Huawei applied for a patent in the medical devices

Huawei Technologies Co. Ltd has applied for a new patent in the medical devices, it will be used in the ECG measuring. The latest Patent has need registered with a publication No. CN108601544B. According to the device for ECG measurement according to the embodiment of the present invention, the digital ECG signal converted from the collected analog ECG signal is filtered, and the interference signal caused by the hardware link is filtered out to improve the accuracy of the signal.

This patent was applied for on July 29, 2016. The patent describes the use of multiple potential sensors to capture electrical signals, and then signal processing through signal amplifiers, analog-to-digital converters, filters, etc., to obtain effective ECG signals.

According to the description, the electrocardiogram (ECG) is an objective indicator of the occurrence, transmission and recovery of heart excitement.

This invention patent can be applied to smart scales. First, the two potential sensors on the left and right feet are used to collect analog signals and sense the changes in the potential difference between the feet. Thereafter, the conversion chip converts the analog ECG signal into the first digital ECG signal.
