Abstract:
A method of estimating a time to collision (TTC) of a vehicle with an object comprising: acquiring a plurality of images of the object; and determining a TTC from the images that is responsive to a relative velocity and relative acceleration between the vehicle and the object.
Abstract:
An imaging system for a vehicle may include a first image capture device having a first field of view and configured to acquire a first image relative to a scene associated with the vehicle, the first image being acquired as a first series of image scan lines captured using a rolling shutter. The imaging system may also include a second image capture device having a second field of view different from the first field of view and that at least partially overlaps the first field of view, the second image capture device being configured to acquire a second image relative to the scene associated with the vehicle, the second image being acquired as a second series of image scan lines captured using a rolling shutter. As a result of overlap between the first field of view and the second field of view, a first overlap portion of the first image corresponds with a second overlap portion of the second image. The first image capture device has a first scan rate associated with acquisition of the first series of image scan lines that is different from a second scan rate associated with acquisition of the second series of image scan lines, such that the first image capture device acquires the first overlap portion of the first image over a period of time during which the second overlap portion of the second image is acquired.
Abstract:
A conjugate comprising L-DOPA covalently linked to at least one γ-aminobutyric acid (GABA) moiety, an ester and/or an addition salt thereof are disclosed, as well as uses thereof for treating a neurodegenerative disease or disorder.
Abstract:
A method is provided using a system mounted in a vehicle. The system includes a rear-viewing camera and a processor attached to the rear-viewing camera. When the driver shifts the vehicle into reverse gear, and while the vehicle is still stationary, image frames from the immediate vicinity behind the vehicle are captured. The immediate vicinity behind the vehicle is in a field of view of the rear-viewing camera. The image frames are processed and thereby the object is detected which if present in the immediate vicinity behind the vehicle would obstruct the motion of the vehicle. The processing is preferably performed in parallel for a plurality of classes of obstructing objects using a single image frame of the image frames.

Abstract:
A navigation system may include at least one processing device configured to determine, based on an output of one or more position sensors associated with the navigation system, a current location of at least one component associated with the navigation system and determine a destination location different from the current location. The navigation system may also acquire, from one or more image acquisition devices, a plurality of images representative of an environment of a user of the navigation system and derive, from the plurality of images, visual information associated with at least one object in the environment. The system may also determine one or more instructions for navigating from the current location to the destination location, wherein the one or more instructions include at least one reference to the visual information derived from the plurality of images. The system may also deliver to the user the one or more instructions.
Abstract:
A camera mount for mounting a camera inside a windshield of a vehicle. The camera includes a lens mount and a camera housing. The front tip of the lens mount is constrained to be in close proximity to or constrained to contact the inside of the windshield for different rake angles of the windshield.
Abstract:
Systems and methods use cameras to provide autonomous navigation features. In one implementation, a driver-assist object detection system is provided for a vehicle. One or more processing devices associated with the system receive at least two images from a plurality of captured images via a data interface. The device(s) analyze the first image and at least a second image to determine a reference plane corresponding to the roadway the vehicle is traveling on. The processing device(s) locate a target object in the first two images, and determine a difference in a size of at least one dimension of the target object between the two images. The system may use the difference in size to determine a height of the object. Further, the system may cause a change in at least a directional course of the vehicle if the determined height exceeds a predetermined threshold.
