Abstract: A compound Chemical Formula 1: wherein: each X is independently N, CH, or CD, provided that two or more of X are N, L is a single bond, or a substituted or unsubstituted C6-60 arylene, Ar1 and Ar2 are each independently a substituted or unsubstituted C6-60 aryl, Ar3 and Ar4 are each independently phenyl that is unsubstituted or substituted with at least one deuterium, any one of Ar1 to Ar4 is substituted with cyano, HAr is pyrimidinyl which is unsubstituted or substituted with 1 to 3 substituent groups each independently selected from among deuterium, a substituted or unsubstituted C1-60 alkyl, and a substituted or unsubstituted C6-60 aryl; triazinyl which is substituted with two substituted or unsubstituted C6-60 aryls; or quinazolinyl substituted with one substituted or unsubstituted C6-60 aryl, and the other substituents are as described in the specification, and an organic light emitting device comprising the same.

Abstract: An electronic throttle control system is provided, which comprises an accelerator pedal position sensor, a control unit, and a biasing mechanism. The accelerator pedal position sensor detects a position of an accelerator pedal. The throttle actuator actuates a throttle valve to rotate. The control unit determines a target throttle position based on the accelerator pedal position, and controls an operation of the throttle actuator in accordance with the determined target throttle position. The biasing mechanism provides rotational force to the throttle valve such that an opening angle of the throttle valve while the throttle actuator is not powered is greater than a predetermined idle opening angle.
