forehead area so as to prevent the sweat from reaching eye areas during exercise or working. A hairband for guiding sweat, which is flexibly worn on a user's forehead area and guides sweat, the hairband may comprise: a band part including a first band member and a second band member, each of which includes a coupling member which may be coupled to and mounted on the user's forehead area; and a sweat guiding part disposed between the first band member and the second band member, wherein the band part and the sweat guiding part are integrally formed. Therefore, the hairband can simplify a manufacturing process and thus reduce a manufacturing cost.

Abstract: Disclosed are a portable private power generation apparatus, and a module equipped with same, the portable private power generation apparatus being small in size, and capable of efficiently generating private power to charge a battery, and able to be linked and used with a variety of smart modules when customary power cannot be supplied in times of emergencies such as during military operations, in refugee camps, during disasters due to earthquakes and the like, emergency situations on ships, and outdoor activities. The present invention comprises: a rotatable fly-wheel member; first and second rotating members for rotating the fly-wheel member; first and second wires for rotating the first and second rotating members, respectively, by means of a pulling action; first and second spring members for carrying out winding actions of the respective first and second wires; and a power generation member for generating power from the rotation of the fly-wheel member.
