A bottle having a water volume measuring function comprises a bottle-lid, a bottle-body, and a measure module disposed in the bottle-lid which comprises at least a micro controller unit, a memory unit and a sound wave transceiver unit. The memory unit stores a lookup table with corresponding relationships between a plurality of frequencies and remained water volumes in the bottle-body. The sound wave transceiver unit emits sound waves with sweeping frequencies towards the bottle-body and receives reflected waves. The micro controller unit determines if any frequency of the sound waves is an air-resonance frequency according to the energy level of each of the reflected waves. When a sound wave frequency is determined as an air-resonance frequency, the micro controller unit obtains the corresponding remained water volume by checking with the air-resonance frequency in the lookup table and users can view the remained water volume without opening the bottle-lid.

An active foodware system includes a mechanical structure and provides visual stimuli, heating of food, and wireless communication by having a power source, a visual stimulating component, a heating component, and a wireless communication component. Other components can provide sensing, data processing, as well as auditory and haptic stimuli. The mechanical structure can be a single unit where the components and circuitry are all contained in the unit and protected from water, or can be two units: an upper food surface for receiving food, and an underplate comprising components and circuitry.

A beverage vessel includes: a beverage container in which a beverage may be stored said beverage container having an upper opening by which beverage may be poured in and poured out of the beverage container and a wall extending from the opening to the bottom of the beverage container; a closure element adapted to be positioned in the upper opening of the beverage container; a light distribution element arranged at the closure element; and a light emitter positioned such that the light emitted by the light emitter passes at least a part of the volume of the beverage container before entering the light distribution element; wherein said closure element comprises a locking mechanism, said locking mechanism comprising at least three locking arms extending in radial direction of the beverage vessel to the beverage container, wherein each arm of the locking element comprises an elastic portion being elastic in the radial direction of the beverage vessel; the beverage container comprises at least one concave portion in the wall, said concave portion extending in radial direction of the beverage vessel; and said arms releasably engage in the concave portion in the wall for releasably locking the closure element to the beverage container.

The invention discloses portable beverage vessel for storing beverage to be consumed by a human, having a beverage container in which the beverage is stored; and an electronic device having a vessel controller, a transmitter and a receiver, said vessel controller being adapted to communicate with a beverage dispenser by exchanging messages using the transmitter and receiver of the electronic device; wherein the vessel controller is adapted to send an identification message to the beverage dispenser, by which the beverage dispenser can identify the portable beverage vessel. The invention also discloses a communicating between the portable beverage vessel and a fluid dispenser and a personal electronic device.

An active foodware system includes a visual-stimulating component for displaying information related to a plurality of sensing components, such as load cells, sensing weight of food on respective dining surfaces of supporting dining plates. A mechanical structure supports and positions the dining plates in a constrained relationship to each other, and cavities in the mechanical structure may unattachedly mate with the dining plates. A wireless communication component wirelessly sends weight data to the visual-stimulating component, such as a mobile phone or tablet computer. The system is configured to determine calories of the food, and the system may include a camera for sensing the food or a diner. The visual-stimulating component may display information other than information provided by a scale, and auditory and haptic stimuli may also be provided.

An intelligent measurement cup comprises a cup body and a cup cover with an electronic module. The electronic module comprises a battery, a main control circuit board electrically connected to the battery, and a laser detection unit electrically connected to the main control circuit board. The laser detection unit comprises a laser probe and a transparent shielding sheet positioned to face the cup body. The cup cover has a corresponding through hole aligned with the laser probe to allow its light to pass through. The emitted laser is configured to penetrate the shielding sheet and scatter into the cup body, to thereby generate sufficient feedback photons. The spectra reflected back through different emission media are different, therefore, the conditions of a liquid, conditions comprising the remaining amount, the type, whether the liquid has deteriorated, etc., in the cup body can be accurately detected.

A container for storing a liquid for consumption. The container may comprise temperature and volume sensors, processors, energy source and a communication device to transmit the recorded temperature and volume data to a remote human interface. The container may also provide for various notifications and alerts to the user if the data falls outside predetermined variable ranges.

A container is provided with a lid having a removable thermometer for measuring the temperature of liquids in the container. A gasket is provided to secure the thermometer to the lid and maintain a hermetic seal between the thermometer and the gasket and between the gasket and the lid. The gasket is resilient to maintain the hermetic seal when the thermometer is subjected to torque or other stresses such as may occur when the lid is attached or detached from the container.

A dining plate unit includes a visual stimulating component to provide light emanating from the dining plate unit, means for sensing various conditions related to the dining plate, and/or means for wirelessly communicating the sensed data, means for wirelessly transferring power, or means for generating sound. The dining plate unit can be a single component where the device and related circuitry are all contained in the unit, or it can be at least two components: an upper translucent dining plate, and a mating underplate including the devices and circuitry for directing light through the upper translucent dining plate.
