Samsung patents device that adjusts wireless power based on nearby objects
The filing describes an electronic device that uses a wireless signal to detect objects at different distances. It first checks for close objects using signal strength, then uses a frequency-modulated pulse to find objects further away, adjusting the transmission power accordingly.
In the filing’s own words
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.
What exactly they claim (claim 1)
1. An electronic device comprising: a transceiver configured to transmit or receive a wireless signal; and a processor configured to: control a first detector to set a first threshold based on a noise level, and detect whether an object is within a first distance range, based on a transmission/reception power ratio of the wireless signal and the first threshold; 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.
