| 20110043676 | CMOS IMAGE SENSOR AND IMAGE SIGNAL DETECTING METHOD - A CMOS image sensor includes a photodiode, a switch configured to transfer a signal sensed by the photodiode to a sensing node, and a comparator electrically and directly connected to the sensing node and configured to compare the sensed signal of the sensing node and a ramp signal. Reset offset of the comparator is maintained at a constant offset voltage level during an initialization mode. | 02-24-2011 |
| 20090262689 | METHOD AND APPARATUS FOR ALLOCATING RESOURCES TO A NODE IN AD-HOC NETWORK - A method of allocating resources to a node in an ad-hoc network includes storing a basic frame structure including a predetermined number of time slots, in which time slots to be used by the node in the ad-hoc network are arranged at predetermined positions, determining a start time slot among the predetermined number of time slots included in the basic frame structure based on a path sequence number that is a number related to a position of the node on a routing path, and determining a frame structure including the predetermined number of time slots from the start time slot in the basic frame structure that circulates as a communications frame structure for communications of the node. | 10-22-2009 |
| 20090207274 | Apparatus and method for adjusting white balance in a digital imaging device - A method and apparatus for adjusting a white balance in a digital imaging device. The method including the steps of: analyzing a histogram of an image to which a white balance algorithm is to be applied; classifying the image, to which the white balance algorithm is to be applied, according to color distribution determination criteria; and the white balance algorithm is applied to the image in a customized manner based on results of the classification based on color distributions. The apparatus includes an image sensor unit for photographing a subject and for creating an original image; and an image processing unit for finding an achromatic color region through estimation of a color temperature of the original image, for extracting a white point of the achromatic color region, and for adjusting a white balance of the original image. | 08-20-2009 |
| 20090141666 | WIRELESS SENSOR NETWORK USING DYNAMIC MESSAGE ROUTING ALGORITHM AND METHOD OF CONTROLLING THE WIRELESS SENSOR NETWORK - Provided is a wireless sensor network using a dynamic message routing algorithm and a method of controlling the wireless sensor network. Therefore, a network system can be provided, in which each sensor node calculates a relay probability, periodically updates the relay probability, and dynamically determines a node for relaying a message on the basis of the relay probability, so that throughput per node is improved and a media access control (MAC) layer is not needed. | 06-04-2009 |
| 20080283581 | Apparatus and method for connecting copper tubes - An apparatus and method for connecting copper tubes are developed to facilitate welding operation in the refrigerating device. The new apparatus will reduce the poor welding rate so that it will effectively prevent clogging of the copper tubes and leaking the refrigerant. It also has merit to easily determine a suitable heating time while the copper tubes are welding. Thus, the rate of poor welding is reduced, as well as a method for connecting copper tubes by using the tube connecting apparatus. | 11-20-2008 |
| 20080247391 | Method and apparatus for transmitting and receiving data in a communication system - A method for receiving multicast service data by a terminal in a communication system. The method includes receiving a pilot from a base station, measuring channel state information using the received pilot, and transmitting the channel state information to the base station; receiving a frame from the base station, and determining whether there is an error in the received frame; when no error has occurred in the received frame, determining whether the number of frames consecutively received without error is greater than or equal to a predetermined number; and when the number of frames consecutively received without error is greater than or equal to the predetermined number, transitioning to a non-feedback state where the terminal transmits no channel state information to the base station. The frame includes multicast service data. | 10-09-2008 |
