  • Publication number: 20170133946
    Abstract: Provided is a method for controlling operation of semiconductor gates in a power conversion system including one or more multilevel inverters coupleable to a modulator and a controller. The method includes generating, via the controller, a control signal responsive to an output current power factor associated with the inverters and producing a discontinuous pulse width modulation reference signal based upon the control signal and a target output power, the discontinuous pulse width modulation reference signal being indicative of shifting a phase angle between current and voltage. A gating signal is generated for output from the modulator, as a function of the reference signal and a carrier waveform. The gating signal adjusts the phase angle to prevent switching of the semiconductor gates.

  • Publication number: 20160074373
    Abstract: Compositions and methods concern organic molecules that bind to human Atox1 and CCS at the copper trafficking interface of these proteins. This binding suppresses copper trafficking, which leads to inhibition of cancer cell proliferation and tumor growth. In addition to serving as an effective treatment of cancer, these organic molecules inhibit cellular copper uptake and can be used as treatment of disorders of copper metabolism such as Wilson's disease, which is characterized by copper overload, as well as wound healing.

  • Publication number: 20150229563
    Abstract: The present invention discloses a packet forwarding method and a network access device, where a forwarding module is added between WIFI controllers and USB controllers in an original architecture forwarding process. This module is implemented by hardware, has a forwarding entry, parses a packet according to a standard TCP/IP protocol, and then performs operations or actions such as editing, copying, discarding, and forwarding on the packet. Content of the forwarding entry is learnt by a Linux network protocol stack from an initial packet sent by the WIFI controller or the USB controller, and then a related rule is configured in the forwarding module; then, a subsequent packet from the WIFI controller or the USB controller is directly forwarded by the forwarding module. This packet forwarding method improves forwarding performance compared with the prior art.
