  • Patent number: 10628417
    Abstract: A database system determines execution plans for database queries by evaluating a number of partial solutions for each database query. The database system determines a partial solutions limit on the number of partial solutions to be evaluated for determining the execution plan of the query. The database system determines a plurality of partial solutions, each partial solution corresponding to a portion of the execution plan for processing the database query. The database system evaluates a number of candidate partial solutions for determining a partial solution. The number of candidate partial solutions evaluated is determined based on the partial solutions limit. The database system combines the plurality of partial solutions to obtain an execution plan for the database query. The database system executes the database query by executing the execution plan.

  • Publication number: 20200047293
    Abstract: A mobile welding system that does not rely exclusively on a track to define the path of the welder. One embodiment includes a mobile welder adapted to move along a work piece. The mobile welder includes a chassis, including a welding implement, and a travel assembly configured to support the chassis over a portion of the work piece. The mobile welder also includes a motor assembly configured to selectively cause the chassis to move relative to the work piece. The mobile welder further includes a chassis holder, having a magnet assembly, configured to provide a force holding the chassis a selected distance from the work piece.

  • Patent number: 10394807
    Abstract: A database system rewrites database queries based on rewrite constraints specification. The rewrite constraints specification provides directives to the database system to generate temporary tables for storing intermediate results of database queries and rewrite the corresponding database queries in terms of the temporary tables. The subqueries for matching the rewrite constraints specification may be specified in various ways. For example, the rewrite constraints specification may identify the subqueries by using one or more aliases. The rewrite constraints specification may specify a list of tables such that all database queries that join the database tables specified in the rewrite constraints specification are determined to match. The optimizer is able to optimize the rewritten database queries better by getting a better estimate for the statistics describing the temporary tables.

  • Patent number: 6284204
    Abstract: An ozone generating cell includes at least two substantially planar electrodes at a potential difference separated by a dielectric sheet, each producing a corona discharge to convert a proportion of any oxygen present to ozone. The electrodes, when considered in plan, are generally offset with regions of the electrodes overlapping or almost overlapping each other, and regions of both electrodes not overlapping each other. One or both planar electrode may feature extending planar portions of a substantially rectangular ‘U’ shape.

  • Patent number: 5440774
    Abstract: A disposable teeth cleaning kit includes a finger mounted toothbrush having a substantially cylindrical elastic sheath with a closed end and an open end. The sheath can be provided with internal longitudinal torque ridges to prevent rolling of the sheath during use. Brush means is disposed on the sheath adjacent its closed end and the sheath is adapted to be furled into a compact configuration wherein the furled portion forms a substantially annular rim bounding an area spanned by the closed end portion of the sheath and the brush means. The brush means is sized and configured to be surrounded and protected by the rim during storage and can be sealed in a protective sterile pod if desired. A sealed brush pod for attachment to an elastic sheath to form a finger mounted toothbrush comprises a base pad from which a bed of brush material projects. The bed of brush material is smaller than the pad to define a peripheral lip of the pad.

The brush means is sized and configured to be surrounded and protected by the rim during storage and can be sealed in a protective sterile pod if desired. In use, the toothbrush is unfurled onto a user's finger whereupon the finger is manipulated in the user's mouth to clean the teeth. When the teeth are cleaned, the brush is unfurled from the user's finger and discarded in an appropriate refuse receptacle.
