  • Patent number: 11873176
    Abstract: An Urban Intermodal Freight System is capable of transporting large volumes and tonnage of freight by containerized or other means on a mass transit rail system. It captures excess capacity in the existing mass transit rail infrastructure to move packages, parcels, and freight by using miniaturized intermodal cargo containers that are designed to integrate seamlessly with the existing transit infrastructure, while displacing delivery trucks from increasingly crowded city streets. By enabling inbound trucks to transfer their cargo to the Urban Intermodal Freight System at a city's outskirts, freight is delivered without trucks entering congested downtown areas, greatly alleviating traffic congestion, delays, greenhouse gas emissions and other negative environmental impacts. The Linear Loading Dock and Conveyor System may have other useful applications, for example to access a facility, building or vehicle, or in other circumstances where off street truck parking or loading docks are not available.

  • Patent number: 11351969
    Abstract: A tractor vehicle operation control device includes a yaw rate sensor, which detects the actual yaw rate, and a controller, which executes damping control for increasing braking power on the vehicle wheels based on the actual yaw rate and damping periodic yaw motion of the tractor vehicle originating in a trailer. The controller, based on the actual yaw rate, calculates a yaw indicator representing the degree of yaw motion, and sets the front wheels braking power to be greater and sets the rear wheels braking power to be less as the yaw indicator increases. For example, the controller calculates a peak value of the actual yaw rate and determines the actual yaw rate peak value to be the yaw rate. The controller also may calculate yaw angular acceleration based on the actual yaw rate and determine a yaw indicator based on the peak value of the yaw angular acceleration.

  • Patent number: 11329483
    Abstract: A system for feeding electric power to a first consumer (1) comprises an input filter (6) with an input configured to be connected to a DC energy source and a DC intermediate link (3) connected to an output (14) of the input filter. A converter (12) is with an input connected to the DC intermediate link and has an output to be connected to said first consumer (1). The unit (16) controls the converter to obtain feeding of electric power requested by the first consumer independently of variations of the voltage on the DC link (3). An assembly is configured to act stabilizing on that voltage by controlling the converter to add a first power component to the power to be fed to the consumer. A second consumer (19) is controlled to consume a second power component to either assist the control of the converter to obtain the stabilization or alone take care thereof.
