  • Patent number: 10333422
    Abstract: A power supply circuit includes a rectifier module configured to rectify an input voltage and a capacitor including a first terminal coupled to the rectifier module. In addition, the power supply circuit includes first and second transistors. The first transistor couples to a second terminal of the capacitor, and the second transistor couples in series to the first transistor. The power supply circuit also includes a resistor, configured to set an inrush current value, in parallel with the second transistor. When coupled to a power supply, the power supply circuit is configured to turn-on the first transistor such that an inrush current flows, at the inrush current value, through the capacitor, first transistor, and resistor. After a delay time, the power supply circuit is configured to turn-on the second transistor such that the inrush current drops to around zero, thus maintaining a low impedance path during steady-state operation.

  • Patent number: 10331599
    Abstract: Session level restrictions can be implemented to limit access to a redirected interface of a composite device. These session level restrictions can be defined within a policy of a directory service, such as Active Directory, to facilitate the dynamic application of the restrictions to the appropriate remote sessions. In this way, access restrictions can be applied to individual interfaces of a redirected composite device so that a particular interface will only be accessible from specified remote sessions.

A frequency domain simulation is performed over different frequencies using each of the variables to provide simulated frequency domain responses for the simulated system. A time domain simulation is performed over the different frequencies using a subset of simulated frequency domain responses to produce a plurality of simulated time domain responses for the simulated system. The subset of the simulated frequency domain responses is mapped to the plurality of simulated time domain responses to produce a frequency-domain-to-time-domain mapping. A plurality of mapped time domain responses is determined using the frequency-domain-to-time-domain mapping, where the plurality of simulated time domain responses and the plurality of mapped time domain responses provide time domain responses for each of the plurality of variables for the simulated system.
