ELECTRONIC DEVICE CAPABLE OF ADAPTIVELY ADJUSTING POWER BASED ON A DISTANCE FROM AN OBJECT AND OPERATING METHOD THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18223193 titled 'ELECTRONIC DEVICE CAPABLE OF ADAPTIVELY ADJUSTING POWER BASED ON A DISTANCE FROM AN OBJECT AND OPERATING METHOD THEREFOR
Simplified Explanation
The abstract describes an electronic device that uses a transceiver to transmit or receive wireless signals and a processor to detect the presence of objects based on signal characteristics.
- The device has a first detector to determine if an object is within a certain distance based on the power ratio of the wireless signal.
- If no object is detected within the first distance range, a second detector is used to check if the object is within a second distance range outside the first range, using a chirp pulse obtained by frequency-modulating the wireless signal.
- The transmission power of the wireless signal is adjusted based on whether the object is detected by the first or second detector.
---
- Potential Applications
- Intrusion detection systems
- Proximity sensors for automated doors
- Object tracking in smart homes or industrial settings
- Problems Solved
- Accurate detection of objects within specific distance ranges
- Efficient use of transmission power based on object detection
- Benefits
- Improved security measures
- Energy efficiency in wireless communication
- Enhanced automation capabilities in various applications
Original Abstract Submitted
An electronic device is provided. The electronic device includes: a transceiver configured to transmit or receive a wireless signal; and a processor configured to: control a first detector to detect whether an object is within a first distance range, based on a transmission/reception power ratio of the wireless signal; control a second detector to detect, based on the object not being detected within the first distance range, whether the object is within a second distance range outside the first distance range, based on a chirp pulse, which is obtained by frequency-modulating the wireless signal; and control transmission power of the wireless signal, based on whether the object is detected by the first detector or the second detector.
