Abstract: A system and method for sterilizing one or more high-touch implements, such as shopping carts, using ultraviolet (UV) light within a contained chamber for a specified period of time. In an embodiment, one or more shopping carts may be guided into a sterilization chamber through a front-side opening of an apparatus. Once the shopping cart is in place inside the sterilization chamber, a UV light process may be engaged whereby several UV lights will be turned on to flood the sterilization chamber with UV light. UV light has been shown to be effective at killing bacteria, viruses, mold, and other pathogens with exposure in as little as 5 seconds. The sterilization procedures results in sterilizing a shopping cart for next use as sterilized carts may be collected in a corral designated form newly sterilized shopping intended for next use.

Abstract: Disclosed herein is a system and a method for controlling laser energy deposition in order to normalize post-sintering temperatures is presented. Sensors provide feedback for in-situ control of laser power to reduce the influence the pre-sintering thermal profile has on the post-sintering temperatures. By actively controlling the laser during its scanning, the post-sintering temperatures can be more accurately controlled, resulting in mechanical and geometric improvements in part quality.
