Definitions

• the invention relates to a device of the type specified in the preamble of claim 1.
• the mobile phone In addition to purse and keychain, the mobile phone is now one of the items of daily use, which carries a large part of the population constantly.

• a similar known device serves the purpose of giving the owner of a mobile device, in particular a mobile phone, a warning in the event that he leaves his mobile device unintentionally in a motor vehicle.
• the device compares two states that result when the person in question is in the vehicle or outside the vehicle.
• devices of the type described last can serve the saving of energy, but are otherwise not very flexible, since they suggest only a manual change of the transmission pulses as a function of the distance that can cover a person in a given time. If this distance is therefore fixed, further energy saving is not possible. In addition, it is od for the users of mobile phones. The like. Impossible if they constantly have to worry about the respective setting of the distances and / or the height of the emitted pulses. Apart from that, the known device z. B.
• the times and / or the frequencies of the query cycles are automatically adapted to the current context.
• Context is understood in the context of the invention to mean a situation or a state in which the devices themselves and the users of the devices are currently located. So there are contexts that have a high query frequency of z. B. once per second, for example, when the user leaves his car or a train (context: "user gets off”). Here is the likelihood that an object to be monitored will be forgotten. Therefore, according to the invention, a check of the objects to be monitored is carried out at short intervals in order to warn the user as quickly as possible. In another context, for example, the user drives in his car on the highway or by rail (context: "user drives in the car or by train”).
• the likelihood that an item to be monitored will be forgotten or otherwise lost is less than in the context of disembarkation.
• the query frequency is therefore z. B. reduced to a query cycle every twenty seconds.
• Corresponding changes in the intensity with which the polling cycles are performed may be useful if the user of an item to be monitored is approaching people, or the user is viewing areas or locations, e.g. B. stations, with increased theft risk.
• the drawing shows a central unit 1, which is integrated, for example, in a laptop, a mobile phone or a PDA (personal digital assistant).

This can be done, for example, by a device number assigned only once and contained in the transmitted data. If the central unit 1 receives such a data response, it can conclude, based on the known range of the data exchange method used, that the object 2 is still in its environment.
• Radio technology determines whether the monitored item 2 is recognized as being "within an environment” or "outside of an environment.” Therefore, the range of the short-range radio technology used can be suitably adapted to the requirements of the respective device, for example by reducing the transmission power of the corresponding transmission devices.

Does the user drive z. B. in the car, then the context is "user drives car". In this context, the likelihood that an object to be monitored will be lost or stolen is low. Thus, in this context, the polling frequency can be reduced according to the invention.

For example, the adaptation means 10 can access a data memory (not shown) in which a plurality of contexts are each assigned a specific query frequency and / or one or more query times. Based on these information associated with the respectively recognized context, the adaptation means 10 sends a trigger signal for a polling cycle to the controller 4 whose input is connected to the output of the adaptation means 10.
