IPC: H04N7/18
Filed: 1986-09-11
Abstract: A scatter radiation compensation method for use in 
a medical diagnosis x-ray imaging system employs the 
use of an attenuating material (32) placed in an x-ray beam (12) 
to attenuate a portion of the beam such that the 
in-line component of the beam is reduced in the 
attenuated area. In one embodiment, an additional 
image is then taken utilizing an attenuator (34) through out 
the full area of the beam to provide an image 
indicative of in-line components of the x-ray beam. 
The difference in image intensity between the two 
images is then computed to determine the scatter 
component of intensity and that intensity is thereafter 
subtracted from the overall intensity obtained in a 
medical diagnostic image to obtain an image with the 
scattering effects removed. In one embodiment, the 
attenuating objects are plural spaced objects (32) located 
at predetermined positions in the image. In a further 
embodiment, the image is taken through an attenuating 
object (34) covering the entire beam, the object having a 
plurality of holes located at spaced intervals for 
permitting a portion of the beam to pass through 
unattenuated. In either embodiment, the component of 
scattering is determined by comparing the relative 
intensity values between the images developed with an 
object passing a portion of the beam unattenuated and 
an object passing an attenuated beam.

Filed: 1987-01-31
Abstract: Bei der Satellitenübertragung von Fernsehsignalen wird 
dem zu übertragenden Signal vor der Frequenzmodulation ein 
sog. Verwischungssignal überlagert. Dieses Verwischungssi­
gnal verursacht im Satelliten-Fernsehempfänger uner­
wünschte Helligkeitsänderungen und Störungen bei der Syn­
chronisierung. Diese werden nach der vorliegenden Erfindung 
vermieden, indem aus den Synchronsignalspitzen des demo­
dulierten Satelliten-Fernsehsignals eine analoge Regelspan­
nung gewonnen und dem störbehafteten Signal hinzuaddiert 
wird. Die Abtastung der Synchronsignalspitzen erfolgt in 
einem Zeitintervall, dessen Dauer höchstens gleich der Dauer 
der Vor- bzw. Nachtrabanten des Videosignals ist. Damit kön­
nen auch während der vertikalen Austastlücke korrekte, die 
Amplitude des Verwischungssignals kennzeichnende Abtast­
werte gewonnen werden.

Title: Connection fitting made of two parts
IPC: E05D7/04
Filed: 1987-11-23
Abstract: In a two-part connecting fixture for connecting parts of a piece of furniture, preferably to a hinge bracket and mounting plate assembly, one of the parts of the fixture is provided with a spring-loaded pivoted lever and the other with an abutment that is interengageable with the lever. The lever and the abutment are respectively provided on confronting surfaces with a beveled or rounded detent flank and with an engaging edge. The lever is arranged to snap to its locking position as the parts are fitted together and are displaced or pivotally moved to a connecting position. The lever is adapted to be released from its locking position by an actuating mechanism. A stop is provided, which during or after the snapping of the lever to its locking position limits the displacement of the parts which are interlocked. A safety mechanism is provided for preventing an unintended release of the interlocked parts. The detent flank is formed with a locking portion consisting of an aperture, recess, notch or step at the beginning of that region of the detent flank which is swept by the engaging edge as the detent lever moves to the locking position. The engaging edge interengages with said locking portion as the detent lever moves toward its release position.

IPC: H03K17/04
Filed: 1989-07-04
Abstract: In der digitalen Schaltungstechnik werden bipolare Tran­
sistoren wegen ihrer großen Steilheit vorteilhhaft für 
Schaltvorgänge eingesetzt. Da ein in Sättigung betriebener 
Transistor (3) ein verlangsamtes Schaltverhalten aufweist, muß 
bei schnellen Schaltvorgängen die Sättigung vermieden 
werden.  
     Bei Schottky-Dioden wird die Sättigung dadurch vermieden, 
daß parallel zur Basis-Kollektor-Sperrschicht eine Schottky-­
Diode geschaltet wird.  
     Allerdings erfordert die Herstellung von Schottky-Dioden in 
der integrierten Schaltungstechnik zusätzliche Prozeß­
schritte.  
     Die erfindungsgemäße Schaltung vermeidet diese zusätzlichen 
Prozeßschritte, indem sie die Schottky-Diode durch ein 
unidirektionales Halbleiterelement ersetzt, das aus Feld­
effekttransistoren (1, 2) zusammengestzt ist.  
     Für die Herstellung der Schaltung eignen sich besonders die 
Verfahren der BICMOS-Technologie, die die monolithische 
Integration von Bipolar- und MOS-Transistoren ermöglichen.

Abstract: Methods and apparatus are set forth for utilizing 
the restricted token operation on an FDDI network. Two 
service primitives are defined to facilitate the control of 
restricted dialog. The first defines what class of token 
can be captured for the purpose of transmitting asynchronous 
data. Secondly, a primitive is defined for use at the end 
of each transmit request to give control over the token type 
that will be issued at the end of a given transmission. A 
hardware protocol is defined which provides reliable control 
over these two parameters, together with methodology for 
linking frames in a buffer memory during restricted 
operation. The combination of the hardware protocol and 
methodology allows restricted dialog to be realized without 
real-time software interaction.
