A monolithic weighing system (100) includes a plurality of levers (120), which are joined together by thin-section joints (110). The levers, on the one hand, and the thin-section joints, on the other hand, are made of different materials or material combinations; and the levers, adjoining one of the thin-section joints on both sides thereof, have a first material (21), and the thin-section joint has a second material (22) which is different from the first material. An associated method includes (i) an additive manufacturing process, in which different materials, including the first and second material (21, 22), are applied in layers and are joined to form a single-piece weighing system blank (10), wherein the weighing system blank (10) has prospective lever regions (12) and prospective thin-section joint regions (11), and (ii) subsequent subtractive finishing of the weighing system blank at least on the prospective thin-section joint regions to obtain the weighing system.

Described in detail herein are a system and an apparatus for detecting weight in cart. A display and reader coupled to a cart can scan and decode a identifier of a machine-readable element associated with a physical object. The cart can transmit the identifier to a computing system the computing system can query the database to retrieve a stored weight of the physical object. The physical object be placed in the basket of the cart and a transducer coupled to the cart and determine the weight of the physical object of the cart. The computing system can determine physical object placed in the basket is the same as the last scanned physical object in response to determining the weight of most recently scanned physical object is within a predetermined threshold of the weight of the physical object in the basket.

The present invention provides a deformation detection sensor which combines a magnetic resin dispersing a magnetic filler in a resin with a magnetic sensor, of which stability of detection property is highly enhanced. The present invention thus provides a deformation detection sensor which comprises: a magnetic resin-containing polymer foam which comprises a magnetic resin, in which a magnetic filler is contained, and a polymer foam in which the magnetic resin is included, and a magnetic sensor that detects a magnetic change caused by a deformation of the magnetic resin-containing polymer foam, wherein the magnetic resin has a convex portion on either a surface facing the magnetic sensor or a surface facing opposite to the magnetic sensor, and its production method.

A magnetized weight and distance measuring assembly and method for demonstrating the inverse square law of magnetism by displaying a change in distance between magnets after applying a weighted member to one of the magnets includes a base and a base magnet mounted the base. A shaft is coupled to the base, and a shaft magnet is mounted to the shaft and is moveable along the shaft when the shaft magnet repels away from the base magnet by a magnetic force. A tube is attached to the shaft magnet to define a receptacle. The receptacle receives a plurality of weighted members, wherein the magnetic force opposes a gravitational force of the receptacle and weighted members such that the receptacle moves upwardly along the shaft when the receptacle receives the weighted members. A plurality of graduation markings is positioned on a panel extending upwardly from said top surface of the base.
