  • Patent number: 9946381
    Abstract: A driving method for a liquid crystal panel is disclosed. Wherein, the driving method includes: (A) at a moment of switching from a normal display time stage to a touch scanning time stage in a current frame, applying a first over driving voltage to a common electrode of each pixel of a liquid crystal panel; and (B) at a moment of switching from the touch scanning time stage in the current frame to a normal display time stage of a next frame, applying a second over driving voltage to the common electrode of each pixel. According to the method described above a time that the common electrode reaches a present level voltage is shorten in order to effectively improve the poor display and touch problem caused by signal abnormality at moments of switching between a normal display and a touch scanning in an in-cell touch panel.

  • Patent number: 9918085
    Abstract: An improved loss recovery method for coding streaming media classifies each data unit in the media stream as an independent data unit (I unit), a remotely predicted unit (R unit) or a predicted data unit (P unit). Each of these units is organized into independent segments having an I unit, multiple P units and R units interspersed among the P units. The beginning of each segment is the start of a random access point, while each R unit provides a loss recovery point that can be placed independently of the I unit. This approach separates the random access point from the loss recovery points provided by the R units, and makes the stream more impervious to data losses without substantially impacting coding efficiency. The most important data units are transmitted with the most reliability to ensure that the majority of the data received by the client is usable. The I units are the least sensitive to transmission losses because they are coded using only their own data.

  • Patent number: 9911575
    Abstract: A charged particle multi-beam lithography system includes an illumination sub-system that is configured to generate a charged particle beam; and multiple plates with a first aperture through the plates. The plates and the first aperture are configured to form a charged particle doublet. The system further includes a blanker having a second aperture whose footprint is smaller than that of the first aperture. The charged particle doublet is configured to demagnify a portion of the charged particle beam passing through the first aperture, thereby producing a demagnified beamlet. The blanker is configured to receive the demagnified beamlet from the charged particle doublet, and is further configured to conditionally allow the demagnified beamlet to travel along a desired path.
