IPC: G06F9/52
Filed: 1998-03-13
Abstract: A system for fast, efficient and reliable communication of
object state information among a group of processes combines the
use of a fast, but lossy and thus unreliable communications
channel to the group of processes and a server (50) coupled to the
group (10,12,14) for providing data which has been lost in the multicasting.
In one embodiment, a central server (50) supports reliability and
rapid joining while using UDP multicast messaging to achieve
rapid interaction and low bandwidth. Differential messages (58) are
sent over the lossy channel to compactly describe how to compute
the new state of an object from any of several previous states.
Such a description can be interpreted even if some number of
prior descriptions were not received, greatly reducing the need
for explicit, round-trip message repairs while also conserving
bandwidth. In one embodiment, the central server (50) communicates
with each member of the group (10,12,14) over a reliable channel to
robustly detect and repair objects affected by lost messages.

Title: Frequenzteiler mit geringem Stromverbrauch
Inventor: KNAPP HERBERT
IPC: H03K23/66
Filed: 1998-09-07
Abstract: Der Anmeldungsgegenstand betrifft einen Frequenzteiler mit
einem zwischen 1/N und 1/(N+1) umschaltbaren Teilungsfaktor
und einer Eingangsfrequenz von ca. 1 Ghz, wie er beispielsweise
in mobilen Telekommunikationssystemen (GSM- oder DECT-Telefon)
vorkommt. Der hierdurch erzielte geringe Stromverbrauch
resultiert in erster Linie daraus, daß nur das Eingangs-Flipflop
(FF1) die relativ hohe Eingangsfrequenz verarbeiten
muß und ein Zwischensignal (1) mit der halben Frequenz
entweder direkt oder invertiert einer Teilererweiterung (EXT)
zugeführt wird.

Patent EP-0921028-A3 (EP)
Inventor: JONES CHRISTOPHER CHARLES
IPC: H02P27/06
Filed: 1998-11-20
Abstract: A hill-holding arrangement for an
electrically driven vehicle includes a vehicle with a
"gas pedal" which generates a torque command signal
T CMD . A switch (314) couples T CMD  to a motor controller
(316, 14) which drives the motor (40) and therefore the
vehicle. When the "gas pedal" calls for zero torque,
and the vehicle speed is zero, the switch responds to
logic (FIGURE 5), and substitutes a position-holding
torque command signal T   for the operator-controlled
torque command signal T CMD . Position controlling torque
command T   is generated by a controller (312) which
receives a position signal representative of the
angular position  of the rotor. The position-holding
torque control loop then produces such torque as may be
required to prevent the rotor of the motor from moving
from its commanded position.

IPC: F16H61/21
Filed: 1998-12-18
Abstract: A continuously variable transmission controller for controlling a
continuously variable transmission mounted on a vehicle, whereby
a decision is made as to whether a vehicle is traveling in an
uphill traveling mode or in a downhill traveling mode with reference to
an incremental running resistance ΔR determined on the basis of a
running resistance that will act on the vehicle while the vehicle is
traveling in a flat road traveling mode. A desired traction F d  for a
full-open throttle state in which a throttle valve is fully open is set if
the vehicle is in the uphill traveling mode by using the incremental
running resistance ΔR, and a desired traction F d  for a full-closed
throttle state in which the throttle valve is fully closed is set if the
vehicle is in the downhill traveling mode by using the incremental
running resistance ΔR. The desired traction F d  and an achieved
traction F(t) in the full-open throttle state at a present traveling speed
V are compared if the vehicle is in the uphill traveling mode. The
desired traction F d  and an achieved traction F(t) in the full-closed
throttle state at a present traveling speed V are compared if the vehicle
is in the downhill traveling mode. A speed change ratio correction Δr is
set to adjust the achieved traction F(t) to the desired traction F d . Data
on desired primary pulley speed NP stored in a basic speed change
characteristic map is shifted by the speed change ratio correction Δr
toward a downshift side for correction, and a desired speed change
ratio i s  is set on the basis of the corrected data on desired primary
pulley speed NP.

Title: Image coding apparatus and method using pattern coding
Inventor: HIRAO KOUICHIROU
IPC: H04N19/94
Filed: 1998-12-23
Abstract: An image coding apparatus having a high compression
ratio is disclosed. A matching processing circuit matches an
input pattern from a pattern storage circuit with a reference
pattern from a library circuit. Based on a determination
result produced by a matching result determination circuit, a
selector selects its output to be sent to a coding circuit.
That is, when the matching result determination circuit has
determined that the input pattern and the reference pattern
do not match, the selector selects the input pattern and
sends it to the coding circuit for coding. On the other
hand, when the matching result determination circuit has
determined that the input pattern and the reference pattern
match, the selector selects an error map and sends it to the
coding circuit for coding. Therefore, when the two patterns
match, the apparatus codes only the difference between the
input pattern and the reference pattern, thus increasing the
compression ratio of the input pattern having a matching
reference pattern and, therefore, increasing the compression
ratio of the whole image.

