A plurality of jet orifices provide an exit for pressurised liquid to exit a plenum chamber and impinge on a thermal surface whereby they effect a cooling of the thermal surface, the heated liquid being transferred through an exit channel to dissipate heat away from the thermal surface.

Abstract: Embodiments relate to a system for booking a resource, the system being configured to receive resource data, resource record data, and offer data. The system associates an offer with a resource and a resource record to generate a booking offering, which is transmitted to a user. The system presents the resource, the resource record, the offer, and the booking offering to the user at a user-device. The system receives a selection, by the user on the user-device, of the booking offering. The system then facilitates a transfer of electronic funds from a user to a commercial partner upon selection of the booking offering, and facilitates a transfer of an electronic certificate representative of the offer from the commercial partner to the user.
