20080267629 | OPTICAL RING NETWORK ARCHITECTURE - An optical ring network architecture including a number (N) of multi-add/drop filters, such as filters formed using symmetrical pairs of frequency routers. Each multi-add/drop filter is coupled to two other multi-add/drop filters using N−2 transmission media, such as optical fibers, to form a ring. The network also includes a number (N) of terminal stations associated with the multi-add/drop filters. A terminal station (p) is coupled with, and receives information from, its associated multi-add/drop filter (p) through a single optical fiber. In addition, the terminal station p is coupled with, and transmits information in a first direction around the ring to, a multi-add/drop filter p+1 through a single optical fiber. Communications from terminal station p to each other terminal station in the first direction are assigned one of N−1 wavelengths such that no two wavelengths on a given optical fiber are associated with communications between terminal stations in the same direction. Moreover, all wavelengths on a given optical fiber may be associated with a communication between terminal stations in either the first or second direction. As a result, each terminal station can communicate with each other terminal station simultaneously using wavelength division multiplexing and N−1 wavelengths. The network may also be bi-directional such that each terminal station p is coupled with, and transmits information in a second direction opposite the first direction to, a multi-add/drop filter p−1 through a single optical fiber. | 10-30-2008 |

20080211275 | SEAT ASSEMBLY FOR A VEHICLE AND A METHOD OF MANUFACTURING THE SAME - A seat assembly for a vehicle includes a support structure and a seat bottom mounted to the support structure. A seatback is coupled to the support structure and is rotatable about a longitudinal axis between a first collision position when applying a first force to the seatback and a second collision position when applying a second force to the seatback. A first energy absorbing member is mounted to the seat bottom for absorbing energy when the seatback rotates to the first collision position. A second energy absorbing member includes a first end coupled to the first energy absorbing member and a second end coupled to the seatback for absorbing energy when the seatback rotates to the second collision position after the first energy absorbing member absorbs energy in the first collision position. | 09-04-2008 |
20080211287 | SEAT ASSEMBLY FOR A VEHICLE - A seat assembly for a vehicle includes a seat bottom and a seatback. The seatback includes a seatback frame and is selectively rotatable relative to the seat bottom from an upright position to a forward position. A seatbelt assembly includes a retractor coupled to the seatback frame and a belt selectively extendable from and retractable to the retractor. A first end of the belt is disposed in the retractor. A guide is coupled to the seatback frame and defines an orifice with the belt slideably extending through the orifice. The retractor and the guide are fixed relative to the seatback frame and the second end of the belt is fixed to the seatback frame. The retractor, the guide, and both ends of the belt rotate from the upright position to the forward position in response to a force exerted on the seatback frame during rapid deceleration of the seat assembly. | 09-04-2008 |
20100176635 | FOLDAWAY CHILD BOOSTER SEAT - A portable, collapsible child booster seat for a vehicle comprises a collapsible seat member that removably rests on a vehicle seat with collapsible arm rests extending upwardly from opposite sides of the seat member. The seat member includes an upper seating surface supported on a collapsible scissors frame seat base. The seat base is raisable to a deployed position and collapsible to a storage position. The arm rests comprise horizontal arms pivotably mounted on raisable legs. The arm rests have a deployed position, wherein the legs extend upwardly from the seat base and the arms extend forwardly, and a collapsed position, wherein the legs and arms are in a generally horizontal position adjacent the sides of the seat base. The arm rests and seat base are operably interconnected, such that raising or lowering the arm rests between their deployed and collapsed positions causes deployment and collapse of the seat base. | 07-15-2010 |
