A plateware device with an active temperature control system can have a double-walled body with a top metal panel and a bottom metal panel spaced from the top metal panel to define a cavity therebetween. A base (of metal or plastic) can be attached to the bottom metal panel to close the cavity. An outer surface of the doubled-walled body can have a ceramic coating so the plateware device resembles a conventional plateware device. The temperature control system can be disposed in the cavity and can include one or more heat transfer elements in thermal communication with a bottom surface of the top panel to heat at least a portion of the top panel, and control circuitry configured to control operation of the one or more heat transfer elements. The control circuitry is optionally further configured to wirelessly communicate with a mobile electronic device, the control circuitry configured to control the operation of the one or more heat transfer elements based at least in part on information it receives from the mobile electronic device.

Heating unit is constructed according to the embodiments of invention to provide heating or warming features to maintain specific food temperature.

In addition, safety control unit is provided to either adjust or shut down the system should the value deviate from the range value.

Some embodiments provide a microwaveable vessel that can quickly and evenly heat or cook different types of food. In some embodiments, the vessel includes a metallic body adapted to hold food or drinks. The outer portion of the body is coated with a layer of heat-generating glaze. In some embodiments, the vessel also includes a heat-resistant outer cover that covers the heat-generation layer. The vessel of some embodiments has a multi-layered structure with inner and outer shells that are joined together to form a cavity between the shells.

A securable plate for infants having a sidewall projecting a length of a perimeter edge engages removably with a support surface using a suction cup. An opening in the sidewall provides a passage to lift the edge of the suction cup to disengage the suctioned engagement of the suction cup by lifting the edge of the suction cup or a release flap extending from it.

An actively heated mug has a body with a chamber that can receive and hold a beverage and a heating element to actively heat the chamber, batteries, and circuitry that controls the operation of the heating element. A user interface is electrically connected to the circuitry and has one or more buttons actuatable a) to turn on the heating element, b) to adjust a temperature setting to one of multiple temperature settings to control the operation of the heating element to heat or maintain the liquid at a user selected temperature setting, and c) to turn off the heating element.

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.

A food storage system includes a plurality of bowls, a connection element configured to couple to at least two of the bowls, and a protection element configured to couple to the connection element. When two bowls are nested and coupled to the connection element, a void is formed between the two nested bowls and a refrigeration element is positionable in the void to maintain a predefined internal temperature in the food storage system.

A capacitive sensing system for the detection and quantification of food products disposed within a food warming drawer or food storage container is disclosed and comprises an electrically grounded metal plate, and a printed circuit board (PCB) having a plurality of capacitive sensing pads disposed thereon and which effectively serve as capacitive sensors capable of detecting and measuring the capacitance of an object in proximity to it. The system, in conjunction with known detection circuitry, outputs or generates digital number signals which are indicative of the capacitance of the items or food products disposed within the food warming drawer or storage container. The system can therefore be utilized to detect the presence and number of food items disposed within the food warming drawer or container, as well as whether or not the food items are disposed within a vertically stacked array or disposed in a side-by-side array. The system is adapted to be utilized within the food industry as a means for knowing how many food items are present and ready to be used to fulfill patron food orders.

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.

A pouch (100) filled with phase-change material, wherein the pouch comprises a preformed first wall (110) and a second wall (120), wherein the first wall comprises a bowl-shaped part, in which the phase-change material is accommodated, and a peripheral part, wherein the second wall is attached to the peripheral part of the first wall, wherein a high vacuum prevails in the pouch, and wherein the pouch is intended for placing against a wall to be heated or cooled.
