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.

The present invention is directed to a trolley case with a charging device, which comprises a case body, a pull rod frame mounted on the case body and a traveling wheel mechanism installed at the bottom of the case body; the pull rod frame is provided with a telescopic pull rod used for dragging the case body, the pull rod frame is provided with a charger accommodating cavity positioned in the middle of the pull rod and used for placing a charging device, the upper part of the charger accommodating cavity is provided with an opening, sliding chutes are arranged on both sides of the opening, and a sliding cover used to cover or open the opening is slidably arranged in the sliding chutes. The independent storage position of the external charging device of the present invention is convenient for taking the charging device at any time, and the setting of the sliding cover prevents the charging device from falling out easily; the spring can eject the charging device and can make the charger accommodating cavity adapted to charging devices of various specifications, the specifications of the charging device are proportional to the compression deformation of the spring, the larger the charging device is, the more greatly the spring is compressed, and the smaller the charging device is, the more slightly the spring is compressed.

Described herein is a weight or pressure measuring shovel. The shoveling apparatus has a broad blade assembly or scoop assembly including an elongate handle member. A coupler assembly is designed to couple the curved plate assembly to allow angular orientation or movement of the curved plate assembly to be adjusted relative to the handle member. A force transducer converts the weight or pressure of a material on the curved plate assembly into an electrical signal designed to communicate the weight or pressure of a material such as snow, sand, dirt, or ice. A control module in a housing mounted on the elongate handle is designed to receive electrical signals from the force transducer assembly or a load cell assembly. A display assembly is coupled to the electrical scale assembly and control module.

The disclosure includes a scale comprising a housing, an arm hingedly coupled to the housing, and a display located on the housing. In some embodiments, the arm is configured to receive at least a portion of an item to be weighed, and the display is configured to show the weight of the item. The scale may be configured to couple to a wall of a building.

A vehicle can include throttle, braking, and steering systems. The vehicle can further include a computing system that obtains, from one or more sensors, data representing one or more of a velocity or an acceleration of the vehicle. The computing system can further determine an estimated weight of the vehicle based on the one or more of the velocity or the acceleration of the vehicle, and autonomously operate the throttle, braking, and steering systems of the vehicle based on the estimated weight of the vehicle.
