Specification

Description:FIELD OF INVENTION
This invention relates generally to systems and methods of weight measurement. Present invention relates to multiple weight sensors encapsulated in a case, for measurement of diverse products and method of operation of the weight measurement system.

BACKGROUND OF THE INVENTION
Weighing scales come in various forms with different purposes and uses. Like many sensors, weight sensors are available in many different forms or types. Each type of weight sensor has features that make them well suited to different applications.
Weight sensors are a device used to measure force and load. They convert weight into an electrical signal which can be processed and used within various applications. There have been proposed weighing machines of new type capable of indicating weight in a digital manner which replaced the prior art according to which weight is visually indicated by means of a fixed scale plate in cooperation with a rotary pointer adapted to rotate in response to the weight or a rotary pointer adapted to rotate in response to the weight associated with a fixed pointer.
In one type of such weighing machine, i.e., a digital weight control including a differential transformer and a strain gauge used as a sensor, displacement (voltage) representative of weight is converted to a digital amount through an A/D converter and a mechanism of for transmitting the weight to the sensor has to be adjusted for correction of linearity in order to maintain linearity of an output voltage of the sensor with respect to the weight.
US20160252390A1 disclosed A multi-function smart scale has a single surface platform. The platform has two or more regions for receiving items to be weighed. Each of the regions has at least one weight sensor dedicated to the region. Each of the sensors and one or more displays are in communication with the microprocessor, such that the microprocessor is configured to provide an independent data analysis for each of the two or more regions that can be displayed for the user.
A user can input data into the scale using an integrated or remote keypad. Additionally, and or alternatively, the scale can receive data from the user through the use of voice or image recognition software. The scale can serve as a mobile unit. Alternatively the scale can be integrated into a work/cooking/food preparation surface, or the entire work/cooking/food preparation surface can serve as the platform.
US7454978B2 disclosed a strain sensor includes a load carrying body configured to strain in response to a load applied along a load path. The sensor further includes a magneto strictive electrical conductor affixed to the body but out of the load path. Application of the load causes the body to strain, which in turn results in a proportional stress being imparted to the magneto strictive conductor, altering its magnetic permeability. A circuit is electrically connected to the conductor to detect such changes in permeability, which are indicative of the applied load.
US4191268A disclosed a weighing machine wherein a mechanical change corresponding to weight of a body to be measured is taken out as an electric signal thereby to provide digital indication of the weight comprises a base body, a metering spring, a load supporting link associated with the metering spring and movable to displace the metering spring in response to the weight, a fixed electrode plate consisting of an electrically conductive flat plate secured to the base body, a movable electrode plate interlocked with the load supporting link and consisting of an electrically conductive flat plate intended to provide capacitance between the fixed and movable electrode plates and a digital indication and processing circuit for detecting change in the capacitance to provide digital indication of the weight.
The digital indication and processing circuit comprises preferably an oscillator including capacitance as a component of an oscillating time constant and a converter for converting the change in oscillating frequencies of the oscillator to a digital amount representative of the weight.
Accordingly is provided a versatile weight measurement system, which integrates multiple Bluetooth weight units and measures multiple weights using multiple sensors.
