This invention relates to quantifying dietary intake, particularly relating to connected tableware and systems for quantifying dietary intake. In particular, the invention relates to the measurement of food quantities placed on tableware and thereby determining the dietary intake of the user.
A common task for health conscious people is to quantify and track their dietary intake in the form of calories and other relevant nutritional facts. The current methods for quantifying calories are sufficient in the method of correlating a certain amount of something to a specific number calories but severely lack in the method for obtaining the specific amount of food or beverage that is being eaten or drank. Current methods that exist include the use of food scales and eating premeasured packaged foods. Current methods are limiting in the type of foods that can be eaten and where those foods can be eaten.
The invention aims to provide connected tableware for quantifying dietary intake of a user. The connected tableware is comprised in the form of various tableware items (i.e. plate, cup, bowl, bottle, etc.) that comprise added electronics capability. The added electronics capability of connected tableware comprises a data processing unit for storing and processing data and a transceiver for transmitting and receiving data.
Food or beverage is placed in the respective connected tableware item, wherein the amount of said food or beverage is measured. The user then identifies the food or beverage present and the nutritional content of the food or beverage is calculated. Additionally, if the meal is completed with food or beverage remaining, the user can perform the measurement and identification steps again to determine a more accurate nutritional intake.
Accordingly several advantages are to provide connected tableware, to provide a means for quantifying dietary intake, to provide an improved method for determining caloric intake, and to provide a means for easily delivering food quantities to common devices used for tracking caloric intake. Still further advantages will become apparent from a study of the following descriptions and the accompanying drawings.
The connected tableware for quantifying dietary intake is encompassed in a plurality of embodiments that shall be discussed in the present section.
A plurality of embodiments comprises tableware, wherein tableware includes dishes, bowls, cups and bottles. Tableware is used for holding food and beverages, broadly dietary intake, for consumption by a user. Tableware provides the user with the opportunity to quantify his/her dietary intake prior to consumption. Thus, tableware provides the user with the optimum interface to quantify dietary intake prior to consumption without changing dietary sequences, as is required with the use of a food scale. Inherently, common tableware does not contain the capability to capture and process data about the dietary intake it holds. Therefore, the integration of technological advancements is required to provide the capability to capture and process data.
Consequently, the tableware of the present invention comprises a data processing unit 127 having at least one collector, a storage medium, and at least one processor, wherein the collector, storage medium, and processor, respectively, collect, store, and process data. Accordingly, the data processing unit 127 is chosen from the group microprocessor, microcontroller, field programmable gate array (FPGA), digital signal processing unit (DSP), application specific integrated circuit (ASIC), programmable logic, and combinations thereof.
Additionally, in some embodiments, the collector of the data processing unit 127 is an electrically conductive wire, wherein the electrically conductive wire receives the electrical output of various sensors.
Moreover, the storage medium of the data processing unit 127 is comprised of volatile memory and non-volatile memory, wherein volatile memory is used for short-term storage and processing, and non-volatile memory is used for long-term storage. Accordingly, volatile memory is chosen from the group random-access memory (RAM), dynamic random-access memory (DRAM), double data rate synchronous dynamic random-access memory (DDR SDRAM), static random-access memory (SRAM), thyristor random-access memory (T-RAM), zero-capacitor random-access memory (Z-RAM), and twin transistor random-access memory (TTRAM). Non-volatile memory is chosen from the group read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), flash memory, ferroelectric random-access memory (FeRAM), magnetoresistive random-access memory (MRAM), phase-change memory (PRAM), conductive-bridging random-access memory (CBRAM), silicon-oxide-nitride-oxide-silicon memory (SONOS), resistive random-access memory (RRAM), racetrack memory, nano-random-access memory (NRAM), and Millipede memory.
The processor of the data processing unit 127 is chosen from the group microprocessor and micro controller.
Additionally, the connected tableware for quantifying dietary intake comprises at least one data transmitter 134, such that the data can be transmitted to be used by another medium and data can be received from another medium. The data is packaged as at least one signal and transmitted to another medium.

