Title: Wind sieve with centrifugal action
IPC: B07B7/00
Filed: 1991-02-08
Abstract: A pneumatic centrifugal separator comprises guide vanes disposed along the generatrices of a fictitious cylinder having a vertical axis, the guide vanes being adapted to impart to a gas stream entering the fictitious cylinder a rotary motion about the vertical cylinder axis, and a rotor coaxially positioned in the interior of the fictitious cylinder, the rotor being equipped with a first set of vertical blades distributed uniformly along the periphery of the fictitious cylinder and a second set of blades disposed between the blades of the first set and the cylinder axis. A gas stream and particulate material to be sorted is introduced between the guide vanes and the rotor, and the gas stream charged with particles of dimensions smaller than predetermined dimensions and sorted out of the particulate material is drawn out of a central outlet. The second set of blades is arranged to guide the streams of gas coming through channels between adjacent vertical blades of the first set to the central outlet.

IPC: G06F3/0484
Filed: 1996-09-05
Abstract: A system and method for providing annotation overlays from diverse 
sources of commentary for World-Wide Web documents is disclosed. 
Sources of commentary contribute annotation overlays regarding particular 
documents on the World-Wide Web. The annotation overlays from a 
particular source are stored on one or more overlay servers, which are 
connected to the Web. A user of a Web browser opens an annotation proxy 
server between the Web browser and the Web servers that intercepts all 
documents retrieved by the Web browser and merges with the retrieved 
documents commentary from sources designated by the user of the Web 
browser that refer to the requested documents. Multiple annotation overlay 
proxies can be serially connected. The annotation proxy can perform the 
merge oration by first creating a local annotation directory of annotation 
overlays from sources designated by the user then, when the user requests 
a document, merging with the requested document information only from the 
annotation directory. Alternatively, the annotation proxy can perform the 
merge operation on the fly by pulling the annotation overlays directly from 
the Web servers without the use of a local annotation directory.

Title: Full optical type optical element
Inventor: HIRAGA TAKASHI
IPC: G02F1/17
Filed: 1996-12-05
Abstract: A full optical type optical element performs an
information processing on an input signal light beam (1)
through use of only light beams including the signal light
beam (1) and an auxiliary light beam (2) for assisting
operation. The optical element includes aggregates (3)
which are dispersed within the optical element as optical
functional aggregates, and which are composed of a single
kind or multiple kinds of compounds including a single
species of atoms or molecules. Thus, a full optical type
optical element having a high resolution can be obtained
through use of a thin-film element which contains
nanoparticles comprising molecules of an organic compound
and associates/aggregates of these molecules.

Inventor: KOMATSU KEIRO
IPC: H04J14/02
Filed: 1996-12-27
Abstract: A light wavelength filtering circuit in a wavelength-division
multiplexing light communication system minimizes transmission loss in
the waveguide after wavelength discrimination by having a linear output
waveguide added to an output end of a light wavelength discriminating
element, at which a signal having a long wavelength is outputted. A
curved output waveguide is added to the rear stage of the output end at
which a signal having a relatively short wavelength is outputted. Hence, a
radiation loss at the output waveguide at the output end is minimized,
while a space between the output light waveguides is being widened.
Additionally, a core layer bandgap wavelength at the output waveguide of
the long wavelength signal is set to be longer than a core layer band gap
wavelength in another region. Hence, a substantial light confinement is
formed in a horizontal direction even in the output waveguide at the long
wavelength signal side and even if the output waveguide at the long
wavelength signal side is curved, and the radiation loss can be reduced.

IPC: G07C9/00

Abstract: A system and method are provided for producing verified signatures
on documents such as checks and affidavits. Initially, a customer who is
to obtain a verified signature, at some point in time, registers with a
signatory authority, and a secret key, having public and private
components, is established uniquely for that customer. When a document
requires a verified signature, the customer presents the document and
proof of his/her identity, such as a preprogrammed computer-interfacable
card, to a signature system. Typically, such a system is to be available
at an institution, such as an office, bank, or post office, where such
services will routinely be used. The system accesses the archive of the
private portion of the customer's key, and generates an encoded signature
based, in part, on the content of the document. Accordingly, when a
recipient of the document later wishes to verify the signature, the
recipient uses the customer's public key to decode the signature. It is
then straightforward to verify the signature against the content of the
document.

