Abstract: Disclosed are a power stabilization circuit and a display device to which the power stabilization circuit is applied. The power stabilization circuit includes a thermistor provided on a first path through which an input power is supplied, to limit an inrush current of the power, a relay that provides a second path through which the power is supplied without passing through the thermistor, to allow the power to be transferred through the second path instead of the first path when a current is supplied, and a switching circuit that is switched to supply the current generated from the input power to the relay when an activation signal for activating at least one of a display and a backlight of the display is received.

Abstract: Embodiments herein achieve a method and system for selecting non-coherent spreading sequences with binary alphabets {0, 1} with variable spreading factors. The method generates circular shift equivalent sets of spreading sequences by circularly shifting base sequences with elements {1, 0} and having at least one variable spreading factor. The method determines whether each spreading sequence in the circular shift equivalent set meets pre-defined spreading sequence criteria. The spreading sequence criteria comprise balanced criteria, a non-repetition criteria, non-circular criteria, and conjugate criteria. Furthermore, the method selects the spreading sequence from expansions of at least one spreading sequence from the circular shift equivalent sets in response to determining that the spreading sequences in the circular shift equivalent sets meets the pre-defined spreading sequence criteria.

Abstract: Provided is a data transmission system of providing preambles of different classes according to a characteristic of a terminal. A terminal having constraints on using a power with respect to a data reception may receive only a preamble of a particular class and thus decrease a power consumption. A general terminal may receive preambles of plural classes and quickly receive data.

Abstract: An electronic device according to an aspect of the present disclosure includes a touch screen. The electronic device includes a communication interface that may receive, from a touch pen, a pulse wave signal of a user which is measured from a finger of the user by the touch pen while the touch pen is placed on the touch screen. The electronic device includes a processor that may determine whether a measurement posture of the user is appropriate based on whether the finger touches the touch screen, and in response to determining that the user's measurement posture is appropriate, estimate bio-information of the user based on the received pulse wave signal.
