Patent number: 8800533Abstract: A system and method for preventing knocking prevents knocking by injecting a sub fuel including ethanol having high octane number to a combustion chamber in a case that the knocking occurs. The system for preventing knocking may include a cylinder, a piston moving in the cylinder reciprocally, forming a combustion chamber with the cylinder, and having a central axis, a first injector mounted at an upper surface of the cylinder with a distance from the central axis of the piston, and directly injecting a main fuel including gasoline into the combustion chamber, a second injector mounted at the upper surface of the cylinder on the central axis of the piston, and directly injecting a sub fuel including ethanol into the combustion chamber, and a spark plug disposed at the upper surface of the cylinder near the second injector.Type: GrantFiled: September 19, 2011Date of Patent: August 12, 2014Assignee: Hyundai Motor CompanyInventor: Je Hyung Lee

Patent number: 6091031Abstract: A portable information terminal is provided. The terminal includes a touch screen panel having an activation area and an activating unit. The activation unit activates the portable information terminal when the terminal is turned off and an activating position on the activation area is pressed for a predetermined time. The activating unit contains a press position sensor, a press timer, and a controller. The press position sensor senses if a panel position on touch screen panel is pressed and determines a location of the panel position on the touch screen panel to generate corresponding press position data. The press timer determines if the panel position is pressed for at least a predetermined time to generate corresponding press time data.Type: GrantFiled: February 6, 1998Date of Patent: July 18, 2000Assignee: Samsung Electronics Co., Ltd.Inventors: Je-hyung Lee, Jae-seong Oh, Jin-chul Lee
