Abstract: A transparent layered element includes two outer layers that each have a smooth outer main surface and are constituted of dielectric materials having substantially the same refractive index. The layered element also includes a central layer inserted between the outer layers. The central layer is formed either by one or more layers made of metallic material or made of dielectric material having a refractive index different from that of the outer layers. All of the contact surfaces between two adjacent layers of the layered element are textured and parallel to one another. A ratio of a total reflection of the layered element on a side of a first outer layer in a given wavelength range to a total reflection of the layered element on a side of a second outer layer in the given wavelength range is greater than or equal to 1.5.

Abstract: A transparent layered element with diffuse reflection properties includes two outer layers made of dielectric materials having substantially the same refractive index and a central layer intercalated between the two outer layers, formed either from a single layer which is a dielectric layer with a refractive index different from that of the outer layers or a metallic layer, or from a stack of layers which includes at least one dielectric layer with a refractive index different from that of the outer layers or a metallic layer. The upper outer layer is a sol-gel layer including a silica-based organic/inorganic hybrid matrix.

Abstract: An actuator for controlling the operation of an apparatus comprises a panel (16) and an acoustic sensor (26). The panel provides a partition within a building structure, while the acoustic sensor is adapted to detect acoustic waves propagating through the panel. When a user exerts pressure against the panel, the sensor detects the acoustic waves that are formed and emits signals for controlling the operation of an apparatus, such as a doorbell, a light source, a television, a sound system, a ventilation system, a window blind, a radio or an alarm.
