Abstract: A valve cage for guiding an actuator, such as a stroke piston, may be used in a control valve for adjusting a process fluid flow (e.g., a water flow) in a process plant (e.g., a food processing plant, a brewery, etc.) The control valve may include a sensor for detecting a chemical and/or biological property of the process fluid, and at least one analyzer for the process fluid that is arranged on the valve cage such that the analyzer can interact with process fluid.

Abstract: In a method for the encryption communication in a process plant, one or more keys for coding of electronic signals regarding the process plant, such as actuation signals, measurement signals, state signals, warning signals or such, are provided. The one or more keys are transmitted as acoustic signal via a ductwork guiding plant fluid, particularly a process fluid or an auxiliary fluid, from the first communication partner to the second communication partner. The process plant can be a chemical plant, a power plant, or a food-processing plant. The communication can be between a first and a second communication partner, which can include at least one field device, such as an actuator for adjusting a process fluid and/or a control electronics for supervising, controlling and/or regulating processes of the process plant.

Abstract: In a method for optimizing a modular system for technical functional units of a process engineering plant, a modular system is provided having components for configuring technical functional units. The modular system can be projected in a simulation environment such that each component can be represented based on its physical properties as a virtual component with corresponding parameters in the simulation environment. Parameters of the virtual components are varied in the simulation environment to determine a modified configuration of at least one technical functional unit using at least one of the virtual components with at least one varied parameter. The operation of the technical functional unit(s) is simulated with the modified configuration. A set of virtual components is determined from the virtual components with varied parameters based on results of the simulation. One or more components of the modular system are adapted based on the determined set of virtual components.

Abstract: A diagnostic system and method to function-monitor an actuator to affect a process medium stream of a process engineering plant can include an optical microphone allocated to the actuator and a diagnostic electronics. The optical microphone can be configured to measure an acoustic, actuator-specific operating signal, as leakage sound and cavitation sound, based on electromagnetic radiation that is affected by the acoustic, actuator-specific operating signal, and generate an electrical measuring signal based on the measured acoustic, actuator-specific operating signal. The diagnostic electronics can be configured to receive and store, process, and/or transmit the electrical measuring signal.

Abstract: A device installed in a vehicle for recording information on the itinerary of the vehicle. The device includes a receiver system for receiving wirelessly transmitted information for identifying the current geographical position of the vehicle, a computer unit for computing digitalized data on the geographical position of the vehicle, and a memory unit for continuous storage of the digitalized geographical position data of the vehicle on a data carrier, which is protected against overwriting of recorded data, whereby the memory device also stores time data, which allow identification of the particular point in time at which a particular vehicle position was found. So that an itinerary taken by a vehicle can later be reconstructed without great expense the data carrier is configured to be easily exchangeable, and a data reading device is provided for the input of data that identify the driver of the vehicle and are recorded on the data carrier.

Abstract: The invention is directed to an optoelectronic imaging system for industrial applications having at least two optical lenses (1, 2) which are spaced apart from one another and an electronic image sensor (8), wherein the imaging sharpness on the image sensor (8) and the imaging scale (zoom) are mechanically adjustable by means of a control unit.

Abstract: A use billing system with an arrangement for identifying distances traveled by a moving object within a system of traveled distances or for identifying fixed geographical zones entered by the object. In order to provide a billing arrangement which is universally applicable as far as possible and which requires little expenditure on infrastructure, a system is provided which is installed independently for wireless transmission of information to detect the current geographical position of the object. The moving object carries a reception system to receive the information transmitted over the air and a storage device for temporary storage of data. A second storage device for permanent storage of predetermined data is also carried. The object further carries a comparison device for comparing these data. An identification device is carried by the object for identifying the respective traveled distance.
