SENSOR RELIABILITY DETECTION AND POWER MANAGEMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17933739 titled 'SENSOR RELIABILITY DETECTION AND POWER MANAGEMENT
Simplified Explanation
The present disclosure is directed to a wearable electronic device, such as a watch, that includes one or more optical sensors. The device detects whether or not the optical sensors are in physical contact with the user's skin in order to determine the accuracy of measurements. It does this by detecting the level of contact between the user's skin and the optical sensors based on electrostatic charge variation measurements, and generates a contact reliability index (CRI) based on this level of contact. The operation of the optical sensors is then adjusted based on the CRI.
- Optical sensors in wearable electronic device
- Detection of physical contact with user's skin
- Electrostatic charge variation measurements
- Contact reliability index (CRI)
- Adjustment of sensor operation based on CRI
Potential Applications
This technology could be applied in various wearable devices such as fitness trackers, smartwatches, and health monitoring devices.
Problems Solved
This technology solves the problem of inaccurate measurements by ensuring that the optical sensors are in proper contact with the user's skin.
Benefits
The benefits of this technology include improved accuracy of measurements, better user experience, and more reliable data for health and fitness tracking.
Potential Commercial Applications
One potential commercial application of this technology is in the healthcare industry for monitoring patients' vital signs and health metrics.
Possible Prior Art
One possible prior art could be devices that use optical sensors for measuring biometric data, but without the capability to detect the level of contact with the user's skin.
Unanswered Questions
How does the device adjust the operation of the optical sensors based on the contact reliability index (CRI)?
The article does not provide specific details on the process of adjusting the sensor operation.
What are the specific electrostatic charge variation measurements used to determine the level of contact between the user's skin and the optical sensors?
The article does not elaborate on the exact measurements or techniques used for detecting the level of contact.
Original Abstract Submitted
The present disclosure is directed to a wearable electronic device, such as a watch, that includes one or more optical sensors. In order to determine accuracy of measurements by the optical sensors, the device detects whether or not the optical sensors are in physical contact with the user's skin. The device detects a level of contact between the user's skin and the optical sensors based on electrostatic charge variation measurements, and generates a contact reliability index (CRI) based on the level of contact. Operation of the optical sensors are adjusted based on the CRI.
