  • Publication number: 20250072438
    Abstract: An extreme vacuum cooling (EVC) method and apparatus is disclosed for rapid cooling, food treatment, and flavor infusion in commercial kitchens and food processing plants. Operating under ultra-low pressure with adaptive chamber pressure control, the EVC apparatus eliminates liquid splash and optimizes marinating and brining, achieving substantial time and energy savings. Available in single-unit and dual-module designs, this technology and apparatus enables swift, flexible, safer, less labor-intensive, and high-throughput food preparation operations.

  • Publication number: 20250045591
    Abstract: Methods, systems, and apparatuses are described herein for using machine learning to generate and use synthetic profiles. A computing device may train a machine learning model to generate synthetic user profiles. The computing device may then use the trained machine learning model to generate a plurality of synthetic user profiles based on real user profile information, provide those synthetic user profiles to a quote provider via an API, then average the quotes received from that provider to determine an expected quote for the real user. The computing device may also collect a plurality of quotes from a quote provider based on synthetic user profiles, then train a second machine learning model to estimate quotes by that provider. That trained second machine learning model may be used to estimate quotes for users, and may be re-trained based on real quotes provided by the quote provider at a later time.

  • Patent number: 12053006
    Abstract: A method and apparatus is disclosed relating to food preparation in commercial kitchens and food processing plants. The disclosed extreme vacuum cooling (EVC) technology and apparatus can work in ultra low pressure conditions with adaptive pressure control to avoid potential liquid splash inside the vacuum chamber caused by un-controlled low pressure conditions. Clean air is added into the vacuum chamber to allow the chamber pressure to track a setpoint trajectory that may have ramp up periods in order to avoid liquid splash events. The apparatus enables the user to cool various kinds of foods quickly, save energy, and meet food safety regulations.

  • Publication number: 20240188600
    Abstract: A method and apparatus is disclosed relating to controlled environment agriculture (CEA), food processing facilities, and commercial kitchens. The inventive smart and scalable extreme vacuum cooling (EVC) equipment is based on a scalable and modular design that allows one or multiple food chamber modules to connect to one utility module so that all food chambers can share the available vacuum cooling capacity dynamically. A scalable EVC system can be built, shipped and assembled with as few as one food chamber module and one utility module to a number of food chamber modules and a utility module. The food chambers are designed with different sizes in dimension and power requirements but with the same interface to the utility module. In this way, multiple food chamber modules can operate for food rapid cooling and flavor infusion supported by only one utility module. In a CEA farm, leafy greens are harvested daily and need to be chilled rapidly to comply with USDA food safety standards.

  • Patent number: 11935050
    Abstract: Systems and methods disclosed herein provide automatic expense categorization of transactions or expenditures based on a machine learning (ML) model trained using anonymized transactional data for expenditures that are stored in a public blockchain. The anonymized transactional data for the expenditure and the expense category, may be distributed throughout the blockchain network and recorded in the blockchain. In some implementations, an expenditure may be submitted to the blockchain network for expense categorization. The transactional data for the expenditure may be anonymized to remove confidential and personal identifying information (PII) before it is distributed throughout the blockchain network. Each participating node of the blockchain network may utilize the ML model to identify an expense category for the expenditure. The participating nodes may provide a consensus mechanism in order to arrive at a shared understanding of how to categorize the expenditure.

  • Publication number: 20240054488
    Abstract: Disclosed embodiments may include a system for generating aggregate records. The system may retrieve data corresponding to a first user. The system may receive, from the first user, first sharing preference(s) associated with a second user. The system may extract first data subset(s) from the data based on the first sharing preference(s). The system may generate block(s) of a blockchain ledger. The system may append the first data subset(s) to at least a first block of the block(s) of the blockchain ledger. The system may provide the second user with access to the first data subset(s) on the at least first block.

  • Patent number: 11900386
    Abstract: This application relates to apparatus and methods for identifying fraudulent payment transfers. In some examples, a computing device determines payment transfer initiation features, and payment transfer reception features, based on previous payment transfer data. The computing device may train a machine learning fraud detection model with the payment transfer initiation features, and may train a machine learning fraud detection model with the payment transfer reception features. Once trained, the computing device may employ the machine learning fraud detection models to identify fraudulent payment transfers. For example, the computing device may determine whether a payment transfer is fraudulent when the payment transfer is initiated. Assuming the payment transfer is allowed, the computing device may determine whether the payment transfer is fraudulent when the payment is being received.

  • Patent number: 10837012
    Abstract: Methods are provided for assembly of a target polynucleotide sequence comprising at least a first double stranded polynucleotide (DSP) and at least second DSP, and optionally further DSPs. The method comprises an assembly reaction comprising steps including providing a first single stranded polynucleotide (SSP) comprising the polynucleotide sequence of one strand of the first DSP, and a second SSP comprising the polynucleotide sequence of one strand of the second DSP and converting the SSPs to double stranded form via a primer and polymerase-mediated extension reaction. The DSPs comprise polynucleotide sequences that are complementary to other polynucleotide sequences within the assembly reaction such that the ordering and directionality of each of the first and second, and further DSPs is determined by unique overhang pairing. Nucleic acid libraries and methods of making such libraries are also provided.

  • Publication number: 20200279255
    Abstract: A system and method for using device characteristics to authenticate a transaction is disclosed. A first device can be used to request a transaction, and a second device can be used to approve the transaction. A push notification or authentication code is transmitted to a second device, and approval of the transaction is completed based in part on the hardware characteristics of the second device. A security database stores the hardware characteristics of the second device and links the characteristics to authentication profiles such that the second device can be used as a physical authentication device in multi-factor authentication.
