Abstract: A highly efficient channel drop filter. The filter employs a coupling element including a resonator-system between two waveguides, which contains at least two resonant modes. The resonator-system includes one or more interacting resonant cavities which in addition to being coupled to the waveguides, can also be coupled directly among themselves and indirectly among themselves via the waveguides. Each component of the coupling element can be configured or adjusted individually.  The geometry and/or dielectric constant/refractive index of the resonator-system are configured so that the frequencies and decay rates of the resonant modes are made to be substantially the same. The filter can achieve 100 % signal transfer between the waveguides at certain frequencies, while completely prohibiting signal transfer at other frequencies. In exemplary embodiments, the filter is configured with photonic crystals. In accordance with alternative embodiments of the invention, the filter is configured as an absorption induced on/off switch and modulator. The switching action is achieved with either electrical or optical absorption.

Abstract: A pedicle screw assembly includes a fastener 30 including a tip end 32 for insertion into bone 90 and an expandable head 34 at the opposite end of the fastener. The expandable head 34 has an outer surface 44 including a convex portion, a recess 46 having an inner surface 48 and defining an inner dimension, and at least one slot 50 extending between the inner and outer surfaces thereof for allowing expansion of the head. The assembly also has an insert 56 which can be positioned at least partially in the recess 46, the insert 56 having an outer surface 62 and defining an outer dimension that is greater than the inner dimension of the recess 46. The assembly includes a coupling element 70 including a rod receiving opening 94, a bore 80 for receiving the head of the fastener 30, and a seat 88 for receiving the head 34 of the fastener, the seat 88 including a concave portion for receiving the convex portion of the head and allowing the fastener 30 to pivot relative to the coupling element 70 before being locked therein. After an orthopedic rod 92 has been positioned within the coupling element 70, a locking element 96 associated with the coupling element locks the orthopedic rod 92 in the rod-receiving opening 94. The locking element 96 is adapted to be forced against an orthopedic rod arranged in the rod receiving opening 94, to in turn force the insert 56 into the recess of the expandable head 34 so that the outer dimension 62 of the insert 56 bears against the inner dimension 48 of the head 34, thereby expanding the outer surface 44 of the head against the seat 88 of the coupling element 70 for locking the fastener 30 from further pivotal movement relative to the coupling element 70. In other preferred embodiments, the head is expandable by virtue of the material of which it is made such as carbon fiber.

Abstract: Un solvant modifié miscible avec l'eau utilisé pour extraire l'acide acétique des courants aqueux est constitué d'un mélange pratiquement pure d'isomères di-alkyle amines très ramifiés. Ce solvant est pratiquement exempt de mono-alkyle amines et d'alcool. Les mélanges de solvants contenant un tel solvant modifié en plus d'un solvant souhaité, de préférence un hydrocarbure à point d'ébullition bas qui forme un azéotrope avec l'eau, sont utilisés dans l'extraction de l'acide acétique des courants gazeux aqueux. Par ailleurs, un processus de fermentation microbienne anaérobie utilisé pour produire de l'acide acétique, emploie de tels solvants dans des conditions qui limitent la formation d'amide par le solvant, et augmente ainsi l'efficacité de l'opération de récupération d'acide acétique. En outre, les procédés d'extraction directe d'acide acétique et de fermentation extractive d'acide acétique utilisent également ces solvant modifiés et augmentent l'efficacité de production d'acide acétique. Cette efficacité accrue est possible lorsque la source d'énergie utilisée pour la fermentation microbienne contient du gaz carbonique, ce procédé comprenant une étape d'extraction de gaz carbonique précédant l'extraction de l'acide acétique dans le solvant.

Abstract: A method of generating a mask for use in an ion beam sputtering system for coating oxides on a plurality of mirrors located on a rotating platen. The mask reduces non-uniformity of the oxide coating the mirrors in a radial direction from the platen axis of rotation. The shape of the mask is derived from a test run of the coating thickness on a stationary glass plate having the same area as the platen. The resulting coating thickness on the glass plate is measured by an ellipsometer as a function of position. The measured coating thickness is mapped to produce a corresponding flux pattern. A coating rate map is then determined by dividing coating thickness by coating time. The functional form of the mask is determined in width along a radial distance of the platen. The coating rate for a predetermined radial distance is obtained by adjusting angular width of the mask, which blocks a portion of the flux radially and angularly, until the desired average coating rate is obtained for that radial distance. After all the radial distances or bands have been assigned their desired angular widths, the function form of the mask is determined.
