Abstract: This invention relates generally to the processing of orthogonal frequency
division multiplex signals, and more precisely methods of synchronising a
receiver of an incoming orthogonal frequency division multiplex (OFDM)
signal. 
     The invention provides methods and apparatus for synchronising a receiver
to an incoming multi-carrier signal, such as an OFDM signal. By making use
of inherent redundancy within the prior art method, significant reductions can
be made in terms of processing power, speed of execution and accuracy.

Inventor: AHUJA SUDHIR RAMAN
IPC: H04L12/28
Filed: 1998-09-08
Abstract: Enhanced Internet service is provided over an ISDN line by eliminating from
the D-channel any packets that will introduce unacceptable delay in packets
transmitted over the B-channel. The enhancement is achieved by segregating the
packets between the B-channels and the D-channel based on the stream to which the
packets belong. Furthermore, instead of bonding together both B-channels and the
D-channel, only the B-channels may be bonded to each other, while the D-channel is
kept independent. To do so, instead of using MLPPP over the combination of both
B-channels and the D-channel, as in the prior art, MLPPP is used over only both
B-channels, while data that is separately directed to the D-channel employs another
protocol, e.g., PPP. Advantageously, the number of protocols used to transmit the
information over the D-channel may be reduced, resulting in a higher bandwidth for
applications. The bandwidth of the D-channel can be dynamically throttled by an
access server. Such throttling can be used to prevent the access server, or the packet
switch in the central office switch that is serving the ISDN line, from being flooded.
The central office switch supporting the ISDN line may be supplemented to support
frame relay over the D-channel, which can provide performance improvement. The
frame relay packets are automatically routed to the access server. Packets may also
be limited to being sent only over the D-channel.

Abstract: L'invention concerne un accélérateur d'ions destiné à être utilisé dans un implanteur à faisceau ionique. Cet accélérateur forme des faisceaux de l'ordre du milliampère d'ions lourds tels que du bore et du phosphore, selon une configuration dans laquelle la source d'ions terminale est remplacée par un injecteur de faisceau neutre. Ce faisceau neutre est formé à la terre par la conversion d'un faisceau focalisé d'ions positifs en ions neutres, dans un canal d'échange de charge. Le faisceau neutre ainsi formé est appauvri d'un ou de plusieurs électrons dans un canal rempli de gaz ou de vapeur, à l'intérieur de la borne haute tension. Un analyseur magnétique à 180°, situé dans ladite borne haute tension, analyse et oriente un état de charge sélectionné vers un tube accélérateur parallèle au tube injecteur de faisceau neutre, dans lequel les ions positifs sélectionnés sont accélérés jusqu'au potentiel à la terre. Afin d'étendre la portée de l'accélérateur en-deçà de l'énergie d'injection, un isolateur haute tension permet d'isoler le côté terre du tube accélérateur d'ions positifs, ce tube accélérateur et la borne étant ainsi uniformément polarisés à une tension négative, ce qui permet de ralentir la vitesse du faisceau à de très faibles énergies et en un endroit proche du point d'utilisation. Dans un autre mode de réalisation, un ensemble accélérateur comprend un analyseur magnétique à 90° dans la borne haute tension.

Abstract: A description is given of an apparatus and a detection unit for sanning an optically readable record carrier (1), in which a light beam modulated by the information marks in a track on the record carrier is incident on the detection unit (15) comprising four detectors. A reliable tracking error signal based on time differences between detector signals is obtained for high-density recording by comparing digitized signals of the detectors with a delayed signal Td generated by delay unit (45) based on the digitized signals. The time differences between the detector signals result in length differences between pulses in the comparing signals A and B, which pulses have a nominal length of Td. The comparing signals A and B are low-pass filtered and combined to generate the tracking error signal TE.

