Electronic Devices with Doppler-Based Object Detection - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240094374 titled 'Electronic Devices with Doppler-Based Object Detection
Simplified Explanation
The abstract describes an electronic device that uses radar signals to detect external objects and adjust its transmit power level accordingly to comply with regulatory limits on radio-frequency exposure.
- Sensing circuitry transmits radar signals and receives reflected signals over a set of antennas.
- Communications circuitry uses the antennas to transmit data subject to a maximum power level.
- Doppler information is generated based on the reflected signals to detect external objects on the device's surface.
- If an external object is detected off the surface within the hot-spot cone of the antennas, the transmit power level is reduced to comply with regulatory limits.
- If the external object is not within the hot-spot cone, the communications data is transmitted without reducing the maximum power level.
Potential Applications
This technology could be applied in:
- Smartphones and tablets to automatically adjust transmit power based on nearby objects.
- IoT devices to ensure compliance with RF exposure regulations.
Problems Solved
This technology solves the problem of exceeding regulatory limits on radio-frequency exposure by automatically adjusting transmit power based on the presence of external objects.
Benefits
The benefits of this technology include:
- Ensuring compliance with RF exposure regulations.
- Optimizing transmit power levels for efficient communication.
Potential Commercial Applications
Potential commercial applications of this technology include:
- Consumer electronics manufacturers looking to enhance safety and regulatory compliance in their products.
Possible Prior Art
One possible prior art for this technology could be radar-based proximity sensors used in automotive applications to detect objects around a vehicle.
Unanswered Questions
How does the device differentiate between external objects and other interference in the environment?
The abstract does not provide details on how the device distinguishes between external objects and other sources of interference that may affect the radar signals.
What specific regulatory limits on radio-frequency exposure does the device aim to comply with?
The abstract does not specify the exact regulatory limits that the device is designed to adhere to in terms of radio-frequency exposure.
Original Abstract Submitted
an electronic device may include sensing circuitry that transmits radar signals and receives reflected signals over a set of antennas. communications circuitry may use the antennas to transmit communications data subject to a maximum transmit power level. the sensing circuitry may generate doppler information based on the reflected signals and may detect whether an external object is on a surface of the device based on the doppler information. when the external object is detected on the surface, the external object is not within a hot-spot cone of the antennas and the communications circuitry may transmit the communications data without reducing the maximum transmit power level. when the external object is detected off the surface, the external object may be within the hot-spot cone and the communications circuitry may transmit the communications data with a reduced maximum transmit power level to satisfy regulatory limits on radio-frequency exposure or absorption.
