[0067] The present invention, in some embodiments thereof, relates to an electronic measuring utensil (e.g., tray, spatula, scoop, spoon, etc.) and, more particularly, but not exclusively which may convey information to and / or from a user and / or a network system (e.g., how much to weigh, how much was weighed, when a desired weight is reached, etc.).

[0068] OVERVIEW

[0069] An aspect of some embodiments of the current invention relates to an accurate electronic measuring utensil, and more particularly, but not exclusively, which may measure weight, volume, etc. According to some embodiments, the electronic measuring utensil may convey information to and / or from a user and / or a network system.

[0070] In some embodiments, the electronic measuring utensil is configured to be held by hand. For example, the utensil may include a handle. Optionally the handle may be detachable and / or may be fixed to the blade of the utensil. The blade may optionally include a bowl and / or a pan (e.g., with one or more open sides) and / or spatula and / or a scoop and / or a fork). Optionally, an electronic weighing system weighs the contents supported by the blade (e.g., in the scoop and / or on the pan). Sensors may be mounted to the blade and / or the handle and / or between the blade and handle (e.g., on a base of the blade). For example, the handle may include a handgrip 101 and / or be configured for holding the utensil with one hand. The sensors and processor are optionally configured to give an accurate estimation of properties of the contents of the blade (e.g., it’s mass) while be held by hand at an imprecise angle and / or not completely still.

[0071] In many industries, for example the food industry, the weight of both the ingredients and of the portions served is a critical factor in the cost of the products. For example, in order to produce a food product having the same flavor and texture reproducibly relies on knowing the precise weight or volume of the ingredients used. Additionally or alternatively, customers buying produce such as, herbs, spices, dry ingredients, wet ingredients, meat, fish, poultry, etc., are usually charged by weight or volume. Further, deli counters, fresh food markets and many restaurants charge by weight or volume for their products. Many other industries also require precise measurement of various parameters of the starting materials or products. However, measurement by quantity, mass and / or volume tends to be time consuming, and imprecision may be costly. Additionally, scales and other measuring devices tend to be difficult to transport and may require careful handling to ensure that their accuracy is maintained.

[0072] In some embodiments, measurement may require a user to look at an order report and / or other document that may present the desired measure, the user may then need to fill a container and / or weigh the container and / or then add or subtract goods and / or articles from the container until the desired amount is reached, the user may then need to report the amount that in the container to the cashier.

[0073] For example, a restaurant may have a system where a customer orders food and / or drinks at a table and / or at the counter. The restaurant may then send the order report to the kitchen to make the order. The cooks may then read the order and use various containers and / or scales to measure the right amount of food to be provided to the customer.

[0074] In some embodiments, there is a provided a rapid, easy to use, portable device for measuring the parameters of materials, e.g., quantity, mass or volume of food produce and / or food products.

[0075] According to some embodiments, various items and / or goods may be sold and / or arranged according to a desired weight and / or a desired volume and / or other desired size measurements. Optionally, a user may use an electronic utensil and / or a handling device and / or a measuring device to identify when a desired weight and / or volume may be reached. Optionally, there may be various actions that may need to be undertaken to measure the various items and / or goods and / or articles properly.

[0076] According to some embodiments, the current invention is a system that may enhance efficiency in processing and / or measuring and / or delivering goods and / or products. An embodiment of the current invention may include an electronic utensil that may be portable and / or may function to measure products and / or goods. For example, an electronic utensil may be configured to measure mass and / or volume and / or quantity and / or length and / or other measurements.

[0077] Additionally, or alternatively, according to some embodiments, an electronic utensil may include a system for communicating with a user, for example, a screen to display a determined measurement, and / or lights (such as LEDs), and / or sounds (such as from speakers). For example, an electronic utensil may communicate various details about the content of the electronic utensil to a user, such as the volume and / or weight, etc. of the contents. Optionally, the electronic utensil may include a user interface, e.g., one or more buttons, a touch screen, etc. Optionally, the user may input data to the electronic utensil, e.g., the desired amount of a product, good or item, the cost per unit of a product, good or item, etc. Optionally, the electronic utensil may be preprogrammed, e.g., with the cost per unit of a product, good and / or item, etc. Optionally, the electronic utensil may be programmed to convert one form of measurement to and / or from another form of measurement, e.g., the weight of a known liquid to its corresponding volume, etc. Optionally, the user may be a skilled user, e.g., a chef, kitchen user, shop assistant, laboratory user, pharmaceutical dispenser, etc. and / or the user may be unskilled, e.g., a shopper, etc. Optionally, such an electronic utensil may make the measuring of goods and / or food and / or products and / or produce more efficient, and / or more accurate, and / or faster.

