Abstract: An operation method of a server for updating firmware includes: generating a first delta file including a plurality of blocks based on a plurality of update areas included in a first version firmware; generating a second delta file by repositioning the plurality of blocks included in the first delta file such that a plurality of unit blocks are generated by grouping control blocks, difference blocks, and extra blocks, each of which corresponds to the plurality of update areas, respectively; generating a plurality of swap blocks based on extra blocks among the plurality of blocks; and generating a third delta file by adding the generated plurality of swap blocks to the second delta file.

Abstract: A method and system for monitoring a biomedical signal employ a sensor module configured to output a continuous electrical signal by sensing the biomedical signal, a memory configured to store reference data, a transmitter configured to transmit output data via a wireless channel, and a data processing unit configured to determine whether to transmit input data via the transmitter as the output data, based on the input data, which is generated from the continuous electrical signal, and the reference data.
