Abstract: A power control system provides multiple supply voltages that are guaranteed not to violate boundary conditions regardless of the timing of voltage change commands. A first voltage (Vlogic in the embodiments described herein) is controlled conventionally, and a second voltage (Vmemory) is either selected or generated by adding a selected offset to the first voltage. Both the size of the offset, and the absolute value of the second voltage, are constrained at all times, by constraint values specific to the current voltage zone. The invention ensures a smooth transition between different voltage operating points, and ensures that the trajectory of change between specified operating points remains within predefined boundaries.

Abstract: The invention concerns a supply air terminal device (10) and a method for regulating the airflow rate. The supply air terminal device (10) comprises a heat exchanger (11), with which a circulated airflow (L2) conducted from a room can be either cooled or heated. The supply air terminal device (10) comprises a mixing chamber (12), into which mixing chamber (12) the air chamber's (15) nozzles (16a1, 16a2 . . . 16an) or a flow gap (16) open to conduct a primary airflow (L1) into the mixing chamber (12), whereby the primary airflow (L1) from the nozzles (16a1, 16a2 . . . 16an) or through the flow gap (16) as a flow (Qs) will induce a circulated airflow (L2) from the room (H) to flow through the heat exchanger (11) into the mixing chamber (12). The combined airflow (L1+L2) is conducted into the room (H). The supply air terminal device (10) comprises a regulator (100) bypassing the nozzles (16a1, 16a2 . . .
