A method including receiving a model of a composite structure having an inconsistency. The model includes a pre-calculated heating model that specifies areas of the inconsistency for which corresponding different amounts of heating are applied to an uncured composite material that is applied to the inconsistency. A design for heating elements of varying density across the areas is generated from the model. The design is configured to cause the heating elements in a first sub-area of a heat blanket system to generate a first amount of heat in a third area in the areas, and to cause the heating elements in a second sub-area of the heat blanket system to generate a second, different amount of heat in a fourth area of the areas. The heating elements are printed according to the design on a blanket to manufacture the heat blanket system.

A heater to heat a container within which food is to be cooked. The heater includes a flexible elongated base that is to at least partly surround the container periphery, so that the heater can be urged towards the periphery. A heating element is attached to the base of the container to enable the heating element to be in thermal contact with the periphery. An elongated power conduit is connected to the heating element to provide for the connection of the heating element to a source of electric power so that upon electric power being delivered to the heating element, the heating element can heat the container.

Embodiments of the invention are directed to an apparatus that includes a moveable gripper element that includes a flexible inner sleeve. A mechanical energy source mechanism is communicatively coupled to the moveable gripper element, and the flexible sleeve defines an opening. The mechanical energy source mechanism transfers to the moveable gripper element a gripping force configured to move the moveable outer sleeve, reduce a size of the adjustable opening, and bring the flexible inner sleeve into an initial level of thermal contact with a container positioned within the adjustable opening. The mechanical energy source mechanism is configured to, subsequent to establishing the initial level of thermal contact, make adjustments to the gripping force, wherein the adjustment to gripping force increase thermal contact points at an interface between the flexible inner sleeve and the container; and displace air from the interface between the flexible inner sleeve and the container.
