Abstract: Active matrix liquid crystal displays, mainly applicable to screens with small dimensions, fabricated for example starting from silicon substrates, are especially applicable to display operation in color sequential mode. The pixel comprises a pixel electrode controlled by a control transistor and counter-electrodes situated on the same side of the liquid crystal as the pixel electrode and parallel to the pixel electrode; the liquid crystal is composed of molecules having a natural rest orientation in the absence of a voltage between the pixel electrode and the counter-electrodes and a different orientation in the presence of an electric field created between the pixel electrode and the counter-electrodes. Erase electrodes are situated on either side of the pixel in a transverse direction with respect to the counter-electrodes and are designed to produce, during an erase phase, an erase electric field tending to return the molecules of the liquid crystal to their rest orientation.

Abstract: A photochromic structure includes a plastic support of optical grade with good light transparency, having at least one face with an adhesive layer impregnated with a solution of a solvent with photochromes, having a flexible host matrix for the photochromes, which is mounted by adhesion onto another support. A structure with a uniform flexible photochromic matrix, which has rapid transition times, notably a rapid relaxation time, is thus obtained. The structure is mountable, and advantageously repositionable. It is produced via a process using roll-milling combined with a system for dispensing the solvated solution of photochromes upstream of the rolls, via which a support strip of an adhesive is entrained by the rolls, and the adhesive is gradually impregnated and then laminated on another support.

Abstract: The disclosure concerns electron tubes. A tube such as a cathode-ray tube consists of several parts, namely the stem, the neck, the cone and the screen of the front face. To build a tube such as this more compactly while, at the same time, improving the quality of the fabrication, a new construction of the neck is proposed. In the prior art, the neck is a glass tube to which there is soldered a glass stem through which pass the connection terminals towards the various electrodes, internal to the tube. Here, the neck is built in the form of a stack of alternating metallic rings and ceramic rings. The metallic rings are used for the supporting of and electrical connection to the internal electrodes. The ceramic rings are used to insulate the metallic rings. The brazings between metallic rings and ceramic rings provide for vacuum tightness. The base of the tube is a ceramic washer without drillings other than lateral ones for the connections to pass through. The connections are made chiefly around the neck on the metallic rings.

Abstract: A wavefront analyzer comprises a network of adjustable converging microlenses dividing an incident wavefront into multiple beams and creating a respective focal point for each beam, and a network of light-sensitive detectors placed behind to detect positions of these focal points. The microlenses network is formed from a liquid crystal layer operating in transmission with an array of electrodes forming liquid crystal pixels whose refractive index is controllable by a voltage applied individually to each electrode. Each converging microlens comprises a subset of pixels grouped in a region constituting the microlens, the pixels of a subset having indices that vary radially in a monotonic manner by distance from a central point of the region to its edges, enabling the microlens to operate in refractive mode. The number, position, size and focal length of the microlenses can be adjusted by the profile of the voltages applied to the array of pixels.
