SYSTEM FOR SYNCHRONISING EEG WITH AUXILIARY OUTPUT, IN PARTICULAR VIDEO
First Claim
1. A system for monitoring a patient'"'"'s EEG output comprising an EEG recorder operative to generate an EEG output indicative of electrical activity produced by the brain of a patient, an auxiliary recorder operative to generate an auxiliary output indicative of another characteristic of the patient, and an electronic data processor operative to receive the EEG recorder output and the auxiliary output, the system being operative to generate synchronisation data indicative of when the EEG output and when the auxiliary output occurred with reference to a datum signal, the electronic processor being operative to process the synchronisation data to subsequently synchronise the playback of the EEG output with the auxiliary output, wherein the electronic data processor is operative to apply a compensation factor to at least one of the EEG and auxiliary outputs that accounts for the latency of transmission of the at least one output from the recorder to the electronic data processor, the latency being a value indicative of the time delay between the respective recorder transmitting the output and the electronic data processor receiving the output.

Abstract
A system for monitoring a patient'"'"'s EEG output comprises an EEG recorder operative to generate an EEG output indicative of electrical activity produced by the brain of a patient, and an auxiliary recorder operative to generate an auxiliary output indicative of another characteristic of the patient. The auxiliary recorder may comprise a video recorder. An electronic data processor is operative to receive the EEG recorder output and the auxiliary output, the system being operative to generate synchronisation data indicative of when the EEG output and when the auxiliary output occurred with reference to a datum signal. The electronic processor is operative to process the synchronisation data to subsequently synchronise the playback of the EEG output with the auxiliary output. A compensation factor accounts for transmission latency.

24. An EEG recorder for use with a system for monitoring a patient'"'"'s EEG output, the system comprising an electronic data processor operative to receive an auxiliary output generated by an auxiliary recorder, the EEG recorder being operative to generate an EEG output indicative of electrical activity produced by the brain of a patient, the EEG recorder further comprising transmission means to transmit the EEG output to the electronic data processor with synchronisation data indicative of when the EEG output occurred with reference to a datum signal, the synchronisation data being capable of being processed by the electronic data processor to enable the electronic data processor to subsequently synchronise playback of the EEG output with the auxiliary output.

25. An electronic data processor operative to receive an EEG output indicative of electrical activity produced by the brain of a patient, and to receive an auxiliary output indicative of another characteristic of the patient from an auxiliary recorder, the electronic data processor being controlled to process synchronisation data indicative of when the EEG output and the auxiliary output occurred so as to subsequently synchronise the playback of the EEG output with the auxiliary recorder output, wherein the electronic data processor is operative to apply a compensation factor to at least one of the EEG and auxiliary outputs that accounts for the latency of transmission of the at least one output from the recorder to the electronic data processor, the latency being a value indicative of the time delay between the respective recorder transmitting the output and the electronic data processor receiving the output.
