Abstract: Processing circuitry provided in a mobile device of a user requiring mobility assistance is programmed to: request multimodal personal transportation assistance from a pool of candidate companions, receive a location of a selected companion and a proposed route between the user to the selected companion, and determine an estimated time of arrival of the selected companion at a current location of the user. The proposed route includes pedestrian travel and the request for multimodal personal transportation identifies any specific needs of the user.

Abstract: A substrate system for receiving a deposit of sprayed metal droplets including a movable outer substrate on which the sprayed metal droplets are deposited. The substrate system also includes an inner substrate disposed adjacent the outer substrate where the sprayed metal droplets are deposited on the outer substrate. The inner substrate includes zones of differing thermal conductivity to resist substrate layer porosity and to resist formation of large grains and coarse constituent particles in a bulk layer of the metal droplets which have accumulated on the outer substrate. A spray forming apparatus and associated method of spray forming a molten metal to form a metal product using the substrate system of the invention is also provided.
