SYSTEM AND METHOD FOR RADIO FREQUENCY (RF) SENSING TO DETERMINE DEVICE PARAMETERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17839842 titled 'SYSTEM AND METHOD FOR RADIO FREQUENCY (RF) SENSING TO DETERMINE DEVICE PARAMETERS

Simplified Explanation

The abstract describes a device for RF sensing that can communicate over both unlicensed and licensed frequency bands. The device uses antennas to transmit a unique signal and receive a corresponding return signal. The received signal is processed to determine its amplitude and phase, and this information is stored in a look-up table. The device then uses this information to determine its use state or gesture and adjust its operating parameters accordingly.

  • The device can communicate over both unlicensed and licensed frequency bands.
  • It uses antennas to transmit and receive signals.
  • The received signal is processed to determine its amplitude and phase.
  • The amplitude and phase information is stored in a look-up table.
  • The device uses this information to determine its use state or gesture.
  • It can then adjust its operating parameters based on the determined state or gesture.

Potential Applications

  • Smartphones and other mobile devices could use this technology to automatically adjust their settings based on how they are being used or held.
  • Internet of Things (IoT) devices could use this technology to optimize their performance based on their surroundings or user interactions.
  • Industrial equipment could benefit from this technology by automatically adapting to different operating conditions or user actions.

Problems Solved

  • This technology solves the problem of manually adjusting device settings based on user actions or environmental conditions.
  • It eliminates the need for complex user interfaces or external sensors to determine device use state or gesture.
  • It allows for more efficient and optimized operation of devices in various scenarios.

Benefits

  • The device can automatically adjust its operating parameters, providing a more seamless and user-friendly experience.
  • It reduces the need for manual intervention or configuration, saving time and effort for users.
  • It enables devices to adapt to different use cases or environments, improving their performance and efficiency.


Original Abstract Submitted

A device for RF sensing includes communication circuitry configured to communicate over an unlicensed frequency band and a licensed frequency band, the communication circuitry configured to transmit a unique signal over the unlicensed frequency band using at least one antenna of the one or more antennas and receive a corresponding return signal from at least one antenna of the one or more antennas, the at least one receiver configured to process the corresponding return signal to determine at least an amplitude and phase (td) of the corresponding return signal, and a look up table (LUT) having characterization information relating to the amplitude and phase (td) of the corresponding return signal, wherein the device is configured to use the characterization information to determine a use state or a gesture of the device and alter at least one operating parameter of the device based on the determined use state or gesture.
