An output grating for waveguide of a head-mounted display is configured to suppress the (1, 1) diffraction order of the output grating. The grating has a design of two or more materials having different refractive indices. The design is repeated periodically in a first dimension and repeated periodically in a second dimension, to form a two-dimensional pattern. A refractive index of the two-dimensional pattern is approximated by a two-dimensional Fourier series comprising a first coefficient of order (1, 0), a second coefficient of order (0, 1), and a third coefficient of order (1, 1). The third coefficient is less than half the first coefficient and less than half the second coefficient, such that light from the (1, 1) diffraction order of the grating is suppressed.

A display waveguide is configured to direct a first portion of display light to an eye along a first optical path. A disparity waveguide is configured to direct a second portion of the display light to a disparity sense circuit along a second optical path separated from the first optical path.

An optical assembly to be used in a head-mounted display (HMD) device or similar may include a first optical component and a second optical component, where the first optical component and the second optical component are layered in the optical assembly. The optical assembly may also include a waveguide positioned between the first optical component and the second optical component. One or more shock absorbers may be positioned on surfaces of the first optical component and the second optical component facing the waveguide. The shock absorbers may be a support that touches a surface of the waveguide or a stand-off that extends toward the waveguide with a gap. The shock absorbers may also include a pillar, a cone, an inverted cone, an inverted pillar, a spring, a double helix, a three-dimensional mesh, a strap, a bumper, a sphere, or a high aspect ratio 3D mesh tower.

A waveguide is provided. The waveguide includes a substrate having two outer surfaces for propagating a beam of light in the substrate by reflecting the beam from the two outer surfaces. The waveguide includes at least one polarization volume hologram (PVH) grating to couple light in and/or out of the waveguide. The PVH grating may be a multi-layer PVH grating with graded birefringence.

A near-eye optical assembly includes a display waveguide and an optical structure. The display waveguide is configured to receive display light and to direct the display light to an eye of a user. The optical structure includes an input coupler, an optical path, and an output coupler. The input coupler is disposed to receive a portion of the display light that propagates through the waveguide. The optical path directs the portion of the display light from the input coupler to an output coupler that is configured to provide the received portion of the display light to a disparity sense circuit.

A transcription of audio speech included in electronic content associated with a meeting is created by an ASR model trained on speech-to-text data. The transcription is post-processed by modifying text included in the transcription, for example, by modifying punctuation, grammar, or formatting introduced by the ASR model and by changing or omitting one or more words that were included in both the audio speech and the transcription. After the transcription is post-processed, output based on the post-processed transcription is generated in the form of a meeting summary and/or template.

An apparatus includes a substrate, at least one type of tuning material, and a composite material. The substrate has an interface surface or material that manifests, in response to light in a color spectrum, a particular color and a first thermal load. The particular color is associated with the first thermal load. The at least one type of tuning material manifests, in response to light in the color spectrum, the particular color and a second thermal load. The particular color is associated with the second thermal load. The first thermal load is different from the second thermal load. The composite material includes the interface surface or material and the at least one type of tuning material. The composite material manifests, in response to light in the color spectrum, the particular color and a tuned thermal load which is different than the first thermal load and the second thermal load.

An example intent-recognition system comprises a processor and memory storing instructions. The instructions cause the processor to receive speech input comprising spoken words. The instructions cause the processor to generate text results based on the speech input and generate acoustic feature annotations based on the speech input. The instructions also cause the processor to apply an intent model to the text result and the acoustic feature annotations to recognize an intent based on the speech input. An example system for adapting an emotional text-to-speech model comprises a processor and memory. The memory stores instructions that cause the processor to receive training examples comprising speech input and receive labelling data comprising emotion information associated with the speech input. The instructions also cause the processor to extract audio signal vectors from the training examples and generate an emotion-adapted voice font model based on the audio signal vectors and the labelling data.

A waveguide display includes a waveguide, an input coupler configured to couple display light into the waveguide, and a surface-relief grating on the waveguide and configured to couple the display light out of the waveguide towards an eyebox of the waveguide display on a first side of the waveguide. The surface-relief grating is formed in a plurality of grating layers having uniform or non-uniform thickness profiles. The plurality of grating layers is characterized by a refractive index modulation that increases and then decreases as the distance of the grating layer from the waveguide increases.

Embodiments of the present disclosure relate generally to determining node embedding using multi-view graphs for analyzing electronic content.

Node embedding in multi-view feature vectors

A diffraction grating includes a substrate and a plurality of fringes supported by the substrate. The fringes run parallel to each other in a first direction. A refractive index of a material of the plurality of fringes is anisotropic, whereby a refractive index contrast of the diffraction grating depends on direction of electric field of an impinging light beam, and through that dependence is a function of an azimuthal angle of the impinging light beam. A dependence of the diffraction efficiency on the azimuthal angle is affected by the dependence of the refractive index contrast on the direction of electric field of an impinging light beam. A pupil-replicating waveguide may use such a diffraction grating as a coupler for in- our out-coupling image light.

Anisotropic diffraction grating and waveguide

The present disclosure provides method and apparatus for processing a message. A statement sentence message and a message processing parameter associated with a user's session message are obtained. One or more first statement sentence nodes that are semantic-matched with the statement sentence message are determined in the knowledge map. One or more second statement sentence nodes corresponding to the message processing parameters are obtained from the knowledge map, based on the node relationship properties of the first statement sentence nodes. A response is generated based at least in part on statement sentences of the one or more second statement sentence nodes. The generated response is provided to the user.
