A system comprises a trolley for travel along an aisle of an aircraft interior. An infrared sensor is mounted on the trolley, a controller is operatively connected to the infrared sensor, and an output device is operatively connected to the controller. The controller includes machine readable instructions configured to cause the controller to receive input from the infrared sensor and to issue an alert to the output device upon detection of an obstacle in the input from the infrared sensor.

Embodiments of the invention are designed to be improvements over existing wheelbarrows. Certain embodiments comprise a frame, one or more weight-bearing wheels, and a pan. In certain embodiments, a wheelbarrow comprises a bight or a bumper having wheels. The wheels on the bight or bumper are located to the sides of a weight-bearing wheel. In certain embodiments, wheels located on each side of a bight or bumper portion allow a user to maneuver a wheelbarrow up or down a curb, or navigate stairs without causing damage to surfaces. Certain embodiments of the invention allow more efficient unloading of the contents of a wheelbarrow bed. Certain embodiments are designed to retrofit on existing wheelbarrows.

A cart has a folded configuration and a deployed configuration. The cart includes two side frames arranged opposite to each other; and a plurality of support members connected between the two side frames. Each side frame includes a vertical synchronization rod with a front foot assembly and a rear foot assembly arranged on two sides of the vertical synchronization rod. The front foot assembly includes a front foot rod with an upper front oscillating rod and a lower front oscillating rod hinged between the vertical synchronization rod and the front foot rod. A bottom of the front foot rod is hinged to a front wheel. The rear foot assembly includes a rear foot rod with an upper rear oscillating rod and a lower rear oscillating rod hinged between the vertical synchronization rod and the rear foot rod. A bottom of the rear foot rod is hinged to a rear wheel.

A stackable handcart includes a cart frame, a display, and a restriction member. The cart frame includes a receiving portion on which a shopping basket is placeable and a front end portion that abuts a first stackable handcart when the stackable handcart is stacked with the first stackable handcart from behind the first stackable handcart. The display is attached to the cart frame. The restriction member is attached to the cart frame at a position to abut a front end portion of a second stackable handcart when the second stackable handcart is stacked with the stackable handcart from behind the stackable handcart. The restriction member is positioned such that a display of the second stackable handcart does not abut the display of the stackable handcart when the front end portion of the second stackable handcart abuts the restriction member.
