Abstract: A computer system calibrates an image from digital motion video, which originated from a camera that has a view of a scene from a period of time, with an image rendered from a three-dimensional model of the scene for a view based on a location (position and orientation) of the camera in the scene. The calibrated image from the digital motion video can be overlaid on the rendered image in a graphical user interface. The graphical user interface can allow a user to modify opacity of the overlay of the calibrated image from the digital motion video on the rendered image. The overlaid image can be used as a guide by the user to provide inputs with respect to the three-dimensional model.

Abstract: An electrical relay (2) includes an electromagnetic drive system for providing bi-directional drive. The electrical relay (2) includes a first a coil (212) and a second coil (213). A current is supplied to the coils (212) and (213) in opposite directions. The two coils (212) and (213) can be used to accelerate the armature in either direction in relation to the two contacts.

Abstract: The present subject matter provides various technical solutions to technical problems facing sensor-based vehicle safety technology. To address problems facing identification of safety features (e.g., safety sensors) for a particular vehicle, a vehicle safety feature identification system may be used to identify a vehicle and the safety features that are installed on that vehicle. To address problems facing identification of which safety sensors require maintenance, a vehicle safety feature maintenance system may be used to identify vehicle safety sensors based on information received about one or more vehicle repairs, such as structural repairs following a vehicle collision. The vehicle safety feature maintenance system may use image data or other inputs to identify a vehicle repair area, identify other vehicle components that must be removed or adjusted to complete the vehicle repair, and identify all vehicle safety sensors and other safety features that will need to be repaired, replaced, or recalibrated.