Abstract: A method for sending a secure message in a telecommunications system utilizing
public encryption keys. All authentication parameters of each of the users, including
each user's decryption key that is known only to the user, are used to verify, by
public key methods, the identity of a user sending a communication to another user
of the system. During the authentication process, an encryption key for use in
communications between the two users may also be generated. The generated
encryption key may be a private session key. Once the initial authentication is
completed, the private session key can be used to perform encryption that is less
computationally demanding than public key methods. 
     In an embodiment of the invention, two communicating users may use the method to
authenticate each other and generate an encryption key that is used to encrypt
subsequent communications between the users. During the process of this
embodiment, two encryption keys are generated. A first encryption key is used only
in the authentication process, and, a second encryption key is used in both the
authentication process and as the key for encrypting subsequent communications.
Use of two encryption keys requires that each of the two users apply its decryption
key to complete the authentication and encryption key agreement process
successfully.

Abstract: Graphics software for use in rendering an image on a computer display.
The software is most preferably used in conjunction with special hardware
including a high resolution computer monitor and high speed graphics imaging
software. The software allows the user to create and manipulate paint objects
that define the way images are modified by rendering tools such as a drawing
tool or a titling tool. The attributes for a plurality of paint objects are defined in a
hierarchy and can be stored on a memory device such as a computer hard
drive. The organization into a hierarchy of the various attributes making up a
complex object such as a paint stroke or a text body result in an ability to deal
with branches of the hierarchy as persistable objects in their own right.

Abstract: The invention provides a display state detection method which
allows the display state of an information display apparatus to
be supervised accurately without giving any obstacle to a user,
a display state adjustment method and a maintenance management
method by which the display state can be kept good.
Optical sensors are disposed
on the rear face side of a plasma display panel and catch rear
face side outgoing light, which increases in proportion to the
outgoing light amount to the display face side of the plasma
display panel. The sensors detect a panel display state, and the display
state of the plasma display panel is automatically adjusted
based on a result of the detection. When adjustment is
impossible, the apparatus itself outputs an alarm and
accumulates an adjustment history and/or a failure history.
The presence of the optical sensors does not make an obstacle
when the display screen is observed, and there is no need to
effect operation to arrange an optical sensor and connect it to
an adjustment equipment for exclusive use each time adjustment
is to be performed. Since the display state of the plasma
display panel is detected directly by the optical sensors, the
accuracy in detection is high.

Abstract: A shielded needle assembly (10) has an elongate needle (12) that defines an axis having a pointed
distal end (14), a proximal end (16) and a passageway (18) therethrough. The assembly (10) also has a hub (20,20a) that is
mountable on a fluid handling device (24) with an axial opening (22) therethrough to receive the needle (12)
with the distal end (14) projecting outwardly therefrom so that the fluid handling device (24) is in fluid
communication with the passageway (18). The hub (20,20a) has an annular weakened area (26) therein that
defines a needle portion (28,28a) and a fluid handling device attachment portion (30). The assembly (10) further
includes an elongate shield (32,32a) with a proximal end (34), a distal end (36) and a sidewall (38) that defines a
cavity (40). The shield (32,32a) has a slot (42,42a) extending from the proximal end (34) to the distal end (36). The shield (32,32a) is
attached to the needle attachment portion (28,28a) of the hub (20,20a) with a hinge (44,44a) that provides for pivotal
movement of the shield (32,32a) between an open position where the pointed distal end of the needle is
exposed for use and a closed position where at least the pointed distal end (14) of the needle (12) is
disposed within the cavity (40) through the slot (42,42a) and is substantially protected from inadvertent
exposure. In the assembly of the invention, the needle portion (28,28a) and the fluid handling device
attachment portion (30) of the hub (20,20a) are frangibly detachable from each other at the annular
weakened area (26) by a force applied to the assembly (10) transverse to the axis (A) and distal to the
annular weakened area (26).

Abstract: During the low load operation, this fuel injection
control device reduces the initial armature (44)
displacement speed of the solenoid actuator(2) that
drives the open-close valve(5) against the low fuel
pressure in the balance chamber(30), thereby lowering
impact noise produced in the solenoid portions (40,41).
When the engine is determined to be idling, a command
pulse width(Pw) which energizes the solenoids (43) of
the solenoid actuator(2) is calculated according to the
target injection amount(Qb), the common rail pressure
(Pc), and the target fuel injection timing(Ti). Since
the initial period of the command pulse width(Pw), i.e.,
pull-in current conduction period(Pwpi), is set shorter
than the pull-in current conduction period(Pwpi) for
the high load operation of the engine, the initial
armature (44) displacement speed of the solenoid(43)
becomes relatively slow reducing the impact noise of
the armature (44) abutting against the stopper.

Abstract: The semiconductor module has a compact antenna element (25) capable
of providing desired directivity. When an electromagnetic-wave radiation window
has the capability of a lens, directivity can be set arbitrarily. For improving
directivity, a convergent lens for converging millimeter waves or quasi millimeter
waves is employed. For impairing directivity, a divergent lens is employed. In the
case of the convergent lens, a direction in which radio waves are radiated or
received by the antenna element can be set by deviating the center axis of the lens
from the center of the antenna element.

Abstract: The image reading apparatus of the invention has a
changing means between ordinary image reading mode and
fine reading mode. And, in the fine reading mode, when the
moving speed of the carriage carrying the photoelectric
converter is set to 1/n of that of the ordinary reading mode,
the number of times of the signal data being read out from the
photoelectric converter is set to 1/n of that of the ordinary
reading mode. So that lowering of resolution in the carriage
moving direction is prevented. The image reading apparatus
of the invention allows the users to change between arbitrarily
the ordinary image reading mode and fine reading mode, and
allows the users to select the value of n to be selected
arbitrarily depending on the desired resolution of the image.
