Abstract: A system and a method of sampling from a probability distribution approximating a Boltzmann distribution of an n-spin Ising model includes receiving, by a classical computer, coupling coefficients for spin-spin interactions, field coefficients local to each spin, and a temperature for the n-spin Ising model; selecting a first n-spin configuration; preparing a first n-qubit state on a quantum computer associated with the first n-spin configuration; applying a unitary operator to the first n-qubit state resulting in a second n-qubit state; measuring the second n-qubit state to identify a corresponding second n-spin configuration; calculating, on the classical computer, an acceptance probability to determine whether to replace the first n-spin configuration with the second n-spin configuration or to keep the first n-spin configuration to obtain an output n-spin configuration; and repeating the preparing, applying, measuring and calculating until the output n-spin configuration is sufficiently close to the Boltzm

Abstract: An electrical cabinet for an uninterruptibe power supply (UPS) system includes universal slots that can receive power modules, battery packs, or chargers. The back plane of the slot has connector terminals for battery packs and power modules. The cabinet can be easily reconfigured as desired by changing the number of power modules chargers or battery packs installed. Circuitry is provided that indicates the capacity and operational readiness of the cabinet. This circuitry monitors the battery packs in each slot, and isolates any detected fault to a particular pack.

Abstract: Systems and methods that retrieve at least one data element from a database include a database and a plurality of predefined query procedures, each predefined query procedure referencing an inquiry path, entering a query having a query procedure and at least one parameter, locating the query procedure and the referenced inquiry path, and using the referenced inquiry path with the parameter to retrieve at least one data element from the database, that is the result of the query. Generally, the system will be used to retrieve data for entity-relation databases (ERDBs) using Structured Query Language (SQL) queries, but that is not required.

Abstract: An electrical cabinet or chassis for an uninterruptible power system (UPS system) includes universal bays or slots that can receive either power modules or battery backs. The back plane of the slot has separate connector terminals for battery packs and power modules. The slots may also receive battery chargers if so desired. All of the slots of a chassis can be utilized to full capacity before another cabinet needs to be employed. The cabinet is also readily adaptable and can be easily reconfigured as desired without particular concern as to the number of power modules or battery packs that are being used. Sensors are provided which indicate the capacity of the cabinet that has been used (e.g. the number of slots still open and not used by a power module or a battery pack).
