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).
摘要:
A method for checking a function of an actuator or a sensor of a system, having the following steps: controlling the actuator within a time window if at least one state variable of the system is in a predefined operating range; detecting a system response, with the aid of the sensor, within the time window as a response to controlling the actuator; determining a malfunction of the actuator or of the sensor if the system response differs from a setpoint system response that is expected due to controlling the actuator. A further actuator of the system is controlled during the time window in such a way that the at least one state variable of the system remains in the predefined operating range during the time window. Moreover, a corresponding method for calibrating a sensor or an actuator of a system is described.

A device to carry out a bioelectrical interaction with an individual by means of electrodes 29, 29a whereby an on-demand verification of the integrity of the electrical contact of the electrodes is implemented. The device 20 comprises a control unit 22 arranged to determine an occurrence of the predefined event related to a quality of a measured signal. In case the predetermined event is detected, the control unit 22 actuates the testing means 24. The testing means is arranged to generate the test signals, I1, 12 and to apply them via a coupling circuit 23, 23a to the electrodes. In case it is desired that cumulative information about the contact integrity is obtained, is it sufficient to apply a single test signal per electrode. In case it is required to determine which of the electrodes has lost its contact, a sequence of test signals is generated by the sequencer 24b. The response signal from the electrodes 29, 29a is forwarded to the input filter 26, which is preferably also used for a normal signal analysis. The signal from the input filter 26 is directed via the input impedance 25, 25a to the input amplifier 28. The amplified response signal is forwarded to the signal processing means 30 which is arranged to analyze the response signal. Preferably, an amplitude analysis is done. The signal from the signal processing means 30 is supplied to the analog-to-digital converter (ADC) 32 after which a digital processing of the response signal is carried out by means of a further processing unit 34. In case the further processing unit 34 determines that the integrity of the contact is below the allowable level, the lead-off indicator 36 is actuated.

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 the 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 pressure sensor 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 processing.

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.

摘要:
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.

The system (1) according to the invention is arranged to support an automatic informing of callers (S1, S2, . . . , SN) upon an event of an interrupt in a telecommunication line engaged with a receiving station (4) according to a telecommunication protocol. In order to carry out said automatic informing the receiving station (4) is adapted with a computer program (6,8,10,12,14) arranged to transmit a prerecorded message to all engaged parties upon an event of the interrupt. The computer program is further arranged to carry out background interaction with a caller who is put on hold, so that the caller is not left behind unattended.
