In one example a projection system having at least one main projector projects a first image onto a main projection area of a projection surface. The projection system may further include a relief projector that when activated projects a second image onto a backup projection area of the projection surface. The projection system may be provided with a sensor capable of sensing at least one characteristic of the at least one main projector, the main projection area, or the projection surface. The projection system may include a control system in communication with the sensor, wherein the control system activates the relief projector in response to the sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fail-safe projection system","description":"The technology described herein relates generally to a projection system having a fail-safe feature for use in a presentation or display.
