  • Patent number: 10166969
    Abstract: A method and apparatus for recuperating energy in a hybrid vehicle, having an internal combustion engine an electrical machine, and on-board electrical system with an energy store that can be charged with electrical energy during a recuperation operation. A recuperation power for a recuperation operation of the electrical machine is set to a first value that allows a recuperation operation with a maximum generator capacity of the electrical machine if an actual energy level of the energy store is lower than or equal to a threshold value. However, the recuperation power for a recuperation operation is set to a second value lower than the first value and allows a recuperation operation with a reduced generator capacity of the electrical machine if the actual energy level of the energy store is greater than the threshold value.

  • Patent number: 8086325
    Abstract: The invention relates to a process control system comprising a calculating unit enabling a charge value (W) to be determined from operations occurring in the process control system. Preferably, said process control system comprises a process control computer with a web server and a computer which is used to access the processes control computer via Internet. The charging value (W) is especially a service fee which is to be paid to an application service provider by a user of the process control system.

  • Patent number: 7703093
    Abstract: A method is disclosed for a system including at least one process management computer and a number of field devices, whereby status and control signals are transmitted between at least some of the field devices and the process management computer using a TCP/IP protocol over a communication channel, preferably a radio connection and/or the Internet. A process management system includes a process management computer with a web-server, a client computer with an Internet browser and a number of sensors and actuators. The process management system may preferably be operated by way of the Internet, using the client computer.

  • Publication number: 20040249651
    Abstract: The invention relates to a method in which at least one process management computer (7) and a number of field devices (FD) are applied, whereby status and control signals are transmitted between at least some of the field devices and the process management computer using a TCP/IP protocol over a communication channel, preferably a radio connection (F) and/or the Internet (15). According to the invention, a process management system (5) comprises a process management computer (7) with a web-server (9), a client computer (20) with an internet browser (22) and a number of sensors (S) and actuators (A). The process management system (5) may preferably be operated by means of the internet (15), using the client computer (20).
