| 20090009603 | Device and method for detection and prevention of motor vehicle accidents - A device and method for vehicle collision avoidance and mitigation employing a video camera providing a frontal view of a roadway to a video display. A plurality of generally trapezoidal windows formed in front of and rearward of an iconic vehicle are employed to ascertain objects in front of and rearward of the vehicle. Using software, a closing rate of any object is continually calculated, and warnings or evasive actions are taken if a collision is calculated. The device can differentiate between shadows and objects through a filtering method requiring pixel changes in two or more windows concurrently for an object to be determined. | 01-08-2009 |

| 20090213244 | APPARATUS AND METHOD FOR CORRECTING BACKLIGHT OF CAMERA - An apparatus and method for correcting the backlight of a camera are disclosed. When the camera for photographing a moving image by a photographing device, such as a general-purpose CCD or a general-purpose CMOS, enters into a backlight shooting state for simultaneously photographing an object with a very high luminance level and an object with a very low luminance level, as the shutter speed of the photographing device is varied to a long shutter speed and a short shutter speed, an image shot with the long shutter speed and an image shot with the short shutter speed are synthesized and outputted, thereby enabling a proper luminance level object photographing operation for each of the objects. Accordingly, it is possible to efficiently prevent the phenomenon that the object with the low luminance level looks dark due to the object with the high luminance level. | 08-27-2009 |
| 20090303356 | APPARATUS AND METHOD FOR REMOVING BLOOMING OF CAMERA IMAGE - An apparatus and a method for removing blooming of a camera image are provided. When a lane marking is not normally detected from an image obtained by photographing a front view or a rear view of a car, it is determined whether the blooming is generated in the image. When it is determined that the blooming is generated, a mask for removing the blooming is generated and superposed on the image. Accordingly, a situation that the lane marking is not normally detected due to the blooming caused by a head light of a car can be reduced or prevented in advance. | 12-10-2009 |
| 20090303372 | APPARATUS AND METHOD FOR CONTROLLING IMAGE SENSOR OUTPUT - An apparatus and method for controlling an image sensor output are discussed. When a certain number of valid pixels of an image sensor, such as a CCD, is selected, a corresponding timing parameter is calculated. Signal values output from charge wells respectively corresponding to unit cells of the image sensor are separated or merged and then output by using the calculated timing parameter. Therefore, an image of a user-defined number of valid pixels can be varied and output in various ways, and all electric charges that are photoelectrically converted by the maximum number of valid pixels of the image sensor can be efficiently used. | 12-10-2009 |

| 20090095305 | Apparatus for preventing sleeping respiratory obstruction and method using the same - An apparatus for preventing a sleeping respiratory obstruction of a sleeper includes first and second air chambers provided to correspond to both sides of a back of a human body, respectively, so as to be shrunk and expanded, an air supply unit for supplying air to the first and second air chambers so as to expand the first and second air chambers, and an operation selection unit for selecting whether to operate one of the first and second air chambers or to alternately operate the first and second air chambers. A controller controls the air supply unit to control air supply and discharge to and from the first or second air chamber so as to operate one of the first and second air chambers or to alternately operate the first and second air chambers according to the selection result in the operation selection unit. | 04-16-2009 |
| 20100051037 | CLOTHES AND METHOD FOR PREVENTING SLEEPING RESPIRATORY OBSTRUCTION AND/OR DECUBITUS - Clothes have a capability of preventing sleeping respiratory obstruction and/or decubitus, which is worn by a user. The clothes include a plurality of air chambers provided at the rear of the clothes, the air chambers being capable of being shrunk and expanded. An air supply unit supplies air to each of the air chambers, and a pressure detecting unit measures the pressure of each of the air chambers to produce a measured pressure as an electrical signal. A controller receives the measured pressure signal from the pressure detecting unit to supply the air to the air chambers by using the air supply unit when a snoring or a sleep apnea of the user is detected or a predetermined time elapses in the same posture in order to change a posture of the user. | 03-04-2010 |
