Abstract: An example of an apparatus is provided. The apparatus includes a mount to secure in a vehicle. The mount includes a first lip to insert into a first gap and a first surface to brace against a first wall. The apparatus further includes an additional mount to secure in the vehicle. The additional mount includes a second lip to insert into a second gap and a second surface to brace against a second wall. The second gap is opposite the first gap and the second wall is opposite the first wall. Furthermore, the apparatus includes a support member supported by the mounts at each end. In addition, the apparatus includes a barrier structure supported by the support member wherein the barrier structure is to separate a first occupant of the vehicle from a second occupant of the vehicle.

Abstract: A method for powering down a autonomous power unit includes a spark ignition engine power source having an associated power source actuating system and a power output, comprises a regulator associated with the power source. The regulator comprises a deactivator actuatingly linked to the power source actuating system and having a base and secondary configurations wherein the base configuration allows the rated power output by the power source and the secondary configurations allow a progressively reduced secondary rate of power output by the power source and wherein the secondary rates are less than the base rate. The apparatus further comprises a controller remote from the regulator, for transmitting a control signal to the regulator. The deactivator is actuable in response to the control signal to activate either the base rate configuration or one of the secondary configurations to control thereby regulating the power source.
