Abstract: A device for operating a horn of a vehicle includes: a horn operation cover covering a top portion and a circumference of an airbag module mounted on a frame of a steering wheel of the vehicle, the horn operation cover configured to be moved downward or upward; a conductive plate spring having one end fixed to the frame and another end in contact with the horn operation cover; and a conductive contact terminal disposed under the plate spring such that a contact between the contact terminal and the plate spring is possible. When the horn operation cover is moved downward so as to press the other end of the plate spring, the plate spring electrically contacts the contact terminal, thereby operating the horn.

Abstract: Disclosed is an external airbag apparatus. The apparatus includes, a back beam disposed on one surface directed toward a bumper on which an airbag module is disposed. The apparatus additionally includes a deployment guide disposed between the bumper and the back beam, both ends of which are coupled to the back beam, and a middle end of which is supported on the bumper. Furthermore, the apparatus includes a sensor disposed between the deployment guide and the back beam to sense impact when pressed by the deployment guide during impact to the bumper.

Abstract: An external airbag cushion including: an outer cover that inflates to cover the front of a bumper of a vehicle; a plurality of separation walls that are disposed inside outer cover to divide the inside into a plurality of chambers in the transverse direction of the vehicle; and low-pressure variable vents and high-pressure variable vents that are disposed for the chambers, respectively, and selectively open, depending on the internal pressure of the chambers.

Abstract: An exterior airbag cushion for a vehicle includes a cushion body which is deployed forward from a front end of the vehicle, a vent hole which is formed in the cushion body, and a variable guide which has a cover shape and covers the vent hole in such a way that a first end and opposing side edges of the variable guide are fastened to the cushion body, and a second end thereof is open to form an opening. The variable guide is folded and is brought into close contact with the cushion body and temporarily fastened to the cushion body so that the variable guide guides a direction of gas discharged from the vent hole and the opening when a temporary fastening structure is loosened by internal pressure of the cushion body.

Abstract: An external airbag structure for a vehicle includes an airbag cushion disposed to develop toward a front side of a bumper from a folded state, a vent hole formed at the airbag cushion, and a variable vent cover attached to the airbag cushion to block the vent hole, wherein the variable vent cover includes a material having a heat-resisting property which is melted and torn by a temperature and/or a pressure of an internal expansion gas of the airbag cushion on expansion of the airbag cushion. The vent hole is opened to perform an effective cushion action as the airbag cushion is developed.

Abstract: Disclosed is a method of diagnosing the chances of pregnancy and the diagnostic kit for the method. In the present invention, follicular fluid is retrieved from the women who attended the in vitro fertilization program and matrix metalloproteinase activity is measured. According to the present invention, the chance of pregnancy in the group with low matrix metalloproteinase-9 activity is zero whereas in the group with high matrix metalloproteinase-9 activity, the chances are 50-60%. Therefore it is possible to predict the chances of pregnancy in assisted reproduction technology by measuring the degree of matrix metalloproteinase-9 expression by using the method and kit of the present invention enhancing the efficiency of assisted reproduction technology.

Abstract: Disclosed is a method of diagnosing the chances of pregnancy and the diagnostic kit for the method. In the present invention, follicular fluid is retrieved from the women who attended the in vitro fertilization program and MMP activity is measured. According to the present invention, the chance of pregnancy in the group with low MMP-9 activity is zero whereas in the group with high MMP-9 activity, the chances are 50-60%. Therefore it is possible to predict the chances of pregnancy in ART by measuring the degree of MMP-9 expression by using the method and kit of the present invention enhancing the efficiency of ART.
