Patent EP-0441642-A3 (EP)
Title: Methods and apparatus for spectral analysis
IPC: G10L11/00
Filed: 1991-02-08
Abstract: In automatic speech recognition it is usual to make a spectral analysis of the incoming speech signal and it can be useful to detect the frequencies and intensities of the formants. However although the formants are mostly quite well defined during vowel sounds there are frequent occasions when this is not so and it is not so during a high proportion of consonant sounds. The present invention determines the frequencies at which the centroids of respective frequency versus power distributions occur in a plurality of frequency bands of a signal representing speech (approximately corresponding to the ranges of individual formants). The centroids have most of the desirable properties of formants but also carry significant information for those sounds for which the conventional definition of formants does not seem appropriate. Preferably the powers in the bands in which the centroids are measured are also determined. The incoming signal is filtered (2) into separate frequency bands and the power in each band is measured (4). The output signal in each band is weighted by 3 dB per octave (5) and then the power in that band is measured (6). The power ratio obtained (7) for a band from the power after 3 dB weighting divided by the power before weighting gives an indication of the position of the centroid of that band in the frequency spectrum. <IMAGE>

Patent EP-0484315-A3 (EP)
Title: Injection mould
IPC: B29C45/44
Filed: 1991-10-30
Abstract: An injection mould comprises a mould core (3), which has, for producing an inner bead (6) in a pipe fitting (5), an annular ring which can be pushed in and out for forming the bead. The annular ring comprises a first and a second segment group (7, 8). The segments (7', 8') alternately adjoin one another. Each segment (7', 8') is carried by an angle lever (13, 26), the radial lever arm (14, 29) of the same respectively engaging in a longitudinal groove (11, 12), assigned to each segment (7', 8'), of an annular sleeve (9), which can be displaced hydraulically along a cylindrical core support (4). During the pushing-back of the annular sleeve (9), the segments (7', 8') of both segment groups (7, 8) are first of all disengaged, then an end face (22) of the one groove (11) strikes the radial lever arm (14) of the first segment group (7) and swings the latter inwards. During further pushing-back, the annular sleeve (9) takes with it the complete angle lever (13), which is pivotably mounted on an axially displaceable ring (20), and draws the first segments (7') axially back. Shortly before the end of the slideway of the annular sleeve (9), the end face (30) of the other groove (12) strikes the radial lever arm (29) and swings the segment (8') of the second segment group (8) into the interior of the core. <IMAGE>

Title: Nuclear medicine imaging apparatus
Inventor: KUMAZAWA YOSHIHIKO
IPC: G01T1/164
Filed: 1993-09-23
Abstract: A first image collection memory collects two-dimensional 
image data within a predetermined energy 
window to constitute a fine matrix. A second image 
collection memory collects three-dimensional image 
data, including energy spectral information, to constitute 
a coarse matrix. Each pixel of the data collected 
in the second image collection memory is subjected to a 
scatter correction with energy weighted acquisition 
using a weight function. A correction coefficient is 
derived from a ratio between data before the correction 
and data after the correction. A further correction 
coefficient is obtained by interpolation processing for 
each pixel in the fine matrix, and is applied to the 
image data collected in the first image collection 
memory.  
     The data collected in the second image collection 
memory is subjected to two-dimensional low-pass filter 
processing. The scatter correction with the energy 
weighted acquisition is effected for each data collected 
in the second image collection memory such that, for 
an energy range having a value of the weighting function 
equal to or above a predetermined value, the 
function is applied to the data before the filter 
processing, and for an energy range having a value of  
 
the function below the predetermined value, the function 
is applied to the data after the filter processing.

Title: Arc welding torch for welding under protective gas.
Inventor: WILLMANN EDWIN
IPC: B23K9/29
Filed: 1994-03-22
Abstract: The arc welding torch for welding under protective gas is provided with a contact tip (1) which is fastened to a receptacle (2) forming the end of a tubular cooling body (3, 4) and having an annular coolant passage (5) for carrying away the welding heat. In its end facing the receptacle, the contact tip has a fastening bore whose side walls surround on the outside the receptacle section containing the annular coolant passage. To fasten those components which are subjected to especially high thermal stress, namely the contact tip and possibly a wear insert (10) and the gas nozzle (16), a special rotary taper is provided. This rotary taper is formed by spiral segmental surfaces (7, 8 and 14, 15 or 20, 21) between the corresponding components to be connected to one another. These spiral segmental surfaces permit easy and releasable connection of the corresponding components, for example between the contact tip (1) and the receptacle (2), in which case contact over a large area takes place at the same time, which provides for good heat conduction. <IMAGE>

Title: Coded signal formatting for encoder and decoder of high-quality audio.
Inventor: FIELDER LOUIS DUNN
IPC: H04B1/66
Filed: 1990-01-29
Abstract: An encoder applies a digital filterbank such as a transform or subband filterbank to an input signal to generate frequency subband information, encodes the resultant subband information using adaptive bit allocation to generate fixed-length values represented by fixed numbers of bits and variable-length values represented by variable numbers of bits, and formats the subband information into an encoded signal in which the fixed-length values are assembled into preestablished positions within the encoded signal. In response to an encoded signal including subband information represented by fixed-length values and variable-length values, a decoder extracts fixed-length values represented by fixed numbers of bits from preestablished positions within the encoded signal, extracts variable-length values represented by variable numbers of bits, wherein the variable numbers of bits are established in response to fixed-length values, and generates an output signal by applying an inverse filterbank to the extracted subband information. <IMAGE>

Title: Installation raceway.
Inventor: PEETZ MATTHIAS
IPC: E04F17/08
Filed: 1994-08-02
Abstract: The invention relates to an installation channel (installation duct) (3) for laying electrical cables, having a base (32) and two side walls (33, 34) which are integrally connected to this base (32). On their free edges, the side walls (33, 34) have wall regions (1, 2) which are directed such that they run longitudinally at right angles to the channel interior (31) and are designed as mounting points for installation links, cable brackets or similar installation aids. The invention is regarded as being that the wall regions (1, 2) have bends (11, 12), which run such they converge towards one another, at their free ends into the cable interior space (31). The installation brackets (4), in contrast, have forked-shaped offsets (41, 42), which point away from one another in a divergent manner, at their free ends. The fork openings (411, 412) of these fork-shaped offsets (41, 42) point towards the bends (11, 12) and their unobstructed fork width corresponds to the cross-sectional dimensions of the bends (11, 12).

Abstract: A physically realizable one terabit or more ATM packet switch 10A that has a
large number of input interfaces connected to a single stage switching fabric 14A
which is in turn connected to a number of output modules 16 0 -16 m  , according to the
generic growable packet switch architecture. This ATM packet switch 10A is
different from other growable packet switches in that it has a single stage switch
fabric (14A or 14B) controlled by an out-of-band controller 20, yet it has significantly
reduced complexity with respect to comparably sized electronic crossbar switches or
their isomorphs. This ATM packet switch architecture is so flexible, it can be
extended to provide variable length packets, circuit switched connections and fault
tolerant redundant circuits using the same switch fabric and out-of-band controller
architectures.
