A plastic internally hollow body has a cavity for containing liquids, solids or gases, and includes a main body shaped and having an inner surface at least partially defining the cavity. The inner surface terminates in a shaped edge that delimits a coupling aperture to the cavity. The internally hollow body includes a closure body, having an outer sealing surface suitable at least partially engaging the inner surface of the main body. The closure body at least partially closes the cavity in correspondence of the coupling aperture. The main body is joined to the closure body at least partially along the shaped edge by a joining element over-moulded to the main body and the closure body and covering the over-moulding seat resulting between the main body and the closure body. A method for making the internally hollow body over-moulds the joining element by injection moulding with an over-moulding mould.

A device (10) for detecting a signal of interest in order to locate an underwater source of the signal. The device includes a receiver (13) configured to detect the signal of interest, an actuator (14) configured to allow at least a portion of the detection device (10) to move towards a zone indicating a result of detection of the signal of interest in response to the receiver being operated, and an emitter (15) configured to indicate the result of detection of the signal of interest.

The generation of electronic notifications relating to ocean waves. Embodiments include frameworks and methodologies configured to enable real-time location-specific determination of recreationally relevant wave characteristic data, including (bot not limited to) generation and delivery of location-specific ocean wave notifications. Embodiments include, by way of example, technology for providing real-time location-specific determination of recreationally relevant wave characteristic data, portable and/or wearable devices configured to deliver notifications in respect of approaching waves, wave monitoring devices and frameworks configured to enable generation of alert notifications for surfers, rock fishers and other recreational users, and generation and delivery of location-specific ocean wave data, including visual data for event broadcasts.
