Abstract: An apparatus is disclosed that includes a switchable optical filter having a layer of switchable material; a light source providing light of a wavelength that causes the switchable material to transition from a faded state to a dark state, or a dark state to a faded state; and a switch for controlling activation of the light source.

Abstract: 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.

Abstract: A packaged film assembly includes a packaging material and a switchable film. The switchable film is packaged in and attached to at least a portion of the packaging material.

Abstract: Layered assemblies are disclosed, that include a variable transmittance layer having opposing first and second sides; at least a first reflectance color-balancing layer positioned on the first side of the variable transmittance layer; and a transmittance color-balancing layer positioned on the first side or the second side of the variable transmittance layer. The variable transmittance layer may be variable between a dark state and a light state, and may have a dark state transmittance spectrum when in the dark state and a different light state transmittance spectrum when in the light state.

Abstract: The disclosure provides, in part a seal system for sealing a film. The disclosure further provides, in part, a sealed film comprising a first and a second substrate; a first and a second electrode disposed on the surface of at least one of the substrates; a switching material disposed between the first and second substrates; a first seal and a second seal; the first seal disposed along an edge of the switching material, separating the switching material from the second seal.

Abstract: An apparatus comprising a switchable optical filter comprising a layer of switchable material, the switchable material comprising a photochromic/thermochromic, a photochromic/photochromic, or a photochromic/electrochromic compound; a first light source providing light of a wavelength that causes the switchable material to transition from a faded state to a dark state, or a dark state to a faded state; and a switch for controlling activation of the first light source

Abstract: 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.

Abstract: A compound according to Formula IA and IB, reversibly convertible under photochromic and electrochromic conditions between a ring-open isomer A and a ring-closed isomer B is provided. For substitutent groups, Z is N, O or S; each R1 is independently selected from the group consisting of H, or halo; each R2 is independently selected from the group consisting of H, halo, a polymer backbone, alkyl or aryl; or, when both R2 together form —CH?CH— and form part of a polymer backbone; each R3 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl; each R4 is aryl; and each R5 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl.
