Patent number: 11962118Abstract: A multilayer mirror comprises a reflector section including a plurality of alternating layers of a high index material and a low index material, and a filter section over the reflector section. The filter section comprises a first filter layer including a low index material on a layer of high index material of the reflector section; a second filter layer on the first filter layer, the second filter layer comprising a high index material that is different than the high index material in the reflector section; and a third filter layer on the second filter layer, the third filter layer comprising a low index material. Each filter layer has an optical thickness greater than or equal to the optical thickness of each layer of the alternating layers. The filter section substantially blocks ultraviolet (UV) energy, thereby preventing UV energy from substantially impinging on the high index material of the reflector section.Type: GrantFiled: October 27, 2020Date of Patent: April 16, 2024Assignee: Honeywell International Inc.Inventors: Randy Ramberg, Lance Vrieze, Steven C.

Patent number: 11255672Abstract: A system that includes a high performance sensor to provide accurate measurements and at least one dissimilar sensor that is less accurate. The at least one dissimilar sensor is of a different type of sensor than the high performance sensor while providing a same type of measurement as the high performance sensor. The at least one dissimilar sensor has a longer life expectancy than the high performance sensor. An at least one controller is configured to start both the high performance sensor and the at least one dissimilar sensor at startup of the system, to turn off the high performance sensor after a select period of time, and to output measurement data based on measurements of the high performance sensor while the high performance sensor is on and output the measurement data based on the at least one dissimilar sensor when the high performance sensor is off.Type: GrantFiled: October 28, 2019Date of Patent: February 22, 2022Assignee: Honeywell International Inc.Inventors: Alan Bruce Touchberry, Dean Eivind Johnson
