The invention relates to the technical field of local data transmission networks, in particular domestic networks. In networks such as these, the network stations log on in connection to the network. On disconnection, the network station which is leaving the network logs off in an appropriate manner. In the situation in which the user disconnects a network station simply by pulling out the network cable from the network, it is physically impossible to transmit the logging-off message. The invention is now concerned with the problem of how reliably an inactive network station can be identified, also taking account of the disconnection of the network station simply by pulling out the network plug. The invention solves the problem by regular transmission of a search request to the stations in the network. If a search request remains unanswered by one network station, an HTTP access is additionally attempted to, for example, the device description of the network station in question, or a control request. The network station is identified as being inactive only if this access/control request also fails. In the case of a UPnP network, the search request is made using the unprotected SSDP protocol, so that the lack of any response to the search request does not in its own right reliably indicate that the network station has logged off. The supposition that the network station which did not respond to the search request is inactive is confirmed by means of the HTTP access, which takes place on an error-protected basis.

In a reading device for reading storage films, a reading light beam rotating about an axis of rotation is directed onto the storage film through a reading opening of a film support. Fluorescent light returning from the storage film falls through the reading opening into a photodetector. Misreadings produced by reflected secondary reading light are reduced by the provision of a filter at the reading opening, which filter allows at least some fluorescent light to pass and attenuates reading light reflected from the storage film.

The invention relates to the technical field of home networks. A home network based on the present UPnP standard (Universal Plug and Play) allows data to be interchanged between network subscriber stations. A UPnP standard may have one or more control point devices. To allow profile information such as user profile or network profile to be interchanged, the invention proposes providing a control point device firstly with an expanded device ascertainment service which can be used to find the other control point devices in the network and also with one or more additionally implemented profile services which allow the other control point devices in the network to be notified about change to profile information on a control point device.

The invention relates to the technical field of data communication in a network of distributed stations, particularly in a home network. A home network of this type allows AV data streams to be transmitted between network subscriber stations. The aim of the invention is to assist the user of a network of this type when he wishes to start a recording procedure for the audio and/or video data. In line with the invention, a data connection is automatically set up between that data source appliance which has already set up a connection to a data sink appliance or to a user interface appliance and the recording appliance. The automatic set-up of a data connection takes place directly after the user interface for the recording appliance has been called up. Alternatively, the automatic set-up of a data connection may take place only specifically after selection of the recording function on the recording appliance. The measure assists the implementation of an instant-recording function on the recording appliance in the network.

The invention relates to the field of home networks, in particular to the connection of two home networks of different types via a gateway. The network appliances in the network of the first type are also intended to be able to control the network appliances in the network of the second type, and vice versa. One problem that occurs when carrying out conversion processes on control messages is that an input parameter which is known in the network of the first type can be changed as required and can also be signaled further within this network, but the associated correspondence in the network of the second type is permanently set, and accordingly cannot be changed. The invention provides a way in which an input parameter such as this can nevertheless be likewise updated in the network of the second type.For this purpose, the network station which relates to the input parameter is first of all logged-off in the network of the second type. The changed input parameter is then converted to the information element in the network of the second type. The network station which relates to the input parameter is then logged on again in the network of the second type. This results in the network stations in the network of the second type being able to newly read the appliance description for the network station which relates to the input parameter. This then also results in the input parameter being updated in the network of the second type.

The invention relates to a bending sensor for detecting function parameters for the characterization of motion sequences at the human or animal body. The bending sensor comprises a fixing element 20, in particular a fixing plaster, for fixing the bending sensor on the skin of the human or animal body. Furthermore, a bending-sensitive detector 10 for detecting bending parameters of the bending sensor is provided. The detected bending parameters such as, for instance, the bending angle, the bending rate, and/or the bending acceleration are stored in a data memory 30. The fixing element is extensible and comprises an extensible cavity for accommodating a measuring sensor of the detector. The measuring sensor is fixed at a reference point of the fixing element in the cavity.