[0078] In some embodiments, the electronic hand-held utensil may connect to a network to receive and / or send information to other devices (for example, cell phones, cash registers, waiter held devices etc.). For example, it may be used in restaurants to help kitchen staff measure food portions and / or to charge customers for food based on the actual weight of the food.

[0079] In some embodiments, the invention includes a versatile and efficient system for measuring and delivering goods and products. Optionally, the system may be used in a variety of settings, including restaurants, grocery stores, and laboratories. In some embodiments, the electronic hand-held utensil may be programmed to meet the specific needs of the user. Optionally, the utensil may facility efficiency and accuracy of operations in those settings. Alternatively, or additionally the system may be used by individuals who want to measure and track their food intake. Additionally, or alternatively, an embodiment may include a system in which the electronic utensil may connect to a network (e.g., a local network and / or an Internet network) and / or may receive information and / or convey information to various other parts of a network. For example, an embodiment may be designed for a restaurant that food orders may be sent (e.g., by wi-fi) from a cash register and / or ordering station to the electronic utensil being used by the kitchen staff and / or the electronic utensil may help the kitchen staff to measure the desired portions (e.g., by signaling to them what to measure / add / subtract, how much to measure / add / subtract, and / or when they have reached the correct measurement) and / or the electronic utensil may send a report to the cash register and / or to a waiter that the food is ready and / or the actual weight or the food. Optionally, the customer may then be charged accordingly.

[0080] According to some embodiments, the electronic utensil may be of various sizes, and / or shapes. For example, the electronic utensil may be large (e.g., for measuring bulk foods, such as dry ingredients, food portions, fresh produce, etc.) and / or small (e.g., for measuring spices and / or medicine, etc.). Optionally, the system may be used for large and / or small and / or medium objects (e.g., bulk food, restaurant portions, spices, medicine, etc.). Optionally, the electronic utensil may be scoop shaped (e.g., for dry ingredients, spices, sweets, shawarma, etc.), and / or tray shaped (e.g., for liquids, meat, fish, poultry portions, vegetables, etc.) and / or cup shaped (e.g., for liquids, dry ingredients, etc.), and / or other shapes. Optionally, the amount of produce may be large, and / or medium, and / or small. Optionally, the produce may be solid, semi-solid, liquid, powder, or any combination thereof. Optionally, the electronic utensil may be configured to facilitate attachment of various shaped blades (e.g., spatula blades and / or containers to be reversibly attached and / or detached, e.g., depending on the item, good, product, and / or produce being measured. Optionally, the electronic utensil may be configured to interchangeably attach and / or detach various containers of various shapes and / or sizes. Optionally, the electronic utensil may be portable. Optionally, the electronic utensil may be handheld. Optionally, an electronic utensil may have a handle.

[0081] According to some embodiments, the electronic utensil may include multiple load sensors, an accelerometer, and / or a gyro. Optionally, such sensors may be coupled to a processor e.g., to make allowance for movement of the electronic utensil and / or variations in the position of the object being weighed and / or the angle of the electronic utensil relative to gravity, for accurate measurement in various cases.

[0082] According to some embodiments, the electronic utensil may include one or more strain gauges. Optionally, the electronic utensil may sample and / or take a measurement from the one or more strain gauges continuously and / or intermittently and / or when instructed to do so. Optionally, a strain gauge may measure pressure and / or a force applied on the electronic utensil, e.g., by the contents in the electronic utensil.

[0083] For example, the pre-determined angle relative to the floor may be set to be parallel to the floor (0°), perpendicular (90°) to the floor and / or any angle within the range between 0° to 15° and / or between 15° to 45° and / or between 45° to 60° and / or between 60° to 90° to the floor.

