US 11,113,933 B1 · Visual indication system for feedback controller

Abstract

A device for communicating a system status visually is disclosed. The device comprises a primary indicator and a secondary indicator, and in an embodiment comprises a surround indicator and a tail indicator. Both indicators allow light to pass through a translucent portion to be visible by a user, and the device utilizes illumination elements such as multicolor LEDs to present the indicators in colors to communicate system status or a data category to inform a user about the system with simplified color signals easily perceived at a distance. The device can be configured to accept multiple sensor or signal inputs and control one or more powered devices to effect feedback control of a system variable, e.g. temperature. The tail indicator can change colors to communicate a data category provided by a signal input. The surround indicator can change colors to communicate a system status.
