Abstract: Certain embodiments provide a breakaway drive system that includes an actuator, an actuator breakaway, a shaft breakaway and a drive shaft. The actuator breakaway is operably connected to the actuator and is configured to rotate when the actuator is displaced. The shaft breakaway includes a breakaway mechanism for disengagingly connecting the actuator breakaway to the shaft breakaway. The shaft breakaway rotates in unison with the actuator breakaway when the shafts are operably engaged and does not rotate in unison with the actuator breakaway when the shafts are disengaged. The drive shaft is operably connected to the shaft breakaway such that rotation of the shaft breakaway causes rotation of the drive shaft. An external force on the drive shaft that exceeds a threshold causes rotation of the shaft breakaway such that the breakaway mechanism disengages the shaft breakaway and the actuator breakaway.

Abstract: Certain embodiments provide a stop-arm with camera system for a vehicle. The stop-arm with camera system includes a shield, a stop-arm, and a camera assembly. The stop-arm includes a first side and a second side. The stop-arm is deployable between a first position where the first side of the stop-arm is disposed at least partially inside the shield, and a second position where the stop-arm is substantially perpendicular to the shield. The camera assembly is coupled to the first side of the stop-arm. In various embodiments, the stop-arm with camera system is mounted on a rear passenger side of the vehicle, which may be a bus. In certain embodiments, the camera assembly provides a view including an area that is under the vehicle and between a rear wheel of the vehicle and a front wheel of the vehicle when the stop-arm is in the second position.

Abstract: Certain embodiments provide breakaway drive systems for use in connection with vehicle signage, and methods of use. The breakaway drive system may include an actuator, an actuator breakaway, a shaft breakaway and a drive shaft. The actuator breakaway may be operably connected to the actuator. The actuator breakaway may be configured to be rotated when the actuator is displaced. The shaft breakaway may include a breakaway mechanism for disengagingly connecting the actuator breakaway to the shaft breakaway. The shaft breakaway may rotate in unison with the actuator breakaway when the shafts are operably engaged. The shaft breakaway may not rotate in unison with the actuator breakaway when the shafts are disengaged. The drive shaft may be operably connected to the shaft breakaway such that rotation of the shaft breakaway causes rotation of the drive shaft.
