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.

Abstract: A method and an apparatus reduce power used when a traffic load is low in a base station of a wireless communication system. The base station monitors a traffic load. When the traffic load is lower than a predetermined threshold and a Multiple Input Multiple Output (MIMO) mode is used to communicate with a mobile station, the MIMO mode is converted to a Single Input Multiple Output (SIMO) mode. The base station performs communication with the mobiles stations by using the SIMO mode. According to another embodiment, when the traffic load is lower than a predetermined threshold, the base station limits the number of Resource Blocks (RBs) that may be allocated to a coverage area of the base station. A Power Amplifier (PA) bias related to a transmission output of the base station is reduced based on the limited number of RBs, thereby saving power consumption of the base station.
