The invention relates to a push handle unit having at least one transverse strut and having two end pieces which in the assembled state are arranged at the ends of the transverse strut and have a device for fastening to a manually movable transport trolley, wherein the push handle unit has a free-standing, projecting gripping unit on each of the two end pieces. The gripping unit consists in each case at least of a gripping unit receptacle and of a gripping unit insert, and a gripping unit is formed on each end piece. The invention further relates to a manually movable transport trolley having such a push handle unit.

A power generation system for wheeled objects comprises a generator mechanically coupled to one or more of the object's wheels to convert wheel rotational energy into electrical energy. The power generation system may comprise an electrical storage device configured to store the electrical power produced by the generator. Power from the generator and/or the electrical storage device can be used to provide power to other electrical systems in or on the object. In certain embodiments, the electrical storage device comprises a bank of high-capacity capacitors connected in series. Some embodiments use a control circuit, for example, to regulate the charging and discharging of the capacitor bank and to provide suitable voltages for other systems. The power generation system may be disposed within an object's wheel, such as a wheel of a shopping cart.

Methods, systems, and machine readable medium are provided for autonomous item identification in an environment including a mobile computational device and a container. One or more sensors are disposed at the container to sense a selected item being placed in the container. In response to sensing the selected item being placed in the container, a location of the container is determined using a positioning system. One or more physical characteristics of the selected item is sensed via the one or more sensors at the container. A set of stored characteristics is retrieved from a database for available items proximate to the location of the container. An identification code for the selected item is identified based on a comparison of the one or more physical characteristics of the selected item with the stored characteristics retrieved from the database of the available items based on the location of the container.

A shopping cart and method of autonomous shopping are provided including a cart chassis, a scale configured to rest on base of the chassis, a basket resting on the scale, wherein weights of products placed in the basket are indicated by the output signal of the scale, a weight guard rail positioned above the product basket and attached to the cart chassis, wherein a downward force on the weight guard rail does not impose a downward force on the basket and is not indicated by the output signal provided by the scale, a user identification unit; and a payment module.

Disclosed is a trolley baseplate including a plate body having a head end and a tail end, a first locking mechanism on the plate body adjacent to the head end and a second locking mechanism on the plate body adjacent to the tail end. The second locking mechanism is placed corresponding to the first locking mechanism and the structures of the two locking mechanism are fitting. When front and back trolleys are concatenated, the tail end of the front trolley and the head end of the back trolley can be locked to each other by means of the first locking mechanism and the second locking mechanism. The trolleys with the above structures can be concatenated more conveniently, and are not liable to overturn upon sudden braking or turning, which can effectively shorten the time for the staff to fasten two trolleys together.

A method and system of dynamically displaying information to a user is disclosed. A user's location is sensed. Customized information is displayed to the user at a location that is in proximity to the user. The customized information moves as the as the user changes location.

A system for monitoring shopping carts or other human-propelled carts includes wireless access points that communicate on a wireless network with wheel assemblies of the carts. The system is capable of monitoring a path followed by a cart in a store or building, and using the path (optionally together with other criteria) to determine whether to authorize the cart to exit. For example, if a shopping cart fails to pass through a checkout lane of a store, the system may perform an action that blocks or inhibits the shipping cart from exiting the store. The wheel assemblies may include LEDs or other visual indicators that alert store personnel when a wheel assembly is in a particular state.

Described in detail herein are systems and methods for interacting with an interactive display using a shopping cart. A biometric device integrated with the handle portion on a shopping cart can detect and discriminate between user attributes. At least one RFID tags can store the captured biometric information associated with the user attributes. A RFID reader and a computing system can be disposed within a predetermined distance of the shopping cart. The RFID reader can communicate with the at least one RFID tag in response to the at least one RFID tag being with a range of the at least one RFID reader to transfer the biometric information stored in the RFID tag to the RFID reader. The RFID reader can transmit the biometric information to the computing system. The computing system can authenticate the user based on the biometric information received via the at least one RFID reader.

A shopping cart that generates power, and comprising a shopping cart body; a set of wheels that each rotates about an axle coupled to the shopping cart body; a power generator that generates a source of power from a rotational force of the wheels when a user moves the shopping cart; a voltage regulator that controls the source of power output from the power generator; and an outlet for outputting the controlled power to an electronic device.
