Provided is a lens shading correction device and method in an image sensor. The device comprises a brightness weight storage unit, an input image divider, and an input image brightness correction unit. The brightness weight storage unit stores a brightness weight for allowing one of representative brightness values to be a representative brightness value of a reference image block having a maximal representative brightness value. The input image divider blocks and divides an input image into input image blocks. The input image brightness correction unit corrects a brightness of the input image by multiplying brightness of input pixels by brightness weights.

Provided are a structure of an automobile electronic key for security and a method for performing the function thereof. It is determined whether at least one of a driver seat door closing signal and a brake pedal signal is on. A key fob of an automobile is requested to send the ID thereof, and the ID is received from the key fob when at least one of the driver seat door closing signal and the brake pedal signal is on. The key fob is authenticated using the received ID. An actuator is driven to move a locking member such that a car key is switched to a rotatable state when the key fob passes authentication. The actuator is driven to move the locking member such that the car key is switched to an unrotatable state when the key fob does not pass authentication.

The force or pressure sensor array of the present invention effectively has both flexibility and elasticity. Since the substrate itself is a kind of a polymer material, the substrate can be bent or expanded. Although silicon, which is a material of the semiconductor strain gauge, is easily broken and solid, mechanical flexibility can be secured if it is fabricated extremely thin. To this end, particularly, disclosed is a flexible force or pressure sensor array using semiconductor strain gauges 110, the sensor array comprising: a substrate 10 including: the semiconductor strain gauges 110 in which a plurality of elements formed in a certain array pattern is deformed by force or pressure, a pair of polymer film layers 120 and 130 having film surfaces contacted facing each other and containing the semiconductor strain gauge 110 between the film surfaces contacted with each other, and a pair of signal line layers formed on top and bottom surfaces of an insulating layer using either of the pair of polymer film layers 120 and 130 as the insulating layer and connected to the elements 111 of the array pattern to form electrodes, for fetching deformation signals outputted due to deformation of the elements 111 to outside; and a pair of elastomer layers 20 and 30 formed on both sides of the substrate 10 to contain the substrate 10 inside.

Disclosed herein is a makeup puff apparatus. A puff is coupled in such a way so as to be freely movable, and is very efficiently designed to have functionality including flexibility, elasticity and a restoring force, thus ensuring durability resulting from firm coupling and enabling reliable operation, and thereby considerably increasing the ease and convenience of use. Particularly, the apparatus enables flexible motion and adjustment of the puff in conformity with a variation in angle on a touch portion when the apparatus is in use, thus continuously maintaining a soft touch sensation of the puff, and allows the apparatus to be immediately restored to its original state, thus preventing the angle of the puff from deviating from a predetermined angle.

Provided is a data reception error reduction system and method in acoustic communication in audible frequency range, and an apparatus applied thereto. The data reception error reduction system in the acoustic communication in audible frequency range may be configured to reduce a data reception error in a receiver by taking into consideration that a sound signal is noisy and is significantly affected by a change in the ambient environment when the acoustic communication is performed in the audio frequency band through modification of an audio signal or adding of a predetermined signal to an audio signal. Accordingly, the data reception error may be reduced in the receiver even in an environment where a sound signal is noisy and is significantly affected by a change in the ambient environment, and reliability of data transmission may increase.
