A mobile device case apparatus and method are provided that include a frame, a stand, at least one magnet, and rubber coating over the at least one magnet. The frame and stand can be 3D-printed. The frame is configured to secure a mobile device into the frame. The frame includes at least one magnet. The bottom of the stand can have a rubber coating to prevent the case from slipping when the case adheres to a metal. The stand is configured to support the weight of the apparatus and prop the mobile device up for viewing. The stand can also be configured to be a receive a mechanical element of a vehicle such as a wheelchair.

A trolley is disclosed which includes a frame body, a handle and a player, the player and the handle being linked to one another and rotatable with respect to the frame body. Due to the linkage of the player and the handle, the player may rotate as the passengers rotate the handle, which makes the operation convenient and flexible. The player is driven to rotate through the rotation of the handle to adjust an angle of the player, allowing passengers to watch the player conveniently in various situations like standing, sitting, pushing the trolley, etc., which meets different needs of passengers well and also avoids the blocking of the handle to the player.

Disclosed herein relates to a self-checkout anti-theft vehicle system, comprising: a self-checkout vehicle having a plurality of sensors and components implemented thereon, the self-checkout vehicle being used by shoppers for storing selected merchandises in a retail environment; and a centralized computing device. The centralized computing device is configured to: obtain information related to each merchandise selected and placed into the self-checkout vehicle by a shopper by exchanging data with the plurality of sensors and components via a first communication network, identify each merchandise via a second, different communication network based at least upon the information obtained from the plurality of sensors and components, and process payment information of each merchandise.

An interactive shopping system, or smart cart. The system allows a user to select items in a store and complete a purchase without having to wait in lines or interact with store personnel. The system can have a container for holding products selected by at least one user, a user interface, a scanner in communication with the user interface, a processor in communication with the user interface, and a data storage comprising computer instructions executable by the processor. A user can select products, place them within the container, scan the products, and initiate a payment transaction to complete a purchase.

Systems and methods for automatically taring mobile produce scales include receiving sensor data indicating a weight change event associated with a weight sensor, and generating a tare request. In response to the tare request, a difference in weight data associated with the weight sensor before and after the weight change event may be determined. Stability data associated with the weight sensor may also be used to determine whether to automatically tare the weight sensor. If the difference between the weight data is within a threshold associated with the weight change event, the weight sensor may be automatically tared. If the difference between the weight data exceeds the threshold associated with the weight change event, the weight sensor will not be automatically tared. The weight sensor may then be re-tared manually.

A shopping cart basket comprises one or more modular baskets couplable to a bottom basket having a plurality of wheels extending downwardly to allow the shopping cart basket to roll. Each of the modular baskets has a foldable bottom wall that can act as a bottom of a separate basket or can be folded against a side wall of the modular basket. The modular baskets could be used to hold items within a smaller compartment, and can be combined with the bottom basket to form a roll-able shopping cart having a larger compartment. Such a cart is advantageously used in a store, such as a grocery store, a retail shopping mall, or a home improvement store.

A shopping cart system includes a shopping cart that includes an input connector that receives a charging current and a DC voltage of a DC power supply different from a supply power supply of the charging current, a first resistor connected in parallel to an input line of the DC voltage, and a first output connector that outputs, to an input connector of another cart connected to a subsequent stage of the cart, the DC voltage across the first resistor and a part of the charging current received by the input connector. The power supply device includes a second output connector that outputs a charging current and a DC voltage via a second resistor connected in series to an output line of the DC power supply, and an energization control unit that stops the charging current when a voltage across the second resistor exceeds a predetermined value.
