A shopping cart comprises a basket and a wheeled base. An upper portion of the base has a coupling feature reversibly joined to a lower portion of the basket when the shopping cart is in an assembled, non-weighing configuration. The cart further comprises a weighing kit assembled from a lower frame, an upper frame with a coupling feature that emulates the coupling feature of the upper portion of the base member, and a load-cell assembly that mediates between the upper and lower frames. The lower frame is designed for being reversibly joined to the coupling feature of the base member, whilst the coupling feature of the upper frame of the weighing kit is designed to be reversibly joined to the basket member.

A fire suppressant module according to one example includes a suppressant tank having a body and a base, a counterweight scale disposed in the base, and a data module comprising at least one of a display configured to display a weight of the suppressant tank and processor and a transmitter configured to communicate the weight of the suppressant tank.

A system for refining an item identification model detects a triggering event at a platform. The system captures images of the item. The system extracts a set of features from at least one of the images. The system identifies the item based on the set of features. The system receives an indication that the item is not identified correctly. The system receives an identifier of the item. The system identifies the item based on the identifier of the item. The system feeds the identifier of the item and the images to the item identification model. The system retrains the item identification model to learn to associate the item to the images. The system updates the set of features based on the determined association between the item and the images.

Weighing scale apparatuses (devices and systems) and methods are implemented using a variety of biometric-based devices and methods. According to one such implementation, a weighing scale uses a base unit to integrate a support structure, a display, and circuitry to measure and determine the physiological parameters of the user, including a user-weight metric. The support structure includes a platform region that utilizes sensor circuitry to collect physiological data from the user, which is then processed by user-targeted circuitry to determine the physiological parameters (e.g., weight and heart-related measurements) of the user. Such parameters are then associated with the user and saved to a data-access circuit, and also forwarded to a display which communicates the physiological parameters among other information to the user through the platform region; the display encompassing substantially all of the platform region, including the region(s) upon which the user would stand for weight measurements.

A scale includes a weigh station for receiving items to be weighed, an operator interface configured to display information associated with scale operations and a controller operably coupled to the operator interface to effect display of information. The operator interface may be in the form of a touch-screen display that is used to facilitate ease of use and scale adjustment.

A method for providing weight accuracy indications for scales, such as vehicle scales, and systems are provided. A controller receives load data from a weighment from one or more sensors of the scale and determines a weight reading. The controller determines an estimated error magnitude for the weighment based on at least one of: at least a portion of the load data and additional data. The weight reading is electronically displayed at a user device along with at least one additional item based on the estimated error magnitude for the weighment.
