  • Publication number: 20260216426
    Abstract: Apparatuses and methods for an automated fluid delivery system having a flow control device including a pump and a control unit, a fluid administration set, a fluid sensor, and a plunger displacement sensor. The fluid administration set includes a syringe containing the fluid and tubing. The pump generates flow of the fluid from the syringe through the tubing. The fluid sensor detects the fluid in the tubing downstream of the syringe. The plunger displacement sensor is configured to detect linear displacement of the syringe plunger relative to the syringe barrel as fluid flows from the syringe through the tubing. The control unit determines an estimated inner cross-sectional dimension of the syringe barrel based on the linear displacement of the syringe plunger and detected fluid in the tubing downstream of the syringe, and operate the pump based at least in part on the estimated inner cross-sectional dimension of the syringe barrel.

  • Publication number: 20260185520
    Abstract: Operating, based on an objective volume of a fluid aliquot to be delivered during a subinterval, a pump motor of a flow-control apparatus for a first motor duration at a beginning of the subinterval to deliver less than the objective volume. A change in position of a first component of the container relative to position of a second component of the container over the first motor duration is sensed. A volume of fluid delivered over the first motor duration based on the sensed change in position is estimated. A second motor duration, ending no later than the end of the subinterval, to deliver a remainder of the objective volume of the aliquot is determined based on a difference between the objective volume of the aliquot and the estimated volume of the aliquot. The pump motor is operated for the second motor duration targeting delivery of the remainder of the aliquot.

  • Patent number: 12261933
    Abstract: Methods, systems, and devices for data processing are described. Some systems may support data processing permits and cryptographic techniques tying user consent to data handling. By tying user consent to data handling, the systems may comply with data regulations on a technical level and efficiently update to handle changing data regulations and/or regulations across different jurisdictions. For example, the system may maintain a set of data processing permits indicating user consent for the system to use a user's data for particular data processes. The system may encrypt the user's data using a cryptographic key (e.g., a cryptographic nonce) and may encrypt the nonce using permit keys for any permits applicable to that data. In this way, to access a user's data for a data process, the system may first verify that a relevant permit indicates that the user complies with the requested process prior to decrypting the user's data.

  • Patent number: 11983286
    Abstract: Methods, systems, and devices for data processing are described. Some database systems may implement data processing permits to manage data access. A database system may use encryption schemes to tie permits to data (e.g., cryptographically ensuring that the system follows data regulations). To support queries for a database implementing such encryption schemes, the database may implement a proxy. When the system receives a query, the database proxy may intercept and transform the query based on the encryption schema of the database. The database proxy may execute the transformed query at the database, receive encrypted query results in response, and decrypt the results for use by the querying application. Additionally, the system may access relevant data processing permits to support querying operations. For example, the system may use permits when transforming the query, executing the query in the database, preparing query results for the querying application, or any combination thereof.

  • Patent number: 11328082
    Abstract: Methods, systems, and devices for data processing are described. Some database systems may support differential privacy for encrypted data. For example, a database may store user data as ciphertext. A system may receive a statistical query for the user data and may identify a relevant differential privacy mechanism. The system may transform the query to operate on encrypted data while including a noisification function based on the mechanism. The system may execute the transformed query at the database, involving adding noise to the query result according to the noisification function without decrypting the data. For example, the system may leverage homomorphic encryption techniques to inject the noise while the data remains encrypted. The database may return the noisified, encrypted query results, which the system may decrypt for statistical analysis. By applying differential privacy on the encrypted data, the system may avoid exposing any private user information throughout the process.

  • Patent number: 10966859
    Abstract: A force distribution apparatus and method are presented. Various embodiments of the disclosed apparatus include a plurality of layers configured and oriented to be deployed on a subject in a manner that disperses forces and lowers peak pressures experienced by the subject when resting on a surface, which tends to minimize risks of deformation and local ischemia. An innovative combination of novel construction methods and material selections produce an apparatus that possesses an inherent three-dimensional shape despite being built from essentially flat components, while also retaining an ability to effectively distribute forces and reduce pressures.