[0084] For example, the pre -determined speed of the electronic utensil may range between 0 to 1 m / s, and / or between 1 to 5 m / s, and / or between 1 to 10 m / s. For example, the pre -determined acceleration may range between 0 to 1 m / s2, and / or between 1 to 5 m / s2, and / or between 1 to 10 m / s2, e.g., the user may be stopped, place the electronic utensil on a surface, be walking and / or place the electronic utensil on a conveyer, etc.

[0085] According to some embodiments, the electronic utensil may include one or more accelerometers and / or gyros. Optionally, the electronic utensil may sample and / or take a measurement from the one or more accelerometers and / or gyros continuously and / or intermittently and / or when instructed to do so. Optionally, an accelerometer and / or gyro may measure an angle of the electronic utensil with the ground (gravity direction), determine if the electronic utensil is moving or not, at a selected time interval, etc.

[0086] According to some embodiments, the instruction to sample and / or take a measurement from one or more sensors may be manual, e.g., by a user. Alternatively, and / or additionally, the instruction to sample and / or take a measurement from one or more sensors may be automatic. Optionally, automatic instruction may occur when the electronic utensil fulfills one or more pre-determined parameters, e.g., when the electronic utensil is held at a pre-determined angle, is moving at within a range of predetermined speeds, is not moving, at a selected time interval, etc.

[0087] According to some embodiments, when one or more signals from one or more sensors fulfdls one or more pre-determined parameters, then the weight of the contents of the electronic utensil may be determined, e.g., when the electronic utensil is held at a pre-determined angle relative to gravity, is moving at within a range of predetermined speeds, is not moving, at a selected time interval, etc. Optionally, an algorithm may determine the weight of the contents of the electronic utensil.

[0088] According to some embodiments, an algorithm may account for various parameters. Optionally, one or more ranges of pre-determined values may be set and / or determined for the various parameters. Optionally, the algorithm may wait until the system meets one or more pre-determined parameters for a measurement. Optionally, until such pre-determined parameters are fulfilled, the system may not make a weight measurement. Optionally, until such pre-determined parameters are fulfilled, the system may not display a weight measurement. Optionally, when one or more pre-determined parameters are fulfilled, the system may rapidly (e.g., within about 1 s, within about 5 s, within about 10 s and / or within about 15 s) make a large number of measurements (e.g., about 10 measurements, about 25 measurements, about 50 measurements, about 100 measurements, and / or about 500 measurements, etc.).

[0089] According to some embodiments, after the initial measurements, the system may sample and / or retake a measurement from the one or more sensors to ensure that after the measurements the pre-determined paraments are still fulfilled. Optionally, if the one or more pre-determined parameters are not fulfilled, the system may not display the data. Optionally, if the one or more pre-determined parameters are not fulfilled, the system may wait for another opportunity to make the measurements when one or more pre-determined parameters are fulfilled. Optionally, if the one or more pre-determined parameters are fulfilled, the system may display the data. Optionally, displayed data may be statistically extracted by an algorithm. Optionally, the displayed data may be a single measurement from the data (e.g., a mean, etc.).

[0090] According to some embodiments, the system may include an indicator which may indicate when the electronic utensil has met and / or has not met one or more predetermined parameters, e.g., is not being held at the correct angle, is not being held steady, is moving, etc. Optionally, the system may include an option for a user to force display of a measurement, even when conditions are not optimal, to provide a provisional inaccurate measurement. Optionally, the system may include a means of setting and / or resetting one or more parameters of the system.

[0091] Some embodiments may relate to a method for using an algorithm to determine the weight of the contents of an electronic utensil. For example, the electronic utensil may include one or more sensors for measuring pressure / force to be connected to a microprocessor, wherein the microprocessor may be configured to perform a measurement in the time when the one or more sensors (e.g., strain gauge, gyro, accelerometer, etc.) indicate that the electronic utensil is stable. Optionally, the one or more sensors may be continuously sampled. Optionally, one or more signals from one or more sensors may be digitized and / or analyzed by an algorithm on the microcontroller. Optionally, when the readings correspond within a defined error interval, the measurement will be translated into preselected units (e.g., milliliters, grams, etc.), and / or the system may provide an indication to the user that one or more pre-determined parameters have been fulfilled (e.g., an indicator light may be green).

[0092] According to some embodiments, the accuracy of the measurement may depend on the transmission of the weight to a strain gauge. For example, there may be a difference if the weight is placed in a comer in the center of the device. Optionally, use of multiple strain gauges and / or an appropriate algorithm may improve the accuracy of the weight measurement after calibration.

