Abstract

Det er beskrevet fremgangsmåter og anordninger for bevaring av batterienergi som brukes ved overføring av signaler som bærer data fra et sted nede i et borehull (4) ved hjelp av et transmisjonssystem hvor et forutbestemt sett data skal overføres en gang i løpet av en forutbestemt periode. Fremgangsmåten kan omfatte trinn hvor det sendes i et minste ett signal (D) i løpet av nevnte periode for å overføre datasettet og tidspunktet for å sende nevnte minst ene signal velges, idet i det minste noe av dataene som skal overføres, representeres ut fra tidspunktet for sending av nevnte minst ene signal.
