Background Noise Recorder - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240333325 titled 'Background Noise Recorder

The abstract describes an electronic device with wireless circuitry that can accurately measure the range between the device and an external object within an ultra-short range domain.

• The device includes a transmit antenna for sending signals and a receive antenna for receiving reflected signals.
• When the range exceeds a first threshold, the device records background noise using the transmitted and received signals.
• When the range is below a second threshold, the device uses the recorded background noise to detect the range based on the reflected signals.
• This technology allows for precise range measurement even when the device is in different cases or on various surfaces.

Potential Applications: - Proximity sensing in smartphones and other electronic devices - Indoor navigation systems - Object detection in robotics and autonomous vehicles

Problems Solved: - Accurate range measurement in ultra-short distances - Consistent performance across different device placements

Benefits: - Improved accuracy in proximity detection - Enhanced user experience in various applications - Increased reliability in object detection systems

Commercial Applications: Title: Ultra-Short Range Proximity Sensing Technology for Enhanced User Experience This technology can be utilized in smartphones, smart home devices, industrial automation, and automotive applications to provide precise proximity sensing capabilities, leading to improved user interactions and operational efficiency.

Questions about Ultra-Short Range Proximity Sensing Technology: 1. How does this technology compare to traditional proximity sensors in terms of accuracy and reliability? 2. What are the potential challenges in implementing this technology in different environments and conditions?

Original Abstract Submitted

an electronic device may include wireless circuitry with a transmit antenna that transmits signals and a receive antenna that receives reflected signals. the wireless circuitry may detect a range between the device and an external object based on the transmitted signals and the reflected signals. when the range exceeds a first threshold, the wireless circuitry may use the transmitted signals and received signals to record background noise. when the range is less than a second threshold value, the wireless circuitry may detect the range based on the reflected signals and the recorded background noise. this may allow the range to be accurately measured within an ultra-short range domain even when the device is placed in different device cases, placed on different surfaces, etc.
