  • Patent number: 11558261
    Abstract: A network device (100) detects a network problem in a medical system (105). A reception module (110) receives current medical system process data. A monitoring module (120) detects predefined events (124) based on the process data and triggers a detection signal (132) output in the presence of a predefined event. A sending module (130) sends the detection signal to a predefined device address (134) via a network (140). The predefined events include: a predefined plurality of unsuccessful password entry attempts within a predefined first time period; an unsuccessful encryption within an encryption protocol framework; a predefined plurality of outputs via the network triggered via the network within a predefined second time period; an output of a signal, which is to be carried out, has been unsuccessful; and a predefined number of messages have been received within the framework of a service discovery within a predefined third time period.

    Abstract: A control system (100) for a device (105) for making possible a process control for a process carried out on the device, with a reception module (110) and with a processing module (120). The reception module is configured to receive process information (112). The process information pertains to currently carried out process steps (114) of the process. The processing module is configured to assign a sequence number (122) to the received process information and to generate a visible protocol signature (128) based on the sequence number, of the process information, of time information (124) and a secret system code (126) and to assign it to the process information, and to output the process information with the assigned visible protocol signature. The secret system code is stored n this case exclusively in an internal memory (125) of the control system.

  • Patent number: 5381789
    Abstract: An ionizer for the ionization of oxygen during any type of oxygen therapy. The ionizer contains an ionizing unit inside a housing. The housing has a grounded contact safety screen mounted thereon by means of a conducting metal ring and a high-ohmic resistor. A glass flask is mounted or screwed onto the housing to serve as a connection between the face mask and the ionizer. The housing has a projecting socket enclosed in a conducting metal cylinder connected to the high-ohmic resistor. The ionizing unit includes ionizing needles located directly adjacent the contact safety screen. Sufficient ionization of oxygen occurs without the production of ozone.

  • Patent number: 4900777
    Abstract: Aqueous copolymer dispersions suitable for use in the manufacture of adhesives or as binding agents or as coating substances are produced by the emulsion polymerization of from 1 to 50% by weight of ethylene and from 99 to 50% by weight of vinyl monomers. With the process of the invention, in which, as vinyl monomers, vinyl chloride and, if desired, other ethylenically-unsaturated monomers, for example esters, are used, a higher ethylene content in the copolymer can be obtained at a lower pressure than hitherto. For this purpose, the greater part of the vinyl monomers is metered in and, in addition, an inert organic substance is used.
