Abstract: A system and computer implemented method for execution of aggregation expressions on a distributed non-relational database system is provided. According to one aspect, an aggregation operation may be provided that permits more complex operations using separate collections. For instance, it may be desirable to create a report from one collection using information grouped according to information stored in another collection. Such a capability may be provided within other conventional database systems, however, in a non-relational database system such as NoSQL, the system is not capable of performing server-side joins, such a capability may not be performed without denormalizing the attributes into each object that references it, or by performing application-level joins which is not efficient and leads to unnecessarily complex code within the application that interfaces with the NoSQL database system.

Abstract: Systems and methods for the preparation of recipe-based products may include a computer-based system for parsing recipe steps and instructions, such that each of a plurality of product preparation stations receives and displays on an associated human-machine interface only those instructions associated with that product preparation station.

Abstract: A database system comprising a database having a dynamic schema and at least one processor configured to: generate at least one column store index associated with the database, at least by: extracting keys from at least one document in the database, and sorting the keys; store the at least one column store index at least by storing the keys in the database; and access the at least one column store index based on at least one access request.

Abstract: Systems and methods are provided to enable control and placement of data repositories. In some embodiments, the system segments data into zones. A website, for example, may need to segment data according to location. In this example, a zone may be created for North America and another zone may be created for Europe. Data related to operations executed in North America, for example, can be placed in the North America zone and data related to transactions in Europe can be placed in the Europe zone. According to some embodiments, the system may use zones to accommodate a range of deployment scenarios.

Abstract: A headwear assembly is disclosed having an oximetry sensor and a circuit assembly configured to measure pulse and oxygen level for a user during exercise and/or physical activity. The oximetry sensor is positioned in a front section of the headwear assembly, proximate to the forehead when worn. Other sensors can also be included with the headwear assembly, such as temperature, blood pressure, and so on. The headwear assembly is configured to securely conform about a user's head when worn, such that the oximetry sensor is positioned and effectively immobilized on the forehead above the eyebrows. The headwear assembly can further provide integrated functionality with an external electronic device, such as a smart mobile phone. The headwear assembly can include a wireless charger for charging a rechargeable battery disposed on the headwear assembly.
