Systems and methods of detecting, identifying, and classifying objects positioned on a shelf are provided. In one exemplary embodiment, a sensor pad comprises a plurality of electrical contacts disposed in the pad as a matrix of rows and columns of electrical contacts. Further, each contact corresponds to a different surface area of the pad and has a first electrical conductor positioned on a first layer and a second electrical conductor positioned opposite to the first conductor on a second layer. Also, at least one of the first and second conductors is operable to vary in resistance or capacitance based on an amount of pressure applied to that conductor. In addition, each contact is configured to enable an electrical connection between the first and second conductors with a resistance or capacitance that varies based on an amount of pressure applied to a corresponding area of the pad when an object is positioned on that pad.

A weight-limiting roadblock device according to the present invention includes a body, wherein the body is provided with a weight detection device, the weight detection device includes a push rod, and the left side of the weight detection device is also provided with an overweight warning device. The overweight warning device includes a railing. The present invention is provided with a putter to detect moving vehicles to avoid the loss of electrical energy caused by the use of sensors. The device also has a roadblock to intercept vehicles that forcibly break through the railings and prevent illegal vehicles from forcibly passing through. The left side of the roadblock is also equipped with an elastic baffle to protect the vehicle being intercepted to prevent safety accidents such as rollover due to interception. This device has accurate measurement, obvious interception effect, and no hidden dangers. It is suitable for many Kind of traffic intersection.

Smart containers or jars are devices that will be used to keep track of various parameters regarding the food stored in them like the weight, count, food quality, nutritional facts, expiry date, minimum order level and all other food related parameters. These devices work as ordinary jars with enablement to track the food related parameters mentioned above. These devices will be equipped with a micro-computer which will be connected to a wireless or Cabled Internet of the user's premises and in turn update the food related parameters to a web application which comes with this device. The data is then processed in the web application and alerts are sent to a mobile device of the user on the various food related parameters.

The present disclosure relates to system(s) and method(s) for monitoring material within a storage jar. In one embodiment, the method comprises receiving a first signal and a second signal from one or more accelerometer coupled to a storage jar and obtaining first data associated with a weight of a material within the storage jar, second data associated with one or more parameters of the environment within the storage and outside the storage jar, a historical data of previous weight measurements. The method further comprises computing a creep associated with the load cell based on the second data and the historical data. The method furthermore comprises computing an actual weight of the material within the storage jar based on the creep and the first data, thereby monitoring material within the storage jar.

A changing table is detachably installed on a play yard and capable of weighting a child. The changing table includes a frame, a weighting module and a fabric component. The frame includes a lower frame and an upper frame. The lower frame is detachably installed on the play yard. The upper frame is movably installed on the lower frame. The weighting module comprises four load sensors disposed on four corners of the frame and between the lower frame and the upper frame. The fabric component covers the upper frame to form a supporting area for supporting the child. The changing table can measure a first weight of the child before feeding the child and further measure a second weight of the child after feeding the child, so as to determine a difference of the second weight and the first weight of the child as the feeding intake.
