A METHOD OF SYNCHRONIZING COMMUNICATIONS MEANS IN A BATTERY TO COMMUNICATIONS MEANS IN AN ELECTRONIC DEVICE, AN APPARATUS, AND A BATTERY

摘要

The invention relates to method of synchronizing a second communications means in a battery attached to an electronic device to a first communications means in said electronic device, wherein bytes consisting of a nubmer of bits are transmitted between said electronic device and said battery by means of said first and second communications means using digital, serial communication. A predetermined bit sequence is appended to at least some bytes prior to the transmission from said first communications means to said second communications means. Said bit sequence is detected in the signal received by said second communications means. The time interval between given shifts in the detected bit sequence is measured, and said synchronization is performed by means of said measured time interval. The invention also relates to a battery and an apparatus including a battery having communications means which is adapted to be synchronized in accordance with a received signal.
