A heated food container, comprising an enclosure with an enclosure opening and a bottom opposite the opening, the enclosure defining an enclosure inner space accessible through the enclosure opening; at least one portable heating element positioned on the bottom of the enclosure capable of heating the enclosure inner space; and a grill positioned on the bottom of the enclosure directly above the at least one portable heating element.

Self-heating containers comprise a reaction chamber and a heating chamber. The heating chamber is sized to contain a substance to be heated. The reaction chamber contains reactants which, when contacted, exothermically react. The reaction chamber is divided into a first compartment and a second compartment with a barrier therebetween. The barrier comprises a first barrier portion and a second barrier portion. The first barrier portion is attached to a reaction chamber wall and has an opening sized to allow reactants to flow through from one compartment to the other. The second barrier portion is attached to the first barrier portion to close the opening. The barrier can be opened by moving an actuator into engagement with the second barrier portion to dislodge the second barrier portion from the first barrier portion and thereby open the barrier. In certain embodiments, the heating chamber can be a can with prepackaged comestible substance therein. Examples of components configured to facilitate such a can are disclosed.

Coffee or other drink, for example a caffeine containing drink, is delivered to individuals that would like the drink, or who have a predetermined cognitive state, using an unmanned aerial vehicle (UAV)/drone. The drink is connected to the UAV, and the UAV flies to an area including people, and uses sensors to scan the people for an individual who has gestured that they would like the drink, or for whom an electronic analysis of sensor data indicates to be in a predetermined cognitive state. The UAV then flies to the individual to deliver the drink. The analysis can include profile data of people, including electronic calendar data, which can be used to determine a potentially predetermined cognitive state.

Ammonium carbamate-based methods and systems for management of thermal loads, particularly low-quality, high-flux thermal loads. The increase in temperature in heat sensitive devices is mitigated by the endothermic decomposition of ammonium carbamate into carbon dioxide and ammonia gases. This process has an energy density an order of magnitude greater than conventional thermal management materials and is particularly useful for temperatures between 20 C. and 100 C. Systems incorporating ammonium carbamate may be controlled by regulating the fluid flow, overhead pressure, temperature, or combinations thereof.

A flexible pouch for heating articles includes a pair of panels forming a compartment and a pair of heating units which are disposed on either side of the compartment to heat the articles within the compartment. Seal portions are formed adjacent side edges for forming a holding area to be grasped by the hand of the user.

Instant self-heating containers include a combinable reactant and activator used to generate an exothermic reaction for heating contents of the container. One instant self-heating container includes a target container, a pierceable activator container and a reaction chamber. Piercing the activator container causes activator to combine with the reactant and cause an exothermic reaction that heats the target container. The container may be used as depilatory wax dispenser. Another instant self-heating container includes an outer housing containing a contents pouch and a reactant, and capped by a lid having an activator chamber. Rupturing the activator chamber allows activator to combine with the reactant in an exothermic reaction to heat the contents pouch. Another instant self-heating container includes a flexible outer tube containing contents to be heated, a flexible reaction vessel, and a frangible activator vessel. Bending the outer tube causes the activator vessel to rupture and cause an exothermic reaction.

A heating device includes a flexible housing that defines a plurality of heater segments. Each heater segment includes a first compartment containing a first reactant, a second compartment containing a second reactant, and a frangible seal between the first compartment and the second compartment. The first reactant and the second reactant are configured to react exothermically upon contact with one another.
