Abstract: A vehicle drive assist system includes: a lane line recognizing unit that recognizes left and right lane lines defining a lane along which a vehicle equipped with the drive assist system travels; and a drive assist unit that sets lane departure determination thresholds along the left and right lane lines, and performs a drive assist operation based on a relative position of the vehicle to the lane departure determination threshold. The drive assist unit sets a left lane departure determination threshold on the basis of an inner edge of unmelted snow when a left lane line of a traveling lane is recognized based on a front-view image of the vehicle, captured by the lane line recognizing unit, but a right lane line which is covered with the unmelted snow cannot be recognized.

Abstract: When a stereo image recognition device detects a vehicle ahead, a driving support apparatus extracts the vehicle ahead as a vehicle against which control should be performed, and performs driving support control based upon the information from the stereo image recognition device. When the stereo image recognition device does not detect the vehicle ahead, the driving support apparatus sets either one of the distance from the driving lane on which the vehicle travels and a start point of a curve ahead according to the configuration of the road ahead and a detection limit distance of the information of the vehicle ahead by the stereo image recognition device (front recognition device) as a threshold value IVC_L. When the vehicle ahead is present distant by more than the threshold value IVC_L, the driving support apparatus performs driving support control based upon the information by the inter-vehicle communication from a communication device.

Abstract: An information processing unit displays a pop-up window in a display area of a display unit when the own vehicle is in an area of a set distance or less away from an extracted intersection, when the own vehicle stops, when a brake switch is ON, and when a display request for an image of traffic conditions of vehicles at the intersection by the driver is recognized. If an accelerator operation is performed in a predetermined way after the pop-up window is displayed, the display of the pop-up window is finished.

Abstract: A rotational coupling device for a cordless dental instrument including a motor housing which has a pair of semi-annular projections integrally provided at a rear end thereof with a pair of arc-shaped recesses formed between the coupling projections and semi-annular slot provided around the inner peripheries of the semi-annular projections. A battery housing has a pair of semi-annular around an outer periphery adjacent its front end, a pair of arc-shaped projections coinciding with the arc-shaped recesses of the motor housing and a pair of semi-annular flanges coinciding with the pair of semi-annular projections of the motor housing so as to form a rotational coupling between the motor housing and the battery housing. An insulating disc having a pair of contacts connected to a motor fits into a rear opening of the motor housing.
