  • Publication number: 20190016909
    Abstract: A method for fabricating nanostructured polymeric materials based on a combination of inkjet printing and template synthesis. Layer-by-layer assembled nanotubes can be synthesized in a polycarbonate track-etched (PCTE) membrane by printing poly(allylamine hydrochloride) (PAH) and poly(styrenesulfonate) (PSS) sequentially. By changing the printing conditions, polymeric nanotubes or nanowires can be prepared by printing poly(vinyl alcohol) (PVA) in a PCTE template. Inkjet printing paired with template synthesis can be used to generate patterns comprised of chemically distinct nanomaterials. Thin polymeric films of layer-by-layer assembled PAH and PSS can be printed on a PCTE membrane. Inkjet printing paired with template synthesis can also be used to prepare functional mosaic membranes, such as charge mosaic membranes comprising polyelectrolytes of different charges to pattern positively charged or negatively-charged domains, respectively, on the surface of the template.

    Abstract: A method for controlling a digital fractional frequency-division phase-locked loop and a phase-locked loop are disclosed. The phase-locked loop includes a control apparatus, a TDC, a DLF, a DCO, a DIV, and an SDM. The control apparatus performs delay processing on an active edge of a reference clock according to a frequency control word and a frequency division control word to obtain a delayed reference clock; and sends the delayed reference clock to the TDC so that the TDC performs phase discrimination processing on the delayed reference clock and a feedback clock. A control apparatus added to a phase-locked loop may perform delay processing on a reference clock according to a current frequency control word and a current frequency division control word, so that a feedback clock and a delayed reference clock have active edges that approximately correspond in time.

  • Publication number: 20180186009
    Abstract: A robot voice direction-seeking turning system and method. The robot voice direction-seeking turning system employs a voice activity detection unit (1) that detects a received voice signal to determine whether or not a voice signal transmitted by a user (S2) is present; a direction-seeking angle for the voice signal is calculated by a voice direction-seeking unit (3), and a voice direction-seeking turning unit (4) is employed to drive a robot to turn towards the direction of the sound source of the voice signal on the basis of a direction-seeking angle (S4). Employment of the robot voice direction-seeking turning method allows accurate acquisition of a valid voice signal transmitted by the user, thus increasing signal-to-noise ratio and the accuracy of voice recognition.
