Abstract: The present invention describes the design and fabrication of Multi-Material-Blades used as active regenerative regenerators in active regenerative magneto-caloric or electro-caloric engines. The blades consist of a plurality of elements (2) that divide the blade body along its length. Each element (2) is made of a different magneto-caloric or electro-caloric material selected appropriately, and a plurality of dedicated channels (3) penetrates the blade body (1) and extends along the length of the blade. The dedicated channels (3) can be provided with fluid mixing structures, porous layers or hydrophobic coatings to reduce the HE loss in an active regenerative engine. The Multi-Material-Blades are obtainable by ink jet printing techniques to reduce costs. The Multi-Material-Blades can further have a curved shape to form an involute blade body (1). All measures can improve the performance of active regenerative magneto-caloric or electro-caloric engines, and lay the basis for commercial solutions.

Abstract: A method comprising: receiving, by wireless sites connected to a terrestrial network, a set of media that includes a plurality of individual media, wherein each of the wireless sites includes a satellite antenna and satellite receiver via which the set of media is received from a broadcast transmission from a satellite; storing the set of media, wherein each of the wireless sites stores the set of media in a local edge proxy server of the wireless site; receiving request(s) for media from mobile station(s); accessing the requested media from the set of media stored in the local edge proxy server; receiving requests for retransmission of said media from said mobile station(s); determining if a first of said retransmission requests is identical to a prior retransmission request; and if said first retransmission request is identical to said prior retransmission request, determining whether said prior retransmission request has been fulfilled.

Abstract: A modular evaporator which can be assembled from a number of standard modules is provided. Depending on the requirements, the modular evaporator can be assembled to meet a wide range of design cooling loads. Additionally, the modular evaporator is capable of generating and holding ice for thermal storage purposes, eliminating the need for external ice storage tanks. Furthermore, the heat transfer and thermal storage fluid for the evaporator can simply be water which considerably simplifies the system, lowers the cost, and increases the efficiency of the heat transfer loop.
