  • Balanced flow dialysis machine
    Patent number: 11931492
    Abstract: A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber.

  • Device-based PIN authentication process to protect encrypted data
    Patent number: 10469469
    Abstract: Techniques are disclosed for providing a device-based PIN authentication process used to protect encrypted data stored on a computing system, such as a tablet or mobile device. A client component and a server component each store distinct cryptographic keys needed to access encrypted data on the client. The mobile device stores a vault encryption key used to decrypt encrypted sensitive data stored on the mobile device. The vault key is encrypted using a first encryption key and stored on the mobile device. The first encryption key is itself encrypted using a second encryption key. The second encryption key is derived from the PIN value.

  • Online predictive memory
    Patent number: 6078918
    Abstract: One embodiment of the present invention provides a system for making predictions about data records from an incoming stream of data records. This system operates by discovering predictive relationships in an online manner between fields in records in the incoming stream of data records as the incoming stream of data records is received. These predictive relationships can used to predict values in fields based on other field values in the same record. This facilitates cleansing of data by allowing transaction values to be validated based upon predictions made from other field values in the same transaction record. It also allows missing field values to be predicted based upon the other field values. A variation of this embodiment provides for filtering transaction records based upon discovered predictive relationships and routing the transaction records to other servers in real-time.
