Abstract: An oven for processing food comprising a housing assembly defining a vent opening. The vent opening allows at least a portion of fluid within the food heating chamber to flow out of an exhaust port.

Abstract: One aspect of the invention provides a structure for holding cards having electronic and/or micromachined components. The structure provides a chassis comprising a plurality of bays for receiving cards such that the cards are oriented parallel to one another. Each bay comprises a fin front-plate fabricated from thermally-conductive material(s). Each fin front-plate is coupled to or integrally formed with a base in a manner which permits thermal conductivity therebetween. A backplane is located in a concave region in the base. For each bay holding a card, the backplane comprises an electrical connector for electronically coupling to a corresponding electrical connector on the card. When held in their respective bays, cards are thermally coupled to the fin front-plates. The base of the chassis preferably comprises an ingress port, an egress port and a network of conduits for conducting fluid which cools and/or redistributes the heat created by the cards and their components.
