Abstract: Methods, systems, and computer programs are presented for monitoring tailgating when a vehicle follows another vehicle at an unsafe distance. A method for enhancing a Following Distance (FD) machine learning (ML) model is disclosed. The method includes providing a management user interface (UI) for configuring FD parameters, followed by receiving FD events. A UI for manual FD annotation and another for customer review of filtered FD events are also provided. Annotations and customer review information are collected to improve the training set for the FD ML model. The FD model is then trained with the new data and downloaded to a vehicle. Once installed, the FD model is utilized to detect FD events within the vehicle, thereby enhancing the vehicle's safety and performance in driving scenarios by improving the accuracy and reliability of FD event predictions or detections.

Abstract: Methods, systems, and programs are presented for detecting impaired views in monitoring cameras. One method includes training a rotation classifier with unsupervised learning utilizing a first set of images. The rotation classifier is configured to receive an input image and generate a rotation feature embedding for the input image. In addition, the method includes training an impairment classifier with supervised learning utilizing a second set of images, impairment labels for each of the second set of images, and the rotation feature embedding, generated by the rotation classifier, for each of the second set of images. The method further includes accessing a vehicle image captured by a camera on a vehicle, and providing the vehicle image to the impairment classifier as input, and the impairment classifier outputs a camera impairment from a set of camera impairment categories. Further, the vehicle image and the camera impairment are presented on a user interface.

Abstract: A structure for fixing an aiming device includes a fixing base, a rotatable disk, a locking bolt, and two elastic components. The fixing base is departably attached to the gun. The rotatable disk is rotatably disposed at a bottom of the fixing base and has two wedge-shaped components. Each of the wedge-shaped components has a slope with a higher end having a position-fixing concave. The locking bolt has position-fixing blocks. When the higher ends of the two wedge-shaped components are moved to the underneath of the locking bolt, the locking bolt is pushed upward into the fixing slot of the gun and the position-fixing blocks are placed into the position-fixing concaves. When the lower ends of the two wedge-shaped components is moved to the underneath of the locking bolt, the locking bolt is pushed downward by the two elastic components and thus departed from the fixing slot of the gun.
