The rotary assembly additionally is designed to permit progressive transition of the lighting between the first and second distinctive lighting positions.

Abstract: Method, device and system for generating a light control parameter for controlling light (20), e.g. ambient light, in response to an audio signal (A). The audio signal (A) is analyzed in order to extract a temporal evolution of semantic content of the audio signal (A). A light control parameter is then generated according to the temporal evolution of semantic content of the audio signal (A), either on-line or off-line. This enables generating light that is perceptually aligned with the audio signal, e.g. music. In a preferred embodiment spatial properties of the audio signal (A) are extracted, and separate light control parameters are generated for controlling light sources spatially positioned according to the spatial properties of the audio signal, e.g. for stereo or surround sound systems where light sources are positioned near each loudspeaker. Such embodiment enables spatial correspondence between light and audio.

Abstract: Currently, various television standards use different aspect ratios. For example, a wide screen aspect ratio of 16:9 is gaining popularity over the existing TV broadcasts that use 4:3 aspect ratio. A method of scaling an image horizontally with a uniform or non-uniform scaling ratio is referred to as “panoramic scaling”. A device 100 and method 800 of scaling an image 102 by means of a scaling function 121 that is generated on the basis of a motion vector 101 of at least a part of the image 102 is disclosed. The device 100 can be used in an image processing apparatus or in an image display apparatus for converting a first image with a first aspect ratio to a second image of a second aspect ratio. The disclosed device 100 is useful in reducing the visual distortion introduced by the panoramic scaling especially in case of moving objects in a scene.

Abstract: A system and method for obtaining a sight screening as well as previous and current optical prescriptions (specifications) for purchase of glasses and contact lenses operated by one's self, through a voice-activated response self-refraction, or a technician/optician assisted refraction, at a convenient location or possibly several different customer diagnostic, electronic store locations where digital instruments interface and may transfer either directly back to the customer, or to a remote, interactive audio-video diagnosing and assisting, consulting eye doctor (ophthalmologist or optometrist) who interprets the digital data, diagnoses, consults, delivers health care, and authorizes the specifications, whereby the store technician/optician gathers data for purchase and electronically sends the data to a lens lab for fabrication and delivery of glasses or contact lenses to the store or directly to the customer.

Abstract: A vehicle headlight comprising at least one lighting module mounted on a support. The module comprises a base with a mounting surface inclined backward and toward the top of the headlight. The support comprises a corresponding mounting surface. Positioning means with sliders are provided on these surfaces so as to be able to extract the module and fit it by a translational movement in a direction contained within the plane of the mounting surfaces. The housing comprises a removable portion positioned in the extension of the module in the direction of translation of the positioning means with sliders. The wall of the housing comprises precuts on the circumference of the removable portion. This arrangement makes is possible to easily replace a bulky lighting module such as that of a headlight with style functions.

Abstract: A lighting and/or signaling device and method comprising an opaque element that can move between at least two positions, one of the positions interposing the opaque element between the main light source and the optical focusing device, in which the opaque element is arranged so that when it is interposed between the main light source and the optical focusing device it prevents rays originating from outside the lighting and/or signaling device from being focused, especially in a line or spot, by the optical focusing device, in order to prevent degradation of the lighting and/or signaling device.

Abstract: A display apparatus includes a plurality of electrofluidic chromatophore (EFC) pixel cells. Each pixel cell includes a fluid holder for holding a polar fluid and a non-polar fluid having differing display properties, the fluid holder including a reservoir having an orifice with a small visible area projected in the direction of a viewer onto the polar fluid, and a channel with a geometry having a large visible area projected in the direction of a viewer onto the polar fluid. The channel is connected to the reservoir via said orifice so as to enable free movement of the polar fluid and non-polar fluid between the channel and the reservoir. The reservoir is formed in a laminated resin structure of homogenous resin film layers, including an orifice film layer and a reservoir film layer.

Abstract: The invention is directed to a method for making a spectacle lens for a non-presbyopic person wherein the spectacle lens is a ready-to-wear lens and has at least one zone having an optical effect to reduce vision stress. In the method, at least one of the following is provided: the contour of the ready-to-wear spectacle lens and one or several visual points whereat the person looks through the ready-to-wear spectacle lens for one or several visual tasks in the near range. This method step is followed by setting at least one of: a design reference point of the zone, the extent of the zone, the optical effect within the zone based on the provided contour, and the visual points. The spectacle lens is then made with this zone.