[0093] According to some embodiments, the system may be programmed to give measurements at a desired accuracy (e.g., a user may be allowed to choose between a more accurate measurement and / or a quicker and / or easier operation). Alternatively, or additionally, the system may display a measurement and an indication of the accuracy of a measurement. In some embodiments, the system may alert a user when it has made a measurement at a desired accuracy and / or give an audio indicator of the measurement (for example, a voice may alert a user of the weight and / or when a desired weight is reached).

[0094] According to some embodiments, the system may measure pressure and / or force. Optionally, the system may include a strain gauge. Optionally, a processor may run an algorithm to perform the measurement at a time when the system is in a stable state. Optionally, a display may indicate whether the system is sufficiently stable to perform a measurement. Optionally, the system may indicate whether the system is not sufficiently stable to make a measurement.

[0095] According to some embodiments, the algorithm may preform one or more of the following: continuously sample the strain gauge; and / or continuously sample condition sensors (e.g., 3D accelerometer, gyro, etc.); and / or analyze sensor data and indicate is the system is sufficiently stable or not (e.g., visual indication, audible indication, tactile indication, and / or a combination thereof); and / or when the conditions are sufficiently stable to permit measurement, which may correspond to one or more parameters within a pre-defined estimated error, gather sensor data; and / or convert the measurement may to the desired units; and / or provide an output of the measured parameter.

[0096] According to some embodiments, the system may use artificial intelligence to analyze sensor data.

[0097] According to some embodiments, the accuracy of the measurement depends on how well the weight is transmitted to the strain gauge. Optionally, the system may include multiple strain gauges and / or an appropriate algorithm to improve the accuracy of the measurement after calibration.

[0098] In some embodiments, the system detects when conditions (movement, angle to gravity) are conducive to an accurate measurement. Optionally, the user may adjust the accuracy of the measurement and / or when and / or how the measurement is displayed and / or the user is notified.

[0099] In some embodiments, an electronic utensil may be designed for use in the food industry. In the food sales industry (dining and / or fast-food and / or shopping etc.) there may be various foods. Many foods are sold by weight and / or there may be various foods that the norm for selling them may be by estimate.

[0100] An example of a food sometimes sold by estimate may be shawarma. There may be a need to aid in measuring amounts of food and / or measuring quickly without needing to perform an addition action in the production, and / or preparation line, such as putting food on a scale and checking the weight, and / or adding, and / or removing food to obtain to a desired amount. Many business owners who sell foods, and / or users buying, and / or handling, and / or preparing food, may wish to keep track of the weight of the food they are handing (this may a need for handling non-edible substance also). For example, a restaurant may want to increase service speed as much as possible. Specifically, but not exclusively, shawarma restaurants may find it hard to keep track of the amount fed per serving and as a result may have challenges in planning quantities over time.

[0101] Additionally, the challenge of serving a standard amount may interfere in maximizing profits and / or growth of the business. For example, users may be serving too much and / or too little to the customers. In addition, there may be customers who request larger portions of food and / or specific portion sizes (e.g., for children, for specific diets, etc.) and / or specific portion sizes of foods during preparation, and the business owner may not have a system and / or way of pricing this. It may be not worthwhile to place on a scale for the handler of the shawarma (and / or other food and / or substance), to determine the desired amount of meat so that the customer is satisfied and / or that the seller may make a desired profit and / or to increase efficiency and / or accuracy and / or speed.

[0102] Some embodiments of the current invention may relate to a utensil which may include a weight scale function. Optionally, this scale function may be simultaneous to the handling of the product. For example, the scale may show the weight of the content in a blade (e.g., a bowl and / or a scoop and / or container and / or pan) such that the user just needs to glance to see how much the food is. Optionally, a device may contain a lever mechanism that detects the weight change as soon as you lower the content into it. Optionally, a device may have a digital monitor and / or a battery housing. According to some embodiments, the method may be used for large and / or small and / or medium objects (e.g., bulk food, restaurant portions, spices, medicine, etc.). Optionally, the method may include weighing with an electronic utensil, such as a scoop, tray, etc. Some embodiments may be designed to help handle specific foods. For example, the system may be configured for Shawarma (e.g., in a fast-food stand they cut meat off a large piece and serve pieces of meat to a customer) and / or for other foods, e.g., chips, salad, etc.

