A switchable device for changing the opacity of at least a portion of a glazing is described. The switchable device comprises at least two (a first and a second) switchable regions in electrical communication with at least two (a first and a second) electrical connector regions. Each switchable region comprises an electrically actuated variable opacity layer between a first electrode and a second electrode, the first switchable region being arranged relative to the second switchable region such that upon connecting the first and second electrical connector regions to a suitable power supply, the opacity of the first and second switchable region changes such that at least two (a first and a second) portions of the switchable device have a change of opacity, the first portion of the switchable device having a different opacity to the second portion of the switchable device.

In an aspect of the present invention, a gasochromic dimming mechanism is provided which includes a gasochromic dimming component provided with a pair of transparent substrates, the transparent substrates being arranged to face each other, and a dimming part formed on one or both facing surfaces of the pair of the transparent substrates, wherein an optical property of the dimming part is reversibly changed by hydrogenation and dehydrogenation; and a hydrogen-air mixture gas supply unit that supplies a hydrogen-air mixture gas between the pair of the transparent substrates. The hydrogen-air mixture gas supply unit includes an electrolysis cell including a mixer for mixing hydrogen and air, a polymer electrolyte membrane, a porous electrode formed in the polymer electrolyte membrane as an anode, and an air supply unit that supplies the air to the mixer, the porous electrode being arranged on a flow channel of the air.

A display device includes a display panel including a first area and a second area surrounding the first area, a plurality of pressure sensors disposed on the display panel, a dielectric layer disposed on the plurality of pressure sensors, and a bracket accommodating the display panel, the plurality of pressure sensors, and the dielectric layer. The dielectric layer forms a capacitance between the plurality of pressure sensors and the bracket. A first capacitance corresponding to the first area is smaller than a second capacitance corresponding to the second area.

A method for displaying virtual content to a user, the method includes determining an accommodation of the user's eyes. The method also includes delivering, through a first waveguide of a stack of waveguides, light rays having a first wavefront curvature based at least in part on the determined accommodation, wherein the first wavefront curvature corresponds to a focal distance of the determined accommodation. The method further includes delivering, through a second waveguide of the stack of waveguides, light rays having a second wavefront curvature, the second wavefront curvature associated with a predetermined margin of the focal distance of the determined accommodation.

An electrokinetic device is configured as a dynamic lens cover and/or filter for an imaging assembly, e.g., of a mobile device, to selectively allow electromagnetic radiation to pass through a lens of the imaging assembly when the dynamic lens cover is in a first operating state or to prevent electromagnetic radiation from reaching the lens of the imaging assembly when the dynamic lens cover is in a second operating state. The electrokinetic device includes transparent first and second substrates, and a compaction trench surrounding the lens of the imaging assembly. The compaction trench stores pigment when the dynamic lens cover is in the first operating state. In the second operating state pigment is dispersed within a carrier fluid between the first and second substrates.
