  • Publication number: 20240136067
    Abstract: A method for monitoring an object is provided. The method includes the steps of: in response to information on a behavior of a domestic animal being estimated from sensor data measured by a sensor for the domestic animal using a machine learning-based behavior recognition model, estimating health status of the domestic animal with reference to the information on the behavior of the domestic animal and a health criterion for the domestic animal; and determining first breeding information on the domestic animal to be provided to a user on the basis of the health status.

  • Patent number: 11918365
    Abstract: An electrocardiogram (ECG) measurement device for a vehicle is provided. The ECG measurement device includes an impedance compensator that corresponds to an electrode in contact with a body of a driver and configured to compensate an impedance of each of electrode signals received from the electrode. An electrode selector sequentially selects the electrode signals in response to receiving the electrode signals from the electrode. A differential amplifier differentially amplifies the electrode signals. In particular, each electrode signal has the compensated impedance. Additionally, a signal quality evaluator evaluates quality of an ECG signal output from the differential amplifier and a compensation controller then adjusts an impedance compensation value of each of the impedance compensators as a result of evaluating the quality of the ECG signal.

  • Patent number: 10871849
    Abstract: A display device with integrated touch screen is provided. The display device includes a panel configured to include a plurality of electrodes and to be division-driven in a display driving mode and a touch driving mode during one frame period, a display driver IC configured to apply a common voltage to the plurality of electrodes during the display driving mode, and an ROIC configured to apply, to the plurality of electrodes, a touch scan signal for sensing a touch when the touch driving mode is a first touch driving mode, and apply, to the plurality of electrodes, a touch scan signal for detecting a touch input position when the touch driving mode is a second touch driving mode.
