    Abstract: Systems and methods for the application of surface normal calculations are illustrated. One embodiment includes a system for navigation, including: a processor; and instructions stored in a memory that when executed by the processor direct the processor. The processor obtains a set of sensor data, wherein sensor data includes a plurality of polarized images. The processor retrieves at least one navigation query; and a plurality of key-value pairs based on the polarized images. The processor inputs the at least one navigation query and the plurality of key-value pairs into a Cross-Attention Transformer that provides a set of weighted sums, wherein each weighted sum corresponds to: a certain key-value pair from the plurality of key-value pairs; and a certain sensor. The processor updates a model based on the set of weighted sums. The processor navigates the system within a 3D environment according, at least in part, to the model.

  • Publication number: 20250021712
    Abstract: Systems and techniques performing autonomous navigation are illustrated. One embodiment includes a method for navigation. The method inputs a set of sensor data obtained from a plurality of sensors into at least one convolutional neural network (CNN). The at least one CNN generates a plurality of key-value pairs where each the key-value pair corresponds to an individual sensor from the plurality of sensors; and a value included in the key-value pair is determined based upon a subset of sensor data obtained from the individual sensor. The method inputs at least one navigation query and the plurality of key-value pairs into a Cross-Attention Transformer (CAT). The method obtains, from the CAT, a set of weighted sums, wherein each weighted sum corresponds to: a certain key-value pair; and a certain sensor from the plurality of sensors. The method updates a model depicting a 3D environment based on the set of weighted sums.

  • Patent number: 9709734
    Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical coupler. In some embodiments, the device may include an optical waveguide to transmit light input from a light source. The optical waveguide may include a semiconductor layer, having a trench with one facet that comprises an edge formed under an approximately 45 degree angle and another facet formed substantially normal to the semiconductor layer. The edge may interface with another medium to form a mirror to receive inputted light and reflect received light substantially perpendicularly to propagate the received light. Other embodiments may be described and/or claimed.

  • Patent number: 9658396
    Abstract: Described herein are an apparatus, system, and method for providing a vertical optical coupler (VOC) for planar photonics circuits such as photonics circuits fabricated on silicon-on-insulator (SOI) wafers. In one embodiment, the VOC comprises a waveguide made from a material having refractive index in a range of 1.45 to 3.45, the waveguide comprising: a first end configured to reflect light nearly vertical by total internal reflection between the waveguide and another medium, a second end to receive the light for reflection, and a third end to output the reflected light. The VOC couples with a Si waveguide having a first region including: a first end to receive light; and an inverted tapered end in the direction of light propagation to output the received light, wherein the inverted tapered end of the Si waveguide is positioned inside the waveguide.

  • Patent number: 9395494
    Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical device having a semiconductor layer to propagate light and a mirror disposed inside the semiconductor layer and having echelle grating reflective surface to substantially totally internally reflect the propagating light inputted by one or more input waveguides, to be received by one or more output waveguides. The waveguides may be disposed in the semiconductor layer under a determined angle relative to the mirror reflective surface. The determined angle may be equal to or greater than a total internal reflection angle corresponding to the interface, to provide substantially total internal reflection of light by the mirror. The mirror may be formed by an interface of the semiconductor layer comprising the mirror reflective surface and another medium filling the mirror, such as a dielectric. Other embodiments may be described and/or claimed.
