  • Publication number: 20200151726
    Abstract: Embodiments of the invention are directed to systems and methods for utilizing a cache to store historical transaction data. A predictive model may be trained to identify particular identifiers associated with historical data that is likely to be utilized on a particular date and/or within a particular time period. The historical data corresponding to these identifiers may be stored in a cache of the processing computer. Subsequently, an authorization request message may be received that includes an identifier. The processing computer may utilize the identifier to retrieve historical transaction data from the cache. The retrieved data may be utilized to perform any suitable operation. By predicting the data that will be needed to perform these operations, and preemptively store such data in a cache, the latency associated with subsequent processing may be reduced and the performance of the system as a whole improved.

  • Publication number: 20200038071
    Abstract: An interspinous process device is configured for placement between adjacent spinous processes on a subject's spine. The device includes a housing configured for mounting to a first spinal process, the housing having a lead screw fixedly secured at one end thereof. A magnetic assembly is at least partially disposed within the housing and configured for mounting to a second spinal process. The magnetic assembly includes a hollow magnet configured for rotation within the magnetic assembly, the hollow magnet comprising a threaded insert configured to engage with the lead screw. An externally applied magnetic field rotates the hollow magnet in a first direction or a second, opposite direction. Rotation of the hollow magnet in the first direction causes telescopic movement of the magnetic assembly out of the housing (i.e., elongation) and rotation in the second direction causes telescopic movement of the magnetic assembly into the housing (i.e., shortening).

  • Patent number: 10545476
    Abstract: A method of self-balancing a plurality of mechanical components within a temperature control unit of an HVAC system. Each mechanical component is adjustable by the controller to vary airflow within the temperature control unit. For each mechanical components, a property is measured. An estimated condition of the mechanical component is calculated based on the measured property and known qualities of the temperature control unit. A desired condition for the mechanical component is determined based on a desired air condition within the HVAC system or building envelope. The estimated condition of the mechanical component is compared to the desired condition of the component. The condition of the mechanical component is changed using a controller to more closely align the estimated condition to the desired condition to achieve the desired indoor air condition. Steps are repeated until the difference between the estimated condition and desired condition is within a threshold value.
