Abstract: Systems and methods preventing vehicle runaway of an electric powersport vehicle in an emergency situation are provided. One method comprises receiving, via an emergency shutoff switch of the electric powersport vehicle or via a tether switch of the electric powersport vehicle, a signal indicating an existence of the emergency situation while the electric powersport vehicle is in motion, and in response to the signal, attempting to regulate an operation of an electric motor configured to propel the electric powersport vehicle to cause regenerative braking of the electric motor while the electric powersport vehicle is in motion.

Abstract: There is disclosed a diazotype copier for deodorizing developed diazocopy material. The copier includes a light source for exposing the diazotype copy material and a developing chamber for developing the exposed copy material. After exiting the developing chamber, the developed material passes under a heating chamber which includes a heating element and means for providing a flow of air into the chamber, around the heating element, and across the developed copy material. The heating air releases the entrapped ammonia vapors from the developed copy material. Thereafter, the air, including the released ammonia vapors, flows toward and into a scavenging device which neutralizes the ammonia vapors.
