Title: Circuit arrangement for generating a control signal in dependence upon the occurrence of an extreme value of a sinusoidal oscillation and use ofsuch a circuit arrangement
Inventor: KAISER ULRICH
IPC: G01S13/02
Filed: 1990-03-21
Granted: 1997-12-16
Abstract: A circuit arrangement is described with the aid of which a control signal can be generated in dependence upon the occurrence of an extreme value of a sinusoidal oscillation. The circuit arrangement (10) includes a storage member (22) which is adapted to be charged via a diode (20) to one of the extreme values of the sinusoidal oscillation.  A discharge path (26) for the storage member (22) is present, the time constant of which is so dimensioned that within the period duration of the sinusoidal oscillation an appreciable discharge of the storage member (22) takes place, A switch element (24) controllable by the charge voltage of the storage member (22) furnishes the control signal at its output (14) for the period of time during which the charge voltage at the storage member (22) is smaller than the extreme value of the sinusoidal oscillation.  The circuit arrangement can be used in maintaining the oscillations of  a  resonance circuit stimulated to oscillate by means of a momentary HF carrier wave pulse.

Abstract: SPEECH CODING APPARATUS           ABSTRACT OF THE DISCLOSURE        A speech coding apparatus which selects an optimum code from a code book, the optimum code giving the minimum magnitude error signal between the input signal and the reproduced signal obtained by a filter calculation using a linear prediction parameter from a linear predictive analysis unit with respect to the codes of the code data, wherein use is made, as the codes, of a code formed by thinning to 1/M (M being an integer of two or more) the plurality of sampling values constituting the codes.  To compensate for the deterioration of the quality of the reproduced signal caused by thinning the sampling values in this way, an additional linear predictive analysis unit is further introduced and use made of an amended linear prediction parameter instead of the linear prediction parameter.

Abstract: A pressure vessel (10) has partially telescoped upper and lower shells (12, 14), a diaphragm (20a) with a peripheral edge (26) trapped and sealed between the shells (12, 14), and compression structure (50, 52) on the inner side (44a) of the peripheral edge (26) of the diaphragm (20a) reducing the amount of diaphragm material requiring compression and also increasing the compression of the bulge (42) of the peripheral edge (26) of the diaphragm (20a) in the bulge (34) of the upper wall section (18) of the lower shell (14) to enhance the seal thereat.  The compression structure includes one or more internal ribs (50, 52) on the inner side (44a) of the peripheral edge (26) of the diaphragm (20a) such that the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) compresses the internal ribs (50, 52) and subjects the bulge (42) of the peripheral edge (26) of the diaphragm (20a) to a direct force to provide the noted increased compression of the bulge (42) of the peripheral edge (26) of the diaphragm (20a), and such that the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) engages and compresses the first rib (50) to apply a radial outward force compressing the peripheral edge (26) of the diaphragm (44a) radially outwardly against a tapered wall portion (54) of the upper wall section (18) of the lower shell (14) which also compresses the peripheral edge (26) of the diaphragm (44a) downwardly into the widest radial area portion of the bulge (34) of the upper wall section (18) of the lower shell (14) to enhance the seal thereat, all while still maintaining ease of telescoped assembly of the shells (12, 14), and such that the radial force on the ribs (50, 52) from the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) is allowed to spread the ribs (50, 52) axially into less compressed areas (74, 82) to enable the noted reduction in the amount of diaphragm material requiring compression.

Title: Context-dependent call-feature selection
Inventor: BOGART FRANK JEFFREY
IPC: H04Q3/00
Filed: 1992-08-21
Granted: 1996-11-26
Abstract: Which call feature module, if any, is invoked in response to a user's input of a feature access code is made dependent upon the context in which the feature request is made, in a call-processing arrangement (200) that uses storeddefinitions of syntax (320, 350) and grammar (400, 410) of the network numberingplan. The syntax definitions are definitions (312) of individual symbol strings,including the feature access codes, and include the string's associated virtual node-point identifier (VNI 334) which indicates the string's influence on feature selections. A VNI (254) resulting from the VNIs of symbol strings included in the entire symbol sequence input by a user serves, along with parameters (1230, 1231, 1232) of the context, as a multi-dimensional pointer into a matrix (1202) of feature numbers (1203). The feature module (205) which corresponds to the feature numberpointed to in the matrix by the pointer is then invoked and executed to provide a corresponding call feature.

The layer structure is an inside region surrounded by a lightning defect generated in the uniaxial orientation direction and a hair-pin defect generated behind the lightning defect or an outside region surrounded by the hair-pin defect generated in the uniaxial orientation direction and a lightning defect generated behind the hair-pin defect. The liquid crystal can invert to switch an orientation axis near the substrates, and the ratio of an angle d of inclination of a layer of the liquid crystal to the substrate, to a tilt angle .THETA. is made to be from 0.9 to 1.

Title: High power light source
Inventor: RAVEN ANTHONY
IPC: G02B27/00
Filed: 1991-08-01
Granted: 2001-10-16
Abstract: An optical system for producing a high power light source comprises a number of laser diodes, or similar sources, which emit light from an emission stripe (8) having a long dimension a (x-axis) and a short dimension b (y-axis) and which have a high-er numerical aperture in the y-axis than in the x-axis. The laser beams (9) are collimated by a lens (10) and focused onto an opti-cal fibre by a further lens (20). Prior to the focusing, the collimating beams (11) are anamorphically expanded/reduced by beam shaping means (12) so that the width of each beam (11) in the x-axis is increased in relation to the width in the y-axis. The images (21) produced on the fibre end are thus anamorphically magnified so that the anamorphic ratio between the magnification of the stripe (8) in the y-axis and in the x-axis is greater than one. By the brightness theorem, this anamorphic magnification results in a correspondingly relative decrease in the y-axis numerical aperture to enable a corresponding increase in the number of beams (11), which can fit into the solid angle of the target.
