Abstract: An apparatus comprising a counterweight, and a controller. The counterweight may comprise a frame, wheel hub motors, friction devices, weight load. The counterweight may be off its equilibrium position. The wheel hub motors may push on the guiderails/beams applying a force. The guiderails/beams front surface may tightly fit between the wheel hub motors and the friction devices wheels to (a) ensure the wheel hub motors rotate without slip. The controller may be configured to receive a signal to power the wheel hub motors and disengages the brake to (i) drive the car upwards, (ii) to drive the car downwards in response to a signal. The controller may be configured to receive a signal to stop the current flow to the motors and engages the brake to stop the car in response to a signal.

Abstract: An apparatus comprising a chassis, a compartment and a safety system. The chassis may comprise a chassis base, curved rear chassis pillars and inclined front chassis pillars. The compartment may comprise a compartment base and curved rear compartment pillars. The safety system may be configured to (a) receive a signal and (b) activate a safety measure in response to the signal. The chassis supports the compartment. The compartment provides seating for occupants of a vehicle. The signal indicates an amount of force. The safety measure comprises (a) lifting a front of the compartment from the chassis, (b) rotating the curved rear compartment pillars along the curved rear chassis pillars and (c) absorbing the force with the chassis base while the compartment is lifted.
