==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 20240081663 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 non-invasively estimate bio-information by measuring a photoplethysmogram (PPG) signal and analyzing it to determine whether the bio-signal is normal. The processor in the apparatus extracts 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, and uses this information to determine the normalcy of the PPG signal.

* PPG sensor measures PPG signal from an object
* Processor analyzes second derivative signal of PPG signal to extract pairs of local maximum and minimum points
* Processor selects at least one reference pair from the extracted pairs
* Processor determines whether PPG signal is normal based on selected reference pair

== Potential Applications ==
This technology could be used in various medical devices and wearable health monitors to provide real-time monitoring and analysis of bio-signals.

== Problems Solved ==
This technology helps in quickly and accurately determining the normalcy of bio-signals, which can aid in early detection of health issues or abnormalities.

== Benefits ==
The non-invasive nature of the apparatus makes it convenient and comfortable for users to monitor their bio-information regularly. The real-time analysis provided by the processor can help in prompt medical intervention if any abnormalities are detected.

== Potential Commercial Applications ==
* Healthcare industry for medical devices and monitoring systems
* Fitness industry for wearable health trackers

== Possible Prior Art ==
One possible prior art could be the use of PPG sensors in wearable devices for monitoring heart rate and other bio-signals. However, the specific method of analyzing the second derivative signal to determine normalcy may be a novel aspect of this patent application.

=== What is the accuracy rate of determining normalcy based on the selected reference pair?
The patent application does not provide specific information on the accuracy rate of determining normalcy based on the selected reference pair.

=== How does the apparatus handle variations in PPG signals due to different factors such as age, gender, or health conditions?
The patent application does not elaborate on how the apparatus adjusts for variations in PPG signals due to different factors such as age, gender, or health conditions.


==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.
