A trolley case capable of displaying weight in a static state allows the bracket fixing shaft not to offset in a radial direction through the configurations of a directional bearing and shaft liner, and allows a weighing transducer to sense the weight of a case body accurately by installing the weighing transducer on the directional bearing and fixing the weighing transducer to the upper end face of the bracket fixing shaft, thereby not causing a weight displaying value to change, realizing a static display, and thus giving users the convenience of use.

A device forming a stackable container that can be used to transport products includes a portion forming a crate defining a base and four side walls and a top wall, secured to one another in a sealed manner, made mainly of a plastic material; a door for sealingly closing the crate, forming with the crate, when closed onto same, a sealed box; a system for drawing and compressing gases contained in the closed box; and at least one tight casing for storing the drawn and compressed gases, rigidly connect to the box and forming a bracing frame during transport and a flotation buoy when the container is immersed in water.

Luggage as well as systems, devices, methodologies, and software for use with such luggage are disclosed. The luggage may include one or more compartments and lids that can be locked. The luggage may also include an identification device for obtaining information identifying a user and a computing device, such as a microcontroller or processor. The computing device may be configured to compare identification information with reference identification information to determine whether a user is authorized to access an interior of the luggage. Based on results of the comparison, the computing device may control a locking mechanism to unlock one or more of lids of the luggage to allow a user access to the interior of the luggage. The luggage may also include a GPS transceiver for tracking the luggage, a sensor for weighing the luggage, or a coupling mechanism to couple the luggage to another piece of luggage.

Novel tools and techniques are provided for implementing item or luggage loss prevention, which, in some cases, is based on weight measurement. In some embodiments, a device with a processor can be placed under a bag's handle, within an interior compartment of the bag, below or in the feet or wheels of the bag, and/or the like. The device can allow a user to lock in a weight of the bag. If any item is subsequently removed from (and not returned to) the bag, the device will notify the user, using one or more of audio notification, visual notification, and/or mobile device notification (e.g., via e-mail, text message, SMS, MMS, chat message, and/or the like) that the weight of the bag has changed. In some cases, location detection devices may be implemented to allow the user to backtrack where the missing item might have been left behind.

A smart luggage apparatus includes a case assembly with at least a stowage compartment. A smart handle assembly is mounted to a case assembly. The smart handle assembly includes a controller having a power supply and further powered by one or more battery, where one battery is located in the handle and a second battery is located in the stowage compartment. A smart luggage apparatus also includes a one or more scale that communicates with the smart handle controller and transmits the weight of the case assembly.

A self-weighing luggage device comprises a housing with a towing handle at one end and four wheel units mounted at the other end. Four weight determining sensors are incorporated into the wheel units, respectively. Each weight determining sensor is wired to a central circuit board, which is mounted on the inner surface of other end at position. The central circuit board is connected to a Liquid Crystal Display (LCD) mounted in a recess in the handle end of the housing, which recess is adapted to receive the handle in a stowed position, such that the LCD is protected by the handle. In use, the self-weighing luggage device is stood on the ground on the four wheel units and the weight readings from each weight determining sensor are combined to give the total weight of the self-weighing luggage device, which total weight is displayed on the LCD.
