Abstract: Balanced and round mass of an object, herein called as a flywheel, has moment of inertia at the center of mass that is Icom=½ MR{circumflex over (?)}2, where M=mass R=radius. At the rim of mass the moment of inertia is, Irim=Icom+MR{circumflex over (?)}2= 3/2MR{circumflex over (?)}2. This shows three times more in moment of inertia at the end of R. Transferring this increased moment of inertia to the next flywheels for further increase and applying wheel-and-axle moment arm is the core of this invention.

Abstract: A locking module is coupled to first and second bodies that are movably connected to each other to be selectively spaced apart from each other and disposed close to each other, and the locking module includes: a first locking unit configured to be attached to the first body; and a second locking unit configured to be attached to the second body and to be detachably coupled to the first locking unit on the same line.

Abstract: A lens actuating unit is provided. The lens actuating unit includes: a bobbin configured to accommodate a lens module at an inner side of the bobbin; a first coil unit disposed at the bobbin; a housing disposed at an outer side of the bobbin; and a magnet unit configured to move the first coil unit through electromagnetic interaction with the first coil unit, wherein the housing includes a hole formed by being recessed from an inner side to an outer side to accommodate the magnet unit.

Abstract: A cradle device for a computer according to an embodiment includes: a cradle part configured such that the inlet part is seated thereon and holes through which air flows are formed therein; a filter part configured to filter out foreign substances generated according to the flow of air; and a filter housing part configured such that the filter part is coupled to a top surface thereof, and fixedly coupled below the holes of the cradle part. The filter part includes a first filter part made of a mesh material, and filters out foreign substances through the first filter part before air is introduced into the inlet part.

Abstract: A method for simulation of an autonomous vehicle includes preparing a setting of a parameter and an initial value configured to determine a driving condition of the autonomous vehicle and a driving condition of an event to be performed by a surrounding vehicle to implement a simulation environment of the autonomous vehicle. The method further includes performing a normal driving in which the surrounding vehicle travels at a speed and a position that match a predetermined condition set in the parameter to perform the event given, and performing an event driving in which the surrounding vehicle performs the event given based on a setting value of the parameter.
