Abstract: The disclosure relates to techniques for controlling Specific Absorption Rate (SAR) of radio energy transmission. In particular, the disclosure relates to a radio device and a method for controlling radio energy transmission of a plurality of radio entities to comply with a predefined SAR requirement. Such a radio device includes: a plurality of radio entities configured to transmit radio energy; and a controller configured to control the radio energy transmission of the plurality of radio entities to comply with a predefined Specific Absorption Rate, SAR, requirement, wherein the controller is configured to enable at least two radio entities of the plurality of radio entities operating concurrently based on a shared SAR transmission power restriction which allows the at least two radio entities transmitting concurrently at a predefined duty cycle, in particular at 100% duty cycle, without violating the SAR requirement. The disclosure further relates to a method for dynamic management of a SAR budget across multiple radio entities.

Abstract: A system and related methods for determining an actual head angle of a mobile device user from an actual orientation of the mobile device and a relative orientation of the user's head to the mobile device. The actual orientation of the mobile device may be used as a landmark such that the relative orientation of the user's head to the mobile device may be used to approximate the actual head angle of the mobile device user. The determined actual head angle may be compared to a predetermined head angle corresponding to correct posture. If the actual head angle deviates from the predetermined head angle, a stimulus may be provided from the mobile device to encourage the user to rotate their head and/or reposition the mobile device such that their actual head angle aligns with the predetermined head angle.
