==Self-Mixing Interferometry Sensors Used to Sense Vibration of a Structural or Housing Component Defining an Exterior Surface of a Device - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18244023 titled 'Self-Mixing Interferometry Sensors Used to Sense Vibration of a Structural or Housing Component Defining an Exterior Surface of a Device

==Simplified Explanation==

The patent application describes a device that includes an electronic display, a cover, and an array of SMI sensors. The sensors are positioned on the same side of the cover as the display and emit electromagnetic radiation towards the interior surface of the cover or a component attached to it. The sensors generate outputs that indicate the vibration of the cover or the component. The device also includes circuitry to analyze the vibratory waveform using multiple sensor outputs.

* The device has an electronic display and a cover with sensors on the same side.
* SMI sensors emit electromagnetic radiation towards the cover or attached components.
* The sensors generate outputs that indicate the vibration of the cover or the component.
* The device includes circuitry to analyze the vibratory waveform using multiple sensor outputs.

==Potential Applications==
* This technology can be used in smartphones, tablets, or other electronic devices with displays.
* It can be applied in automotive displays or control panels to monitor vibrations.
* The device can be used in virtual reality or augmented reality headsets to track vibrations.

==Problems Solved==
* The device allows for the characterization of vibratory waveforms impinging on the device.
* It provides a way to monitor and analyze vibrations in electronic devices.
* The technology enables the detection of potential issues or malfunctions caused by vibrations.

==Benefits==
* The device provides a more comprehensive understanding of vibrations by using multiple sensor outputs.
* It allows for the identification of specific areas or components experiencing vibrations.
* The technology can help improve the durability and reliability of electronic devices by detecting and addressing vibration-related issues.


==Original Abstract Submitted==

A device includes an electronic display, a cover through which the electronic display projects an image, and an array of SMI sensors. The array of SMI sensors is positioned on a same side of the cover as the electronic display. Each SMI sensor is configured to emit electromagnetic radiation toward a respective portion of: an interior surface of the cover, or a surface of a component of the device attached to the cover; and generate a respective SMI output including information indicative of vibration of the respective portion of the cover or the component. The device also includes circuitry configured to characterize a vibratory waveform impinging on the device. The vibratory waveform is characterized using at least two of the SMI outputs.
