Patent EP-0767528-A3 (EP)
Inventor: FITZGERALD WILLIAM VINCENT
IPC: H02M3/28
Filed: 1996-10-02
Abstract: In a tuned switch mode power supply a zero voltage is
maintained across a transistor switch (Q3), during both turn off
and turn on switching transition intervals in the transistor switch.
The tuned switch mode power supply operates in a current-mode
control, on a current pulse-by-current pulse control basis. A
modulator (31) of the power supply includes a pair of transistors
(Q1, Q2) that form a regenerative switch to produce a portion of a
control signal (VG) of the transistor switch that causes the
transistor switch to turn off. A transformer-coupled input supply
voltage (V1) maintains the transistor switch conductive as long as
the current in the transistor switch does not exceed the threshold
level of a regenerative switch. A resonant pulse (VD) is
transformer-coupled from the resonant circuit to the regenerative
switch for turning off the regenerative switch and for maintaining
the transistor switch non conductive after the regenerative switch
is turned off.

Abstract: A pixel of a color video image is converted from one color format having
luminance and chrominance signals, e.g., YUV format, to a destination format, e.g.,
RGB or CMY formats, by forming luminance and chrominance component words
which include partitioned words representing various color components of the
luminance and chrominance signals. The luminance and chrominance component
words are summed using a partitioned addition operation to thereby accumulate the
various color components of the luminance and chrominance signals simultaneously
and in parallel. Formation of the luminance and chrominance component words is, in
some instances, done by a load and store unit of a central processing unit while a
graphics execution unit simultaneously sums the luminance and chrominance
components using the partitioned addition operation. By using this technique,
conversion of pixels of a color motion image from YUV format to a different formate,
e.g., RGB format, is reduced from approximately 20 instruction cycles per pixel to
generally less than 2.5 instruction cycles per pixel. Such a reduction in processing
requirements has enabled full real-time rendering, e.g., thirty frames per second, of
full-sized, digital NTSC, MPEG-compressed, motion video images using only a
central processing unit and appropriately configured computer software. No
additional, special-purpose hardware components were needed.

Abstract: The security procedure makes use of a smart card held by an authorised subscriber. The card is inserted into the terminal to allow it to operate. There are two modes, a normal mode when any authorised card need only be inserted into the terminal and a locked mode, when the terminal can be used only with a specific card. The smart card has locking data stored in a particular part of its memory. When operated in locked mode there is an initial stage of authentication of the user card carried out by the terminal. The terminal applies an algorithm to the data read from the card, and allows operation only if the result matches a values stored in the terminal.

Abstract: In conduit scraping conveyors, e.g. for conveying food to
a plurality of feeding places in a stable, a flight conveyor
cable is advanced through a tubular system for forwarding
material by the help of flight discs on the cable. The cable
should be a cored steel cable, that however has a tendency of
expelling wire pieces that in an extremely undesirable manner
is mixed with the material. Steel cables are already known
that are surrounded by a covering layer of extruded elastomer
that could prevent the release of wire pieces, but these
cables are not immediately suitable for being provided with
moulded flight discs that ought to be in firm connection
directly with the steel cable. 
     It is by the invention realised that a cover coated
flight conveyor cable however can be provided by making use
of an injection moulding technique, by which the flight discs
(2) in a known manner is moulded in a relatively stiff or
rigid elastomer directly on the steel cable (1), but also
having short thin outwardly extending sockets (2a) at both
sides of the flight discs (2), and that there between the
neighbouring flights (2) and over the sockets (2a) is
moulded a bendable elastic coating layer (3), preferably a
thermoplastic elastomer, as this can retain its tight
connection to the sockets (2a) and the cable (1).

Abstract: A video camera using a disk-type recording medium is
capable of allowing the user to extend the remaining record
time easily. In the control sequence, step 2 detects whether
the record time extension key is pressed. The sequence
proceeds to step 3 if the key is pressed, or otherwise proceeds
to step 5. Step 3 calculates the extendable remaining record
time and displays it. When the storage space runs out during
the recording of the video signal of an intended shot scene,
step 4 searches for the largest record area or nearest record
area of unwanted scenes based on management information which is
recorded on the recording medium for the video signal of each
shot scene, moves the recording head to the area, and records
the video signal of intended scene continuously by overwriting
in the area. Step 5 detects whether the record time remains.
The sequence proceeds to step 6 to terminate the recording
operation if the record time runs out, or otherwise returns
to step 2. Management information including record positions
of video signals is stored temporarily in the memory, and it
is recorded in the management information area of the recording
medium when the recording is halted or terminated.

Abstract: A method and system for providing controlled access to information stored on a
smartcard. The system includes a data processing center maintained by a trusted third
party for storing a database of authorizations of various service providers to access
information pertaining to individuals, and for responding to request by service providers
for access from terminals which communicate with the data processing center and
smartcards storing the individuals' information. The information is stored on the smartcard
in encrypted form and the data processing center provides an access code, which includes
a key for decrypting the information, only to service providers who are authorized to
access the information. The service provider then sends the access code to the smartcard
which verifies the access code and decrypts and outputs the requested information. The
smartcard then computes a new key as a function of information unique to each access
session and uses the new key to re-encrypt the information, and then erases the new key.
The data processing center also computes the new key so that the data processing center
can provide an access code including the new key for the next request for access.

changes the information signal represented by the compressed input bitstream, and comprises
a layered decoder (114, 714A) that decodes the compressed input bitstream to provide a
decoded bitstream (116, 716A), a decoded bitstream processor (118, 718A) that processes the
decoded bitstream to provide a modified bitstream (122, 722A), a layered encoder (124, 724)
that re-encodes the modified bitstream to provide a compressed output bitstream (126, 726),
and a selective interconnection path (134, 215, 315, 138; 725, 721, 719, 738). The layered
decoder includes serially-connected decoding modules (e.g., 201, 203, 705, 707). The decoded
bitstream processor processes the decoded bitstream in a way that modifies the information
signal. The layered encoder includes serially-connected encoding modules (e.g., 301, 303, 705,
707), each of which corresponds to one of the decoding modules in the layered decoder. The
selective interconnection path selectively connects the output of one of the decoding modules
to the input of the decoded bitstream processor and selectively connects the output of the
decoded bitstream processor to the input of the one of the encoding modules corresponding to
the one of the decoding modules. The layered decoder may include an element that derives
bitstream parameters from the compressed input bitstream, and the apparatus may additionally
comprise a bitstream parameter forwarding path that interconnects the layered decoder to the
layered encoder. At least one of the encoding modules may be connected to the parameter
forwarding path and may perform an encoding operation using the bitstream parameters derived
from the compressed input bitstream.
