A heating device capable of uniform sealing according to the disclosure comprises a heater for heating the sealing portion of the to-be-sealed object; a heat source supplier for supplying a heat source for heating to the heater; a heat transfer part accommodated in the heater, and transferring the heat source to the heater to heat the entire heater at a uniform temperature, and an additional heat transfer part disposed on the outer surface of the heat transfer part to conduct the heat source to the heater and in contact with the inner surface of the heater.
Abstract:
An apparatus and method for adaptively changing clock frequencies of a Central Processing Unit (CPU) and a bus in a digital system are provided. The system includes an Adaptive Frequency Scaling (AFS) controller and a clock controller. The AFS controller determines whether to change a clock frequency of the CPU according to operation information of the CPU, and determines whether to change a clock frequency of the bus according to operation information of the bus. The clock controller generates a clock frequency of the CPU and a clock frequency of the bus according to the determination of the AFS controller.
Abstract:
A digital camera capable of variably setting a frame rate may include an imaging device which outputs a plurality of temporally continuous image frames when photographing a moving image. The digital camera may also include a digital signal processor that determines a frame rate with which the image frames are filed, wherein the digital signal processor variably determines the frame rate according to a motion speed of a subject in the frames. The digital camera may further include a recording medium in which the filed image frames are stored. Accordingly, as the frame rate is varied according to the motion of a subject, the motion of the subject can be smoothly realized in a high motion speed section from a reproduction perspective, and substantially repeated image frames can be removed in a low speed motion section. Thus, the size of moving image files can be reduced, saving memory resources.
Abstract:
An apparatus and method for dynamically controlling a clock signal in a pipeline system are provided. In the apparatus and method, a clock generator outputs the clock signal at every period, a PDR is included with each stage for outputting information about a processing speed of each stage, and a CCU controls the delay of the clock signal using the processing time of each stage received from the PDR and providing the clock signal with the controlled delay to a register between stages. Accordingly, the clock signal is dynamically controlled to provide higher operating speeds.
Abstract:
Disclosed is a photographing apparatus using an infrared ray in a portable terminal, the apparatus includes: a camera module for photographing an image; a display unit for providing a preview for the image photographed by the camera module; and an infrared sensor unit for determining if light is obstructed by emitting and receiving an infrared ray through an infrared sensor upon photographing by the camera module, and outputting a photographing signal for the image.
Abstract:
A method for generating an interrupt signal in a memory controller and supporting a multi-processor is provided. Whether an access for a determined memory region occurs is determined. When the access for the determined memory region occurs, whether the access for the determined memory region has a right is determined. When the access for the determined memory region has the right, a core that will generate an interrupt signal is determined. The determined core is requested to generate the interrupt signal.
Abstract:
The cosmetic container for mixing and using heterogeneous stuff is disclosed, which makes it possible to discharge certain amounts of heterogeneous cosmetics from a pair of discharge ports and simply mixing the same by forming an elliptical mixing part which has an inwardly inclined surface at an upper side of a cosmetic container.
Abstract:
Disclosed are an apparatus and a method for estimating a channel in a base station when using an Optional Partial Usage of Sub-Channels (OPUSC) mode in an uplink channel of a communication system supporting Orthogonal Frequency Division Multiplexing/Orthogonal Frequency Division Multiple Access (OFDM/OFDMA). In order to estimate the channel in the OFDM/OFDMA communication system, according to the present invention, pilots and data are extracted from input signals, phase change caused by time delay is estimated using the extracted pilots and data, and a channel estimation value is obtained by reflecting the estimated phase change.
Abstract:
The present invention relates to an electronic commerce system of a group-driven purchase broker type and a shopping mail operating system, wherein buyers can jointly purchase merchandise at a price lower than a regular price through a purchase broker group who negotiates prices with sellers, and sellers can make more profits owing to the increase of sales amount since a buyer does not individually purchase merchandise, but a plurality of buyers collectively purchase merchandise through the purchase broker group even though the sellers sell merchandise at a reduced price lower than the regular price. The electronic commerce system of the present invention comprises a shopping mall operating company; a sales client; a group client connected to the shopping mall operating company; a purchase client; and a wired/wireless communication network for connecting the shopping mall operating company, the sales client, the group client and the purchase client with one another.
Abstract:
Apparatus and method are disclosed for selecting a transmit antenna diversity scheme according to a variation speed of a fading channel in a mobile communication system. A user equipment (UE) estimates a channel response of a pilot channel by receiving a pilot channel signal from a Node B; estimates a variation speed of a fading channel by using the estimated channel response and determining a transmit antenna diversity scheme suitable to the variation speed of the fading channel; and transmits feedback information including the determined transmit antenna diversity scheme to the Node B, so that the Node B can determine a transmit antenna diversity scheme for a channel signal to be transmitted to the UE based on the transmit antenna diversity scheme information included in the feedback information. In this way, the Node B adaptively applies a transmit antenna diversity according to a channel condition.
