  • Patent number: 11538269
    Abstract: An optical fingerprint sensor (OFPS) for use with a liquid-crystal display (LCD) panel having a backlight module is positioned under the backlight module and captures an image of a fingerprint sensing area on the LCD panel through an aperture in both a reflector and a metal shield of the backlight module. The OFPS includes a sensor layer, a wafer-level optic layer bonded to the sensor layer and an infrared pass filter (IRPF) coating formed on a substantially flat top surface of the wafer-level optic layer. An OFPS may be formed with a flat top and may include a wafer-level optic layer having one or more lenses to direct light generated by a light source beneath the wafer-level optic layer. The wafer-level lenses may be bonded with the fingerprint scanner. The flat top of the OFPS may be made with an IRPF coating.

  • Patent number: 11531077
    Abstract: The cooling component may include a coolant pipeline component and a load-bearing component. The coolant pipeline component may include multiple flexible coolant pipelines with high thermal conductivity arranged side by side, the multiple coolant pipelines arranged side by side being securely arranged on the load-bearing component in such a way that a coolant liquid intake pipe and liquid output pipe are arranged uniformly in parallel in a serpentine layout without crossing over each other; so that the multiple coolant pipelines can be installed in a close fit with a Z coil of a gradient coil in such a way as to be orthogonal to the Z coil. Aspects of the present disclosure advantageously increase the support roundness of a cooling layer, and further ensure the magnetic field homogeneity of a coil supported thereby.

  • Patent number: 11521592
    Abstract: WaveFlow is a small-footprint generative flow for raw audio, which may be directly trained with maximum likelihood. WaveFlow handles the long-range structure of waveform with a dilated two-dimensional (2D) convolutional architecture, while modeling the local variations using expressive autoregressive functions. WaveFlow may provide a unified view of likelihood-based models for raw audio, including WaveNet and WaveGlow, which may be considered special cases. It generates high-fidelity speech, while synthesizing several orders of magnitude faster than existing systems since it uses only a few sequential steps to generate relatively long waveforms. WaveFlow significantly reduces the likelihood gap that has existed between autoregressive models and flow-based models for efficient synthesis. Its small footprint with 5.91M parameters makes it 15 times smaller than some existing models. WaveFlow can generate 22.05 kHz high-fidelity audio 42.

  • Patent number: 11482207
    Abstract: Described herein are embodiments of an end-to-end text-to-speech (TTS) system with parallel wave generation. In one or more embodiments, a Gaussian inverse autoregressive flow is distilled from an autoregressive WaveNet by minimizing a novel regularized Kullback-Leibler (KL) divergence between their highly-peaked output distributions. Embodiments of the methodology computes the KL divergence in a closed-form, which simplifies the training process and provides very efficient distillation. Embodiments of a novel text-to-wave neural architecture for speech synthesis are also described, which are fully convolutional and enable fast end-to-end training from scratch. These embodiments significantly outperform the previous pipeline that connects a text-to-spectrogram model to a separately trained WaveNet. Also, a parallel waveform synthesizer embodiment conditioned on the hidden representation in an embodiment of this end-to-end model were successfully distilled.

  • Publication number: 20220108712
    Abstract: Developed and presented herein are embodiments of a new end-to-end approach for audio denoising, from a synthesis perspective. Instead of explicitly modelling the noise component in the input signal, embodiments directly synthesize the denoised audio from a generative model (or vocoder), as in text-to-speech systems. In one or more embodiments, to generate the phonetic contents for the autoregressive generative model, it is learned via a variational autoencoder with discrete latent representations. Furthermore, in one or more embodiments, a new matching loss is presented for the denoising purpose, which is masked on when the corresponding latent codes differ. As compared against other method on test datasets, embodiments achieve competitive performance and can be trained from scratch.
