Abstract: Vertical take-off and landing (VTOL) aircraft can provide opportunities to incorporate aerial transportation into transportation networks for cities and metropolitan areas. However, VTOL aircraft can be sensitive to uneven weight distributions, e.g., the payload of an aircraft is primarily loaded in the front, back, left, or right. When the aircraft is loaded unevenly, the center of mass of the aircraft may shift substantially enough to negatively impact performance of the aircraft. Thus, in turn, there is an opportunity that the VTOL may be loaded unevenly if seating, luggage placement, and/or positions of internal components are not coordinated. Among other advantages, dynamically assigning the payloads and adjusting components of the VTOL aircraft can increase VTOL safety by ensuring the VTOL aircraft is loaded evenly and meets all weight requirements; can increase transportation efficiency by increasing rider throughput; and can increase the availability of the VTOL services to all potential riders.

Abstract: A flatbed weigh system and methods for weighing substantially flat articles such as mail flats while they are moving. A weigh system has an intake plate (2102) and an accelerator assembly (2100) that receives an article (2150) and accelerates it to a selected velocity. Acceleration is controlled by a servo motor (2112) which in turn is driven by a precision closed-loop servo system (FIG. 12) that accumulates motor torque data to determine the article weight. The accelerator assembly uses vacuum pressure (2130, 2132) to hold the moving article in engagement with a cylindrical capstan roller (2110) while it is being weighed. This vacuum-driven concept eliminates the need for a pinch roller to hold the moving article against a capstan roller as in other designs. Because the pinch roller is eliminated, there is essentially no “bouncing” to address, so dampen is obviated. Further, the vacuum design is not adversely affected by variations in thickness of the article under test as in the pinch roller designs.

A weigh system has an intake plate (2102) and an accelerator assembly (2100) that receives an article (2150) and accelerates it to a selected velocity. Acceleration is controlled by a servo motor (2112) which in turn is driven by a precision closed-loop servo system (FIG. 12) that accumulates motor torque data to determine the article weight.

Further, the vacuum design is not adversely affected by variations in thickness of the article under test as in the pinch roller designs.

Abstract: A technique for recording the front image of vehicles which violate the regulation in the axle weight is desired. In general, the weight of the leading axle cannot be excessively heavy, so that the over weight axle is a second or more rear side axle. Further, the distance between an axle weight detector and a vehicle detector for taking a vehicle image is normally below 8 meters. Under these conditions, when the over weight axle is detected, the over axle weight vehicle is predicted to be a vehicle being presently detected, a vehicle to be detected next, or next to the next. From the images of those vehicles, vehicles having no possibility of violating the axle weight regulation are eliminated based on a license plate read from the vehicle image or the measured vehicle height. The images not eliminated are stored as over axle weight vehicle images.
