  • Publication number: 20220116088
    Abstract: A first device and second device communicate using mmWave communication with antenna alignment based on processing of ultra wide band (UWB) pulses. A limit on angle resolution due to a small number of antennas on either of the devices is relieved by using two or more carrier frequencies in the UWB pulses. A limit on angle resolution is further overcome in some situations by use of a neural network to refine angle estimates. In some situations, received power values are further used to select an angle for beam alignment.

  • Publication number: 20220115693
    Abstract: A method for manufacturing an improved thin film composite solid electrolyte is provided. The method includes spray coating an aqueous suspension of ceramic particles onto a substrate to form a ceramic thin film. The film is sintered to form a porous ceramic structure having an interconnected necked morphology that defines cavities. The cavities are backfilled with an polymer electrolyte, for example a crosslinkable poly(ethylene oxide) (PEO)-based polymer electrolyte. The resulting thin film composite solid electrolyte is highly ionically conductive and mechanically robust with good manufacturability, particularly suitable for, but not limited to lithium metal batteries. The present method represents a departure from conventional mixing-then-casting methods and instead includes the fabrication of a solid electrolyte having a high ceramic volume fraction, high ionic conductivity, low thickness, and good chemical stability with metallic lithium.

  • Patent number: 11302312
    Abstract: A new model is introduced into a particular domain that receives a routing of a dialog from a speech processing component. A method associated with the model includes running a set of test utterances through the speech processing component that enables a spoken language dialog with a user to establish a base line score associated with processing for the set of test utterances. The speech processing component determines an intent of the user and routes the spoken language dialog to a network-based domain based on the intent. The method includes establishing an automatic test run of the set of test utterances to obtain a current score and, when a threshold associated with a difference between the current score and the base line score is breached, switching, at the network-based domain, from the false accept detection model to a second model.
