APPARATUS FOR ESTIMATING BIO-INFORMATION AND METHOD OF DETECTING ABNORMAL BIO-SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18118562 titled 'APPARATUS FOR ESTIMATING BIO-INFORMATION AND METHOD OF DETECTING ABNORMAL BIO-SIGNAL
Simplified Explanation
The apparatus described in the patent application is designed to estimate bio-information non-invasively and determine whether a bio-signal is normal. Here are the key points of the invention:
- Includes a photoplethysmogram (PPG) sensor to measure a PPG signal from an object
- Utilizes a processor to extract pairs of local maximum and minimum points from the second derivative signal of the PPG signal
- Selects at least one reference pair from the extracted pairs
- Determines the normalcy of the PPG signal based on the selected reference pair
Potential applications of this technology:
- Healthcare industry for monitoring vital signs
- Fitness tracking devices for assessing physical activity levels
- Biometric security systems for identity verification
Problems solved by this technology:
- Provides a non-invasive method for estimating bio-information
- Allows for quick and accurate assessment of bio-signals
- Helps in early detection of abnormalities in bio-signals
Benefits of this technology:
- Enables real-time monitoring of health parameters
- Improves the efficiency of medical diagnosis
- Enhances the accuracy of fitness tracking devices
Original Abstract Submitted
An apparatus for non-invasively estimating bio-information and a method of determining whether a bio-signal is normal by the apparatus for estimating bio-information are provided. The apparatus for estimating bio-information according to an embodiment of the disclosure includes: a photoplethysmogram (PPG) sensor configured to measure a PPG signal from an object; and a processor configured to extract a plurality of pairs of local maximum points and local minimum points from a second derivative signal of the PPG signal, to select at least one reference pair from among the extracted plurality of pairs, and to determine whether the PPG signal is normal based on the selected at least one reference pair.
