  • Publication number: 20220002180
    Abstract: A method for producing a glass product, preferably a sheet-like glass product, is provided that includes conveying a molten silicate glass through a conduit system from one area of a glass product producing installation to another area of the glass product producing installation. The conduit system includes noble metal and is configured to conduct an electric current through the noble metal so as to generates Joule heat in the conduit system. The current is an alternating current for which the time integral over a positive and a negative half-wave results in a zero value.

  • Patent number: 11178472
    Abstract: A PON system comprising multiple PONs, each having a respective intelligent splitter monitor (ISM). In addition to having a passive optical splitter therein, an ISM also has several remotely powered active components configured to monitor the presence of uplink light signals on the ports of the splitter and communicate with the central office using out-of-band optical signals. These ISM functionalities enable the network operator, e.g., to automatically map PON connectivity, pairing each port on the splitter with a distinct optical network unit. The PON system further comprises an optical module connected to the multiple PONs through an optical switch in a manner that supports shared access to said module by the corresponding multiple ISMs. In an example embodiment, the optical module comprises an optical transceiver capable of communicating with the ISM transceivers and one or more lasers configured to provide high-intensity light for remotely charging the ISM batteries.

  • Patent number: 11150060
    Abstract: A base body for a metal-sealing material-feedthrough subject to high pressures in an igniter for an airbag or a belt tensioning device. The base body for the metal-sealing material feedthrough is an element formed by a process of cold forming and having a ring-shape or a plate-like shape. The element includes a feedthrough opening extending from a front side of the element towards a rear side of the element. There is a metallurgic section in the element of the base body with structure-lines or flow-lines that are bent due to a reshaping process of the process of cold-forming.

  • Publication number: 20210236081
    Abstract: A computer-implemented method is for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during image acquisition using an x-ray emitter and an x-ray detector. A first image data of a first preparatory image is evaluated to determine if a repeat condition is fulfilled and/or to determine the main acquisition parameter and/or at least one second preparatory acquisition parameter. The first preparatory image is acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter. In all cases or when the repeat condition is fulfilled, the main acquisition parameter is determined depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while at least one second preparatory acquisition parameter is used to control the x-ray emitter.

  • Publication number: 20200378249
    Abstract: Systems and methods for identifying a likelihood that a reservoir of a geological formation received a secondary charge of hydrocarbons of relatively very different thermal maturity of composition are provided. One method includes positioning a downhole acquisition tool in a wellbore in a geological formation and testing one or more fluid properties of the formation fluid. Data processing circuitry may identify whether a relationship of the one or more fluid properties exceeds a first threshold that indicates likely asphaltene instability. When this is the case, data processing circuitry may be used to model the geological formation using a realization scenario in which multiple charges of hydrocarbons of substantially different thermal maturity or substantially different composition, or both, filled a reservoir of the geological formation over geologic time.
