Publication number: 20090216100Abstract: The present invention relates to a method for wireless transmission of data between components of a blood glucose system (1, I1) including a master controller (2, 2?) having a receiver (10) and a transmitter (9), and at least one slave device (3) having a receiver (19) and a transmitter (18), and to a corresponding blood glucose system (1, I1). The slave device (3) is normally operated in a power saving mode in which its receiver (19) is only activated intermittently at a receiver activation frequency for a predetermined listening period. The controller (2, 21) transmits a communication initiation data frame to the slave device (3) by means of a signal comprising a preamble signal transmitted for a preamble period. Upon receipt of the communication initiation data frame, the slave device (3) is switched to a communication mode in which it transmits a response to the controller (2, 21), and the slave device (3) is switched from the communication mode to the power saving mode.Type: ApplicationFiled: April 20, 2006Publication date: August 27, 2009Applicant: LifeScan Scotland Ltd.Inventors: Manfred Ebner, Ulrich Kraft
