Abstract: An apparatus for operating a reciprocating arm vehicular safety device with a magnetized element for preventing inadvertent deployment of the reciprocating arm. The apparatus has a magnetized element on the arm and an electromagnet on a vehicle bumper, the magnetized element and electromagnet disposed so as to engage the arm in a retracted position. When the reciprocating arm is moved to an extended position, current is passed through the electromagnet to repel the magnetized element, thereby allowing the arm to move to the extended position by a motor.

Abstract: An apparatus for operating a reciprocating arm vehicular safety device with a lock for preventing inadvertent deployment of the reciprocating arm. The apparatus has a rotor provided with retaining fingers for engaging the reciprocating, rotatable between locked and unlocked positions. When the reciprocating arm is retracted the rotor rotates to the locked position, and drive circuitry deactivates the device in response to stalling of the rotor drive motor.

Abstract: A warning system for a multi-passenger vehicle such as a school bus which prompts the driver to inspect the vehicle for passengers when shutting down the vehicle. In the preferred embodiment the system is activated when the vehicle safety flasher system is activated. Following activation an alarm sounds when the vehicle electrical system is deactivated by shutting off the engine unless the bus driver activates an alarm delay switch and within a preset time interval activates a disarming switch located near the back of the passenger compartment. Thus, in order to deactivate the warning system of the invention the bus driver must walk through the passenger area of the vehicle at least twice, inspecting the passenger area of the vehicle in the process. The time taken to inspect the vehicle serves as a cool-down period for the vehicle engine, which is desirable in the case of turbo charged vehicle engines.
