  • Publication number: 20230158038
    Abstract: A method for treating an influenza virus infection is described. The disclosed method generally involves administering an effective amount of a compound, for example baloxavir marboxil, to a subject having an influenza virus infection and at least one complication risk factor. Generally, the amount is effective such that a reduction in a time to improvement of at leat one symptom of an influenza virus infection is statistically significant as compared to that of a non-treated subject.

  • Patent number: 10991335
    Abstract: A display device according to the present disclosure includes: pixels arranged in a matrix; a data line group that includes a pair of data lines for each pixel column; a data line drive circuit that supplies a positive-phase data signal to one of the pair of data lines, and a negative-phase data signal to the other of the pair of data lines; and an auxiliary drive circuit that is provided for each pair of data lines, and that processes the positive-phase data signal and the negative-phase data signal, in which the auxiliary drive circuit has a dead zone in a region where there is no difference between a positive-phase potential and a negative-phase potential, or where the difference in potential is smaller than a predetermined value. An electronic apparatus according to the present disclosure includes a display device having the configuration described above.

  • Patent number: 9747857
    Abstract: A display device includes: data-line pairs arranged side by side along a first direction; gate lines arranged side by side along a second direction; a display section including pixels each disposed at an intersection of a data-line pair and a gate line and connected to one or both of the data-line pair; a data-line drive circuit supplying a positive-phase data signal to one of the data-line pair and a negative-phase data signal to the other, and allowing the data-line pair to stay in a high-impedance state before writing of an image signal to the pixels; and a short circuit putting the data-line pair in a short-circuit state while the data-line pair stays in the high-impedance state, and then releasing the short-circuit state Following the release of the short-circuit state, the positive-phase data signal or/and the negative-phase data signal are written into the pixel as the image signal.

  • Patent number: 8139015
    Abstract: An amplification circuit includes: an amplifier apparatus configured to amplify an input signal and outputting the amplified signal from an output terminal; and a boost circuit which, when a difference between a voltage of the input signal and a voltage at the output terminal is greater than a given value, supplies a positive or negative constant electrical current to at least one given part of the amplifier apparatus, thus enhancing output responsiveness of the amplifier apparatus.
