Abstract: The present disclosure describes devices and systems that can be integrated with a foldable, manual wheelchair to convert the wheelchair into a hybrid chair capable of both manual operation and motor-powered operation. A wheelchair powering device includes a motor that is operatively coupled to a roller member so that rotation of the motor shaft causes rotation of the roller member. The roller member may be engaged against a tire of the wheelchair so that rotation of the roller member causes rotation of the tire via friction between the roller member and tire.

Abstract: A logistics node receives a purchase order from a customer. The logistics node selects an appropriate carrier to transport products specified in the purchase order and conveys shipping instructions to the selected carrier. The logistics node also coordinates the shipment by interacting with a source node (associated with a supplier of the products) and a destination node (associated with the recipient of the products). According to one exemplary feature, the logistics node provides an interface that permits users involved in the distribution chain to track the status of the shipments without having to enter tracking codes that are unique to individual carriers. According to another exemplary feature, the interface allows a user to access multiple “levels” of information regarding a shipment, including information pertaining to an individual product within a shipment containing multiple products.
