An embodiment of the present invention relates to a weight measurement system capable of conveniently measuring the weight of an object being measured in real time. Particularly, in the present embodiment, a weight measurement device is formed as a structure arranged between the object being measured and a wheel. The weight measurement device comprises: an upper frame provided at the bottom of the object being measured; a lower frame provided at the top of the wheel; an elastic transformable body of which one end is connected to the upper frame and of which the other end is connected to the lower frame; and a transformation amount sensor provided to the elastic transformable body so as to sense the transformation amount of the elastic transformable body.

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.

A movable container includes: a driving mechanism, a sensing device, and a control circuit. The driving mechanism is arranged to provide a momentum to the movable container. The sensing device is arranged to sense a motion feature in accordance with the momentum provided by the driving mechanism. The control circuit is coupled to the sensing device and the driving mechanism and arranged to calculate a calculated mass of the movable container in accordance with the motion feature sensed by the sensing device. The control circuit is coordinated with the driving mechanism and the sensing device via a user input.

A scale system is provided. The scale system includes multiple scale portions which may be separated to weigh an item that may have multiple feet or wheels, such as luggage. Each scale portion is configured as a pedestal that may wirelessly communicate with a computing device. The computing device receives a signal input from each portion, calculates the total weight based on the signal inputs, and presents this information to a user.

A case holder with weighing sensor that weighs accurately, has a fixing base of a weighing sensor built in the holder, and ensures the fixed end and the loading end of the weighing sensor meet weighing principle. It includes a grip and a lifting arrangement arranged at two ends of the lower surface of the grip and allowed to pass through a case surface to be fixedly connected with a stressed plate below the case surface. A neutral zone of the grip provides a fixing base for arranging a weighing sensor. A fixed end of the weighing sensor is fixedly connected on the fixing base with screw. A loading end of the weighing sensor includes a rigid and structurally closed lifting bushing fixedly connected thereon. The lifting bushing is arranged around the grip, the fixing base, and the weighing sensor and has two ends separately arranged to the corresponding lifting arrangement. The inner wall of the lifting bushing and the grip have a gap therebetween. Contrasting to the prior art, the present invention allows the relationship of the loading end and the fixed end of the weighing sensor to stick to the weighing principle. Therefore, cases that use the holder of the present invention can weight very accurately.

An information processing apparatus includes an information acquisition interface configured to acquire a measurement result from one or more weight sensors configured to measure a weight of a user, and a controller configured to detect an increase in the weight of the user based on the measurement result.

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 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.
