Abstract: Disclosed herein are two-wire communication systems and applications thereof. In some embodiments, a slave node transceiver for low latency communication may include upstream transceiver circuitry to receive a first signal transmitted over a two-wire bus from an upstream device and to provide a second signal over the two-wire bus to the upstream device; downstream transceiver circuitry to provide a third signal downstream over the two-wire bus toward a downstream device and to receive a fourth signal over the two-wire bus from the downstream device; and clock circuitry to generate a clock signal at the slave node transceiver based on a preamble of a synchronization control frame in the first signal, wherein timing of the receipt and provision of signals over the two-wire bus by the node transceiver is based on the clock signal.

Abstract: There is disclosed in one example an audio processor, including: an audio crossover to separate a first frequency band from a second frequency band, the first frequency band having a lower frequency band than the second frequency band; an excursion estimator to estimate from information of the first frequency band a predicted excursion of a low-frequency driver; an interpolator to interpolate an adjustment to the second frequency band to compensate for the estimated excursion; and circuitry to drive the adjusted second frequency to a receiver.

Abstract: Systems and methods for optically measuring displacement of an element include an emitter for emitting an optical signal, a first detector for detecting reflections of the optical signal from the element, a second detector for detecting reflections of the optical signal from a raised cover structure, a processor for receiving the detected reflections from the first and second detectors and removing distortions in the detected reflections from the first detector using the detected reflections from the second detector.

Abstract: Speakers do not always operate linearly. Linearity of the speaker can affect the quality of the sound produced by the speaker, i.e., causing distortions in the sound, if the nonlinearites are not accounted for. To determine nonlinearities of the speaker, the speaker is often modeled and measurements are made to estimate the characteristics of the speaker based on the model. By using an angle sensor and a light source, a speaker manager can make a direct measurement of excursion or displacement of the speaker. Moreover, when the angle sensor, the light source, and the light beam are configured appropriately with respect to the moving cone of the speaker, the measurement can be substantially linear with respect to the amount of excursion or displacement. Such measurements are far simpler to use and in some cases more accurate than measurements made by other types of systems.