[0103] In some embodiments, an electronic utensil may include a blade (e.g., a pot and / or scoop and / or a spoon and / or bowl and / or pan) with a weight scale system. Optionally, the scale may be electronic and / or mechanical. Optionally, the scale may detect the weight of the contents of the blade. For example, an embodiment may include a container that may fit into and / or be supported by a base (e.g., another container . Optionally, the system may include a sensor at the bottom and / or side of the base that may detect the weight pressure that is increased by the contents put into the inner (or upper) container. Optionally, the weight may then be displayed. Optionally, there may be an embodiment that the container and / or the bottom of a container is held lower than the measuring device and the measuring device may detect how much pressure is being pulled downwards. In some embodiments, the base and / or container may be shaped to distribute weight evenly even when tipped at an angle. For example, a rounded container may be weighed as it is displaced toward a rounded mount by gravity.

[0104] In some embodiments, the blade supporting the contents are placed may be attached to, and / or may be detachable from, and / or entirely unsecured, and / or permanently connected. Optionally, a blade may be able to support and / or contain, for example, between 0.1 milliliter to 10 milliliters, and / or between 10 milliliters to 100 milliliters, and / or between 100 milliliters to 1 liter, and / or between 1 liter to 5 liters, and / or between 5 liters to 10 liters, and / or between 10 liters to 100 liters. The scale may be able to measure between 0.01 gram to 1 gram, and / or between 1 gram to 100 grams, and / or between 100 grams to 250 grams, and / or between 250 grams to 1 kilogram, and / or between 1 kilogram to 10 kilograms, and / or between 10 kilograms to 100 kilograms.

[0105] In some embodiments, the utensil may have a data screen. Some embodiments may show weight of content and / or angle the utensil is being held and / or other information and / or an indicator when the weight is accurate (e.g., because the angle is proper and / or the device is still and / or because the detected weight is stable [e.g., not changing more than a tolerance over a set period of time]). Optionally, an embodiment may have various control buttons. Optionally, there may be a way to change the 0 setting on the scale. Optionally, an embodiment may have multiple blades and / or various sized containers that may be interchangeable to the device. For example, there may be a need to clean the utensil and / or there may be a method to attach one blade for a period of time and then take it off and / or then attach a replacement blade for a period of time. Optionally, this may aid a user to clean all the blades after use. Optionally, there may be a setting to change the accuracy of the scale. Optionally, a custom scale may be defined. For example, in place of and / or in addition to giving a weight the display may indicate if the quantity is with a serving and / or there may be an indicator of a large serving, a small serving and / or a medium serving and the like (for example each serving and / or dish may have a range of weight etc.). Optionally, the indicator may be textual and / or a colored light and / or a region of a scale, etc.

[0106] In some embodiments a utensil, when held parallel to the ground, may have a depth ranging between 0 to 10 mm deep, and / or between 10 to 50 mm deep, and / or between 50 mm to 1 meter deep. Optionally, a blade may have a width ranging between 0 to 10 mm wide, and / or between 10 mm to 50 mm wide, and / or between 50 to 100 mm wide, and / or between 100 mm to 1 meter wide.

Optionally, a blade may have 1 wall, and / or 2 walls, and / or 3 walls, and / or a bowl and / or more walls.

[0107] In some embodiments, there may be blades for specific foods and / or types of food (e.g., a spatula and / or strainer for collecting French fries and / or other deep-fried foods and / or tongs (e.g., for a barbecue) and / or an ice-cream scoop, soup ladle, etc.). Optionally, there may be a fork shaped device that may connect and act in conjunction with the scale.

[0108] In some embodiments, the system may include multiple blades and / or various sized containers that may be interchangeable to the device. For example, there may be a need to clean the blade and / or there may be a method to attach one blade for a period of time and then take it off and / or then attach a replacement blade for a period of time. This might help a user to clean all the blades after the user is finished with each blade. Optionally there may be a setting to change the accuracy of the scale, e.g., to various decimal places. Optionally, a custom scale may be defined. For example, in place of or in addition to giving a weight the display may indicate if the quantity is within a serving size, and / or there may be an indicator of a large serving, a small serving, and / or a medium serving and the like (for example each serving and / or dish may have a range of weight etc.).
