Abstract: Devices, systems, and methods for controlling microbial contamination of scooters are disclosed. A method may include determining that a user interaction with a vehicle is complete, presenting a first indication that the vehicle is unavailable for use, activating a heating element of the vehicle, the heating element associated with a microbial reduction process, determining that a time period associated with the microbial reduction process has expired, deactivating, based on the expiration of the time period, the heating element of the vehicle, and presenting a second indication that the vehicle is available for use.

Abstract: An industrial furnace for heating products such as steel products includes a thermally insulated enclosure, a plurality of burners arranged in the enclosure for heating products passing from one end of the enclosure to the other, the burners being distributed over a plurality of temperature-regulated heating areas, and a recovery system designed for recovering heat energy from recovery fumes, The recovery system includes a rotary regenerator associated with each heating area, each of the rotary regenerators being configured to receive a predetermined flow rate of recovery fumes via a first duct, receive a predetermined flow rate of supply air via a second duct, preheat the supply air in order to supply the burners of the associated heating area with a predetermined flow rate of preheated combustion air via a third duct, and discharge exhaust fumes via a fourth duct.

Abstract: A single use syringe assembly includes a barrel having a chamber for retaining fluid, an open proximal end and a distal end including an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with the chamber. A needle cannula having a lumen therethrough is connected to the elongate tip so that the lumen is in fluid communication with the passageway. An elongate needle shield having a longitudinal opening therein is hingedly connected to the barrel. A needle shield is capable of pivoting from an open position or a closed needle protecting position. The plunger including an elongate body portion and a stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel. Structure is provided for locking the plunger in the barrel by applying distally directed force to the plunger after fluid has been delivered from the chamber.
