  • Publication number: 20240138698
    Abstract: A system for optimizing DBS parameters for a subject includes automatically performing actions via a processor. The actions include obtaining functional MRI data of a brain of the subject acquired utilizing an MRI system during DBS of the brain utilizing a first set of DBS parameters. The actions include generating functional MRI response maps from the functional MRI data. The actions include extracting, utilizing an unsupervised autoencoder-based neural network, features from the functional MRI response maps. The actions include determining, utilizing a deep learning-based DBS parameter classification model, whether the first set of DBS parameters are optimal DBS parameters for the subject based on the features. The actions include, when the first set of DBS parameters are not the optimal DBS parameters, predicting, utilizing a deep learning-based DBS parameter prediction model, a second set of DBS parameters that are the optimal DBS parameters for the subject based on the features.

  • Publication number: 20240070295
    Abstract: Disclosed embodiments pertain to protecting sensitive information. A browser extension associated with a web browser can detect a user entering information associated with the user into an electronic form. The browser extension can monitor the user entering sensitive information into the electronic form and detect that the user has entered sensitive information incorrectly. In response, the browser extension can provide a warning to the user that sensitive information has been incorrectly entered. Instructions can be displayed to a user on how incorrectly entered sensitive information is to be corrected. The incorrectly entered sensitive information is corrected based on a response from the user before the sensitive information propagates beyond the electronic form.

  • Publication number: 20220222006
    Abstract: Devices and/or methods may monitor data objects stored on a storage medium to detect presence of data objects that have not been accessed for a threshold period of time. Responsive to detecting that a data object has not been accessed for that threshold period of time, devices and methods may determine whether to perform an operation on the data object. The operation may include one or more of deleting the data object, purging the data object, converting the data object, compressing the data object, or transferring the data object to another storage device.

  • Patent number: 11245527
    Abstract: Secure distribution of data objects using a unique quantum-safe cryptographic key provided to a user requesting the data object that has been authenticated using a zero-knowledge authentication. A user may access the system by way of the zero-knowledge authentication to request access to a data object of a data library. The system may generate and associate a unique quantum-safe cryptographic key for the instance of the data library to be provided to the authenticated user. The data object is encrypted using the unique quantum-safe cryptographic key. The encrypted data object and the unique quantum-safe cryptographic key are provided to the authenticated user. Other instances of the data object may also be encrypted with other unique quantum-safe cryptographic keys. In turn, access to a unique quantum-safe cryptographic key may not be useful in decrypting other instances of the data object, and other data objects may not be decrypted using a given unique key for a given data object instance.

  • Publication number: 20210132826
    Abstract: Apparatus and method for local authentication of a collection of processing devices, such as but not limited to storage devices (e.g., SSDs, etc.). In some embodiments, each of the processing devices stores an internal token value as a unique ID value associated with the corresponding processing device. A host controller circuit performs a local authentication of the collection by accessing a distributed ledger as a data structure in a memory that lists the internal token values of the respective processing devices. The distributed ledger may take the form of a blockchain. The processing devices may each further store an external token value as the internal token value of a selected one of the other processing devices in the collection. A newly added device may be initially authenticated using a remote server. Once authenticated, the device is added to the collection and thereafter authenticated locally.

  • Patent number: 8297491
    Abstract: A packaging carton for wet food such as meat and fish is made of a triple ply lamination, the top and bottom plies being plastic sheet, the intermediate ply being of carton material such as paperboard but in variants the ply is made of fluted board, honeycomb matrix or side by side thin walled tubes. The intermediate ply is cruciform allowing the corners to be rectangular areas of plastic plies joined together. These form, diagonal fold flaps which are adhered to the cruciform blank to form a fold flat carton precursor. A lid is constructed in the same manner and overlies the carton to form a container which withstands tape wrapping.

  • Patent number: 7879436
    Abstract: A synthetic board is made from a plastic film ply 4, 6 adhered or welded to a parallel array of thin-walled plastic tubes 2. In some versions, the tubes are spaced from each other. In others the tubes are contiguous. This allows the board to curl up more or less depending on the tube packing about the tubes axes but to resist bowing between the ends of the tubes. The board is useful for packaging, display, cladding and insulation. In some versions, a second parallel array 7 lies at 90° to the first and the board is free to fold about the boundary between the two arrays. In this way, runs of cruciform carton blanks can be manufactured. The tubes can contain particulate or gel filling.
