A sensor includes a control circuit set to a first operation mode in which an operation is prepared by receiving a clock signal from a processor and receiving an operation command from the processor. The sensor is configured to generate a first signal including a result of an operation corresponding to the operation command and a second signal indicating completion of the operation. An interface circuit is configured to transmit the first signal and the second signal to the processor. The control circuit is set to a second operation mode due to blocking of the clock signal by a control of the processor in response to the transmission of the second signal.

Low power sensor, processor, and data processing system including the sensor and the processor

A display driving circuit for receiving image data from a host and driving a display panel, the display driving circuit including: an interface configured to receive the image data from the host; and a timing controller configured to control a first interrupt signal for waking up the host in a low-power mode and to control a second interrupt signal based on a light emission control signal, wherein the light emission control signal is for controlling a light emission time of a pixel included in the display panel, and wherein the timing controller is further configured to control a level of the second interrupt signal based on whether the image data has started to be received from the host in response to the first interrupt signal and the second interrupt signal.

Display driving circuit, a host, a display system including the display driving circuit and the host, and an operation method of the display system

An apparatus and a method for controlling a home device using biometric information are provided. The method includes determining a reference sleep pattern among a plurality of sleep patterns based on sleep time information of a user or basic information of the user, analyzing a sleep state of the user based on biometric information of the user, comparing the reference sleep pattern with the sleep state, determining a sleep environmental condition when the reference sleep pattern is different from the sleep state, and controlling the home device based on the determined sleep environmental condition.

Home device control device and operation method thereof

Methods and apparatuses are provided in which a first terminal determines a delay offset value based on a first delay value of a first channel between the first terminal and an entity, and a second delay value of a second channel between the first terminal and the entity. The delay offset value is transmitted from the first terminal, to a second terminal. The second terminal uses the delay offset value to determine a third delay value of a third channel between the second terminal and the entity based on a fourth delay value of a fourth channel between the second terminal and the entity, the fourth delay value being determined by the second terminal.

Apparatus and method for calibrating delay between signal paths

A method is provided for operating a radio frequency (RF) receiver including a transimpedance amplifier, a capacitor selectively connected in parallel with the transimpedance amplifier, a channel selection filter unit connected to an output terminal of the transimpedance amplifier, and a variable gain amplification unit selectively connected in parallel with the channel selection filter unit. The method includes measuring signal-to-noise ratio from an output of the RF receiver, and comparing the measured signal-to-noise ratio with a reference signal-to-noise ratio. When the measured signal-to-noise ratio is greater than the reference signal-to-noise ratio, the capacitor is electrically disconnected from being connected in parallel with the transimpedance amplifier and a variation in the measured signal-to-noise ratio is measured. When the measured variation is in tolerance, the channel selection filter is bypassed to select the variable gain amplification unit.
