  • Patent number: 11562744
    Abstract: In one embodiment, a method includes receiving a voice input from a user and determining a first style of the voice input, based on first features extracted from the voice input. A second style for a voice response having second features may then be determined based on the first style. Finally, the voice response may be generated based on the second features of the second style, and this voice response may be provided in response to the voice input.

  • Patent number: 11474133
    Abstract: It is disclosed an insulation impedance detection circuit and detection method of a photovoltaic inverter system. The photovoltaic inverter system includes one or more input circuits and an inverter circuit, each of the input circuit electrically coupled to the inverter circuit through a positive bus and a negative bus, with a first equivalent impedance Rp between the positive bus and a protective earth point and a second equivalent impedance Rn between the negative bus and the protective earth point. The detection circuit includes: a bus voltage sampling circuit coupled to the positive bus and the negative bus for generating a first bus voltage and a second bus voltage; a protective earth voltage sampling circuit coupled to the protective earth point for generating a first protective earth voltage and a second protective earth voltage; and a controller for calculating an equivalent insulation impedance.

  • Patent number: 9213794
    Abstract: A system and method for routing a buffered interconnect in an IC from a source cell to a target cell thereof. In one embodiment, the system includes: (1) a path tracer operable to designate the source cell as a current node and construct a path toward the target node by: (1a) defining a boundary about the current node based on a buffer driving length, (1b) trimming the boundary by any blockage therein to yield a candidate area for placing a buffer, (1c) dividing the boundary into line segments, (1d) selecting a closest, valid one of the line segments to the target cell as the current node and (1e) repeating the defining, trimming, dividing and selecting the closest, valid one until the current node lies within the buffer driving length and (2) a buffer placer associated with the path tracer and operable to select a location along the path to place the buffer.
