  • Publication number: 20160055057
    Abstract: An operating method of an error correction decoder includes receiving data, setting initial log-likelihood values of variable nodes, and decoding the received data by updating a log-likelihood value of a selected variable node by use of a minimum value and a minimum candidate value associated with the selected variable node. The minimum value indicates a minimum value of absolute values of log-likelihood values of first variable nodes sharing a check node with the selected variable node and including the selected variable node. The minimum candidate value indicates one, greater than the minimum value and smallest, from among absolute values of log-likelihood values of second variable nodes that are selected later than one, corresponding to the minimum value, from among the first variable nodes.

  • Publication number: 20150150429
    Abstract: A cleaning robot having improved traveling performance and a method of controlling the same. The cleaning robot detects a stuck state such as a ‘jammed state, ‘lifted state’, or ‘object-caught state’ by using a motion instruction or sensor information and quickly escapes from the stuck state caused in various traveling conditions by using a wheel structure capable of changing a total height of the cleaning robot. In addition, a degree of risk and type of the stuck state is predicted before the cleaning robot is in the stuck state so that the cleaning robot may deal with the stuck state in advance. The cleaning robot may escape from the stuck state via rapidly deceleration or quick stopping in accordance with the predicted degree of risk of the stuck state, and the cleaning robot may efficiently deal with the stuck state by using information to select an escaping method suitable for the type of the stuck state.

  • Patent number: 8761939
    Abstract: A robot system and a control method thereof in which, when a robot is located in a docking region, the robot calculates a distance by emitting infrared rays and detecting ultrasonic waves oscillated from a charging station, measures a distance from the charging station and performs docking with charging station. The distance between the robot and the charging station is precisely measured, thereby performing smooth and correct docking of the robot with the charging station. Further, the robot emits infrared rays only while performing docking with the charging station and thus reduces power consumption required for infrared ray emission, and wakes up a circuit in the charging station based on the infrared rays emitted from the robot and thus reduces power consumption of the charging station.
