    摘要: This invention relates to a remotely optically powered fiber optic switch, e.g. in a fiber optic network, and a GRIN-rod (Graded-Refractive-Index-rod) lens with integrated planar mirror as a switching element, in particular suited for fiber optic switches. A distribution panel, in which the switching element, a wavelength-division demultiplexer, a light-into-current converter, and an actuator for the switching element are situated, is remotely optically powered from a station in the network. Part of this station is a laser diode which feeds a powering lightwave via a wavelength-division multiplexer into an optical fiber interconnecting the station with the distribution panel, which fiber can also be used for data transmission. The light-into-current converter receives the powering lightwave and generates an electric current for driving the actuator and moving the switching element. A GRIN-rod lens with integrated planar mirror serves as switching element by rotating it in a ferrule and establishing different light paths depending on the position of the integrated mirror with respect to lightwaves optically coupled to the end facets of the GRIN-rod.

    摘要: The invention relates to the field of chemistry and more specifically to the field of medicinal chemistry. The invention is directed to N-acyl-dipeptide-like compounds having the general formula I wherein substituents A, B, X, Y, R1, R2, and subscripts n, m, p and q have the same meanings as those given in the claims. The invention is equally directed to pharmaceutical compositions containing as an active ingredient at least one compound of general formula I either in acid or salt form with an organic or mineral base. The compounds persuant to the invention display interesting pharmacological properties which make them useful as drugs.
