摘要:
In general, the disclosure describes an RFID tag designed such that the tag is both covert and not easily blocked from the interrogation signal by the hand or other body part of a person. In particular, the RFID tag is designed to have a long, narrow aspect that allows placement of the tag in locations on or in a book that are inconspicuous to the casual observer while extending beyond a hand of a person holding the book by the spine on or near a geometry centerline. The RFID tag includes a dipole segment and a loop segment coupled to the dipole segment. The loop segment of the modified dipole antenna provides the antenna with larger signal strength than conventional dipole antennas. Moreover, the conductive loop segment also provides improved impedance matching capabilities to allow the modified dipole antenna to match the impedance of an integrated circuit (IC) chip of the RFID tag.

A method of reconstructing a three-dimensional (3D) facial shape with super resolution even from a short moving picture having a front facial image by acquiring a super-resolution facial image by applying, as a weighting factor, a per-unit-patch similarity between a target frame and frames remaining after excluding the target frame from among a plurality of continuous frames including the front facial image, and reconstructing the 3D facial shape based on the acquired super-resolution facial image.

In an exemplary implementation of this invention, light from a scattering scene passes through a spatial light attenuation pattern and strikes a sensor plane of a camera. Based on said camera's measurements of the received light, a processing unit calculates angular samples of the received light. Light that strikes the sensor plane at certain angles comprises both scattered and directly transmitted components; whereas light that strikes at other angles comprises solely scattered light. A processing unit calculates a polynomial model for the intensity of scattered-only light that falls at the latter angles, and further estimates the direct-only component of the light that falls at the former angles. Further, a processing unit may use the estimated direct component to calculate a reconstructed 3D shape, such as a 3D shape of a finger vein pattern, using an algebraic reconstruction technique.

Disclosed is a cooling apparatus for a semiconductor component having a coolant inlet flow path on a coolant flow path connecting a coolant inlet and a coolant outlet, the coolant inlet flow path having a diffuser shape, in which its cross-sectional area increases from a coolant inlet to a portion where cooling fins start to appear. In the cooling apparatus, the coolant inlet flow path meets the following equation: ω=D{3/2+sin(α(x−A))}. Here, ω is the radius of the diffuser, D is the diameter of the coolant inlet, x is a distance from the coolant inlet toward the cooling fins, α is an expansion slope coefficient of the diffuser in radians, and the sine of (α·A) is 1.In the cooling apparatus for a compact and integrated semiconductor component, since the diffuser-shaped coolant inlet flow path extending from the coolant inlet to the cooling fins is designed in an optimal shape, it is possible to improve cooling efficiency and to reduce flow resistance to coolant flow.

Disclosed herein is a door for traditional Korean houses. The door includes a structure of a lattice door framed with vertical lattice frames and horizontal lattice frames which are arranged in a regular periodic pattern. A lattice width-to-height ratio (W/H) of the lattice door ranges from 0.07 to 0.1 so that the outside air is prevented from entering the interior of a room through the lattice door to minimize heat loss from the interior of the room to the outside air. Therefore, the present invention can satisfy the basic function of insulating the interior of the room born the outside air. Thereby, energy consumption can be reduced.