Often, the segmented configuration of the weight sensing system comprises a plurality of weight sensors, commonly referred to as scales, wherein at least one weight sensor is comprised within each segment of the device. Accordingly, at least one weight sensor is utilized to measure the weight of a certain segment that contains a certain substance, which allows the user to calculate the caloric content of the item based on its weight and existing data that correlates caloric content to weight. The segmented configuration enables the user to easily portion an entire meal within the segments of the device while quickly and accurately obtaining the weight of each item that will be consumed, thus allowing for the calculation of caloric content for the user's dietary intake.
The weight sensor of the segmented configuration of the weight sensing system is chosen from the group strain gage, electronic analytical scale, capacitive scale, and any combination thereof. Commonly, a strain gage is comprised of an insulating flexible backing with a metallic foil pattern affixed and is attached to the object to be measured in a proper place with an adhesive, such as cyanoacrylate. As a load is applied to the object, the object deforms causing the foil of the strain gage to deform that results in an electrical resistance change, which is typically measured using a Wheatstone bridge. The resistance change is converted into a strain value using a gage factor and the strain value is used to calculate the load on the object, which provides the weight of the item providing load on the object.
An electronic analytical scale measures the load on an object by countering the load applied using an electromagnet to generate a force. The measurement of the counter force applied by the electromagnet and the electromagnet itself are often comprised in an electromagnetic force restoration sensor.
A capacitive scale comprises a capacitive sensor that is constructed from two parallel conductive plates separated by an insulator such that, in the active portion of the sensor, the insulator allows for an air gap between the parallel plates. Forces acting perpendicular to the plane of the parallel plates in the active region deform one or both conductors. Accordingly, the parallel plates move closer together or further apart due to deformation, thus, changing the capacitance of the sensor. The change in capacitance is scaled by a reference factor that provides the weight of the item causing the capacitance change.
An open configuration of the weight sensing system resembles a normal tableware item such that the holding surface of the item is indistinguishable from a typical tableware item, essentially lacking barriers. The user places dietary items on the plate as normal without regard for segmentation. A weight sensing system having an open configuration comprises a network of weight sensors such that the weight of dietary items dispersed across the holding surface can be measured.
Optionally, a weight sensing system having an open configuration is comprised of a network of strain gages, wherein strain gages are optimally placed throughout the underside of the holding surface and each strain gage has an associated position relative to a reference point. The dispersed dietary items create concentrated loads along the holding surface of the connected tableware. The network of strain gages operates in conjunction with the data processing unit to identify the position of dietary items that create concentrated loads and measures the weight of the concentrated load on the holding surface. Thus identifying individual weighing individual dietary items dispersed throughout the holding surface.
In further options, a weight sensing system having an open configuration is comprised of a network of capacitive scales and operates under the same principles as the previously described network of strain gages to determine the position and weight of concentrated loads.

A displacement level gauge comprises a column of solid material (a displacer) that is suspended in the holding area of the tableware. As the fluid volume in the holding area increases, a buoyant force pushes up on the displacer. The displacer is calibrated to be displaced when the fluid volume changes. As the displacer is displaced, it changes the force exerted on a force transducer that has consistent contact with the displacer. The changes in the force exerted by the displacer correspond to changes in dietary fluid level.
Optionally, at least one strain gage is affixed to the underside of the holding area such that distortions in the holding area are quantitatively measured. As the fluid volume increases, the force applied to and thus distortion exhibited by the holding area increases. The changes in the force measured by the strain gage correspond to changes in dietary fluid level.
A capacitance transmitter comprises either an insulated rod connected to a transmitter and the fluid, or an uninsulated rod attached to a transmitter and the reservoir wall. As the volume of fluid changes, the overall capacitance introduced by the rod changes proportionately. A capacitance bridge measures the capacitance of the rod and is calibrated to correlate specified capacitances to dietary fluid levels.
A magnetostrictive level transmitter comprises a sensor wire, piezoceramic sensor, transmitter, and magnetic float. The sensor wire runs through the center of the magnetic float and is attached to the piezoceramic sensor. The fluid level is detected by the transmitter sending a short current pulse down the sensor wire, which sets up a magnetic field along the length of the sensor wire. A timing circuit is also triggered on when the pulse is sent. The magnetic float reacts to the magnetic field and produces a torsional force in the sensor wire. The torsional force is detected by the piezoceramic sensor which sends out a varying electric signal dependent on the fluid level.
An ultrasonic level transmitter comprises a transducer and timing circuit. The transducer transmits ultrasound to the surface of the fluid. The timing circuit measures the amount of time it takes the ultrasound wave to travel back to the transducer. The amount of time corresponds to fluid level of the holding area. A radar level transmitter operates in the same manner as the ultrasonic level transmitter with exception of transmitting microwaves, which are reflected from the fluid surface.

Optionally, the fat content sensor 718 utilizes the method of near-infrared interactance comprising at least one infrared emitter and at least one photo detector. A beam of infrared light is transmitted into the dietary item. The infrared light is reflected by non-fatty matter and absorbed by the fatty matter. The photo detector captures the reflected infrared light. The ratio of the infrared light returned to the photo detector to the infrared light emitted by the infrared emitter is correlated to the percentage of fat content in the dietary item.
Further variations of the fat content sensor 718 include electrical impedance analysis comprising at least two conductors. A small electric current is sent through the dietary item and the resistance between the conductors is measured. The resistance is correlated to fat content percentage of the dietary item. In general, fat is anhydrous and a poor conductor of electric current. Conversely, non-fatty matter, water, and electrolytes are good conductors of electric current.

Optionally, the temperature sensor 810 further comprises at least one protrusion that extends from the holding surface of the connected tableware such that the protrusion can be inserted into dietary items to obtain said dietary item's internal temperature. Often, the protrusion is an extension of the temperature sensor such that the temperature sensor 810 is located at any point in contact with the protrusion including the distal tip of the protrusion. Further, the protrusion can be retractable, wherein it extends beyond the holding surface of the connected tableware only when a temperature measurement is being taken.
