  • Determination of data partition
    Patent number: 10747781
    Abstract: Partitioning a set of data using a binary format to more evenly distribute data values across a set of data partitions. By using a system of matching binary indices in a “back to front” manner, data values stored in or associated with data partitions are more evenly balanced.
    Type: Grant

  • Swivel base assembly for use in conjunction with an electrically powered chair
    Patent number: 10376061
    Abstract: A swivel base assembly, for use in conjunction with an electrically powered chair, is disclosed. The swivel base assembly provides the necessary electrical power to the electrically powered chair without the electrical power cord becoming entangled around the upstanding column, or similar support structure, upon which the body portion of the electrically powered chair is mounted upon the swivel base assembly if the electrically powered chair is rotated multiple times through means of an angular displacement or movement of 360° or more, as a result of the disposition of a rotary electrical connected interposed between the swivel base assembly and the electrically powered chair.

  • Index structure for a relational database table
    Patent number: 9600507
    Abstract: Embodiments are directed to building an index structure for a relational database (RDB) table and for querying the RDB table. An aspect includes obtaining JSON documents from a RDB table, identifying JSON objects in the JSON documents and assigning identifiers for them, and building an index structure according to values in the JSON objects such that the index structure includes at least one node that records values in a JSON object and includes the identifier of the specific JSON object. Querying the RDB table includes receiving a query request including an indicator which indicates that the query is to be performed on JSON objects, and searching the index structure based on query conditions in the query request so as to determine a target JSON object that meets the query conditions.
