Patent EP-0313057-A3 (EP)
Title: Dual mode phased array antenna system
IPC: H01Q25/00
Filed: 1988-10-21
Abstract: A phased array antenna system (20) having an array 
(22) of radiating elements (24-30), 
such as pyramidal horns, and a 
distribution network (32) connected 
thereto, has a dual mode of operation 
where each mode produces a composite 
beam which can and preferably does 
produce an identical far-field 
electromagnetic radiation pattern. The first 
composite beam is made up of a 
plurality of individual beams, forming a 
linear combination of excitation 
coefficients (a₁ - a₄) that are mathematically 
orthogonal to the linear combination 
of excitation coefficients (b₁ - b₄) of the 
individual beams of the other composite 
beam. A plurality of input ports (42-44) 
are provided, and each composite 
beam is associated with an 
information-bearing input signal 
applied to one of the input ports. The 
distribution network (32) is preferably 
constructed with at least two 
stages of signal-dividing devices such as directional 
couplers and at least a pair of phase-shifting devices. 
By using passive devices, the 
distribution network (32) is substantially 
lossless and reciprocal, and can thus 
also be used for dual mode reception of 
two distinct beams.

Title: Improved vehicle detector method and system
IPC: G08G1/042
Filed: 1988-07-26
Abstract: In an inductive loop vehicle detector, a sample count 
which depends on the loop inductance is compared with 
a reference count in producing a detection signal. In 
order to take account of loop drift, the reference 
count is replaced with the sample count when the 
difference therebetween indicates drift for a 
predetermined period of time.

Title: Spectacle-lens-frame configuration measuring apparatus and article configuration measuring apparatus
IPC: B24B9/14
Filed: 1989-05-30
Abstract: In an apparatus for measuring a configuration 
of each of a pair of lens frames (4a, 4b) of a spectacle 
framework (3), a measuring element (230) is arranged for 
horizontal and vertical movement relative to the lens 
frames fixedly held by a holding device (100). The 
measuring element is movable angularly about an optional 
reference point (O) within one of the lens frames, along 
an inner periphery of the lens frame, while causing the 
measuring element to be in contact with the inner 
periphery of the lens frame. A first detector unit 
(224) detects horizontal straight displacement (r) of 
the measuring element from the reference point. A 
second detector unit (233) detects vertical straight 
displacement (z) of the measuring element from the 
reference point. A third detector unit (209) detects an 
angle (ϑ) of the angular movement of the measuring 
element about the reference point. The configuration of 
the inner periphery of the lens frame is calculated on 
the basis of signals from the respective first, second 
and third detector units. Also disclosed are an 
apparatus for measuring a configuration of a 
substantially planar article (500), and a holding device 
for a pair of lens frames of a spectacle framework.

Title: Backflow preventer for sanitary systems, especially for installation in a sanitary fitting
IPC: E03C1/10
Filed: 1989-11-02
Abstract: A pipe interrupter, which is particularly suitable for installation in a sanitary fitting, comprises in a housing a chamber, into which a water-supply passage, a water-discharge passage and a ventilation path open. Located in the chamber is a rolling membrane, which is fixed at the peripheral region. Normally, thus as long as there is no reduced pressure in the supply passage, the rolling membrane bears in the central region against the opening aperture of the ventilation path in the chamber, so that on the one hand no atmospheric air may enter and on the other hand no water may escape. However, if reduced pressure occurs in the pipe system, which is connected to the supply passage, then the rolling membrane overturns so that now on the opposite side of the central region it closes the opening point of the supply passage into the chamber. On the other side, a ventilation path to the chamber is exposed. This ventilation path continues by way of a through-flow opening in the edge region of the rolling membrane towards the discharge passage. In this way, water can no longer flow back into the supply passage and into the pipe system connected thereto; on the other hand, the water-ways following the chamber are ventilated.

Title: User to network interface protocol for packet communications networks
IPC: H04L29/06
Filed: 1989-03-21
Abstract: A high capacity metropolitan area network (MAN) is described. Data 
traffic from users is connected to data concentrators at the edge of the network, 
and is transmitted over fiber optic data links to a hub where the data is switched. 
The hub includes a plurality of data switching modules, each having a control 
means, and each connected to a distributed control space division switch. 
Advantageously, the data switching modules, whose inputs are connected to the 
concentrators, perform all checking and routing functions, while the 1024x1024 
maximum size space division switch, whose outputs are connected to the 
concentrators, provides a large fan-out distribution network for reaching many 
concentrators from each data switching module. Distributed control of the space 
division switch permits several million connection and disconnection actions to be 
performed each second, while the pipelined and parallel operation within the 
control means permits each of the 256 switching modules to process at least 
50,000 transactions per second. The data switching modules chain groups of 
incoming packets destined for a common outlet of the space division switch so 
that only one connection in that switch is required for transmitting each group of 
chained packets from a data switching module to a concentrator. MAN provides 
security features including a port identification supplied by the data concentrators, 
and a check that each packet is from an authorized source user, transmitting on a 
port associated with that user, to an authorized destination user that is in the same 
group (virtual network) as the source user.

Filed: 1989-11-22
Abstract: The invention provides a heat-bonding blade (2) and a heat-bonding apparatus capable of heat-bonding thermoplastic resin sheets, in particular non-woven cloth sheets of thermoplastic resin, with or without heat-cutting these sheets. A first-type heat-bonding blade intended for heat-cutting/bonding has pressing members (3) provided on both sides of the blade. The distance (1) between the lower end of each pressing member and the edge of the blade is determined such that the pressing members lightly press the sheets of the thermoplastic resins when the edge of the blade has pressed into the sheets. A second-type heat-bonding blade intended only for heat-bonding the sheets is provided with a contact surface on the edge thereof. The contact surface is embossed (2b) so as to have a multiplicity of emboss projections (2a). This type of heat-bonding blade maybe formed by removing the pressing members from the blade of the first type and providing an embossed contact surface on the edge of the same. The heat-bonding apparatus of the invention employs one of these types of heat-bonding blade of the invention.

Title: Single data stream architecture for presentation, revision and resource document types
IPC: G06F13/00
Filed: 1989-04-25
Abstract: Electronic creation, modification and presentation of 
composed documents containing mixed document type 
characteristics is specifiable in a single data stream 
definition. This eliminates the proliferation of different 
architecture protocols that describe the various states of a 
document and reflects the natural condition of a composed 
document with some sections being in revisable state while 
other document sections are completed and therefore suitable 
for presentation. In addition, this data stream definition 
functions in an interchange environment and is therefore "self-­
contained" and capable of containing all the resources (e.g., 
fonts for text data, etc.) required for complete document 
composition fidelity.
