Abstract: A pole for a swimming pool comprises a tool for swimming pool maintenance located at one end of the pole and a device for preventing the pole from sliding into the swimming pool. The device comprises a face that surrounds the pole generally perpendicular to the pole and a baffle that extends from the outside edge of the face generally parallel to the pole. The device prevents the pole from sliding into the swimming pole by a user placing the baffle on a surface at the edge of the swimming pool.

Abstract: Intelligent content delivery enables content to be delivered to different devices in formats appropriate for those devices based on the capabilities of those devices. A user might access the same piece of content on two different devices, and can automatically receive a higher quality format on a device capable of playing that higher quality format. The user can purchase rights to content in any format, such that as new formats emerge or the user upgrades to devices with enhanced capabilities, the user can receive the improved formats automatically without having to repurchase the content. Further, the user can pause and resume content between devices even when those devices utilize different formats, and can access content on devices not otherwise associated with the user, receiving content in formats that are appropriate for those unknown devices even if the user has not previously accessed content in those formats.
