Abstract: A primary device may run a software application requiring a compute task. The primary device may receive statistics from a set of secondary devices over wireless communication links. The primary device may process the statistics to determine whether the compute task will be offloaded to the secondary devices or performed locally. The primary device may generate a distribution scheme for the secondary devices based on the statistics. This may involve modeling first delays associated with transmission of signals from the primary device to the secondary devices, second delays associated with transmission of compute results from the secondary devices to the primary device, and third delays associated with processing resources of the secondary devices. The optimized distribution scheme may minimize overall runtime of the compute task given the modeled delays, scheduling grants for the secondary devices, and a radio resource allocation for the secondary devices.

Abstract: A primary device may run a software application requiring a compute task. The primary device may receive statistics from a set of secondary devices over wireless communication links. The statistics may include parameters associated with the compute and communication capabilities of the secondary devices. The primary device may predict, based on the statistics, an expected performance gain in distributing the compute task to the secondary devices relative to performing the compute task locally. If the expected performance gain is high enough, the primary device may distribute shares of the compute task to the secondary devices over the wireless communication links. If the expected performance gain is low enough, the primary device may perform the compute task locally. If the expected performance gain is moderate, the primary device may update the set of secondary devices and/or may update a coding and distribution scheme for the compute task.

Abstract: A compressed-air system having a safety function and a method for operating such a compressed-air system. The compressed-air system contains two working valves, which each can selectively assume an aerating position that aerates a load and a venting position that vents the load. Both working valves are redundantly connected on the output side to the load by means of a separating device. The separating device allows one or the other of the working valves to be separated, while the aeration of the load is maintained, in order to subject the one or the other working valve to an examination of the switching function of the one or the other working valve.

Abstract: A fluid control system for security relevant control and a fluid control actuator, a local control means for a fluid control system, a software module for a local control means of a fluid control system and a method for the operation of a fluid control system. The fluid control actuator (10) is controlled by control instrumentality means (30) of a local control means (50). A sensor (16, 17, 27, 41 and 42) transfers information concerning operational states of the fluid control system to the local control means (50). For this purpose there is a provision such that the local control means (50) determines from such information whether there is a security relevant situation and if necessary performs a predetermined function. The security relevant functions are integrated in the fluid control system so that same is able to be employed as prefabricated unit.
