Abstract: Es wird ein Verfahren zur Wandlung der Zeilenzahl eines digitalisierten Fernsehsignals vorgeschlagen. Hierbei wird das Signal eines Teilbildes in einen ersten Speicher (1) in einer Richtung eingeschrieben und in einer dazu senkrechten Richtung ausgelesen, über ein Tiefpaßfilter (2) geleitet und in einen zweiten Speicher (3) in der letztgenannten Richtung eingeschrieben und in der erstgenannten Richtung ausgelesen. Durch die Teifpaßcharakteristik des Filters (2) wird eine Interpolation verschiedener Abtastwerte (Bildzeilen) bewirkt, so daß damit die Zahl der Abtastwerte (Bildzeilen) verändert werden kann.

Abstract: Vorrichtung zum Überbringen in anschlußbeinlosen Bauelementen, insbesondere von sogenannten Bauelemente-Chips, von einem Gurtband (7) auf eine vorgesehene Setzposition (29) einer Schaltungsplatine (31), wobei die Bauelemente (3) im Gurtband (7) festgelegt herangeführt werden. Zum Herausnehmen aus dem Gurtband (7) dient ein Drücker, der die Bauelemente einzeln gegen einen Saugaufnehmer (21) drückt. Das Bauelement wird zwischen synchron miteinander niederfahrendem Ausdrücker und Saugaufnehmer gegen ein Abreißen vom Saugaufnehmer gesichert, durch Richtwände eines Ausdrückkanals (53) hindurch in eine Schieberkammer (23) eingezogen. Der Schieber (25) fährt nach dem Aufnehmen des Bauelementes (3) in die Setzposition, aus der es eine Saugpipette (27) abhebt und später auf die Schaltungsplatine aufsetzt. Das Bauelement bleibt von dem Augenblick des Ubernehmens vom Gurtband bis zum Aufsetzen auf die Schaltungsplatine standig durch Unterdruck angesaugt. Dies wird dadurch bewirkt, daß in dem Schieber auch nach dem Zurückziehen des Saugaufnehmers ein Unterdruck erhalten bleibt, der das Bauelement beim Verfahren des Schiebers festhalt, bis die Saugpipette es wieder ansaugt. Das Bauelement wird mithin von der Übernahme vom Gurtband bis zum Aufsetzen auf die Setzposition niemals mehr frei. Dadurch wird das Ausrichten des Bauelementes wesentlich erleichtert. Eine erste Ausrichtung erfolgt im Ausdrückkanal, eine zweite Austrichtung in der Schieberkammer und schließlich in der Ausrichtkammer nach dem Herausheben aus der Schieberkammer in die Ausrichtkammer.

Patent EP-0080266-A2 (EP)
Inventor: ROSSITER TIMOTHY JOHN MILES
IPC: G06F17/14
Filed: 1982-10-21
Abstract: In a transmultiplexer, which is an interface between a number of PCM highways and an FDM group, the conversion between PCM and FDM involves first converting the PCM words into their linear form and filtering them, applying them to a circuit which performs a discrete Fourier transform (DFT) on them followed by a second stage of filtering. An efficient implementation of a DFT is described which reduces the number of multiplications required by making use of certain symmetry properties in a DFT matrix. 
     The whole can be used «backwards», as it were to give an inverse Fourier transform as needed for the FDM-PCM conversion.

Abstract: For increasing the life of a discharge lamp with heatable electrodes, adequate pre-heating must be provided before ignition of the lamp. In an inverter, the load circuit of which contains the discharge lamp (L) and a series resonant circuit (C23, L7) in a series circuit, adequate pre-heating is achieved according to the invention by temporarily increasing the operating frequency of the inverter. If the switch of the inverter is controlled by a transformer (T8), the primary winding of which is located in the load circuit, this object is achieved in particular by short-circuiting a small additional winding (L85). <IMAGE>
