Patent number: 7166023Abstract: A vent assembly has a base and a single piece cover that is attached to the base to form a housing. A partition inside the housing forms an upper compartment that communicates with an outlet at the rear of the cover and a lower compartment that communicates with an inlet through the base. The compartments communicate via an opening through the partition. The partition provides an exhaust passage from the opening to the outlet at the rear of the cover and a barrier to the flow of water from the outlet back to the opening. The partition and cover provide a drain passage from the exhaust passage back to the outlet in case water accumulates near the opening. The vent assembly may be static or include a fan unit to provide a powered vent assembly. Either may be used as the hatch of a combined vent and escape hatch assembly.Type: GrantFiled: June 20, 2003Date of Patent: January 23, 2007Assignee: Transpec, Inc.Inventors: James A.

Patent number: 7005973Abstract: A school bus has a stop sign hinged on an electrical actuator assembly that is attached to the side of the bus. The actuator assembly includes an electric motor that pivots the hinged stop sign from a stored position adjacent the bus to an operative position extending outwardly of the bus in perpendicular fashion and back to the stored position and an electrical control unit that includes Hall effect sensors for controlling the electric motor. These and other components are protected in an outer sealed housing that has a removable cover to facilitate installation and repair. Installation and repair is further enhanced by a removable inner housing sub-assembly that carries the electric motor and the electric control unit and that provides additional protection for these two components. The school bus also has a crossing arm hinged on an identical electrical actuator assembly, that is attached to the front bumper of the bus near the passenger doors.Type: GrantFiled: April 20, 2004Date of Patent: February 28, 2006Assignee: Transpec, Inc.Inventors: James A. Haigh, Richard J. Iminski, Robert C. Rabine, Kevin L. Wolf, Jr.
