Abstract: A method for detecting a source of a misfire for an engine having turbulent jet ignition (TJI) during a service routine is presented. A diagnostic tool is coupled to an engine controller of the TJI engine. An increase in revolutions per minute (RPM) of the TJI engine is commanded. An engine roughness is measured and a baseline engine roughness for the TJI engine while all cylinders are in an active state is established. A first main spark plug is commanded to deactivate. A first test engine roughness of the TJI engine is measured based on the first main spark plug being deactivated. The baseline engine roughness is compared to the first test engine roughness. A determination is made, based on the comparison, whether the first pre-chamber is fouled.

Abstract: System and method are provided to detect objects in a scene frame of two-dimensional (2D) video using image processing and determine object image coordinates of the detected objects in the scene frame. The system and method deploy a virtual camera in a three-dimensional (3D) environment to create a virtual image frame in the environment and generate a floor in the environment in a plane below the virtual camera. The system and method adjust the virtual camera to change a height and angle relative to the virtual image frame. The system and method generate at an extended reality (XR) coordinate location relative to the floor for placing the detected object in the environment. The XR coordinate location is a point of intersection of a ray cast of the virtual camera through the virtual frame on the floor that translates to the image coordinate in the virtual image frame.

Abstract: Provided is a semi-active seat suspension system that minimizes vibration and energy transmission from a vibration/energy source, such as a motor vehicle, to a seated occupant by means of a spring and computer-controlled damper suspension system. Using a variety of sensors to determine an ideal damping rate at a given point in time, the system adjusts the damping rate in real time to provide the best possible ride to the occupant given the constraints of the system.
