Abstract:
The present invention relates to a steam head of a cleaner. The present invention includes a steam head including: a body defining an exterior, and a steam generating device provided on the body to generate steam through heating water supplied through a heater, the heater including a radiator of a ceramic material, and a plurality of insulation layers for insulating the radiator, wherein the plurality of insulation layers is formed of one of or a combination of one or more of magnesium oxide (MgO), a slurry-phase insulator, and an insulation film. Thus, through the present invention, a heater's heat radiating performance is improved to facilitate generation of steam.
Abstract:
An image processing apparatus includes a first pixel, a digitization unit, and a correction unit. The first pixel includes a first photoelectric conversion layer for outputting a first electrical signal in response to received incident light, including light of a first color, light of a second color, and light of a third color; and a second photoelectric conversion layer disposed under the first photoelectric conversion layer and for outputting a second electrical signal in response to light transmitted through the first photoelectric conversion layer. The digitization unit generates first original data by digitizing the first electrical signal and generates second original data by digitizing the second electrical signal. The correction unit generates first corrected data corresponding to the light of the first color and second corrected data corresponding to the light of the second color, by respectively correcting the first original data and the second original data.
Abstract:
A pixel array for an image sensor is provided. The pixel array includes a dark pixel which is configured to detect a local dark current in an active pixel block. The dark pixel is distinguished from an optical black pixel block which is arranged around the active pixel block and is configured to detect a global dark current. The pixel array is configured to compensate for dark shading, which is not compensated through global dark current compensation, using the local dark current output from the dark pixel which is arranged within the active pixel block.
Abstract:
The present invention relates to a device for accelerating the combustion of liquid fuel for improving the combustion efficiency of liquid fuel used in an internal combustion engine and a system for accelerating the combustion of liquid fuel using the device. The device is characterized in that magnets are provided in a metal pipe, and pure tourmaline ceramics and mixed tourmaline ceramics are used as a catalyst, so that fuel molecules are atomized by the magnetic field, generated by the magnets, and by far infrared rays, radioactive rays, and the like generated from the catalyst, thereby accelerating the combustion of fuel. The internal combustion engine using the device and system of the present invention can realize fuel savings and can reduce the discharge of environmental pollutants.
Abstract:
A method of determining acceptability of an image of a fingerprint to be analyzed, includes dividing the image into a plurality of blocks, determining a focus for each block, determining a validity of a block, the block being valid if the focus is sufficient, otherwise the block being invalid, totaling a number of valid blocks in the image, and determining a validity of the image, the image being valid if a number of valid blocks is sufficient.
Abstract:
A method of processing image signals comprises determining whether each of multiple units of input pixel data received from an image sensor is bad pixel data generated by a bad pixel of the image sensor or normal pixel data generated by a normal pixel of the image sensor, and performing interpolation to generate image data corresponding to the bad pixel using only normal pixel data and omitting bad pixel data.
