Abstract: A horn antenna for a millimeter wave comprises: a horn radiator including a radiation part having an opening formed therein to radiate a feed signal, and a multi-layer PCB coupling part coupled to lower and side portions of the radiation part to provide a feed signal; and a multi-layer PCB coupled to a lower portion of the multi-layer PCB coupling part to provide a feed signal, wherein a slot and a groove connected to the slot and extending in a direction parallel to the multi-layer PCB are formed in the multi-layer PCB coupling part, wherein a feed line vertically overlapping the slot and the groove is formed on a first layer substrate, which is the uppermost layer of the multi-layer PCB, wherein the opening extends in a direction parallel to the multi-layer PCB, and wherein a ‘¬’-shaped waveguide extending from the slot is formed in the horn radiator.

Abstract: A display device includes: a display panel; a heat dissipation sheet on a surface of the display panel; a circuit board electrically connected to the display panel, the circuit board being on a surface of the heat dissipation sheet; and a vapor chamber attached to the surface of the heat dissipation sheet to emit heat transferred through the heat dissipation sheet. The circuit board overlaps with a first area of the heat dissipation sheet. A first part of the vapor chamber is attached to a second area of the heat dissipation sheet, and a second part of the vapor chamber is spaced apart from the heat dissipation sheet.

Abstract: The present invention relates to an adhesive comprising an anti-insect ingredient comprising a plant extract, wherein the plant extract comprises an extract of Cinnamomum cassia, an extract of Syzygium aromaticum and an extract of Artemisia capillaris and an adhesive ingredient comprising a binder. The adhesive is environment friendly and does not have any toxic ingredient on a human body and exhibit excellent and synergic anti-insect efficiency by using three plant extracts. Therefore, it is possible to control pests that may have an adverse effect on foods by applying the adhesive to a food package box.

Abstract: An image capture device and a method of calibrating automatic white balance thereof are provided. The method includes generating first and second frame data using first and second image sensors, respectively, in response to incident light; generating first and second color temperature estimation information based on the first frame data and the second frame data, respectively; determining whether an amount of the first color temperature estimation information is sufficient to estimate a color temperature of a light source; estimating the color temperature of the light source based on the first color temperature estimation information when the amount of the first color temperature estimation information is sufficient; and when the amount of the first color temperature estimation information is insufficient estimating the color temperature of the light source based on the first and second color temperature estimation information; and adjusting the first frame data based on the estimated color temperature.

Abstract: An apparatus and method for encoding audio data with a small amount of computation are provided. The audio data encoding apparatus includes: a time-to-frequency converting unit that receives a time domain audio signal and converts the same to a frequency domain audio signal; a spectral processor that performs spectral processing on the frequency domain audio signal; a masking threshold calculator that calculates an energy level for each frequency band of the frequency domain audio signal, approximates an energy distribution curve connecting the calculated energy levels to a distribution pattern similar to that of noise threshold levels calculated by a conventional psychoacoustic model, and calculates a scalefactor band gain for each band; and a quantization noise curve adjuster that adjusts a common gain to meet a target bit rate and matches a quantization noise curve to the approximated energy distribution curve while fixing the scalefactor gain for each frequency band.
