Abstract: A communication device includes one processor to run at least two operating systems simultaneously. The at least two operating systems include a first operating system for mobile station functions having a first group of threads, the mobile station functions including operations for communicating with another device, and a second operating system for data processing functions having a second group of threads, the data processing functions including operations for processing data internally in the communication device, where the operating systems communicate with each other. The communication device further includes at least one user interface, provides for generating an interrupt, provides for selecting a thread to execute as a result of the interrupt including a common interrupt handler for the at least two operating systems, and provides for transmitting interrupt data to the operating system from which the thread was selected, including the thread to execute.

Abstract: An embedded system (1) comprising at least one processor (2) for running an operating system (OS_A, OS_B). The embedded system (1) further comprises: means (17, 401, 412) for running at least two operating systems (OS_A, OS_B) in said processor (2), a first operating system (OS_A) comprising a first group of threads (THA1, THA2, THA_IDLE), a second operating system (OS_B) comprising a second group of threads (THB1, THB2, THB_IDLE), means (nFIQ, nIRQ, SWI) for generating an interrupt (FIQ, IRQ, SWI) to said processor (2), means for examining (401, 603, 617) to the execution of which thread (THA1, THA2, THB1, THB2, THA_IDLE, THB_IDLE) the interrupt (FIQ, IRQ, SWI), that has come to the processor (2), affects, and means (401, 412, 603, 609, 617) for transmitting interrupt data to said operating system (OS_A, OS_B) which relates to the thread (THA1, THA2, THB1, THB2, THA_IDLE, THB_IDLE) affecting the interrupt (FIQ, IRQ, SWI) received by the processor (2).

Abstract: The invention relates to a method and an apparatus for packing end covers of paper rolls and a package for end covers (2, 2a) of paper rolls. In the method, end covers (2, 2a) are compressed in a pile in the axial direction of the pile, after which the end cover pile is wrapped in a protective paper (1) and the edges (1a) of the paper are folded and fastened onto the outermost end covers (2a) of the end cover pile. The apparatus has compression surfaces between which the end covers (2, 2a) are stacked, rotating reels on which the end cover pile can revolve when it is compressed so that the protective paper (1) can be wrapped around the end cover pile, and fixing means with which the edges (1a) of the protective paper (1) are folded over the outermost end covers (2a) and fastened onto them with glue.
