  • Publication number: 20250226990
    Abstract: Methods and systems are presented for using blockchain technologies to establish and manage personal profiles for users. A credential system registers a user by generating a token associated with a blockchain for the user, and storing authentication data associated with the user in the blockchain. The authentication data may include encoded data that represents an identification document and biometric data. After registering the user with the credential system, a verifier device can authenticate the user via the credential system using the authentication data stored on the user device. Additional information, such as interaction data associated with the user's interaction with various computer system can be added to the blockchain using the token generated for the user. The interaction data of the user with various computer systems, collectively, forms a universal personal profile of the user, and can be used by the various computer systems to manage the user.

  • Publication number: 20250202523
    Abstract: According to one embodiment, a compact broadband radio frequency (RF) frontend circuit includes a number of single-channel transceivers, a number of analog to digital converters (ADCs), where each of the ADCs is coupled to one of the single-channel transceivers, a number of digital to analog converters (DACs), where each of the DACs is coupled to one of the single-channel transceivers, and a digital signal processing (DSP) unit coupled to the ADCs and the DACs. The DSP unit is configured to generate a first set of digital data streams simultaneously and each of the first set of digital data streams is converted by a respective one of the DACs into an analog data stream to be transmitted to a remote device by a respective one of the single-channel transceiver.

  • Publication number: 20250182096
    Abstract: Methods and systems are presented for providing a token exchange framework that enables exchanges of reward tokens corresponding to different reward systems and/or different merchants. The token exchange framework includes a blockchain for storing transaction data associated with transactions of reward tokens. During the onboarding process, reward systems associated with different merchants may be connected to the blockchain of the token exchange framework via one or more bridges. Reward tokens may be issued to represent reward data corresponding to the different reward systems, and can be freely exchanged within the token exchange framework via the blockchain. When a transaction for redeeming a reward is received, reward tokens in the blockchain can be converted into reward data corresponding to the merchant's reward system and process the transaction with the merchant using the converted reward data.

  • Publication number: 20250127730
    Abstract: The present invention relates to using monoterpene or sesquiterpene to permeabilize the blood brain barrier. The present invention relates to a method of treating a central nervous system (CNS) cancer wherein perillyl alcohol (POH) is administered to a mammal before or concurrently with a therapeutic agent that is a chimeric antigen receptor T-cell (CAR-T cell). The POH and CAR-T cells can be administered by intraarterial injection. The CNS cancer can be a malignant glioma, pilocytic astrocytomas (grade I), meningiomas, metastatic brain tumors, or pituitary adenomas.

  • Patent number: 12236419
    Abstract: Methods and systems are presented for providing instant authentication of a product and enhanced user experience with the product via blockchain technologies. A product verification system uses blockchain technologies to track the supply chain process of each instance (e.g., each copy) of a product. Upon receiving a request for authenticating an item, a code provided with the item is scanned. A token corresponding to an instance of a product is determined based on the code. The product verification system traverses a blockchain to access data associated with the token. The item is authenticated based on the data. Additional content provided by the supply chain and/or the manufacturer of the instance of the product may be presented on a user device in response to authenticating the item.

  • Publication number: 20250028745
    Abstract: Methods and systems are presented for facilitating a context-aware dialogue with a user. A chat system identifies a particular domain associated with a query received from the user. Contents are retrieved from one or more data sources that are associated with the particular domain. A semantic-based algorithm and a term-based algorithm are used on tandem to rank the contents, where a selective subset of contents is identified based on the ranking. An enriched prompt is generated for an artificial intelligence (AI) model by integrating the subset of contents into the query. The enriched prompt is then provided to the AI model. The AI model is configured to generate a response to the query based on the enriched prompt.

  • Publication number: 20240239730
    Abstract: The present invention provides a process for purifying a monoterpene or sesquiterpene having a purity greater than about 98.5% (w/w). The process comprises the steps of derivatizing the monoterpene (or sesquiterpene) to produce a monoterpene (or sesquiterpene) derivative, separating the monoterpene (or sesquiterpene) derivative, and releasing the monoterpene (or sesquiterpene) from the derivative. Also encompassed by the scope of the present invention is a pharmaceutical composition comprising a monoterpene (or sesquiterpene) having a purity greater than about 98.5% (w/w). The purified monoterpene can be used to treat a disease such as cancer. The present monoterpene (or sesquiterpene) may be administered alone, or may be co-administered with radiation or other therapeutic agents, such as chemotherapeutic agents.
