Abstract: According to an aspect, there is provided an apparatus for power management of a system on a chip, SoC. The apparatus comprises means for performing the following. The apparatus maintains, in a memory, a knowledge-based system comprising a plurality of rules. Each rule maps a shift from a first to a second SoC state to a set of one or more sequential actions for activating a power tree configuration corresponding to said second SoC state. The apparatus receives a request for adjusting a current power tree configuration so as to match a target SoC state. The apparatus determines a set of one or more sequential actions for activating an optimal power tree configuration for the SoC based on the knowledge-based system using current and target SoC states as an input. Finally, the apparatus adjusts the current power tree configuration according to the set of one or more sequential actions.

Abstract: A bootloader comprises software instructions for execution by a processor of an electronic processing device. The bootloader comprises an interpreter for interpreting a boot script stored in a memory of the processing device, and an integrity checker for checking the integrity of boot scripts stored in the memory. The bootloader comprises instructions for using the integrity checker to check the integrity of a first boot script of a plurality of boot scripts stored in the memory. The bootloader also comprises instructions for using the integrity checker to check the integrity of a second boot script of the plurality of boot scripts stored in the memory, independently of the integrity of the first boot script. The interpreter comprises instructions for interpreting a control-flow command in the first boot script, the control-flow command conditionally or unconditionally causing the bootloader to start interpreting commands from the second boot script.

Abstract: A set of profiles for forming complex profiles comprises two profiles, namely a first profile (10) and a second profile (20), adjoining each other and having walls surrounding a main chamber. Each profile (10, 20) of the set has an outer shape which may be inscribed into a triangle, and has an inner wall (12, 22) with a faying face (13, 23) without protruding fragments. The faying faces (13, 23) adjoining each other, after being coated with adhesive enable a joint to be created when the complex profile is discussed, however, in the case of the set of the profiles they are considered to be contact surfaces.
