Method and device for bidirectional IR data transfer between a medical treatment table and an operator control device
First Claim
1. A method for bidirectional IR data transfer between a medical treatment table and an operator control device which are subscribers in the IR data transfer and each comprise an IR transmitter and an IR receiver,wherein the data to be transferred by a subscriber are split into data blocks which are transmitted in succession, with a respective break being observed between the transmission of the individual data blocks,wherein data from another subscriber are transmitted within the breaks,wherein the transmission of a data block is preceded by a check to determine whether IR signals are present and is held until a predetermined waiting time has elapsed after the disappearance of the IR signal if IR signals are present,wherein the subscribers receive their transmitted signal themselves, check their transmitted signal, and retransmit the associated data if the signal has been disturbed,wherein the predetermined waiting time is selected at random, andwherein the predetermined waiting time for the operator control device is shorter than the predetermined waiting time for the medical treatment table.

Abstract
The invention presents a method and a device for bidirectional IR data transfer between a medical treatment table, particularly an operating table (10a to 10d), and an operator control device (12a to 12d) which are subscribers in the IR data transfer and which each comprise an IR transmitter and an IR receiver, where the data to be transferred by a subscriber (10a to 10d, 12a to 12d) are split into data blocks which are transmitted in succession, with a respective break being observed between the transmission of the individual data blocks, and where data from another subscriber are transmitted within the breaks.

11. A device for bidirectional IR data transfer between a medical treatment table and an operator control device, having a first IR data transfer unit which is arranged in the treatment table and which comprises an IR transmitter and an IR receiver, and having a second IR data transfer unit which is arranged in the operator control device and which comprises an IR transmitter and an IR receiver, in which the first and/or the second IR data transfer unit is programmed such that it splits data which are to be transferred into data blocks and transmits them in succession to the second or first data transfer unit,
wherein it observes a respective break between the transmission of the individual data blocks and where the second or first data transfer unit is programmed to transmit data to the first or second data transfer unit within the breaks, wherein the first and/or the second IR data transfer unit is programmed such that it checks whether IR signals are currently present, and if IR signals are present, then it holds transmission of the data block until a predetermined waiting time has elapsed until the disappearance of the IR signal, wherein the first and/or the second IR data transfer unit is programmed such that it receives its transmitted IR signal itself, checks it and, if the signal has been disturbed, retransmits the associated data, wherein the predetermined waiting time is selected at random, and wherein the predetermined waiting time for the operator control device is shorter than the predetermined waiting time for the medical treatment table.
