Abstract: A materialization configuration request is received via a programmatic interface from a client of a journal-based multi-data-store database. The request indicates a partitioning rule to be used to select, for respective writes indicated in committed transaction entries of a journal, the materialization node at which the writes are to be stored. A control plane component of the database verifies that a set of materialization nodes corresponding to the partitioning rule has been established, and initiates the propagation of writes from the journal to the materialization nodes by respective write appliers.

Abstract: Fluid control systems, including mass flow control systems, mass flow ratio control systems, and mass flow and ratio control systems, as well as corresponding methods for fluid control are provided. These systems allow one shared pressure sensor to be used for multiple flow channels, and a controller which can accurately determine mass flow on the basis of fluid pressure detected by this shared pressure sensor.

Abstract: A mass flow verifier (MFV) that is space-efficient and can verify flow rates for unknown fluids over a wide range of flow rates includes a chamber configured to receive a fluid, a critical flow nozzle connected to the chamber, and first and second pressure sensors that, respectively, detect fluid pressure in the chamber and upstream of the critical flow nozzle. A controller of the MFV is configured to verify flow rate of the fluid by, (i) at a first flow range, measuring a first flow rate based on a rate of rise in pressure of the fluid as detected by the first pressure sensor and determining a gas property function of the fluid based on pressures as detected by the first second pressure sensors, and (ii) at a second flow range, measuring a second flow rate based on pressure detected by the second pressure sensor and the determined gas property function.

Abstract: An apparatus and method for measuring the air leakage rate of a structure, such as a building, for the purpose of assessing the need to add caulking, weatherstripping or the like to the building to minimize energy loss. The equipment includes a panel which may conveniently fit into a doorway or window frame of the building and seal the same against air leakage except for an air pathway passing through the panel. The pathway has a fan or the like for causing air to flow through the pathway, preferably from the inside to the outside to create a partial vacuum inside the building. Pressure sensors are provided to measure the partial vacuum and the air pressure inside the air pathway. From these measurements and a knowledge of the total internal volume of the building structure, the air leakage rate of the structure can be determined and expressed, for example, as a number of total volume changes per hour. The apparatus is portable and can be used for almost any building without structural modification.

Abstract: An electronic control logic system for processing the results of a spectrophotometer analysis of a serum chemistry comprised of a serum and one or more chemical reagents. The spectrophotometer output representing air as a light path and another output representing the test chemistry as a light path are integrated and the air path integrated value allowed to exponentially decay until its value is equal to that of the integrated test chemistry path value. The decay time is converted into a train of digital pulses representative of the optical density of the test chemistry. These pulses are counted and their total stored for comparison with the corresponding optical density of a standard solution. The concentration of the element for which the particular test was designed to detect is known for the standard solution, so the percentage concentration of that element in the test chemistry may be thereby ascertained.
