    摘要： The present invention provides a backlight assembly and a display system having the same, characterized in that the backlight assembly comprises: a plurality of light emission units and a control unit. Each unit having M kinds of emission components, each of the M kinds of emission components emitting light of a spectrum which is different from each other, wherein M is a positive integer equal to or greater than two. The control unit receives a first signal and determines a second signal according to the color information of the first signal, and individually controls light emission of each emission component of the plurality of light emission units based on the second signal, wherein the light emissions from the plurality of light emission units generate a spatially-dependent spectrum distribution, and the light emission of each light emission unit forms a color gamut in a color space which is individually different from others.

    摘要： A method of converting an image signal from an original dynamic range to a target dynamic range includes dividing the original dynamic range and the target dynamic range in to a plurality of corresponding sub-ranges and mapping each original sub-range to its corresponding target sub-range. One of the dynamic ranges is divided into a plurality of sub-ranges having equal size and the other dynamic range is divided into the corresponding sub-ranges each having a size based on a characteristic of the corresponding equal size sub-ranges. The invention may be employed in display, capture and image processing apparatus.

    摘要： A method of reducing power consumption in a liquid crystal display illuminated by a backlight device includes dimming the backlight and adjusting the intensity of the image to compensate for the dimmed backlight. A dimming factor for the backlight is based on a clipping point determining from the pixel intensity distribution of the image signal. The intensity of the image is adjusted based on the dimming factor, wherein a first tone mapping function is used to adjust pixel intensities below an intensity threshold and a second tone mapping function is used to adjust pixel intensities above the intensity threshold.

    摘要： Methods and apparatus for expanding a rod from a collapsed position to a formed position are disclosed. One such apparatus includes a plurality of segments for forming the body of the collapsible rod including with each segment coupled to each immediately adjacent segment of the plurality of segments. The apparatus may include a coupler for coupling each segment of the plurality of segments to each immediately adjacent segment of the plurality of segments. The coupler may stretch from a base segment to the tip of the apparatus and may be biased to apply a force to hold the plurality of segments in a formed position and to urge the plurality of segments into a formed position from a collapsed position. In the formed position, the plurality of segments may be aligned end-to-end to form a rod and in the collapsed position, the plurality of segments may be folded against each other such that cylindrical walls of each of the plurality of segments are positioned adjacent each other.

    摘要： A convertible bullet-proof backpack and vest includes a body section divided into a front portion, a middle portion, and back portion. The middle portion has a head slot opening, and the front and back portions have respective sections of bullet-proof fabric integrated therein. A zipper runs around an outer perimeter of the front and back portions. In a backpack configuration, the front portion and the back portion fold toward each other and the zipper secures the outer perimeters of the front portion and the back portion together thereby forming a hollow backpack interior between them. In a bullet-proof vest configuration, the zipper is unzipped thereby allowing a user to insert their head through the head slot opening such that the front portion hangs in front of a torso of the user and the back portion hangs behind the torso of the user.

    摘要： The present invention strategically utilizes the sturdiness of thin wires enwrapped inside a thick layer of soft material such as silicone rubber which is smoother and softer than human tissue. Therefore, the device doesn't cause any damage or side effect and feels comfortable to user. The exposure of skin is 90% or higher, therefore solves the lack of sensation issue faced by prior art devices. The device is hard and yet flexible, the side walls or double bars are positioned toward ventral side of the device so that it is pleasing to the eye during use in addition to feeling good by the user.