Abstract: A signal strength for a received signal such as a radio signal transmitted over a communication network is determined. The signal strength measurement is compensated for non-linear characteristics of the receiver. The compensation is provided by taking two signal strength readings with the receiver set at two different, known, gain levels. The difference between the expected change in the signal strength and the change actually measured by the receiver is used to generate a compensated signal strength measurement. A table of compensation factors is generated for each signal strength which is also utilized in generating the compensated signal strength measurement. The compensated signal strength measurement reading is transmitted to the communication network for use in mobile assisted handover.

Abstract: Description of a process and a circuit for the linearization of the transfer
characteristics of a commonly available analog-to-digital converter. In a first realization
modality are used a training signal with a known probability distribution of the
amplitudes and a processor applying the Code Density method on the codes
generated in order to estimate the threshold values to be corrected. The corrected
values generate words which are longer than the original ones which will be written in
a mapping memory at the address specified by the shorter original words. Once the
calibration step is finished the mapping memory will be put on line downstream of the
converter and addressed as said just before. In a different realisation version a
second analog-to-digital converter is used in parallel to the first one, which is slower
and more precise than the latter, to generate directly the corrected words with a
greater length to be written in the mapping memory. A second memory on line
enables the adaptive functioning.

Abstract: The present invention provides a method for keeping a file system in a consistent
state and for creating read-only copies of a file system. Changes to the file system
are tightly controlled. The file system progresses from one consistent state to
another. The set of self-consistent blocks on disk that is rooted by the root inode is
referred to as a consistency point. To implement consistency points, new data is
written to unallocated blocks on disk. A new consistency point occurs when the
fsinfo block (2440) is updated by writing a new root inode for the inode file (1210)
into it. Thus, as long as the root inode is not updated, the state of the file system
represented on disk does not change. The present invention also creates snapshots
(Figure 22) that are read-only copies of the file system. A snapshot uses no disk
space when it is initially created. It is designed so that many different snap shots can
be created for the same file system. Unlike prior art file systems that create a clone
by duplicating the entire inode file and all of the indirect blocks, the present
invention duplicates only the inode that describes the inode file. A multi-bit free-block
map file (1630) is used to prevent data from being overwritten on disk.

Abstract: Provided is a lamp lighting and battery charging control system for
a vehicle which can favorably use the electric power produced from the
engine-driven electric generator in both lamp lighting and battery charging.
According to one embodiment of the present invention, the conventional
full-wave and half-wave techniques are performed alternately in every
other cycle of the AC voltage from the generator. Thus, the lamp is
lighted alternately by a full-wave and a negative half-wave of the AC
voltage in every other cycle, ensuring sufficient luminous intensity of the
lamp even at low engine speeds, while every other positive half-waves
which can be used exclusively in charging the battery can prevent
insufficient battery charging at low engine speeds. According to another
embodiment of the present invention, the turning on of the switching
device for controlling the electric current of the lamp is gradually delayed
so that the time duration of the electric current flowing through the lamp is
gradually decreased as the engine speed increases, preventing an excessive
electric current from damaging the lamp in the high engine speed range.

Abstract: A method and system for optically recognizing an object from a reference library
of known products based on a spectrum of local radius of curvature of the object. A
surface portion of an object is illuminated with a pattern of light that permits the
extraction of three dimensional coordinates for a set of points on the surface portion of
the object. An image data set of the surface portion of the object is then captured with a
capture device that is positioned at an angular offset with respect to a source of the light.
That is, the combination of the light pattern and the imaging device together generate a
two dimensional captured image, from which it is possible to extract the three
dimensional coordinates for the set of points on the surface portion of the object. A set
of local radii of curvatures are then determined for selected data points in the image data
set. A spectrum representing a distribution of the curvatures is then computed for the set
of local radii of curvatures. If the data set is for the generation of a library of spectra, it is
processed with a dimension reduction analysis to determine a single set of basis functions
representing all of the objects and a corresponding set of basis coefficients for each
different type of object. If the data set is for an unknown object, then the dimension
reduction analysis and the basis functions are applied to the data set to generate an
unidentified set of basis coefficients. This latter set is then statistically compared with the
reference library of spectra to identify the product or at least designate the closest known
products.
