Title: Automatic inspection method for contactlessly measuring an offset of a central feature of an object
Inventor: CSIPKES ANDREI
IPC: G02B6/38
Filed: 1996-06-13
Granted: 2002-06-11
Abstract: An automatic inspection method contactlessly measures the offset of a feature ofan object from a theoretical ideal center of the object, and is particularly suited for measuring at an endface of an optical fiber termination the eccentricity of an optical fiber core relative to a theoretical ideal center of the termination. The core is extremely smaller (typically between about 50 and 500 times) in size than the termination boundary. An inspection system for implementing the novel inspection method has a feature imager, one or more boundary segment imagers but preferably four in number, and a machine vision system connected to the foregoing imagers. The feature imager is positioned to capture an image of the feature (e.g., fiber core endface), and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the object (e.g., termination endface). The machine vision system determines the offset, or eccentricity, based upon the feature image and the one or more boundary segment images.

Title: High efficiency polarization diversity receiver system
Inventor: HALL DAVID B
IPC: H04B10/61
Filed: 1996-11-21
Granted: 2003-08-12
Abstract: A polarization diversity receiver system for yielding multiple heterodyne optical output signals from an incident optical beam having a p-polarized component and an s-polarized component comprises first and second sequentially-arrayed polarizing beamsplitters, and three photodetectors, each of which receives a heterodyne optical signal. The polarization diversity receiver system tracks the largest of these three signals, and uses only this largest one for subsequent signal processing. There is a minimum for this largest signal that is dependent on the input polarizations of the two optical fields whose beat note is the heterodyne signal. Thus, the object is to maximize the minimum of this largest of the three heterodyne signals. The first polarizing beamsplitter ideally splits the incident beam into a transmitted beam portion including approximately 100% of the p-polarized component and approximately 33% of the s-polarized component, and a reflected beam portion including approximately 0% of the p-polarized component and approximately 67% of the s-polarized component. The reflected beam portion exits from the first polarizing beamsplitter as a first heterodyne optical output signal, and impinges on a first photodetector. The transmitted beam portion exits from the first beamsplitter, and then undergoes an effective 45O rotation of its polarization eigenstates around its axis of propagation, either prior to or during its passage through the second polarizing beamsplitter. The second beamsplitter splits the rotated transmitted beam portion into second and third heterodyne optical output signals, which respectively impinge upon second and third photodetectors.

IPC: H04B1/59
Filed: 1995-05-31
Granted: 2003-12-09
Abstract: A radio range finding system (10) includes a radio range finder (12) and a plurality of remote mobile transponders (14). The radio range finder (12) transmits a signal modulated with an address code identifying a particular mobile transponder. When a mobile transponder receives the modulated signal (Ms) transmitted by the radio range finder and the modulated signal has been modulated with an address code that corresponds to the address assigned to that mobile transponder, the mobile transponder transponds a return signal (Rs) to the radio range finder. A receiver (32) in the radio range finder conveys the received signal to a mixer (30) which also receives an internal carrier signal identical to the modulated signal output by transmitter (20). The output of the mixer is then filtered and demodulated to yield an output signal proportional to the distance between the mobile transponder (14) and the radio range finder (12).

Abstract: Le traitement, au moyen d'un processus d'adsorption à sec, d'un gaz émis au cours d'un processus électrolytique à chaud assurant la production d'aluminium s'effectue dans au moins deux étages (3, 4). De l'oxyde d'aluminium particulaire (l'adsorbant) passe par les étages (3, 4) du processus d'adsorption à contre-courant par rapport au gaz. De cette manière, le gaz est traité avec un adsorbant partiellement épuisé dans un premier étage d'adsorption à sec, après quoi l'adsorbant particulaire est séparé du gaz en aval du premier étage d'adsorption. Une partie de l'adsorbant particulaire séparé est éliminée (33) du processus d'adsorption dans le but de renvoyer les substances fluorées adsorbées vers le processus électrolytique. Le reste de l'adsorbant séparé est renvoyé vers le premier étage d'adsorption afin d'optimiser l'adsorption des substances fluorées et la désorption du dioxyde de soufre dans cet étage. Simultanément, le gaz est transféré vers un second étage d'adsorption à sec. Dans ce second étage, le gaz est traité avec de l'oxyde d'aluminium particulaire réactif, pratiquement non épuisé, de façon à ce que tout fluorure gazeux restant dans le gaz soit adsorbé très efficacement, alors qu'une partie considérable du dioxyde de soufre dans le gaz est simultanément adsorbée. Finalement, l'oxyde d'aluminium particulaire est séparé du gaz en aval du second étage d'adsorption à sec, avant que le gaz ne soit rejeté dans l'atmosphère environnante. L'oxyde d'aluminium séparé est transféré vers le premier étage d'adsorption, éventuellement après un passage par un étage de désorption (8) destiné à extraire le dioxyde de soufre adsorbé et donc à réduire les rejets de dioxyde de soufre provenant de la production d'aluminium. La séparation de dioxyde de soufre dans le second étage d'adsorption est améliorée par le recyclage, vers le second étage d'adsorption, de l'oxyde d'aluminium qui a subi le traitement de désorption.
