Title: Verfahren zur durchführung eines blind handover bei intersystem- und interfrequenz handover bei mobilkommunikationssystemen
Inventor: BRUECKEN REINHOLD
IPC: G01S5/00
Filed: 2003-06-25
Abstract: Die Erfindung betrifft ein Verfahren zur Durchfürung eines sogenannten „Blind Handover' bei einem Intersystem- und Interfrequenz Handover in Mobilkommunikationssystemen und geht davon aus, dass eine Mobilstation vor dem Handover von mehreren Basisstation versorgt wird, d.h. neben der versorgenden Basisstation auch Signale von mehreren anderen Basisstation empfangen kann. Erfindungsgemäss wird von der Mobilstation eine Laufzeitmessung der von den Basisstationen auf der Luftschnittstelle empfangenen Signale durchgeführt. Die gemessenen Laufzeiten werden an eine der Basisstationen übermittelt. Daraufhin wird seitens des Mobilkommunikationsnetzes anhand der übermittelten Laufzeitmessdaten der Aufenthaltsort der Mobilstation ermittelt. Mit Hilfe einer Datenbasis wird dann anhand des ermittelten Aufenthaltsorts mindestens eine geeignete Basisstation für einen Intersystem- oder Interfrequenz Handover ausgewählt, und die für einen Handover benötigten Daten der ausgewählten Basisstation an die Mobilstation übermittelt. Anhand dieser Informationen kann die Mobilstation den Handover zur ausgewahlten Basisstation durchführen.

Title: Grafting vinyl monomers onto polyester - fibres to improve dyeability
Inventor: HAPPE WILHELM DR
IPC: D06M14/32
Filed: 1969-12-27
Abstract: The dye-affinity of fibres of linear polyesters is improved by first treating the polyester fibres with methylene chloride and/or perchlorethylene and then graft polymerising with 2-vinylpyridine, 4-vinyl-pyridine and/or N-vinylimidazole under the influence of ionising radiation.

Title: Twin axle suspension for construction vehicle - has stabilised leaf spring on driven axle and linked struts for trailing axle
Inventor: SCARPATETTI DIETHER V DIPL ING
IPC: B60G5/047
Filed: 1974-04-09
Abstract: The front omnibus of the twin system for a construction vehicle or omnibus is driven while the rear axle is a trailing type. In order to improve the adhesion of the drive axle during acceleration the axle is braced in upper and lower arms, with one of the arms formed by the front section of a leaf spring assembly. The rear end of the leaf spring assembly is linked to a yoke, the other end of which supports the trailing axle. During acceleration the reaction forces on the leaf spring force the trailing end of the leaf spring down and hence lift the trailing axle slightly. This transfers some of the loading onto the driven axle. Over uneven ground the grip of the driven axle is ensured.
