The monitoring of complex or spacious buildings or spaces requires a multiplicity of monitoring devices, for example monitoring cameras, in order to be able to extensively cover such monitoring areas. For this purpose, the invention proposes a terminalhaving at least one functional device, wherein the functional device is in the form of a sensor and/or actuator device, having a control device, wherein the control deviceis in the form of a digital data processing device, and having at least one network interface, wherein the network interfaceis designed to couple the control deviceto a network, with the result that data can be transmitted from the functional device to the networkand/or data can be transmitted from the networkto the functional device. The terminalhas a client address from a first networkas the network, and the terminalhas a storage devicewhich stores a server address from a different network. The control deviceis designed to send a message to the server address via the network interfaceupon initialization of the terminal

A method is provided for diagnosing the operability of fuel vapor intermediate stores (), in particular of activated carbon filters, in tank-venting systems with at least one tank () and at least one fuel vapor intermediate store (). In this case an actual change degree of filling of the fuel vapor intermediate store () is determined as a consequence of absorption or desorption processes of gaseous hydrocarbons in the fuel vapor intermediate store (). The actual change in degree of filling is compared with a desired change in degree of filling and, from the comparison, a conclusion about the operability of the fuel vapor intermediate store () is drawn.

In a method and a device for operating an injection device () for an internal combustion engine, the injection device () includes injection valves (), via which fuel is injected directly into combustion chambers () of the internal combustion engine. Mechanisms are provided for detecting misfirings (), and for determining a fuel pressure (). A mechanical fault of an injection valve () is detected when a misfire occurs in a cylinder () and the fuel pressure simultaneously drops below a threshold value (SW). An electrical fault in an injection device () is detected when misfirings of cylinders () assigned to an output stage bank of the injection device () are observed, and the fuel pressure has dropped below a threshold value (SW). The responses to the faults that are implemented differ depending on the faults that were detected.

In a procedure for the functional diagnosis of an activateable fuel tank ventilation valve of the fuel tank system of an internal combustion engine, especially of a motor vehicle, whereby in specifiable time intervals when the fuel tank ventilation valve is activated to open, regeneration gas is added to the air drawn into the combustion chamber, whereby fuel is delivered to the combustion chamber, whereby the fuel, the air, respectively the fuel, the air and the regeneration gas are combusted in the combustion chamber and whereby by comparison of at least one operating parameter, which characterizes the combustion of fuel and intake air with the corresponding operating parameter, which characterizes the combustion of fuel, intake air and regeneration gas, inference can be made about the functional capability of the fuel tank ventilation valve, the HC-concentration of the regeneration gas is specifically affected by changing the regeneration gas stream.

A procedure to diagnose a fuel tank ventilation system of a motor vehicle and a device to implement the procedure are proposed. The fuel tank ventilation system contains at least one first ventilation pathway discharging into the air intake area of the internal combustion engine downstream behind a supercharger as well as at least one second ventilation pathway discharging into the air intake area upstream in front of the supercharger. Provision is made for a diagnosis with at least two partial diagnoses, whereby the first partial diagnosis pertaining to the first ventilation pathway is implemented, if the intake manifold pressure in the discharge area of the first ventilation pathway is smaller than the fuel tank system pressure; and the second partial diagnosis pertaining to the second ventilation pathway is implemented, if the intake manifold pressure in the discharge area of the first ventilation pathway is greater than the fuel tank system pressure. An error signal is provided, if at least one of the partial diagnoses generates a partial error signal.

Disclosed is a simple, easy-to-produce, and reliable connection between a shaft of a gas exchange valve and an actuator. This connection is detachable and, as a result, can be connected and disconnected multiple times. It is also possible to dispose the coupling piece on the shaft of the gas exchange valve and provide circumferential grooves on the control element of the actuator.

In a method for determining the rotational speed of the crankshaft of an internal combustion engine having a sensor disk which is connected to a crankshaft of the internal combustion engine, the sensor disk having a marking via a system of alternating teeth and tooth spaces, and a first sensor assigned to the sensor disk generating an electrical signal which is able to assume at least two signal levels, one of the signal levels being assigned to a tooth and the other being assigned to a tooth space, the accuracy of the rotational speed determination is increased in that the rotational speed of the crankshaft is determined by the control unit from the angle between two markings divided by the time elapsed between the two markings; additional markings may be situated between the two markings and the number of markings which are situated between the two markings is a function of the rotational speed.

The present invention relates to a connection between a shaft end of a gas exchange valve of an internal combustion engine and a sleeve-shaped actuating element of a valve actuator, which is guided in an axially movable manner within a pressure region, which is able to be pressurized with a pressure medium, of the valve actuator and at least partially surrounds the shaft end. The present invention provides for the connection to be situated outside of the pressure region and in the region of an opening, which is formed on the side of the valve actuator away from the combustion chamber, and is, for example, coaxial to the shaft end.
