Abstract: A computer includes a processor and a memory, and the memory stores instructions executable to determine a currently activatable feature on a vehicle from a plurality of features; establish negotiations between each of a plurality of Ultra-Wideband (UWB) anchors of the vehicle and at least one mobile device; select a search strategy based on the currently activatable feature; upon selecting the search strategy, during a search iteration, determine distance data to at least one mobile device from a subset of UWB anchors, and inhibit a remainder of the UWB anchors other than the subset; perform a trilateral calculation on the distance data for the mobile device; and actuate a component of the vehicle according to the currently activatable feature based on a result of the trilateral calculation.

Abstract: A process for selectively removing carbon dioxide from a gaseous stream by converting the carbon dioxide to a solid, stable form is provided. In a sequestration process, carbon dioxide enriched air is passed through a gas diffusion membrane to transfer the carbon dioxide to a fluid medium. The carbon dioxide rich fluid is then passed through a matrix containing a catalyst specific for carbon dioxide, which accelerates the conversion of the carbon dioxide to carbonic acid. In the final step, a mineral ion is added to the reaction so that a precipitate of carbonate salt is formed. This solid mineral precipitate can be safely stored for extended periods of time, such as by burying the precipitate in the ground or depositing the precipitate into storage sites either on land or into a body of water. An apparatus for removing carbon dioxide from a gaseous stream is also provided.
