  • Publication number: 20240337897
    Abstract: Disclosed is an optical pulse adjusting device including a pulse shaper that receives an input signal generated based on an optical frequency comb (OFC) signal and outputs a spectrum adjustment signal by adjusting an optical spectrum shape of the input signal, an optical amplifier that outputs an optical amplification signal by amplifying the spectrum adjustment signal, an optical spectrum analyzer (OSA) that outputs an information signal by comparing an optical spectrum shape of the optical amplification signal with a target optical spectrum shape, and a control circuit that outputs a comparison signal based on the information signal. The pulse shaper further receives the comparison signal and adjusts the optical spectrum shape of the input signal based on information about a difference between the optical spectrum shape of the optical amplification signal and the target optical spectrum shape, which is included in the comparison signal.

  • Publication number: 20230135310
    Abstract: The manufacturing of footwear includes the joining of components. The joining may be accomplished with adhesive. The adhesive, such as a polyurethane, is applied as a single-sided adhesive to a footwear component. The application of the adhesive can contaminate the system that is applying the adhesive with intentional over spray of the footwear component. The over spray ensures adequate coverage of the footwear component to allow a sufficient bond. A masking platform of the system masks portions of the system to limit the contamination caused by the over spray. Additionally, material brushes and scrapers may engage with components of the system to remove or limit adhesive contamination on those components. A vision system maps a surface of the footwear component to ensure the adhesive is applied for the specific article.
