    Abstract: An optical receiver includes a detector and frame synchronizer. The detector receives an optical OFDM bit stream having a plurality of frames. Each frame has an in-phase and quadrature phase component. Each component has an OFDM symbol-bearing data payload and a synchronization header. The synchronization header includes a single synchronization pulse. The frame synchronizer detects the synchronization header on each phase component. The frame synchronizer includes first and second pairs of digital comparators for each of the in-phase and quadrature phase components. The first and second pairs of digital comparators associated with each phase component establishes different and adjustable threshold windows that is symmetric about a zero amplitude of the synchronization pulse of the respective phase component. Each frame is synchronized when the synchronization pulse respectively associated therewith is detected as having an amplitude extending beyond at least one of the windows established for one of the phase components.

    Abstract: Triazabutadiene molecules as cleavable cross-linkers adapted to cross-link components with click chemistry, e.g., clickable triazabutadienes. For example, in some embodiments, the triazabutadienes feature alkyne handles attached to the imidazole portion or the aryl portion of the triazabutadienes, wherein the alkyne handles can link to azide handles (e.g., azide handles disposed on other components) via click chemistry. Also described are methods of producing said clickable triazabutadienes and methods of use of said clickable triazabutadienes. The present invention also features methods of cleaving said clickable triazabutadienes, e.g., for liberating the diazonium species for further chemical reactions.

    Abstract: Various examples of methods and systems are provided for real-time signal processing. In one example, a method for processing data to select a pattern includes receiving data via a sensor, evaluating the data including waveforms over a time domain, averaging the waveforms to obtain a mean waveform, selecting a pattern based on the mean waveform, and generating a notification regarding the selected pattern. The pattern can include a start time, a hold time, and an end time. In another example, a system includes one or more sensors that detect the data and a mobile platform that evaluates the data, averages the waveforms to obtain the mean waveform and selects a pattern based on the mean waveform. A user interface can be used to communicate the notification regarding the selected pattern. The patterns can include breathing patterns, which can be used to reduce stress in a subject being monitored by the sensor.
