Patent EP-0913929-A2 (EP)
Inventor: KROCHMAL ANDREW CYRIL
IPC: H03F3/68
Filed: 1998-10-05
Abstract: A high output power is obtained for an audio power amplifier using an amplifier circuit topology wherein channels or stages of a multi-channel class AB monolithic integrated circuit (35) are paralleled in order to drive a low impedance dual voice coil speaker. The stages are paralleled by connecting their outputs through isolation resistors (40,41). These resistors prevent the differences in output bias voltages from resulting in a short circuit from power to ground. In addition, the resistors (40,41) are sufficiently small to achieve the correct speaker damping factor, yet large enough to prevent excessive quiescent current. The separate amplifier channels or stages are paralleled through isolation resistors which increases current drive resulting in a higher output power to the loud speaker.

Abstract: An intake and exhaust system for use with lean-burn combustion engines includes a
first intake port and a second intake port that transfer a fuel-air mixture to a combustion chamber
within a cylinder. At least one exhaust port allows combustion gases to exit the combustion
chamber. Preferably, in the intake and exhaust system, a first exhaust port and a second exhaust
port are located on diagonally opposite sides of the cylinder. The first intake port preferably
transfers a fuel-air mixture to the combustion chamber in a direction opposite of the second intake
port. When two exhaust ports are used, it is preferable that the first exhaust port transfers gas
outside of the combustion chamber in a direction opposite of the second exhaust port. The location
of the input and exhaust ports creates a strong swirl under a range of loads.

Abstract: A bit synchronization circuit used in a receiver circuit for serial
communication includes a sampling unit (101) which performs
oversampling of a received signal at a sampling rate higher than bit rate to
output the result of the sampling in parallel at a rate lower than the
sampling rate, and a state machine (102) which determines and outputs the
number of bits and content of received data based on sampled data supplied
from the sampling unit (101) and internal state. The sampling unit (101)
performs oversampling of a received signal at a sampling rate higher than
bit rate so that synchronization with the received signal can be established
at high-speed and correction to the synchronization can be made at each
transition point of the received signal. Further, the sampling unit (101)
and the state machine (102) can be configured of digital circuits and thus
are suitable for mass production, If the sampling unit (101) performs
oversampling using a group of multi-phase clocks, a bit synchronization
circuit which requires no high-speed clock can be implemented.

Abstract: In variable mode in which clutches (15, 21) are locked
and a clutch (16) and a brake (65) are unlocked, the power of
an input shaft (11) is branched to a traction transmission
mechanism (27). By contrast, in fixed mode in which the
clutches (15, 21) are unlocked and the clutch (16) and the brake
(65) are locked, the power of the input shaft (11) is not
branched to the traction transmission mechanism (27). In this
way, the fixed mode in which the power is transmitted
irrespective of the traction transmission mechanism (27), and
the variable mode in which the power is branched to the traction
transmission mechanism (27) are selectively used, whereby
noise reduction and enhanced fuel efficiency can be attained.
According to this configuration, it is possible to provide a
power transmission apparatus for helicopters in which the
number of rotations of a main rotor or a tail rotor is
continuously varied while maintaining the number of rotations
of an engine constant.

Abstract: An antenna system (10) having a front reflector (12)
and a rear reflector (14) arranged in tandem, a front feed
(16) for illuminating the front reflector (12), and a rear
feed (18) for illuminating the rear reflector (14). Each
of the reflectors has a generally dish-shaped
configuration, and the feeds are located in positions
offset from axes of the respective reflectors. The front
reflector (12) is reflective to a first radiation, while
being substantially transparent to a second radiation
except for a fraction of the power of the second radiation.
The fractional part of the second radiation is reflected
from the first reflector (12) as an interfering beam, the
interfering beam being scanned away from a coverage region
of a beam (28) of the first radiation by an offset between
the feeds (16, 18). The radiations may differ in
polarization or in frequency. There may be a complete
shading of the rear reflector (14) by the front reflector
(12) from the radiation of the rear feed (18) to produce
uniform illumination of the rear reflector for greater
accuracy in a formation of a beam from the rear reflector.
Six degrees of freedom in positioning and orientation of
the reflectors (12, 14) and their feeds (16, 18) provides
maximum design flexibility for obtaining a compact antenna.

Abstract: There is presented a method for integrating management functionality in
communications networks by virtue of a design model for constructing a
management information base in a communications network management
system. A unit of manageable physical resources is represented in the
management information base by a management unit. The management unit
comprises a collection of managed objects representing actual physical and
logical resources in the communications network, the managed objects arranged
such that functionality provided by the physical and logical resources is
represented separately and independently from the actual physical and logical
resources themselves, in the particular way in which those resources are
implemented. A unit of manageable functionality and resources is represented in
the management information base by a management unit. A management unit
comprises an Application Model, which represents functionality of those
resources, and an Implementation Model, which represents the actual specific
implementation of how that functionality is carried out. The Application Model
and Implementation Model are related to each other by a set of associations,
presented in the disclosure, termed "realisation associations". A collection of
realisation associations which link an Application Model to an implementation
form a realisation model. Division and representation of physical and logical
resources in the management information base by the management unit method
may enable substitution of physical and logical resources by different
implementations of similar resource components without requiring reconfiguration
of parts of the management information base which represent the
functionality provided by those physical resources. Greater reuse of design and
development effort may be achieved by configuring the management information
base in the method disclosed, and easier maintenance and replaceability of
physical and logical components may be achieved.

IPC: B66F9/18
Filed: 1999-10-07
Abstract: A fluid power load-clamping system includes at least one fluid valve
(74) for variably regulating the maximum fluid pressure causing closure of the
clamp (10). Preferably the valve (74) increases the maximum fluid pressure
automatically in relation to the measured magnitude of the weight of the load to
regulate the load-gripping force. A controller (70) causes the valve (74) to
permit a relatively high maximum fluid pressure as the clamp (10) closes
toward the load to enable high initial clamp closure speed. Thereafter the valve
(74) automatically reduces the maximum pressure as the clamping surfaces
close into a predetermined relationship with the load, and then increases the
maximum pressure to regulate the gripping force. Other preferable features
include continuous weight-responsive automatic regulation of the gripping
pressure while the load is supported by the clamp, and compensation of the
weight measurement for the longitudinally-extensible position of the lifting
mechanism, to maximize the accuracy of the load-weight measurement.
Gripping pressure regulation is operable in response to linear load-lifting or
tilting load-lifting, without concurrent clamp closure actuation. Different
predetermined relationships between the weight of the load and the maximum
gripping pressure are selectable alternatively. A gravity-referenced tilt
controller (82) adjusts the load automatically to an attitude which is untilted
with respect to gravity. Lowering of the lifting mechanism is automatically
prevented in response to the setting down of the load.
