Abstract: There is provided an apparatus and a method for the receipt and processing of data signals carried in a plurality of predefined frequency bands and allowing a frequency band required at an instant of time to be selected from the predefined frequency bands from which data is to be retrieved. Passing the data signals from the wanted band to a transmitter and/or receiver including first and second mixing means to process the data signals, typically using in-phase and quadrative data feeds to create a predefined representation of the wanted frequency band, to provide an output for receipt by at least one broadcast data receiver and at least the transmitter and/or receiver is provided as part of an integrated circuit rather than as separate connected components.

Abstract: A convection oven for use in a food delivery vehicle comprises an oven cavity with an air inlet and an air outlet, an air feed conduit for feeding an air feed into the oven cavity through the air inlet and a heating arrangement for heating the air feed before it is fed into the oven cavity, the heating arrangement comprising a heating device that is electrically powered and being arranged to maintain a temperature of at least 130° C. in the oven cavity. A food delivery vehicle may comprise such an oven and the oven may be heatable from an electric current provided by the engine of the vehicle.
