Abstract: A slide module having a first slide member, a second slide member moveable with respect to the first slide member, and a biasing unit connecting the first slide member to the second slide member, is provided. The biasing unit includes a first linkage having a plurality of links, the first linkage having one end rotatably connected to the first slide member and the other end rotatably connected to the second slide member, a second linkage having a plurality of links, the second linkage having one end of the second linkage rotatably connected to the first slide member and the other end rotatably connected to the second slide member, and a biasing mechanism connected between the first linkage and the second linkage.

Abstract: The present invention discloses an apparatus and method for controlling a linear compressor which can actively handle load and efficiently perform an operation, by synchronizing an operation frequency with a natural frequency of a movable member varied by the load.

Abstract: Compressor including a supplementary torque providing part for reducing a speed of a piston (340) in compression of refrigerant, and increasing the speed of the piston (340) in drawing of the refrigerant, thereby reducing a compression rate of the refrigerant in compression relatively, and increasing a re-expansion rate, to maximize a suction efficiency.

Abstract: Disclosed is a system for controlling a compressor of a cooling system. The system includes: the compressor having a driving shaft that is rotatable clockwise and counterclockwise and operated by a power of a motor outputting different torque characteristics depending on the rotational directions of the driving shaft; a selector for selecting an output torque characteristic of the motor; a switching part for turning on or off the motor; and a control unit for controlling the selector to drive the compressor in a torque characteristic suitable for an object to be cooled. In an aspect of the invention, there is provided a method for controlling an operation of a compressor in a cooling system.
