发明名称 Detection of a simultaneous occurrence of an event at a plurality of devices
摘要 The invention relates to a detection of a simultaneous occurrence of an event of a predetermined kind at a plurality of electronic devices. At least two devices detect the event and record at their end the time elapsing after this detection. Then, a communication channel is established between the devices. Once the communication channel has been established, an indication of the recorded elapsed times can be exchanged. At least one of the devices compares a recorded elapsed time with an indicated elapsed time received from another device. If both elapsed times are similar to each other, it can be assumed that the event occurred simultaneously at both devices. The invention relates equally to corresponding devices, to a corresponding data transfer system and to corresponding software program products.
