Abstract
Abstract The invention relates to an X-ray device including a number of components to each of which is assigned a data transmission node working by the CAN protocol whose data input and data output are in mutual communication with other data transmission nodes via transmitters and receivers, the data transmission nodes being connected to the relevant associated components through connection lines. A fast and reliable data transmission is safeguarded in that the transmitter and receiver of at least some of the data transmission nodes are constructed for wireless transmission, and in that these transmitters or receivers are so controlled that they send data to at least the wireless receivers of other data transmission nodes and receive data from the wireless transmitters of at least the other data transmission nodes, as applicable.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
208 words
An X-ray device comprising a multiplicity of operative components which communicate automatically with each other and cooperate to form said X-ray device, a plurality of said operative components being controlled in response to control commands transmitted from other ones of said components and each of said operative components being assigned a data transmission node working by the Controller Area Network protocol, the data transmission nodes being in mutual communication with each other via a data transmission system for transmission of data between said components including transmission of said control commands to said plurality of controllable components, the data transmission nodes being connected to the relevant associated components through connection lines, wherein said data transmission system comprises a first wireless transmitter and a first wireless receiver serving a first group of one or more data transmission nodes, a second wireless transmitter and a second wireless receiver serving a second group of one or more data transmission nodes and a third wireless transmitter and a third wireless receiver serving a third group of one or more data transmission nodes, each of said wireless transmitters serving any particular group of nodes being positioned for simultaneous broadcast mode wireless communication with each of said wireless receivers serving any other group of nodes.
Claim 2
Dependent Claim
