摘要:
The invention relates to a central control unit (4) for a series of electronic apparatuses such as, for example, a CD player (1), a video recorder (2) or a satellite receiver (3). The electronic apparatuses are connected via a SCART cable to connections (5) of the central control unit (4). The central control unit (4) further comprises interfaces (6a, 6b) to mobile control apparatuses such as a PDA (8) or a PC (7), in which further external control apparatuses such as, for example, a mobile phone (9) can be connected via a network (12). The central control unit (4) translates protocols used for the connections (5) and the interfaces (6a, 6b) and thus provides the possibility of a flexible control of the electronic apparatuses (1, 2, 3).

A method and device for monitoring errors in an exhaust gas recirculation line, including supplying an engine with fresh air via a supply duct using a compressor, discharging exhaust gas via an exhaust duct using a gas turbine, a subflow of the gas being supplied from a low-pressure area of the exhaust duct downstream from the turbine, via the recirculation line, to an intake air low-pressure area of the supply duct upstream from the compressor, an exhaust gas mass flow of the subflow in the recirculation line is set via a valve, a fresh air mass flow being set by a fresh air throttle, or via an exhaust flap in the exhaust duct. Where the fresh air throttle or the exhaust flap is opened when the recirculation line is free of errors, an error in the recirculation line is deduced if the throttle or flap is at least partially closed.

A method for monitoring at least one part of an internal combustion engine based on a variable whose values characterize the operation of the part of the internal combustion engine during different states of the internal combustion engine, including: determining an actual pattern with the actual values of the variable during different states of the internal combustion engine which describe the actual operation of the internal combustion engine; providing a reference pattern for a known operation of the internal combustion engine, the reference pattern including reference values of the variable for different states of the internal combustion engine; and comparing the actual pattern to the reference pattern to determine a similarity between the actual operation and the known operation.

The invention relates to a wearable device arranged for enabling a bioelectrical interaction with an individual when being brought into contact with the individual's skin I, said device comprising electrodes 2 arranged to carry out said interaction by means of a first electrical signal, said electrodes comprise motion artifact detection means 4. The electrode assembly 1 comprises electrode 2 arranged to carry out a bioelectrical interaction with the individual by means of measuring an electrical signal on the body of the individual I and/or applying an electrical signal to the body of the individual. In order to enable said bioelectrical interaction the electrode 2 is provided with an electrical cable 2a. According to the invention, the electrode 2 is arranged with a pr 4. The pressure sensor 4 is arranged to measure a normal force component of an external force applied to the electrode due to movement of the individual. Preferably the pressure sensor 4 is a force/pressure sensitive resistor or a capacitive pressure sensor. The pressure sensor is arranged to produce an electrical signal, referred to as the second signal, the magnitude of the second signal being proportional to the pressure load. The pressure sensor 4 is arranged with cables 4a, 4b for purposes of signal proce

The invention relates to a system for determining user data, particularly user preferences or evaluations. The system comprises a multitude of mobile end apparatuses (1) which may be integrated in a portable apparatus such as a mobile phone or a watch (7) and are carried or worn by members of a group. The mobile end apparatuses (1) can establish a wireless communication with a central unit (2) and particularly transmit user data stored in a memory (4) or current user data detected via sensors (5). When using the system, for example, in a discotheque, the visitors favorite musical genres as well as an evaluation of the current program can be determined and taken into account. Via corresponding sensors (5), implicit evaluation criteria such as, for example, the movements of a user can be detected.

Theft protection of electronic apparatuses connected to a bus system is implemented in a manner particularly suitable for use in a digital home network based on the IEEE 1394 standard. At least one of the apparatuses in the network is equipped with a monitoring unit switchable between an activated and a de-activated state. In the activated state, the monitoring unit monitors the occurrence of a bus reset which is generated particularly upon removal of an apparatus from the network. After occurrence of such a reset, the monitoring unit compares the list of all apparatuses on the bus with a list generated and stored before the reset. When determining differences, an alarm is triggered which can be reproduced particularly by means of the apparatuses which are present, such as, for example, televisions and hi-fi equipment.

An interactive television application with watch lists is provided. The user may add programs such as television programs, Internet web pages, e-commerce applications, e-mail applications, and music channels, to a watch list. The user may also select a program from the watch list to watch it or to perform some other function related to that program. The interactive television application may display, under user control, watch lists that are overlaid over television programming, scaled so as not to obscure television programming, or on touch-screen remote controls. Programs may be added by the user to the watch lists at any time, or may be automatically added or removed by the interactive television application based on user preference profiles and reminder lists.

A device for error monitoring in an internal combustion engine system is provided. The internal combustion engine is supplied with air at a volumetric efficiency indicating the ratio of a real volume flow of air in the internal combustion engine to an ideal, theoretically possible, volume flow of air in the internal combustion engine. The device for error monitoring is configured to determine an error in the engine system when a difference between a measured volumetric efficiency and an estimated volumetric efficiency exceeds a predetermined absolute value.
