Publication number: 20230415840Abstract: Disclosed are various embodiments of a tilting frame for a three-wheeled vehicle with a steerable load-carrying front end. When the vehicle is rolling forward and steered, the wheels and portions of the frame can tilt sideward in a controlled manner to provide turning stability. Further, the frame keeps the load in a substantially-level and fully supported while also causing the vehicle and load center of gravity to shift laterally to enhance vehicle stability. An embodiment of the invention relates to human pedaled and electric-assisted vehicles including cargo bikes and trishaws for carrying passengers.Type: ApplicationFiled: March 11, 2023Publication date: December 28, 2023Inventor: Robert Frank Hoskin

Patent number: 9631776Abstract: Systems and methods are provided for controlling a selective catalyst reduction (SCR) system having a SCR reactor. A reductant slip set point indicative of a target slip is received as a control variable is to be utilized for maintaining an amount of a NOx composition included in a combustion gas below a selected limit. A signal transmitted by a sensor is received, and is indicative of the reductant slip downstream of the SCR reactor. An amount of a NOx reductant to be introduced to the SCR reactor is determined based, at least in part, on a relationship between the target reductant slip and the reductant slip downstream of the SCR reactor indicated by the signal. A control signal is transmitted to cause introduction of the amount of the NOx reductant to the SCR reactor to maintain the amount of the NOx composition in the combustion gas below the selected limit.Type: GrantFiled: November 7, 2012Date of Patent: April 25, 2017Assignee: GENERAL ELECTRIC COMPANYInventor: Robert Frank Hoskin
