Title: Elektrochirurgischer generator mit verbesserter invertersteuerung und entsprechendes verfahren
Inventor: JANICH FABIAN
IPC: A61B18/12
Filed: 2023-06-28
Abstract: Elektrochirurgischer Generator und Verfahren zur Ausgabe einer hochfrequenten Wechselspannung an ein elektrochirurgisches Instrument (16), mit einem Inverter (3), der eine hochfrequente Wechselspannung variabler Frequenz und Amplitude erzeugt, die einer Ausgangsbuchse (14) für das elektrochirurgische Instrument (16) zugeführt wird. Erfindungsgemäß handelt es sich bei dem Inverter um einen Multilevel-Inverter (3), der durch ein Referenzsignal gesteuert wird, das die Form der erzeugten HF-Wechselspannung definiert, wobei das Referenzsignal durch ein Datagramm (100, 200) definiert ist, das eine endliche Reihe von aufeinanderfolgenden Amplituden- und Frequenzdatenvektoren für eine definierte Anzahl von Perioden umfasst. Durch solche Datagramme, die beschreibende Daten für die gewünschte HF-Sinuskurve enthalten, können die benötigte Datenmenge und Bandbreite reduziert werden. So lassen sich mit einem Minimum an Daten, das so gering sein kann, dass es lediglich einige Dutzend Bytes lang ist, eine Vielzahl von Modi beschreiben. Dies ermöglicht eine effiziente Steuerung auch komplexer Moden.

IPC: H01L21/033
Filed: 1980-02-28
Abstract: A method is disclosed for fabricating structures having electrically conductive regions such as high resolution semiconductor device and circuit designs which require only low resolution alignment steps during fabrication. The method is used to fabricate metal semiconductor field effect transistors (MESFET) and metal oxide semiconductor field effect transistors (MOSFET) devices and incorporates the following features. A device with very small (i.e. sub- micro-meter) dimensions is positioned in a relatively large device well such that the exact position of the device in its well is not critical. Isolation and interconnection of devices in different wells is achieved by standard masking and alignment techniques with a resolution corresponding to the larger dimensions of the device wells. All high resolution features of each device are contained in a single masking level (26). To separate and insulate different elements of the device at such small dimensions different height levels are used in the device so that one masking step can produce zero lateral spacing between the different device elements (32). The disclosure provides examples of the present method applied to the fabrication of a MESFET device and a MOSFET device and to isolation and interconnection of single devices into large circuits on a semiconductor chip.

IPC: H04B3/02

Abstract: A signalling apparatus has at least one transmitter in a transmitter assembly for transmitting a signal by impressed current to several spatially separated receivers. A series circuit of threshold members is connected to the output terminals of each transmitter, the number of members corresponding to the number of receivers. The input of each receiver is connected to a threshold member; the receivers are therefore connected in series on the input side. It is ensured thereby that the same current flows through all receivers. In the event of a failure of a transmission line or a receiver, the current continues to flow through the associated threshold member so that signal transmission to the other receivers continues uninterrupted.
