Wolfgang Stripf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for fail-safe transmission, safety switching device and control unit
    Patent number: 8321774
    Abstract: A method for fail-safe transmission of information between a transmitter and a receiver is disclosed. At least two telegrams relating to the information are transmitted as a first telegram via a first channel and a second telegram via a second channel from the transmitter to the receiver. To identify an error affecting the information during transmission, a first identifier is generated from a first subset of the first telegram being used at the receiver to identify the information contained in the first telegram. This method is used for communication from a safety switching device to a control unit.

  • Microprocessor-controlled field device for connection to a field bus system
    Patent number: 7337369
    Abstract: A microprocessor-controlled standard field device, such as a measuring sensor or an actuator, is connected to a field bus system that, in turn, is connected to, for example, a freely programmable controller. The field device is equipped with a security layer for carrying out a security proven communication. A secure and simultaneously cost-effective communication with a control device via a field bus system is made possible by implementing a security layer in, e.g., a conventional operationally proven or redundant standard field device.

  • Microprocessor-controlled field device for connection to a field bus system
    Publication number: 20040128588
    Abstract: The invention relates to a microprocessor-controlled standard field device (3′, 4′, 5′, 6′), such as a measuring sensor or an actuator, for connecting to a field bus system (1) that, in turn, is connected to, for example, a freely programmable controller (2′). According to the invention, the field device (3′, 4′, 5′, 6′) is equipped with a security layer (10) for carrying out a security proven communication. A secure and simultaneously cost-effective communication with a control device (2) via a field bus system (1) is made possible by implementing a security layer (10) in a conventional operationally proven or redundant standard field device (3, 4, 5, 6).
