Abstract: The embodiments disclosed herein provide an electrocardiogram data processing server, an electrocardiogram data processing method, and a computer program. The embodiments disclosed herein further provide an electrocardiogram data processing server, an electrocardiogram data processing method, and a computer program, the electrocardiogram data processing server configured to determine whether analysis is required while segmenting an electrocardiogram signal into signal segments with variable window sizes, for instance, by changing a window size of a signal segment according to whether analysis of a previous signal segment is required.

Abstract: The present disclosure relates to a pixel circuit and pixel driving apparatus technology. In this technology, two LEDs are arranged in parallel and selectively used in a hybrid manner in which a PWM (pulse width modulation) scheme for supplying a ramp voltage as a gate voltage for a transistor arranged within a pixel and for turning off the LEDs at the moment when the gate voltage becomes equal to a threshold voltage and a PAM (pulse amplitude modulation) scheme for determining a starting value of the ramp voltage based on a grayscale value of the pixel are combined.

Abstract: A cylindrical secondary battery and a manufacturing method of a secondary battery are provided. A manufacturing method of a cylindrical secondary battery includes: winding an electrode assembly to expose a first electrode uncoated portion and a second electrode uncoated portion to opposite ends in a longitudinal direction; bending at least some portions of the first electrode uncoated portion and the second electrode uncoated portion of the electrode assembly in a direction by pressing the first electrode uncoated portion and the second electrode uncoated portion; welding electrode collector plates to ends of the bent first and second electrode uncoated portions; and inserting and sealing the electrode assembly into a cylindrical case.

Abstract: A CMOS input buffer for converting the TTL level signals to the CMOS level signals, thereby being capable of stably operating within all allowable range of the power supply voltage, is disclosed. Said CMOS input buffer includes an inverter, a reference voltage generating circuit, a power supply voltage tracer circuit and an input circuit. The input circuit includes P-channel MOS transistors and N-channel MOS transistors so as to supply a stable logic output in response to the input signal of TTL level, regardless of variation of the power supply voltage Vcc, under the control of a voltage that is approximately proportional to the difference between the reference voltage and the power supply voltage within a fixed range of the power supply voltage.
