    Abstract: Lithium-based and sodium-based batteries and capacitors using metal foil current collectors, coated with porous layers of particles of active electrode materials for producing an electric current, may adapted to produce heat for enhancing output when the cells are required to periodically operate during low ambient temperatures. A self-heating cell may be placed in heat transfer contact with a working cell that is temporarily in a cold environment. Or one or both of the anode current collector and cathode current collectors of a heating cell may be formed with shaped extended portions, uncoated with electrode materials, through which cell current may be passed for resistance heating of the extended current collector areas. These extended current collector areas may be used to heat the working area of the cell in which they are incorporated, or to contact and heat an adjacent working cell.

  • Patent number: 11408744
    Abstract: A method, autonomous system controller, and computer program product generate a first route for an autonomous vehicle to transport a first person from a first location to a destination. In response to determining that a second person satisfies trigger criteria comprising: (i) being at a second location that is within a proximity threshold to the first route; (ii) being associated with the first person; and (iii) being associated with the destination, an affordance is caused to be presented via respective user interface devices to at least one of the first and second persons that proposes that the autonomous vehicle transport both the first and second persons to the destination. In response to receiving acceptance, a second route is generated for the autonomous vehicle that comprises picking up the first person at the first location, picking up the second person at the second location, and transporting both persons to the destination.
