Abstract:
A folded circularly symmetric illumination optic comprising a first light transfer mode having a first central refractive surface and a second central refractive surface, wherein one of the first and second central refractive surfaces has at least one peened feature; a second light transfer mode having a first refractive surface, a first TIR surface, a second TIR surface and a second refractive surface; a third light transfer mode having a first refractive surface, a first TIR surface and a second refractive surface, wherein the first TIR surface has at least one peening feature, and wherein the second refractive surface is conical; wherein the first TIR surface and second refractive surface of the second light transfer mode is coincident at least one point, wherein the second refractive surface of the third light transfer mode is coincident with the first TIR surface and second refractive surface of the second light transfer mode.
Abstract:
A light funnel collimator has a central lens surface and a back reflecting surface, shaped to provide a wider background beam and a narrower hotspot beam within but off- center of the wider beam. One of the beams is on-axis of the collimator, and the other beam is off-axis. The reflector is at least partly asymmetrical relative to the axis, and provides or contributes to the off-axis beam.
Abstract:
The present invention relates to a power and/or telecommunication cable (Ia, Ib) including one or several conductor elements (10,20,30) surrounded by an outer sheath, wherein said outer sheath (40,50) comprising a first layer (40a, 40b) able to emit light radiation, and a second layer (50) made of a light transmitting thermoplastic polyurethane (TPU) material surrounding the first layer (40a, 40b), so that the first layer (40a, 40b) is visible through the second layer (50).
Abstract:
BET PET is an entertainment device for at least two players. The operation of said device is very simple. It consists of a mechanism that enables a choice to be made between 4 possible numbers (0, 1, 2 and 3). Each player chooses one of these 4 options and makes a prognosis on the possible total of the choices of each player. The player with the correct prognosis wins. If there are no correct prognoses, the game is played again. The model is based on a hand-held device that can be used to play the game, with digital versions for mobile telephone and Internet platforms suitable for the future development of the game and growth of the ludic activity.

Abstract:
One embodiment of a method of calculating an optical surface comprises calculating a meridional optical line of the surface. A ray is selected that passes a known point defining an end of a part of the optical line already calculated. The optical line is extrapolated from the known point to meet the ray using a polynomial with at least one degree of freedom. The polynomial is adjusted as necessary so that the selected ray is deflected at the extrapolated optical line to a desired target point. The polynomial is added to the optical line up to the point where the selected ray is deflected. The point where the selected ray is deflected is used as the known point in a repetition of those steps.
Abstract:
An optical device (270) for coupling the luminous output of a light-emitting diode (LED, 22) to a predominantly spherical pattern comprises a transfer section (271) that receives light from the transfer section and spread the light generally spherically. A base of the transfer section is optically aligned and/or coupled to the LED so that the LED's (22, 23, 24) light enters the transfer section. The transfer section (271) can comprises a compound eelliptical concentrator (271) operating via total internal reflection. The ejector section can have a variety of shapes (272, 273), and can have diffusive features on its surface as well.
Abstract:
An internet payment system including a participating merchant server (24) supporting web pages on which product or service offerings are displayed in response to queries from a user device (10) using a connections apparatus and a browser. The merchant server interacting with the user device browser permits a user to select at least one offering and to indicate a method of payment, at least one method of payment being a transfer link. The Internet system also comprises a participating financial institution server (44) maintained by a financial institution at which the user has a financial account. The server permits the user to gain direct access to his financial account. In addition, the Internet payment system includes a main transportation server to which both the user device and merchant server are connected in response to the user selecting the transfer link as the method of payment. The merchant server transmits information to the transport server provides a selection of financial institutions from which the user can select an institute at which he has an account for payment for the offering. The main transport server transmits user inputs directly to the financial institution server to authorize payment to the merchant for the offering without storing the inputs.
Abstract:
A composition includes a first chelating agent, a second chelating agent, and a plurality of metal ions. In one embodiment, the second chelating agent includes citric acid and is different than the first chelating agent. A method for forming a composition includes mixing a first chelating agent, a second chelating agent, and a metal salt together to form a mixture and processing the mixture to form at least one of a granulated composition and a powdered composition. In some embodiments, the second chelating agent includes citric acid and is different than the first chelating agent.
