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.

Packaged film assembly for lamination between substrates

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.

Seal and seal system for a layered device

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.

A simplified switchable object and methods of making same are provided. The methods may include steps of applying a switchable material on a first surface of a first substrate, the switchable material having a thickness and a shape; applying a barrier material on the first substrate, circumferential to the switchable material; and applying a second substrate over top of, and in contact with, the switchable material and the barrier material, the first substrate, second substrate and barrier material defining a closed chamber encapsulating the switchable material. The methods may further include a step of applying a seal material.

Switchable objects and methods of manufacture

An eyewear control system for a variable transmittance optical filter assembly configurable to cover at least a portion of a lens of an eyewear device. The eyewear control system includes a controller communicatively coupled to a pair of load terminals. The eyewear control system also includes a light sensor communicatively coupled to the controller to provide a detector output signal, the light sensor being positioned to receive sunlight transmitted through the optical filter assembly and towards an eye of a person wearing the eyewear device, the detector output signal being set in dependence on an amount of sunlight received by the light sensor. The eyewear control system also includes a memory communicatively coupled to the controller and having encoded thereon computer program code executable by the controller to transition the optical filter assembly between operating states when coupled to the pair of load terminals. The controller is operable to vary a voltage across the load terminals in dependence on the detector output signal to vary an amount of sunlight transmitted to the eye by the optical filter assembly.
