Abstract: A method for detecting a hotword includes receiving a sequence of input frames that characterize streaming audio captured by a user device and generating a probability score indicating a presence of a hotword in the streaming audio using a memorized neural network. The network includes sequentially-stacked single value decomposition filter (SVDF) layers and each SVDF layer includes at least one neuron. Each neuron includes a respective memory component, a first stage configured to perform filtering on audio features of each input frame individually and output to the memory component, and a second stage configured to perform filtering on all the filtered audio features residing in the respective memory component. The method also includes determining whether the probability score satisfies a hotword detection threshold and initiating a wake-up process on the user device for processing additional terms.

Abstract: The present invention relates to a self-humidifying ion-exchange composite membrane including an aromatic hydrocarbon polymer ion-exchange membrane formed on the surface of a porous polymer support and a thin hydrophobic coating layer having a nanocracked morphology pattern on the surface of the ion-exchange membrane. The self-humidifying ion-exchange composite membrane of the present invention has good thermal/chemical stability, high mechanical strength, high ion-exchange capacity, and good long-term operational stability. Particularly, the self-humidifying ion-exchange composite membrane of the present invention is able to self-hydrate even under high-temperature and low-humidity conditions. Due to these advantages, it is expected that the self-humidifying ion-exchange composite membrane of the present invention will be commercialized as an electrolyte membrane for a fuel cell or a membrane for water treatment.

Abstract: This disclosure describes circuit configurations that may be used for active noise cancellation in the digital domain. In particular, this disclosure proposes the use a down sample unit and an up sample unit, rather than memory-based delay circuits, to achieve one or more desired delays in digital adaptive noise cancellation circuits or other circuits that use delay for signal processing. The delay achieved by the down sample unit and the up sample unit may be tunable so as to allow flexibility in producing the necessary delay for different active noise cancellation circuit configurations. Many different adaptive noise cancellation circuit configurations are discussed, and the techniques may also be useful for other types of circuits, such as low-latency equalization circuits.
