Abstract: Disclosed are an electric power conversion apparatus and method in an energy harvesting system. In more detail, it is possible to obtain the maximum electric power from the plurality of energy sources by selecting the connection structure between the source terminals or the connection structure between the source terminals and the collection terminals using the electrical characteristic values (for example, open voltage, short current, and internal impedance) of each source and adjusting the load impedance in the selected connection structure in the energy harvesting system.

Abstract: The present disclosure relates to a capsule endoscope transmitter configured to transmit frames including control frames and data frames to a capsule endoscope receiver. The capsule endoscope transmitter includes a preamble generator configured to generate preambles for synchronizing and identifying the control frames used to select a reception electrode pair that receives the frames, and a line sync generator configured to generate a line sync for synchronizing the data frames and identifying a code value of each of the data frames.

Abstract: Provided is a method for generating a preamble of a transmission signal for human body communication, the method including using a frequency shift code (FSC) of which a length is adjusted according to an operating clock frequency or a transmission rate and a first pseudo random binary sequence (PRBS) code of p chips where p is a natural number to generate a first preamble unit block of n chips where n is a natural number, using the FSC and a second PRBS code of p′ chips to generate a second preamble unit block of n′ chips, and arraying the first preamble unit block consecutively and repeatedly and disposing the second preamble unit block at a next stage to form the preamble of the transmission signal.
