  • Publication number: 20240386328
    Abstract: A method, referred to herein as upside down reinforcement learning (UDRL), includes: initializing a set of parameters for a computer-based learning model; providing a command input into the computer-based learning model as part of a trial, wherein the command input calls for producing a specified reward within a specified amount of time in an environment external to the computer-based learning model; producing an output with the computer-based learning model based on the command input; and utilizing the output to cause an action in the environment external to the computer-based learning model. Typically, during training, the command inputs (e.g., “get so much desired reward within so much time,” or more complex command inputs) are retrospectively adjusted to match what was really observed.

  • Publication number: 20240347040
    Abstract: Systems and methods for providing notifications without breaking media immersion. A notification delivery application receives notification data while a media device provides a media asset. In response to receiving the notification data while the media device provides the media asset, the notification delivery application generates a voice model based on a voice detected in the media asset. The notification delivery application converts the notification data to synthesized speech using the voice model and generates, by the media device, the synthesized speech for output at an appropriate point in the media asset based on contextual features of the media asset.

  • Publication number: 20240329153
    Abstract: Various implementations described herein are related to a device with fabrication test circuitry having transistors arranged in a parallel branch configuration between a supply voltage and a single pad. In some applications, each transistor in an off-current branch may be separately deactivated so as to test leakage current applied to the pad by way of the off-current branch, and also, each transistor in an on-current branch may be deactivated so as to further test the leakage current applied to the pad by way of the off-current branch.

  • Publication number: 20240281403
    Abstract: Embodiments of the present disclosure may relate to apparatus, process, or techniques in a I3C protocol environment that include identifying a pending read notification message by a slave device to be sent to a master device to indicate that the data is available to be read by the master device from a buffer associated with the slave device. The pending read notification may be subsequently transmitted to the master device. Subsequently, until the data in the buffer has been read by the master device, the slave device may wait an identified amount of time that is less than a value of a timeout of the master device, and retransmit the pending read notification message to the master device. Other embodiments may be described and/or claimed.

  • Publication number: 20240111714
    Abstract: Direct Image Lookup (DIL) metadata is used to perform differential operation for snapshots and linked targets. Each snapshot contains metadata to store “images” to perform direct lookup of user data for any part of any snapshot in the system. Metadata pages of DIL image data represent sets of tracks of data. Metadata pages of subsequent snapshots for the same sets of tracks are compared, and where there are no changes to a given metadata page for a given set of tracks between subsequent snapshot copies, the differential process is not run on the tracks associated with the metadata page. If a given metadata page associated with a set of tracks has changed between subsequent snapshots, the differential process is used to identify which tracks in the subsequent snapshot contain different data than the corresponding tracks of the previous snapshot. Similar differential processing also is implemented for relinked target devices.

  • Patent number: 11927537
    Abstract: The present invention relates to a cost effective and single step process for rapid manufacturing of paper-based SERS substrates (100), wherein chitosan is used for direct in situ reduction of the metallic precursor solutions for production of metallic nanoparticles on the substrates. The crucial step in the process involves the incubation of the paper-based substrates under humidifying conditions at an elevated temperature for a predetermined duration. The metal nanoparticles thus produced are homogenously deposited over the paper-based substrate making the paper-based substrate suitable for SERS analysis. The paper-based substrate thus developed is cost-effective, flexible, easy to load and is demonstrated to have exceptional sensitivity with detection limits of up to 1 pM.

  • Patent number: 11880114
    Abstract: Techniques for using ferroelectric liquid crystals Dammann grating (FLCDG) for light detection and ranging devices are disclosed. In LiDAR devices, accuracy, response time, and cost performance can be limited by some factors, such as laser pulse width, time resolution of a time-to-digital conversion chip, detector bandwidth, shot noise, and time error generated by electronic circuits. A FLCDG-based architecture can improve a LiDAR device, and provide for one-shot capturing due to the high switching speed at very low driving voltage provided by ferroelectric liquid crystals and the equal diffracting ability of Dammann grating.

  • Publication number: 20240018050
    Abstract: A novel eco-friendly method has been developed for the fabrication of high dense (3.3-5.2 g/cc) red mud based material blocks for shielding high energy X- and ?-rays. The red mud based material blocks with various densities were fabricated by hot compacting partially melted red mud, red mud:Bi2O3, red mud:Ba(OH)2 and red mud:Bi2O3:Ba(OH)2 samples at 1150° C., 1000° C., 1050° C. and 1000° C., respectively. This material can be used to build radiation shielding structures in medical diagnosis, radiotherapy, industrial radiography, particle accelerators, food sterilization plants, nuclear power plants, and radioactive material storage rooms, without further structural support unlike lead (concrete walls). It is economically viable and will suppress the accumulation of hazardous red mud and associated environmental pollutions.
