Heart Measurement Using Time-Varying Frequency Acoustic Techniques - A simplified explanation of the abstract
This abstract first appeared for US patent application 18460484 titled 'Heart Measurement Using Time-Varying Frequency Acoustic Techniques
Simplified Explanation
The patent application describes a technology where an ultrasonic wave is emitted from a speaker in a head-worn device, and a microphone in the device picks up the signal as it reflects off the user's ear to determine heart activity, such as heart rate.
- Ultrasonic wave emitted from speaker
- Microphone picks up reflected signal from user's ear
- Heart activity, like heart rate, determined based on microphone signal
Potential Applications
This technology could be used in various applications such as:
- Health monitoring devices
- Fitness trackers
- Medical devices for heart rate monitoring
Problems Solved
This technology helps in:
- Non-invasive heart rate monitoring
- Continuous heart rate monitoring without the need for direct contact with the skin
Benefits
The benefits of this technology include:
- Convenience for users
- Accurate heart rate monitoring
- Real-time heart rate data collection
Potential Commercial Applications
The potential commercial applications of this technology could be in:
- Wearable health and fitness devices
- Medical monitoring equipment
- Wellness apps and services
Possible Prior Art
One possible prior art could be the use of ultrasonic waves for various sensing applications, including distance measurement and object detection. However, the specific application of using ultrasonic waves for heart rate monitoring through reflection off the ear may be novel.
Unanswered Questions
How does the technology handle interference from external noise sources?
The patent application does not provide details on how the system deals with potential interference from external noise sources that could affect the accuracy of heart rate monitoring.
What is the range of heart rate values that can be accurately measured using this technology?
The patent application does not specify the range of heart rate values that can be accurately determined using the described system.
Original Abstract Submitted
An ultrasonic wave is output from a speaker of a head-worn device. A microphone signal is obtained from a microphone of the head-worn device that senses the ultrasonic wave as it reflects off an ear of a user. Heart activity such as a heart rate of the user is determined based at least on the microphone signal. Other aspects are also described and claimed.
