  • Patent number: 11916200
    Abstract: The disclosure herein relates to rechargeable batteries and solid electrolytes therefore which include lithium-stuffed garnet oxides, for example, in a thin film, pellet, or monolith format wherein the density of defects at a surface or surfaces of the solid electrolyte is less than the density of defects in the bulk. In certain disclosed embodiments, the solid-state anolyte, electrolyte, and catholyte thin films, separators, and monoliths consist essentially of an oxide that conducts Li+ ions. In some examples, the disclosure herein presents new and useful solid electrolytes for solid-state or partially solid-state batteries. In some examples, the disclosure presents new lithium-stuffed garnet solid electrolytes and rechargeable batteries which include these electrolytes as separators between a cathode and a lithium metal anode.

  • Patent number: 11915493
    Abstract: A deep neural network(s) (DNN) may be used to detect objects from sensor data of a three dimensional (3D) environment. For example, a multi-view perception DNN may include multiple constituent DNNs or stages chained together that sequentially process different views of the 3D environment. An example DNN may include a first stage that performs class segmentation in a first view (e.g., perspective view) and a second stage that performs class segmentation and/or regresses instance geometry in a second view (e.g., top-down). The DNN outputs may be processed to generate 2D and/or 3D bounding boxes and class labels for detected objects in the 3D environment. As such, the techniques described herein may be used to detect and classify animate objects and/or parts of an environment, and these detections and classifications may be provided to an autonomous vehicle drive stack to enable safe planning and control of the autonomous vehicle.

  • Patent number: 11886686
    Abstract: A user interface, system and method for optimizing a patient problem list in an electronic medical record or electronic health record in which entries in the problem list are removable or otherwise editable if they were entered into the problem list longer ago than a limited duration window to which the entries are categorized. In order to determine that categorization, the problem list entries are mapped to concepts or lexicals of an interface terminology, which in turn is mapped to concepts of another terminology, and those concepts are analyzed with respect to one or more criteria used to establish the limited duration window.

  • Patent number: 11758421
    Abstract: A mesh network includes domain(s) of multiple nodes interconnected through links and in which there are gateway(s) connecting a domain to another network. The domain(s), their multiple nodes, and their links are part of a topology. A set of primary and backup routing paths, each including an ST that includes the selected gateway and route to that selected gateway for nodes in the domain, for a selected one of the gateway(s) is accessed or determined. Schedule(s) to be used by node(s) in the mesh network over one or more scheduling cycles are accessed or determined. Based on status of link(s) between nodes and on the schedule(s), switching is performed to a selected one of the primary or backup routing paths for the selected gateway. Routing in the mesh network is caused to be modified based on the selected routing path. Information is sent to nodes for the paths and schedules.

  • Patent number: 11609974
    Abstract: This application relates to apparatus and methods for automatically determining and enforcing user permissions for applications and application features. In some embodiments, a system includes a server and a user device. The server may determine a user of the user device based on receiving login credential data. The server may further obtain user attributes for the user including, in some examples, a location of the user. The server may further obtain an attribute-based control policy that identifies relationships between a plurality of possible user attributes. For example, the control policy may identify attribute requirements that must be met for enablement of a particular application feature. Additionally, the server may determine user permissions for the user based on the control policy and the user attributes. The server may transmit the user permissions to the user device, and the user device configures the corresponding application according to the user permissions.

  • Publication number: 20230045930
    Abstract: Disclosed herein are system, method, and computer program product embodiments for machine learning systems to process incoming call-center calls based on inferred sentiments. An incoming call is routed to a call agent based on an inferred topic, classified based on one or more inferred sentiments of a current caller's speech, determining, based on the call classification, that a complaint has been articulated and initiating an automated assistance by searching for one or more similar callers to the current caller. Based on finding a successful call outcome associated with one or more similar callers, the system suggests one or more phrases to the call agent for use in a dialog with the current caller to improve the one or more inferred sentiments.

  • Publication number: 20230020558
    Abstract: A cover for covering a car or luggage on top of a car is described. The cover is made of a stretchy material such that it can expand to tightly fit the size and shape of a large variety of items or vehicles. Thus, the material composition as well as cover layers are crucial in obtaining the optimal balance of flexibility and protection. In many embodiments securing mechanisms are provided around the base of the cover as well as over the top of the cover to aid in securing the cover over the items or vehicle. In some embodiments a lower cover is provided which sits under items on top of a vehicle and protects the roof of the vehicle from the items.

  • Patent number: 11507488
    Abstract: Techniques are described for detecting faults in media content based on the behavior of users viewing the media content. Embodiments stream a first instance of media content to one or more users. The behavior of the one or more users is monitored while the users are viewing the streaming first instance of media content. Embodiments then determine whether the first instance of media content is faulty, based on the monitored behavior of the one or more users.

  • Publication number: 20220360616
    Abstract: Embodiments of the present invention are directed to a Content Delivery Network (CDN) for broadcasting data streams. The CDN allows a streamer to stream live (in realtime) on a network(s), such as the Internet, for a live audience to view and to interact with the live entertainment. Each of the broadcast clients send data streams to the CDN via an input node, wherein the CDN output a selected media stream to one or more selected viewing clients via the output node. The architecture of the CDN contains one or more System Racks. Each of the System Racks contains multiple media channels. In operation, the data stream of a broadcasting client is sent to the CDN and distributed into selected channels. The data streams in each of the selected channels are outputted to viewing clients of a corresponding type.
