    Phoronix: Lenovo ThinkPad Palm Sensor Support Coming To Linux 5.11

    As part of Lenovo offering Linux pre-loaded on more laptops and desktops, they have been working on upstream improvements themselves along with their partners at Red Hat and others. One of the latest Lenovo-contributed improvements to the kernel is palm sensor support for newer ThinkPad notebooks...

            Strange, I wonder why the concern for wireless transmission strength based on users' proximity? What are the potentially harmful effects there?

              Google search for "WWAN transmit level safety" brought up a document from fujitsu with this passage:

              Low power wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low-level RF that does not produce heating effects causes no known adverse health effects.
              So I'm guessing it is a safety precaution to keep the WWAN from potentially heating a users palms when they're near and conversely when the palms aren't present it can attempt to ratchet up power levels for a performance boost?

                Any references to which ThinkPad models have this sensor?
