Abstract: Disclosed are systems and methods of authenticating a user on a network, including, based on identity information received from the user, accessing at least one data source to retrieve data associated with the user, comparing the retrieved data against a listing of possible questions associated with the retrieved data to determine associations between the retrieved data and the listing of possible questions, based on a ranking of the listing of possible questions, formulating at least one question set using questions within the listing of possible questions for which retrieved data is available, where each of the at least one question set includes at least two different questions, causing at least some of the questions from the at least one question set to be presented to the user, and, based on responses to the questions from the user, determining whether the user is authenticated.

Abstract: A connector for connecting a wire to a balustrade rail, the connector comprising: a tubular body for receipt therein of a wire end portion and for positioning in the rail through a rail aperture; an opening in the tubular body for the wire to extend from the connector when the wire end portion is located in the tubular body; and a deflector for deflecting the wire at an angle to the wire end portion which is held in the tubular body, when the wire is under tension.

Abstract: This invention concerns an ellipsometer for the examination of a sample whereby the ellipsometer has a broadband light source on the emitter side and a detector on the receiver side for a receiver light beam reflected from the sample. A refractive optic for the generation of a measuring spot on the sample and an aperture arranged on the emitter side for the definition of a measuring spot on the sample. The spectroscopic ellipsometer of the present invention makes it possible to easily produce a precisely defined measuring spot on the sample.

Abstract: This invention concerns an ellipsometer for the examination of a sample (50) whereby the ellipsometer has a broadband light source (1) on the emitter side (A) and a detector (8) on the receiver side (B) for a receiver light beam reflected (3B) from the sample (50). A refractive optic for the generation of a measuring spot on the sample and a first aperture (2) arranged on the emitter side (A) for the definition of a measuring spot on the sample. [sic] Using the spectroscopic ellipsometer makes it possible to easily produce a precisely defined measuring spot on the sample (50).
