A pelvis assembly for a dummy includes a pelvic plate attached to a lumbar region of the dummy, and one of more pelvic units, attached to the pelvic plate to transmit motion from a femur bar of the dummy to the plate. Each pelvic unit includes a hip joint, attached to the femur bar; a rotary axle, a first end of which is attached to the hip joint, and which is disposed laterally, to rotate together with the hip joint when the femur bar pivots vertically; and one or more pelvic angle adjusters, installed near a second end of the rotary axle, to transmit rotation of the rotary axle to the pelvic plate, thereby changing a vertical angle of the pelvic plate.

An apparatus for adjusting a position of the vertebral column of a dummy model for estimating the feeling of sitting in a seat almost exactly mimics the characteristics of the vertebral joints of a human being. The apparatus comprises a pelvic plate; a plurality of lumbar joints, stacked on the pelvic plate so as to be spaced apart from each other, and having joint springs installed in front and rear portions thereof centered around a rotation center interconnecting two adjacent ones thereof; femur joints rotatably installed below the pelvic plate, and connected with one end of each femur bar; and pelvic pivoting members transmitting rotating force of the femur joints, which is caused by vertical pivoting of the femur bars, to the pelvic plate, and changing a vertical angle of the pelvic plate.

According to the present invention, a method for searching for information using the Web and a method for voice conversation using same involve generating a basic word vector for at least one of a provided user query and a language analysis result; using the basic word vector, searching a vector space database for a vector space corresponding to the basic word vector; searching, if a similarity between the basic word vector and the found vector space is lower than a preset reference, a vector space database for a vector space corresponding to an expanded word vector using the expanded word vector generated from the result of the Web search performed using at least one of the user query and the language analysis result; and searching for knowledge information on the basis of the vector space found in the basic searching step or the expanded searching step. Thus, improved research results may be provided in response to the user query.

The present invention provides a polyurethane foam for an automobile steering wheel. More particularly, the present invention relates to polyurethane foam formed by using a predetermined amount of a polyol having various functional groups and OH values and a predetermined amount of isocyanate having a certain function, along with water as a foaming agent, thereby preventing the environmental problems caused by use of the conventional fluorine-based or pentane-based foaming agent and also improving durability such as water resistance.
摘要:
A human dummy system for evaluating the comfort of a seat comfort includes sensor units and a data processing unit. The sensor units are attached to the relevant joints of a human dummy, and detect the angles of the relevant joints. The data processing unit calculates information about relative locations of adjacent joints on the basis of the information about the angles of the relevant joints, and calculates the absolute location of a specific joint through coordinate system transformation between the information about relative locations and the joints of the human dummy.
摘要:
The present invention relates to a polyamide resin composition and, more particularly, to a polyamide resin composition for an automobile radiator, prepared by mixing a polyamide resin, prepared by mixing a polyamide 66 resin having excellent mechanical strength and heat resistance with a polyamide 612 resin having excellent chemical resistance, a glycidyl reactive compatibilizer, glass fiber coated with a silane-based coupling agent, amine and silane-based crosslinking agents, phenol- and phosphate-based antioxidants, an imide hydrolysis resistance agent, and a montan-based lubricant in a predetermined ratio, thus improving heat resistance and chemical resistance simultaneously and maintaining equivalent properties to those of conventional polyamide resin compositions.
