Abstract:
A linear compressor which can perform the natural cooling capacity modulation, even if a capacitor connected to a motor is removed. The linear compressor includes a fixed member having a compression space therein, a movable member linearly reciprocated in the fixed member to compress a refrigerant sucked into the compression space, and one or more springs provided to elastically support the movable member in the motion direction of the movable member. The compressor also includes a motor connected to the movable member to linearly reciprocate the movable member in the axial direction, and a motor control unit performing the cooling capacity modulation by the reciprocation of the movable member according to a load, by controlling an AC voltage applied to the motor so that a stroke of the movable member can be proportional to the magnitude of the AC voltage applied to the motor.

Abstract:
Provided is a method of manufacturing an LED package, the method including preparing a mold die which includes an upper surface and a lower surface having an outer circumferential surface and a concave surface surrounded by the outer circumferential surface, the mold die having an outlet extending from the upper surface to the lower surface; preparing a base having a light emitting section formed therein; forming an inlet formed in a predetermined region of the base excluding the region where the light emitting section is formed; positioning the mold die on the light emitting section; forming a mold member by injecting a molding compound into the inlet of the base; and removing the mold die.
Abstract:
Disclosed herein is vibration motor. The vibration motor includes a bearing rotatably fitted over a support shaft which is installed to be perpendicular to a base. A hub is coupled to the bearing, with an eccentric member provided on the edge of the hub. A coil is mounted to the hub to form an electric field. A magnet having 2n poles is mounted on the base, and rotates the hub using electromagnetic force between the magnet and the coil. A detent magnet is mounted to the hub and stops the coil in the middle between the poles of the magnet.
Abstract:
A system and method for diagnosing a home appliance are disclosed. The home appliance outputs product information as a predetermined sound signal, and transmits the sound signal to a service center of a remote site over a communication network, such that a service technician of the service center can easily check a current status of the home appliance. When a diagnostic server of the service center analyzes the sound signal of the home appliance, it selects a plurality of preamble candidates and can effectively and correctly detect data using weights, so that it can quickly diagnose a faulty operation of the home appliance. An erroneous data analysis and its associated erroneous diagnosis are prevented, so that the diagnostic system provides a service for more correctly diagnosing a faulty operation of the home appliance and also increases user satisfaction and reliability of the home appliance.
Abstract:
An apparatus for providing duplicated shelf managers in an ATCA system is provided. The apparatus for providing duplicated shelf managers includes a hub/switch in a control backplane to allow a manager to access the duplicated shelf managers all the time from an external network while maintaining the switch configuration defined of the ATCA specification. The hub/switch connects Ethernet ports of the duplicated two shelf managers and Ethernet ports of the two switches at the same time, and connects the two shelf managers and the two switches to the Internet.
Abstract:
A home appliance and a home appliance system are provided. The home appliance may convert product information into an acoustic signal and externally output the same as a sound. The home appliance system may receive the sound, convert the same into the acoustic signal, and then inversely convert the acoustic signal into the product information and read the same. Accordingly, the home appliance may externally output the acoustic signal as the sound so that the user may be easily notified of transmission. Also, the home appliance system may easily transmit the sound to a management device to read the product information because the sound may be transmitted via a communications network.
