  • EMC control for pulsed high voltage source of a plasma device for medical treatment
    Patent number: 11558953
    Abstract: The invention relates to a high voltage source to be coupled to an electrode arrangement for a dielectric barrier discharge plasma treatment. It has a high voltage transformer device including a primary and secondary inductor coupled via a magnetic circuit. A feed circuit including a power capacitor, the power capacitor coupled with the primary inductor and a first controllable conductor in series. A controller is arranged to intermittent switching of the first controllable conductor in on- and off-states; and a second controllable conductor is coupled in parallel to the primary windings; the controller arranged to switch the second controllable conductor to a conducting on-state when the first controllable conductor is in an on-state to short the resonating current in the primary inductor.

  • INSTRUMENT, A SYSTEM AND A CONTAINER FOR PROVISIONING A DEVICE FOR PERSONAL CARE TREATMENT, AND A DEVICE FOR PERSONAL CARE TREATMENT WITH SUCH A CONTAINER
    Publication number: 20090063775
    Abstract: The present invention provides a system and a method for a cache partitioning technique for application tasks based on the scheduling information in multiprocessors. Cache partitioning is performed dynamically based on the information of the pattern of task scheduling provided by the task scheduler (405). Execution behavior of the application tasks is obtained from the task scheduler (405) and partitions are allocated (415) to only a subset of application tasks, which are going to be executed in the upcoming clock cycles. The present invention will improve the cache utilization by avoiding unnecessary reservation of the cache partitions for the executing application tasks during the entire duration of their execution and hence an effective utilization of the cache is achieved.
