A non-contact power supply unit includes connectable units. Each of the connectable units includes a cart wheel guide, a non-contact power supply device configured to perform wireless power charging of a cart, a first connector, and a second connector. The first connector is connectable to the second connector of another connectable unit and the second connector is connectable to the first connector of another connectable unit. The cart wheel guides of the connectable units are aligned with each other when connected.

Some embodiments provide a system comprising: multiple self-propelled motorized transport units; a wireless communication network; and a central computer comprising: a transceiver, a control circuit and a memory storing computer instructions that when executed by the control circuit cause the control circuit to: receive a request from a customer requesting location information for a requested item; identify the requested item is a category of items, and identify category location information; communicate routing instructions to the motorized transport unit based on the category location information causing the motorized transport unit to initiate physical movement; and communicate to the motorized transport unit a species clarification inquiry instruction configured to cause the motorized transport unit, while implementing routing instructions to move toward the category location, to present a clarification inquiry to the customer seeking clarification in narrowing the identified category to one or more products categorized within the identified category.

A navigation system uses a dead reckoning method to estimate an object's present position relative to one or more prior positions. In some embodiments, the dead reckoning method determines a change in position from the object's heading and speed during an elapsed time interval. In embodiments suitable for use with wheeled objects, the dead reckoning method determines the change in position by measuring the heading and the amount of wheel rotation. Some or all of the components of the navigation system may be disposed within a wheel, such as a wheel of a shopping cart.

A stationary wheelchair storage apparatus includes a floor mounted enclosure, an entrance, at least one guard rail, and a wheelchair stopper. The floor mounted enclosure includes a base floor, a first wall, a second wall, and a third wall. The first wall, the second wall, and the third wall are perpendicularly mounted onto the base floor. The third wall is terminally positioned to the first wall and the second wall. The third wall is perpendicularly connected to the first wall and the second wall thus defining a specific storage area for wheelchairs. The entrance is delineated by the first wall and the second wall and provides an opening to enter the floor mounted enclosure. The at least one guard rail internally connected to the floor mounted enclosure to eliminate damages from the wheelchairs. The wheelchair stopper is integrated into the enclosure to secure the wheelchairs within.
