Abstract: A linear compressor includes a shell, a motor in the shell, a mover coupled to the motor and configured to perform a reciprocating motion in an axial direction, a cylinder disposed in the shell, a piston coupled to the mover and configured to reciprocate in the cylinder, a spring that supports the piston in the axial direction, and a spring cap inserted into an end portion of the spring. The spring cap defines a space portion that is defined inside the spring cap and has a volume separate from the inner space of the shell, and a passage portion that extends through an axial side surface of the spring cap and is configured to provide communication between the space portion and the inner space of the shell.

Abstract: Disclosed are a vehicle control method and an intelligent computing device for controlling a vehicle. The processor can detect a gaze response speed of the driver by projecting a virtual object to an HUD when determining that the driver is in a drowsy state. The processor outputs a secondary warning and controls the vehicle to be driven in accordance with the secondary warning when the gaze response speed of the driver is less than a predetermined reference value. Accordingly, it is possible to reduce accidents that occur due to carelessness of drivers. Disclosed are a vehicle control method and an intelligent computing device for controlling a vehicle.

Abstract: A reciprocating compressor is provided that may include a shell including a vibration absorbing member formed to be wound around an outer circumferential surface or an inner circumferential surface or stacked thereon, so that compressor vibration may be attenuated by frictional contact between the shell and the vibration absorbing member or between layers of the vibration absorbing member. Also a noise insulating layer may be formed between the shell and the vibration absorbing member or between the layers of the vibration absorbing member, so that a magnitude of noise may be reduced as vibration noise passes through the noise insulating layer, whereby vibration noise of the compressor, such as noise of a high frequency band, may be further attenuated by fine vibration.
