  • Patent number: 11422568
    Abstract: An autonomous mobile device (AMD) may perform various tasks during operation. Some tasks, such as delivering a message to a particular user, may involve the AMD identifying the particular user. The AMD includes a camera to acquire an image, and image-based authentication techniques are used to determine a user's identity. A user may move within in a physical space, and the space may contain various obstructions which may occlude images. The AMD may move within the space to obtain a vantage point from which an image of the face of the user is obtained which is suitable for image-based authentication. In some situations, the AMD may present an attention signal, such as playing a sound from a speaker or flashing a light, to encourage the user to look at the AMD, providing an image for use in image-based authentication.

  • Publication number: 20220234473
    Abstract: The present invention provides a method of thermal management for a power train. The temperature power source of the powertrain is continuously monitored. A heating request of is generated if the temperature of the power source falls below a threshold. In response to the heating request, the power controller of the powertrain generates a three-phase current to operate the asynchronous electric motor of the powertrain. The thermal energy therefore generated by the asynchronous electric motor is then provided to the power source for heating up the power source.

  • Patent number: 11157955
    Abstract: An online system tracks stores information identifying content provided by third party systems and accessed by online system users as well as interactions with advertisements performed by online system users. When the online system identifies an opportunity to present an advertisement to a viewing user, the online system identifies content from third party systems accessed by the viewing user and content from third party systems accessed by additional online system users who interacted with advertisements. A score is computed for various advertisements based at least in part on correlations between content from third party systems accessed by the viewing user and content from third party systems accessed by additional online system users who interacted with advertisements. The online system selects candidate advertisements to evaluate for presentation to the viewing user based on the scores.
