Abstract: Example embodiments of methods and apparatus for challenging an online user. In an example embodiment, a method includes receiving, at an online service provider, a request from a user to access one or more features of an online service running on a host server and also receiving an indication of a geography associated with the user. The example method further includes sending, to the user, information associated with the indicated geography in combination with information not associated with the indicated geography and a request that the user select the information associated with the indicated geography from the combined information or select the information not associated with the indicated geography from the combined information. The example method still further includes receiving, at the online service provider, a selection from the user and, in the event the selection correctly corresponds with the request, allowing the user access to the one or more features.

Abstract: A fluid pump kit is provided. The kit includes a magnetic driven member for coupling with and rotating a propeller, and a magnetic driver for magnetically coupling to and driving the magnetic driven member by a magnetic attraction force establishable between the magnetic driver and the magnetic driven member. A motor of the kit operates the magnetic driver. First and second casings are provided for housing the magnetic driver and the magnetic driven member, respectively. The first and second casings with housed magnetic driver and magnetic driven member, respectively, are detachably securable to opposite sides of a non-magnetic spacer solely by the magnetic attraction force establishable between the magnetic driver and the magnetic driven member sufficient to support the second casing and the housed magnetic driven member in a particular position without the use of mechanical aids.

Abstract: A foot spa tub includes a tub basin, a first magnetic drive member rotatably coupled to a drive motor, and a first casing supporting the magnetic drive member. The first casing is disposed against an exterior surface of a sidewall of the basin. A second magnetic drive member is rotatably coupled to a blade. The first and second magnetic drive members are magnetically coupled to each other so that the blade is drivingly coupled to the drive motor. A nozzle houses the second magnetic drive member and the blade. The nozzle is detachably securable to an interior surface of the sidewall by a magnetic attraction force between the first and second magnetic drive members. A method of circulating liquid in a foot tub spa is also provided.

Abstract: A system is provided for controlling an aquatic habitat. The system for includes a server, a bridge, and a habitat component. The server includes a database containing information associated with a habitat component. The server also includes a communication interface for transmitting operating data for the habitat component. The bridge has a first communication unit configured to communicate with the server communication interface and transmit the operating data received from the server to the habitat component. The habitat component has a second communication unit for receiving operating data from the bridge.

Abstract: Methods, computer program products and systems are described for obtaining at a first computer an online content item authored by an author for public online display. A credibility factor is determined for the author in association with the online content item. The credibility factor is based on information about the author to be true. In response to a query for online content, wherein the online content item is included in a set of search results, the ranking of the online content item in the set is determined in a second computer based at least in part on the credibility factor of the author. The first computer and the second computer can be the same or different computers.

Abstract: Provided is a fluid pump assembly. The pump has a pair of housings magnetically coupled to each other. The first housing contains a drive motor and a magnetic assembly. The second housing contains a magnetic assembly and a blade for imparting movement to a fluid. As the first magnetic assembly is rotated by the drive motor, the magnetic connection to the assembly in the second housing causes the second magnet to rotate, driving the blade.

Abstract: A fluid pump assembly is provided. The pump has a pair of units magnetically coupled to each other. The first unit contains a drive motor and a magnetic assembly. The second unit contains a magnetic assembly and a blade of a propeller/impeller for imparting movement to a fluid. As the first unit is activated by the drive motor, a magnetic flux is created which in turn rotates the magnetic assembly in the second unit, driving the blade.

Abstract: A fluid pump assembly is used in combination with a container having a wall. The pump assembly comprises a first casing disposed outside the container in contact with the wall, a first magnetic assembly mounted to the first casing and operatively associated with a drive motor, a second casing disposed inside the container in contact with the wall, and a second magnetic assembly mounted to the second casing and operatively associated with an propeller. The first magnetic assembly includes a rotatable magnetic drive member drivingly coupled to the drive motor. The magnetic drive member is magnetically coupled to the magnetic driven member through the wall for imparting a rotary driving force of the drive motor to the propeller. Furthermore, the second casing is detachably connected to the second side of the wall of the container solely by magnetic attraction force between the first and second magnetic assemblies.
