  • REGISTRATION AND OVERLAY ERROR CORRECTION OF ELECTROPHOTOGRAPHICALLY FORMED ELEMENTS IN AN ADDITIVE MANUFACTURING SYSTEM
    Publication number: 20160339646
    Abstract: In a method for printing a three-dimensional (3D) parts with an additive manufacturing system, a developed layer of an electrically charged powder material is produced on a transfer medium using an electrophotographic (EP) engine. The transfer medium and the developed layer are fed in a feed direction. A position of the developed layer on the transfer medium is detected using a first sensor having a first output that indicates the position. A position of a moveable build platform is adjusted relative to the transfer medium to reduce one or more overlay errors between the developed layer and an intermediate build surface of a three-dimensional structure retained on the moveable build platform based on the first output. The developed layer is transferred to the intermediate build surface using a pressing element.

  • System and Method for Generating Protective Obscuring Haze
    Publication number: 20160012697
    Abstract: A system and method of providing a protective cover to occupants of a room, which includes detecting an occurrence of a threatening event with a protection system deployed in the room, such as detecting gunfire with the protection system and/or receiving a transmitted command of the threatening event by the protection system, and emitting an obscuring haze into the room from a haze generator of the protection system in response to the detected occurrence of the gunfire. The emitted obscuring haze obscures the light of sight contact between a shooter and the occupants in the room, which provides a measure of cover for the occupants while other assistance is being organized. This reduces the chances that the shooter will be able to accurately shoot any victim, increasing the odds of victim survival.
