Abstract: A computer-implemented method for dynamic bus routing includes receiving a request from a commuter for transportation from an origin to a destination, determining a commuter bus route to service the commuter request, determining a transportation network company (TNC) schedule from the origin to a commuter bus pick-up point for the commuter, scheduling a commuter bus trip from the commuter bus pick-up point to a commuter bus drop-off point for the commuter, determining a TNC schedule from the commuter bus drop-off point to the destination for the commuter, dispatching a first TNC driver to the origin for the commuter and scheduling a dispatch of a second TNC driver to the commuter bus drop-off point for the commuter.

Abstract: Systems and methods for enabling fast charging of an electric vehicle at a charging station. An electric vehicle in positioned in a given location for charging and/or discharging. A charging arm comprising a plurality of charging brushes is then positioned relative to the position of the electric vehicle. The plurality of charging brushes on the charging arm is positioned to contact a charging interface of the electric vehicle. The charging brushes are moved relative to the charging interface such that a portion of the charging brushes is removed as a result of the movement.

Abstract: The power train of an electric vehicle includes an electric motor and a gearbox coupling the electric motor to a drive wheel. A controller may be configured to initiate a gear shift in the gearbox, and activate one or both of (a) a torque jog in electric motor, or (b) a burst of a pressurized fluid in an actuator to assist with the gear shift.