Title: Verfahren und Schaltungsanordnung zum Trennen von Luminanz- und Chrominanzsignalen eines FBAS-Signals
IPC: H04N9/78
Filed: 1997-02-27
Abstract: Bei analogen Farbfernseh-Übertragungsverfahren besteht das 
übertragene FBAS-Signal aus Luminanz- und Chrominanz-Signalen, 
die in einem Fernsehempfänger voneinander getrennt 
werden müssen, um eine separate Weiterverarbeitung zu 
ermöglichen. Hierfür können Kammfilter eingesetzt werden, 
wobei häufig mit einer bildinhaltsabhängigen Steuerung 
gearbeitet wird, die in Abhängigkeit von den jeweiligen 
Chrominanzsignalen zwischen verschiedenen Filteralgorithmen, 
d.h. verschiedenen Zeilenverknüpfungen, umschaltet. Bei 
herkömmlichen Kammfiltern wird das FBAS-Signal in das 
Luminanzsignal und ein noch in die beiden 
Farbdifferenzsignale zu demodulierendes Chrominanzsignal 
aufgespalten. Hierbei erfolgt insbesondere das Erkennen von 
Farbkanten nicht immer fehlerfrei. Dieses kann zu einer nur 
unvollständigen Trennung der Luminanz- und Chrominanzsignale 
führen, so daß Cross-Effekte nicht völlig vermieden werden 
können. Eine bessere Detektion von Farbkanten und damit eine 
verbesserte Trennung der Luminanz- und Chrominanzsignale 
kann erreicht werden, wenn zur Auswahl des Filteralgorithmus 
auch die Struktur des Luminanzsignales untersucht wird. 
Erfindungsgemäß werden daher aus dem FBAS-Signal zwei 
Farbkomponentensignale (U*, V*) demoduliert, die zusammen 
mit dem FBAS-Signal zur Bestimmung einer optimalen 
Zeilenverknüpfung (CF2) ausgewertet werden und entsprechend 
dieser Verknüpfung eine verbesserte Generierung des 
Luminanzsignales (Y) und der Farbdifferenzsignale (U, V) 
ermöglichen.

Abstract: Novel means of achieving increased security while still obtaining a
low cost, manufacturable device are disclosed and claimed. The
first mode of operation is the learn mode which provides means for
initial checkout with no security. In the learn mode of operation,
the interrogator and transponder may be switched to a predetermined
error detection algorithm, i.e. CCITT(Start Mask 46, CCITT Mask
42), and certain information is programmed into the transponder
memory. During programming, all the bits received from the
interrogator are shifted through the preintialized CRC generator.
In addition, once the transponder response is sent back to the
interrogator, the response is also shifted through a preinitialized
CRC generator within the interrogator(which could be a software
implementation). Because neither the Cypher Key 58 nor the
Function Key 56 are directly readable once programmed, an
encryption must be performed to verify the proper Cypher Key 58 and
Function Key 56 were programmed into the transponder's memory. In
the second and encryption mode of operation, after a special
Command/Address is transmitted, a Random Number (which may vary in
length but which has a minimum length) is transmitted from the
interrogator to the transponder which in turn generates the
Signature by shifting the Random Number through the CRC Encryption
Generator (initialized with the Cypher 58 and Function Key 56).
The Signature along with data, status and address are transmitted
back to the interrogator which in the meantime has predetermined
the awaited Signature using the same Cypher 58 and Function Key 56. 
     If the received Signature and calculated Signature are equal,
validation is positive and then the programmed data must be
locked(especially the Cypher Key 58 and Function Key 56) to protect
them against reprogramming in the future
