An apparatus for detecting the location of a foreign material of a low-voltage battery cell includes a first and second measurement electrodes respectively on a positive electrode and a negative electrode of the battery cell to measure a leakage current; a current measuring device to measure a leakage current; and a data processor to process a measured leakage current data. The first and second measurement electrodes each have a structure in which a plurality of unit electrodes to which coordinate information is assigned are collected. The current measuring device measures a leakage current flowing through the unit electrode of the first measurement electrode and the unit electrode of the second measurement electrode that have the same coordinate information. The data processing part checks the location of a foreign material from a leakage current data through a coordinate information of a unit electrode having a large leakage current.

Apparatus for detecting location of foreign material of low-voltage battery cell and analytical method using the same

Provided are a method for measuring blood pressure information and a blood pressure measuring apparatus using the same as which improve the battery efficiency, the possibility of portability, and easy measurement of the device equipped with the blood pressure measurement function by both minimizing power consumption and optimizing signal delivery system in the measurement of the blood pressure information using ECG and PPG. The blood pressure measuring apparatus includes a first peak detection unit for detecting a first peak information from an electrocardiographic signal of a patient obtained from an electrocardiogram detection unit; a second peak detection unit for detecting a second peak information from an optical pulse waveform detection signal of the patient obtained from an optical pulse wave detection unit; and a control unit for calculating a pulse wave arrival time information indicating a blood pressure information depending on the first peak information and the second peak information.
