Title: Fiber optic transimpedance receiver.
Inventor: KRUSE HERMAN
IPC: H04B10/2507
Filed: 1990-12-03
Abstract: A transimpedance receiver for broad band optical signals, such as carry multichannel CATV signals or broad band data over an optical fiber which may vary in length (e.g. from 2 km to 20 km) such that the optical power at a photodetector of the receiver may vary widely depending upon where the receiver, and is installed in the fiber optic distribution system utilizes a broad band device, preferably a GASFET, the internal capacitance and gain of which enables amplification over the broad band frequency range without oscillation. Different values of transimpedance for converting the current signal from the photodetector into an output voltage at the output (the drain) of the device which is in a range within which the device is linear, and does not introduce distortion into the signal, is obtained by connecting, between the output and the input of the device, a feedback resistor selected from a group consisting of resistors of different value each dependent upon the optical power of the optical signal applied to the photodetector. The output voltage is coupled to an electrical transmission line which may be a low impedance coaxial line using a buffer amplifier incorporating a device of the same type as used in the transimpedance amplifier which has connected thereto networks for controlling the spectral response of the receiver so that it remains essentially flat over the broad band frequency range.

Abstract: Selon un procédé d'une installation centrale de verrouillage à télécommande pour véhicules à moteur, on utilise un émetteur capable de transmettre des signaux codés - par exemple, des signaux acoustiques aux ultra-sons, optiques aux IR et/ou des ondes de haute fréquence OUC - à un récepteur agencé dans ou sur le véhicule. Lorsque l'installation de verrouillage centralisé est actionnée pour la première fois, elle est initialisée ou réinitialisée avant son actionnement suivant afin d'annuler le code antérieur. Le code utilisable à l'avenir, ou le nouveau code utilisable à l'avenir lors d'un changement du code, est déterminé pour la première fois ou modifié en mettant le récepteur dans un état dans lequel il peut être (ré)initialisé, par exemple au moyen d'un code spécial de commande. Lors de sa (ré)initialisation, le récepteur actionne un affichage déjà disponible du véhicule à moteur, afin d'indiquer que le récepteur est dans un état où il peut être ré(initialisé).

Abstract: This invention relates to methods for producing transgenic plants that contain a gene of interest and that are free of foreign ancillary nucleic acids. These methods allow for the production of plants which thus contain a desired gene, but which are free of vector sequences and/or marker sequences used to transform the plant. The method of transforming such plants calls for transforming the plants with a gene of interest by introduction of the gene on a DNA construct comprising a transposon and foreign ancillary nucleic acids; crossing the transformed plant through self-crossing or with another plant to obtain F1 or more removed generation progeny; and utilizing a means for selecting those progeny that carry the gene of interest and are free of the ancillary nucleic acids. Such progeny may be detected biochemically, by Southern hybridization, through the use of polymerase chain reaction procedures and other methods available in the art.
