  • Patent number: 11246230
    Abstract: Configurable smart object systems with methods of making modules and contactors are provided. Example systems implement machine learning based on neural networks that draw low power for use in smart phones, watches, drones, automobiles, and medical devices. Example assemblies can be configured from pluggable, interchangeable modules that have compatible ports for interconnecting and integrating functionally dissimilar sensor systems. An example method includes mounting an element of a configurable machine learning assembly on a substrate, creating at least one fold in the substrate, folding the substrate at the fold into a housing of a module of the configurable machine learning assembly, and adding a molding material to the housing to at least partially fill the module of the configurable machine learning assembly. The example module construction may also form contactors on folded edges of the module for making physical and electrical contact with other modules of the smart object machine learning assembly.

  • Patent number: 11239587
    Abstract: Configurable smart object systems with grid or frame-based connectors are provided. Example systems implement machine learning based on neural networks that draw low power for use in smart phones, watches, drones, automobiles, and medical devices, for example. Example assemblies can be configured from pluggable, interchangeable modules that have compatible ports with magnetic electrical contacts for interconnecting and integrating functionally dissimilar sensor systems. An example system has a clip attachable to a substrate for securing a smart object module to the substrate, and a housing of the clip with a geometry for aligning electrical contacts of the smart object module with electrical contacts of the substrate. The clip may have a compliant layer to provide spring, resilience, or pressure to securing the smart object module to the substrate. The clip may also integrate features of a secure digital (SD) port and a universal serial bus (USB) port.

  • Patent number: 11221513
    Abstract: An electronic device includes display layers such as liquid crystal display layers and a backlight unit that provides illumination for the display layers. The backlight unit includes light-emitting diodes that emit light into the edge of a light guide film. To minimize the inactive area of the display, the light-emitting diodes are tightly spaced to approximate a line light source instead of point light sources. Color and/or luminance compensation layers are incorporated at various locations within the backlight structures to ensure that the backlight provided to the display layers is homogenous. A thin-film transistor layer of the display is coupled to a printed circuit board by a flexible printed circuit. The flexible printed circuit has additional solder mask layers to improve robustness, encapsulation, and traces with a varying pitch.

  • Patent number: 10782485
    Abstract: Hardened fiber optic connectors having a mechanical splice assembly are disclosed. The mechanical splice assembly is attached to a first end of an optical waveguide such as an optical fiber of a fiber optic cable by way of a stub optical fiber, thereby connectorizing the hardened connector. In one embodiment, the hardened connector includes an inner housing having two shells for securing a tensile element of the cable and securing the mechanical splice assembly so that a ferrule assembly may translate. Further assembly of the hardened connector has the inner housing fitting into a shroud of the hardened connector. The shroud aides in mating the hardened connector with a complimentary device and the shroud may have any suitable configuration. The hardened connector may also include features for fiber buckling, sealing, cable strain relief or a pre-assembly for ease of installation.

  • Patent number: 10734759
    Abstract: Configurable smart object systems with magnetic contacts and magnetic assembly are provided. Example systems implement machine learning based on neural networks that draw low power for use in smart phones, watches, drones, automobiles, and medical devices, for example. Example assemblies can be configured from pluggable, interchangeable modules that have compatible ports with magnetic electrical contacts for interconnecting and integrating functionally dissimilar sensor systems. The magnetic electrical contacts physically couple the interfaces together or to a motherboard socket while providing an electrical coupling across the coupled magnetic contacts. The magnetic electrical contacts may arrayed in a reversible configuration so that a module or plug connection is reversible. A controller may dynamically assign power, ground, and data channels to the magnetic electrical contacts on the fly as the system is configured or reconfigured.
