  • Publication number: 20230297074
    Abstract: Approaches provide for performance of a complex (e.g., compound) task that may involve multiple discrete tasks not obvious from an instruction to perform the complex task. A set of conditions for an environment can be determined using captured image data, and the instruction analyzed to determine a set of final conditions to exist in the environment after performance of the instruction. These initial and end conditions are used to determine a sequence of discrete tasks to be performed to cause a robot or automated device to perform the instruction. This can involve use of a symbolic or visual planner in at least some embodiments, as well as a search of possible sequences of actions available for the robot or automated device. A robot can be caused to perform the sequence of discrete tasks, and feedback provided such that the sequence of tasks can be modified as appropriate.

  • Publication number: 20230259540
    Abstract: In various examples, a conversational artificial intelligence (AI) platform uses structured data and unstructured data to generate responses to queries from users. In an example, if data for a response to a query is not stored in a structured data structured, the conversational AI platform searches for the data in an unstructured data structure.

  • Publication number: 20230120989
    Abstract: In various examples, systems and methods of the present disclosure combine open and closed dialog systems into an intelligent dialog management system. A text query may be processed by a natural language understanding model trained to associate the text query with a domain tag, intent classification, and/or input slots. Using the domain tag, the natural language understanding model may identify information in the text query corresponding to input slots needed for answering the text query. The text query and related information may then be passed to a dialog manager to direct the text query to the proper domain dialog system. Responses retrieved from the domain dialog system may be provided to the user via text output and/or via a text to speech component of the dialog management system.

  • Publication number: 20210358188
    Abstract: In various examples, a virtually animated and interactive agent may be rendered for visual and audible communication with one or more users with an application. For example, a conversational artificial intelligence (AI) assistant may be rendered and displayed for visual communication in addition to audible communication with end-users. As such, the AI assistant may leverage the visual domain—in addition to the audible domain—to more clearly communicate with users, including interacting with a virtual environment in which the AI assistant is rendered. Similarly, the AI assistant may leverage audio, video, and/or text inputs from a user to determine a request, mood, gesture, and/or posture of a user for more accurately responding to and interacting with the user.

  • Publication number: 20210229601
    Abstract: Systems and methods for a self-adjusting vehicle mirror. The mirror automatically locates the face of the driver or another passenger, and orients the mirror to provide the driver/passenger face with a desired view from the mirror. The mirror may continue to reorient itself as the driver or passenger shifts position, to continuously provide a desired field of view even as he or she changes position over time. In certain embodiments, the mirror system of the disclosure can be a self-contained system, with the mirror, mirror actuator, camera, and computing device all contained within the mirror housing as a single integrated unit.

  • Patent number: 10459873
    Abstract: The invention provides a method for adaptively adjusting a framerate of a graphic processing unit (GPU). For example, when the GPU workload is high and the temperature of the GPU is close to high temperature, the framerate can be decreased to reduce the workload; when the GPU workload is low, the framerate can be permitted to increase to raise the workload. By the present invention, the GPU is permitted to operate at maximum temperature. The method comprises the steps of: (a) receiving an execution parameter associated with at least one GPU; (b) comparing if the execution parameter is greater than a first reference value; and (c) in the event the execution parameter is greater than the first reference value, increasing a sleep time and power-gating the at least one GPU based on the sleep time to adjust the framerate.

  • Patent number: 9870375
    Abstract: Various embodiments relating to reducing memory bandwidth consumed by a continuous scan display screen are provided. In one embodiment, scoring criteria are applied to a reference image of a first image format having a first bit depth to generate an image conversion score. The scoring criteria are based on a histogram of one or more characteristics of the reference image. If the image conversion score is greater than a threshold value, then the reference image is converted to a modified image of a second image format having a second bit depth less than the first bit depth, and the modified image is scanned onto the continuous scan display screen. If the image conversion score is less than the threshold value, then the reference image is scanned onto the continuous scan display screen.

  • Publication number: 20140229754
    Abstract: Embodiments disclosed herein generally relate to the collection and correlation of power consumption data for mobile devices. Power consumption data for a mobile device is collected and correlated with system activity by monitoring what processes are being run on the CPU and measuring the power being consumed within the mobile device. The power being consumed within the mobile device is measured via a plurality of power monitors, such as sensors, disposed within the mobile device and buffered using an auxiliary microcontroller that resides separately from the CPU. Further, in some embodiments, temperature data also is measured via a temperature sensor.
