  • Publication number: 20130285414
    Abstract: A hinge pillar assembly employed for attaching a front door to an automotive vehicle is disclosed. The hinge pillar assembly includes a first pillar and a second pillar. The first pillar has cavities, which are capable of receiving bulkheads. The bulkheads are adapted based on dimensions of the cavities in order to substantially secure the bulkheads in the cavities. The second pillar is mounted over the first pillar to enclose the bulkheads.

  • Patent number: 8439431
    Abstract: An attachment bracket in a vehicle for providing integrated support for one or more security features required by law enforcement agencies. The attachment bracket includes a first part including a horizontal cross member extending across the top of a rear panel of the vehicle body. The structure further includes a second part, connected to the first part, which includes two or more intersecting cross members. The second part is mechanically coupled to the vehicle body inside the vehicle cabin below the second row passenger seat. The structure also includes a third part, connected to the second part, which includes one or more arcuate tubular members extending along the vehicle floor panel from the second part towards the first row of seats. The third part is open at the end towards the first row passenger seats.

  • Patent number: 7352597
    Abstract: This invention disclosed is a comprehensive power quality controller for substation in the electric power system and includes a Thyristor Controlled Reactor (TCR), pure tuned passive filter Zf, additional inductor L active power filter (APF), and a coupling transformer. The Thyristor Controlled Reactor (TCR) provides inductive reactive power and controls the active power filter (APF) as the current source, it is connected with the additional inductor La in parallel via the coupling transformer, then connected to the passive filter Zf in serial to consist a hybrid power filter system, which is connected to the power grid via the circuit breaker or thyristor. The comprehensive filter system provides required capacitive reactive power and filters the harmonic produced by the load and TCR system itself. Because the capacity of the active power filter (APF) is very small which is less than 1% of the harmonic source capacity, so it is a solution with low cost but simple and reliable control mode.
