Abstract: For data analytics in magnetic resonance (MR) scanning, the scanning configuration information and the resulting raw data are directly used to determine the analytics or clinical decision. Artificial intelligence provides a value for a clinical finding characteristic of the patient based on the raw data from scanning and the controls used to scan, allowing the value to be based on all of the information content of the scan results. Reconstruction is not needed, allowing for simpler hardware, such as hardware with less homogeneous B0 and/or B1 fields than the norm and/or non-linear gradients.

IPC: H04Q3/00

Abstract: Method for supplying a call and line current without inductances, relay contacts or transformers to a two-wire subscriber line by means of a power-feeding unit (EE) which contains controlled current sources (S1a, S1b, S2a, S2b). During the ringing, the first current source (S1a) feeds a ringing current pulse sequence (IS) into the connected subscriber line (a). After the handset has been removed, this current source (S1a) feeds in the line current which can be modulated with information items. The ringing current disconnection is controlled by an instantaneous ringing pulse amplitude which occurs not during the initial settling processes immediately after the beginning of such a ringing pulse (IS) but only after these have decayed sufficiently. For this purpose, the ringing current pulses or clock pulses are supplied to a delay unit which, in turn, causes the sampling measurement of the relevant instantaneous amplitude in a measuring unit (ME) at the right time. The measuring unit then controls the power-feeding unit (EE) in dependence on the measured instantaneous amplitude (Figure 2). <IMAGE>

Abstract: Bisher wurden zur Helligkeitsverstärkung von passiven Anzeigevorrichtungen Fluoreszenzplatten relativ großer Dicke verwendet. In diesen Platten herrscht bei einer gegebenen Konzentration von Fluoreszenzstoffen wegen des großen Volumens relativ geringe Leuchtdichte. Damit ist auch die Helligkeit der Anzeige gering. Die Leuchtdichte läßt sich durch Verwendung von (dünnen) flexiblen fluoreszierenden Folien (1,4,5) steigern, da hier die Konzentration an Fluoreszenzstoffen umgekehrt proportional der Dicke erhöht werden kann. Durch die Flexibilität der Folien (1,4,5) werden außerdem die konstruktiven Gestaltungsmöglichkeiten erweitert. Die Erfindung wird zum Beispiel bei Flüssigkristallanzeigen angewendet.
