Patent number: 11673487Abstract: A passenger identification apparatus for vehicles is provided to identify a passenger through integration of a sensor that senses change in permittivity and a sensor that senses change in pressure. The apparatus includes a permittivity change sensing unit that is installed in the seat and senses change in capacitance generated by permittivity of the passenger seated on the seat and a pressure change sensing unit that is installed in the seat and senses change in pressure generated by a load of the passenger seated on the seat. A controller adjusts power supplied to the permittivity change sensing unit and the pressure change sensing unit and determines whether the passenger is seated on the seat and the type of passenger using permittivity and pressure change values sensed by the permittivity change sensing unit and the pressure change sensing unit.Type: GrantFiled: October 3, 2019Date of Patent: June 13, 2023Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Pyoung Sik Shin, Chun Seok Park

Patent number: 7614314Abstract: An apparatus for classifying a vehicle occupant to determine whether to deploy an airbag is disclosed. The classification apparatus includes a sensor which is installed in a seat of a vehicle and is supplied with AC power, the sensor having a sensing conductor and a guard conductor electrically connected to each other, with an insulator interposed therebetween. A controller compares an imaginary current value, attributable to variation in capacitance of the sensor, measured on an output side of the sensor, and a real current value, attributable to variation in resistance of the sensor, with preset threshold values, thus classifying an occupant who is sitting in the seat. According to the classification apparatus, even if moisture permeates into a seat, an occupant can be precisely classified using the real current value and the imaginary current value.Type: GrantFiled: January 10, 2008Date of Patent: November 10, 2009Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Chun Seok Park, Jae Haeng Yoo

Publication number: 20090042495Abstract: Disclosed herein is a rotary-type polishing device having protrusion members. The rotary-type polishing device includes a rotary shaft, a disc-type body, an elastic rubber, and a plurality of protrusion members. The disc-type body is coupled with the rotary shaft and is configured to integrally rotate together with the rotary shaft. Furthermore, the disc-type body has a concavely curved outer surface, which is formed on the underside of the outer circumferential surface thereof. The elastic rubber, having a predetermined thickness, is attached to the outer surface and conforms to the shape of the outer surface. The protrusion members are attached to or partially embedded in the rubber.Type: ApplicationFiled: March 14, 2008Publication date: February 12, 2009Inventors: Bong Won CHO, Hyung Chul Cho, Chun Seok Park
