Communication device for establishing a data connection between intelligent appliances
First Claim
1. A communication apparatus for setting up a data connection between intelligent devices, comprising:
- a transmission oscillator for carrying out a contactless data exchange, said oscillator including a coil;
a communication element which is connected to the coil and the data processing component of an intelligent device and which emits search signals via the coil to receive a response from another intelligent device, a measuring device for monitoring a property of the transmission oscillator which outputs a control signal when ascertaining a change of the monitored property, and a switching apparatus which is connected to the measuring device and the communication element and which switches on the communication element when it has received a control signal from the measuring device.

Abstract
The invention relates to a communication apparatus for automatically setting up a data connection between two intelligent devices (10, 20, 30). The apparatus comprises a coil (13, 23, 33) for carrying out a contactless data exchange which is part of a transmission oscillator (50), a communication element (12, 22) which is connected to the coil (13, 23, 33) and the data processing component (11, 21) of an intelligent device (10, 20, 30) and emits search signals via the coil (13, 23, 33) to receive a response from another intelligent device (10, 20, 30), a measuring device (14, 24) for monitoring a property of the transmission oscillator (50), which outputs a control signal when ascertaining a change in the monitored property, and a switching apparatus (15, 25) which is connected to the measuring device (14, 24) and the communication element (12, 22) and which switches on the communication element (12, 22) when it has received a control signal from the measuring device (14, 24).
