Abstract: A surfboard with a surfboard body (1) extending along a longitudinal direction (L) and having an upper surface and a bottom surface. An electrical battery pack (2) is removably positioned in an upper compartment accessible from the upper surface. An electrically driven water-jet configured to propel the surfboard is provided with electrical power from the electrical battery pack. The electrically driven water-jet is provided in a propulsion module (3) that is removably positioned in a lower compartment accessible from the lower surface. The upper compartment and the lower compartment partly overlaps each other as seen along the longitudinal direction (L).

Abstract: A publisher web server may receive from an end user device a web page request. A plug-in installed at the publisher web server may transmit information about the request to an advertisement blocking circumvention platform. The platform may respond with information including an invalid URL resource address, and the publisher web server may transmit a data package, including the information about the invalid URL, to the end user device. The publisher web server may then receive from the end user device a resource request including the invalid URL, and information about the invalid URL may be forwarded to the platform. Responsive to receiving the information about the invalid URL, the platform may transmit a message (including advertising content) and the publisher web server may transmit to the end user device a response to the resource request such that the advertising content will be delivered via the end user device.
