SYSTEM, APPARATUS AND METHOD FOR USING BIREFRINGENT LENSES TO CREATE HOLOGRAMS FROM RECEIVED ELECTROMAGNETIC RADIATION

Thu, 23 Feb 2017 08:00:00 EST

The inventors have discovered a method to improve image quality in holography and, for the first time, utilize lenses made from birefringent materials to advantageously split an incoming beam of either coherent or incoherent light into two coincident beams with different focal lengths that interfere with one another and thus create holograms free of electro-optical or pixelated devices.

The invention provides a privacy window system (1) comprising a window panel (100), a lighting unit (200), and a control unit (300), wherein (i) the window panel (100) comprises a first surface (110), a second surface (120) and an edge (130), wherein the window panel (100) is transmissive for visible light wherein at least one of the surfaces (110,120) of the window panel (100) comprises surface structures (105), configured to generate visible privacy light (101) under irradiation with lighting unit radiation (201); (ii) instead of using edge-lighting for the irradiation of the window panel (100), the lighting unit (200) is configured to irradiate one of the surfaces (110,120) of the window panel (100) with said lighting unit radiation (201) thereby inducing said privacy light (101) and reducing visibility through the window panel (100) in at least one direction; and (iii) the control unit (300) is configured to control the lighting unit radiation (201) as function of an input signal.



OPTICAL FILM AND DISPLAY DEVICE COMPRISING THE SAME

Thu, 23 Feb 2017 08:00:00 EST

An optical film includes a base film including a base and first and second lens pattern portions, where the first lens pattern portion includes a first surface, a first side surface, which extends from one side of the first surface to a surface of the base and a second side surface, which extends from the other side of the first surface and the surface of the base, the second lens pattern portion includes a second surface, a third side surface, which extends from one side of the second surface to the surface of the base, and a fourth side surface, which extends from the other side of the second surface and the surface of the base, and an angle between an imaginary line and the surface of the base is less than about 50 degrees.



ARTICLE HAVING OPTIMISED THERMOMECHANICAL PROPERTIES, COMPRISING A LAYER OF TITANO-ORGANIC NATURE

Thu, 23 Feb 2017 08:00:00 EST

The invention relates to an article comprising a substrate having at least one major surface coated with a layer A of a material obtained by ion beam assisted vacuum deposition of at least one titanium oxide and of at least one organosilicate compound B, said material having a refractive index at 550 nm higher than or equal to 1.8, an extinction coefficient k at 550 nm lower than or equal to 0.02, and an H:E ratio higher than or equal to 0.046, where H and E designate the hardness of the material and the elastic coefficient of the material, respectively.



ANGULAR MOTOR SHAFT WITH ROTATIONAL ATTENUATION

Thu, 16 Feb 2017 08:00:00 EST

A linear actuator assembly has a linear actuator including a motor shaft extending from a base with a piezoelectric component oscillate the shaft. The shaft has a faceted surface. A movable carriage has a notch with at least one flat surface that receives the shaft of the linear actuator. The carriage is in direct and continuous contact with the motor shaft at the notch such that the motor shaft's facet is in contact with the flat surface of the notch, when the carriage moves linearly along a travel axis. A spring is coupled to the carriage to urge the motor shaft into contact with the notch of the carriage so as to maintain contact between the motor shaft facet and the flat surface of the notch to inhibit rotation of the motor shaft.
