A plate delivery system provides storage for plates in a first-in, last-out configuration. As the kitchen staff completes a meal (plated), the plate is presented to a staging area of the plate delivery system. The plate is moved into a storage area to be ready for the next plate at the staging area. After a number of plates are stored, the plate delivery system relocates from the kitchen to the eating area (e.g., restaurant table or banquet table) and each plate is sequentially presented by a delivery mechanism (e.g., telescoping arms, a robot, or a waitperson) for delivery to the table. In some embodiments, the plate delivery system is enclosed and has a cover mechanism. In some embodiments, the plate delivery system has telescoping arms with fingers for moving the plate from the staging area to the table.

An actively heated or cooled mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed at least partially in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A user interface is electrically connected to the circuitry and has one or more selection members actuatable a) to turn off the one or more heating or cooling element or b) to adjust a temperature setting to one of multiple temperature settings configured to control the one or more heating or cooling elements to heat or maintain the liquid at a user selected temperature.

An actively heated or cooled cup or mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A sensor can detect a presence of a liquid in the chamber, the circuitry configured to turn on power to the heating or cooling elements after said liquid is detected and further configured to automatically turn off power to the heating or cooling elements upon receiving a signal indicating that the liquid in the chamber has dropped below a predetermined liquid level or been depleted completely.

A food warming system involving a heat sink component, a warming plate, and an intervening insulation and heat- or fire-resistant layer that moderates the flow of heat from a charged heat sink component to the warming plate on which a vessel containing food is placed to maintain food in a heat-regulated state.

An actively heated or cooled food container can have a lid movable between an open and a closed position and an insulated body to which the lid can be attached. The insulated body can have a sidewall that defines a perimeter of the container body and a base, the sidewall and base defining one or more chambers that can be sealed by the lid. The food container can have a temperature control system that can include one or more heating or cooling elements in thermal communication with one or both of the sidewall and the base and operable to heat or cool one or both of the sidewall and the base to thereby heat or cool the one or more chambers in the food container.

An actively heated mug, travel mug, baby bottle, water bottle or liquid container is provided. The mug, travel mug, baby bottle, water bottle or liquid container can include a body that receives a liquid therein and a heating or cooling system at least partially disposed in the body. The heating or cooling system can include one or more heating or cooling elements that heat a surface of the receiving portion of the body and one or more energy storage devices. The mug, travel mug, baby bottle, water bottle or liquid container can include a wireless power receiver that wirelessly receives power from a power source and control circuitry configured to charge one or more power storage elements and to control the delivery of electricity from the one or more power storage elements to the one or more heating or cooling elements. The mug, travel mug, baby bottle, water bottle or liquid container also can have one or more sensors that sense a parameter of the liquid or sense a parameter of the heating or cooling system and communicates the sensed information to the control circuitry. The control circuitry can turn on, turn off, and/or operate the heating or cooling element to actively heat or cool at least a portion of the body to maintain the liquid in a heated or cooled state generally at a user selected temperature setting based at least in part on the sensed parameter information. The mug, travel mug, baby bottle, water bottle or liquid container can also be paired with a remote device or mobile electronic device to send or receive communications or commands.

The present invention relates to a dish warming system that includes a plurality of dish warming assemblies each having a plate with a power source and a heat element. The power source of each dish warming assembly allows for the concurrent charging of the plurality of dish warming assemblies while stacked. The heat element in some iterations of the system includes a pressure switch that activates the heat element when a dish is placed on the dish warming assembly.

An actively heated or cooled mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed at least partially in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A user interface is electrically connected to the circuitry and has one or more selection members actuatable a) to turn off the one or more heating or cooling element or b) to adjust a temperature setting to one of multiple temperature settings configured to control the one or more heating or cooling elements to heat or maintain the liquid at a user selected temperature.

An actively heated drinkware container includes a vessel with a chamber that receives and holds a volume of liquid. The drinkware container includes a heating module with a first heating element operable to heat one portion of the chamber and a second heating element operable to heat another portion of the chamber, the second heating element spaced from the first heating element. Operation of the first and second heating elements generates a circulation current in the volume of liquid in the chamber that mixes the liquid and diffuses a temperature of the liquid to thereby reduce temperature stratification of the liquid in the chamber and so that a temperature of the liquid throughout the volume of liquid in the chamber is approximately uniform.

An actively heated or cooled cup or mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A sensor can detect a presence of a liquid in the chamber, the circuitry configured to turn on power to the heating or cooling elements after said liquid is detected and further configured to automatically turn off power to the heating or cooling elements upon receiving a signal indicating that the liquid in the chamber has dropped below a predetermined liquid level or been depleted completely.
