A device for adjusting the capacity of a beverage cup is provided. The device includes an insertion unit having at least a volume smaller than an interior volume of a cup and a shape in which a lower end portion of the insertion unit comes in contact with a bottom portion of the cup when inserted into the cup. The insertion unit includes a first magnet sealed in a bottom portion of the insertion unit. The device also includes an outer fixed unit to be placed under the cup. The outer fixed unit includes a second magnet sealed in the upper portion of the outer fixed unit for interacting with the first magnet of the insertion unit and securing the insertion unit to the cup by a magnetic force between the magnets.

A system for refining an item identification model detects a triggering event at a platform, where the triggering event corresponds to a user placing the item on 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.

A scale controller is in communication with a weighing scale for receiving a weight signal, translating the weight signal into a weight for the animal, receiving a wireless identification signal from a transmitter on the animal, translating the wireless identification signal into an animal identification value, associating the weight of the animal with the animal identification value, and transmitting to a data storage unit a data packet containing the weight of the animal and the animal identification value.

A security system for quantitatively verifying a condition of items in a special collections inventory includes a scale in connection with an index of special collection items. Every item in the index has a unique weight within a collection. The scale takes a current weight measurement of a special collections item and automatically reports the current weight measurement to the computing device hosting the index. Using the current weight measurement, the index is searched for a given item by comparing the current weight measurement with a set of indexed reference weights. In response to a match being detected between the current weight measurement and a reference weight among the set of indexed reference weights, a physical condition of the given itemcorresponding with the reference weightis verified as being intact. In response to no match being detected between the current weight measurement and the set of indexed reference weights, an alarm event triggers indicating that the special collections item has been tampered with.

Provided is a cushion capable of accurately measuring and displaying a weight of a user sitting on the cushion, and convenient to store, use, and carry. The cushion includes a flexible sheet constituting a bottom part; a flexible seat having an integrated rectangular space part formed on the flexible sheet; a pressure transfer medium injected into the space part of the flexible seat; a pressure transfer medium injected into the space part of the flexible seat; and a scale for sensing pressure applied to the pressure transfer medium by an external pressure applied to the flexible seat and displaying the pressure as a weight, in which the scale includes a load cell, a base member, a control unit, a first display unit and a second display unit.

Disposition of a wrong liquid for analysis or a liquid for analysis connected to a wrong pipe is detected as abnormal use. A liquid-for-analysis monitor includes: a weighing scale that weighs a container that contains a liquid as a liquid for analysis that needs to be used in analysis; a density storing part that stores a density of the liquid for analysis; and a liquid-for-analysis determining part configured to obtain a variation M between a weight of the container weighed by the weighing scale before a decreasing operation that decreases the liquid for analysis and a weight of the container weighed by the weighing scale after the decreasing operation, and determine whether the liquid for analysis has been normally used in the decreasing operation or not, based on the obtained variation M, a volume V of the decrease in the liquid in the container in the decreasing operation, and the density of the liquid for analysis stored in the density storing part.
