Abstract: Techniques for implementing and/or operating an electronic device including a display pixel layer, which writes a display image during an active period and continues displaying the display image during a blanking period, and a touch sense layer, which generates a first touch image during the active period and a second touch image during the blanking period. The electronic device further includes a controller that determines a first noise metric indicative of display-to-touch noise resulting during the active period based on the first touch image, determines a second noise metric indicative of display-to-touch noise resulting during the blanking period based on the second touch image, and instructs the touch sense layer to not generate a third touch image during a subsequent active period in response to the first noise metric being greater than a noise threshold and the second noise metric not being greater than the noise threshold.

Abstract: The present disclosure provides an article. In an embodiment, the article includes a substrate and a coating on the substrate. The coating includes a composition. The composition includes a plurality of nanoparticles, each nanoparticle having a ligand linked to a surface of each nanoparticle. The composition includes a plurality of block copolymers. Each block copolymer includes a linking block and a nonlinking block. The linking block is a random copolymer composed of at least two different monomers. At least one of the monomers is a linking comonomer. The linking comonomer is directly linked to the ligand to form a first microdomain consisting of the linking block, the nanoparticles, and the ligand. The composition further includes a second microdomain consisting of the nonlinking block.

Abstract: Systems and methods reduce likelihood of hysteresis that reduces perceived image quality of a subsequent image frame by toggling the display pixels to relax the display pixels by overwriting previous image frame data. During non-emission periods of the pixels, the pixels may be pre-toggled or exercised to improve response time and accuracy of the pixel. Data for pixels being programmed may also be used to pre-toggle other pixels reducing overhead but increasing cross-talk. Since the amount of cross-talk is related to content of the pixels being pre-toggled, a line buffer may be used to store image data for the pixels being pre-toggled. This stored image data may be used to determine how much pre-compensation is to be applied to data for the pixels being programmed. In other words, an amount of compensation applied is based at least in part on the content (e.g., greyscale levels) of the image data.

Abstract: Display-to-touch noise may be perceptible when a touch image generated during an active period of an electronic display of an electronic device is used to determine a touch indication on the display. The electronic device may include a display pixel layer including a plurality of display pixels that write display images to the display during a display active period and continue displaying the display image during a display blanking period. The electronic device may also include a touch sense layer including a plurality of touch sense pixels that facilitate generation of a first touch image during a first display active period and generation of a second touch image during a first display blanking period. The electronic device may further include a controller coupled to the display pixel layer and the touch sense layer that facilitates the reduction or elimination of display-to-touch interference.

Abstract: An apparatus includes a first squelch circuit and a second squelch circuit. The first squelch circuit is configured to detect possible squelch signals in a communication signal. The second squelch circuit is configured to selectively detect the possible squelch signals in the same communication signal. The second squelch circuit is further configured to operate in a low-power state responsive to the first squelch circuit detecting none of the possible squelch signals in the communication signal. The second squelch circuit is further configured to operate in a high-power state responsive to the first squelch circuit detecting one of the possible squelch signals in the communication signal.

Abstract: The present invention provides a travelway structure for maglev transportation comprises: a travelway girder having a concrete girder plate extending from two sides of the travelway girder; a pre-embedded member pre-embedded in the concrete girder plate; and a detachable member installed on the pre-embedded member via a fastener, wherein the pre-embedded member is machinable, and a position for installing the detachable member on the pre-embedded member is formed by a machining process after the travelway girder experiences deformations which lead to errors. A method for manufacturing a travelway structure for maglev transportation is also provided according to the present invention. Specifically, after a period of time, during which the travelway girder experiences most of the deformations caused by pre-stressed tension and gradual contraction and the like, the travelway girder along with the pre-embedded pieces are moved to the machine tools for machining the functional pre-embedded member.
