Abstract: A system includes a variable choke coupled to a barrel of a shot gun, and a mechanical mechanism coupled to the variable choke and configured to adjust an amount of choke constriction of the variable choke. The system further includes a motor coupled to the mechanical mechanism, and a control system configured to determine a desired size of a shot cone of shot fired from the shot gun, determine a choke constriction position of the variable choke that produces the identified size of the shot cone, and apply control signals to the motor to cause, via movement of the mechanical mechanism, automatic adjustment of the variable choke based on the determined choke constriction position of the variable choke.

Abstract: A system includes multiple cameras directed to capture images or video of a passenger offloading area associated with a facility, where the passenger offloading area comprises multiple offloading areas that enable multiple autonomous vehicles to offload vehicle occupants. The system receives images or video, from the multiple cameras, of the passenger offloading area, and analyzes the images or video to identify autonomous vehicles of the multiple autonomous vehicles that have completed passenger offloading and have departed respective offloading areas. The system instructs, based on the image or video analysis, the multiple autonomous vehicles to transit through the passenger offloading area in a coordinated manner, including stopping at a selected one of the multiple passenger offloading areas, to offload the vehicle occupants.
