Abstract: An antenna is disclosed wherein a plurality of antennas are combined in a single housing, whereby antenna radiation performance can be improved by increasing frequency bandwidth while minimizing signal interference between antennas. The antenna has a case, a housing, a circuit board, and a base. The case has an open bottom. The housing, formed in a shape corresponding to the interior surface of the case and inserted into the interior of the case, has a plurality of radiating bodies that send and receive signals in a plurality of frequency bands, and a coupling patch that increases frequency bandwidth and minimizes signal interference between radiating bodies. The board is mounted in the case and whereon a feeding pad is furnished that is electrically connected to the radiating bodies. The base is mounted on the board so as to couple to the case and block to open bottom of the case.

Abstract: A haptic system includes: at least one bio-signal measuring unit configured to measure a bio-signal from a user in response to visual information; at least one haptic information providing unit equipped on the user and configured to provide haptic information; and a controller configured to operate the haptic information providing unit when there is a change in the bio-signal. The haptic device does not require calibration, so that a user can use the haptic system conveniently in any environment. In addition, the user's location and action can be determined accurately.

Abstract: Disclosed is an external mounting type microchip dual band antenna assembly including a microchip dual band antenna connected to a printed circuit board which is disposed in a case of a portable terminal. The microchip dual band antenna comprises upper and lower patch elements respectively surrounding lengthwise upper and lower ends of a dielectric body having a shape of a quadrangular prism; a first radiation patch placed on a front surface of the dielectric body to extend zigzag from the upper patch element toward the lower patch element; a second radiation patch placed on a rear surface of the dielectric body to extend zigzag from the upper patch element toward the lower patch element in a manner such that zigzag configurations of the first and second radiation patches are staggered with each other; and a feeder channel defined on a side surface of the dielectric body adjacent to the lower patch element and plated in such a way as to connect the first and second radiation patches with each other.

Abstract: Disclosed is a microchip dual band antenna mounted to a printed circuit board having a ground surface and a non-ground surface. The microchip dual band antenna comprises first and second patch elements respectively surrounding both lengthwise ends of a dielectric body having a shape of a quadrangular prism; a first radiation patch separated from the first patch element and placed on an upper surface of the dielectric body to extend zigzag toward the second patch element; a second radiation patch joined to the second patch element and placed on a lower surface of the dielectric body to extend zigzag toward the first patch element by a distance less than one half of an entire length of the dielectric body, in a manner such that zigzag configurations of the first and second radiation patches are staggered with each other; and a first feeder channel defined on a front surface and adjacent to one end of the dielectric body and plated in such a way as to connect the first and second radiation patches.

Abstract: Disclosed is a reverse rotation preventing apparatus for a fishing reel, which is capable of allowing a handle of a spinning reel to be rotated in a forward direction to wind a fishing line, capable of preventing the handle from being rotated in a backward direction to unwind the fishing line, and is capable of minimizing a rotational resistance of the handle. The reverse rotation preventing apparatus includes a plurality of rollers. These rollers are inserted into an inner periphery surface of an outer race and thereafter they are fitted between an inclined surface and an outer periphery surface of a sleeve during the rotation of a handle in the backward direction. The roller supporters include a magnetic material and a nonmagnetic material. The magnetic material faces in the backward rotational direction of the fishing reel. The nonmagnetic material faces in the forward rotational direction of the fishing reel.
