Patent number: 8340368Abstract: The present invention relates to a face detection system for a vehicle. At least one first lighting unit is configured to radiate infrared light onto a left side of a driver's face. At least one second lighting unit is configured to radiate infrared light onto a right side of the driver's face. An image capturing unit separately captures the driver's face onto which the infrared light is radiated from the first and second lighting units. A control unit acquires left and right images of the face from the image capturing unit, and obtains a difference image between the acquired left and right images, thus determining whether the driver is inattentive in looking ahead. The system stably performs the face detection function with no or less effect by external optical environments as well as reduced computational load.Type: GrantFiled: December 29, 2008Date of Patent: December 25, 2012Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Byoung Joon Lee, Eui Yoon Chung

Patent number: 8057593Abstract: The present invention relates to a pigment dispersion and a black water-reducing agent, more particularly, to a pigment dispersion comprising a carbon black whose surface is modified with an aminosilane compound and a polycarboxylic acid-based water-reducing agent, and a black water-reducing agent using the same. The present invention is characterized in that the surface-modified carbon black with an aminosilane compound is water-dispersed by using a polycarboxylic acid-based water-reducing agent as a dispersing agent having better performance than a naphthanlene-based water-reducing agent. Therefore, the present invention can display black color of the water-reducing agent and cement at the same time and improve the flowability of cement owing to the presence of carbon black in the form of nanoparticles, which enables to manufacture ultrahigh strength concrete.Type: GrantFiled: March 3, 2011Date of Patent: November 15, 2011Assignee: OCI Company LtdInventors: Hae Yoon Ryu, Kwang Eui Yoon, Sang Je Cho, Moo Soo Park, Yo Bok Park, Se In Yang
