Publication number: 20230251406Abstract: Dynamic mirror assemblies are disclosed that can vary the amount of light reflected, that include a mirror and a switching material. The switching material is placed between the mirror and a viewer, and has a dark state and a light state, and switches state in at least one direction due to a photochromic reaction, and switches in the other direction due to one or more of a photochromic reaction or an electrochromic reaction or a thermal reversion above a threshold temperature.Type: ApplicationFiled: July 13, 2021Publication date: August 10, 2023Applicant: SOLUTIA CANADA INC.Inventors: JONATHAN ROSS SARGENT, RYAN J. GIBSON, JEREMY GRAHAM FINDEN, NEIL ROBIN BRANDA, GREG STUART, JAMES DANIEL SENIOR, MATTHEW NEAL ROBERTS

Publication number: 20220206199Abstract: A system of networked controllers includes one or more switchable optical filters, and the switchable optical filters are photochromic and electrochromic. The system also includes a master controller, and one or more slave controllers operably connected to the one or more switchable optical filters. At least one of the one or more slave controllers is communicatively coupled to the master controller. The master controller is configured to transmit a switching command to the at least one of the one or more slave controllers. Each slave controller is operable, in response to receiving the switching command, to cause a corresponding switchable optical filter to transition from a first state to a second state.Type: ApplicationFiled: March 16, 2022Publication date: June 30, 2022Applicant: SOLUTIA CANADA INC.Inventor: MATTHEW P. SMIT
