摘要:
A dual cell rear corner pillar for the operator's compartment of a pick-up truck is formed with longitudinally oriented front and rear tubular members. The dual cell tubular construction increases section strength for the rear corner pillar while maintaining packaging constraints for the rear pillar design. The front tubular member is nested against the rear tubular member to provide support therefor longitudinally and vertically. The forward tubular member is welded to the door opening panel seal flange, while the rearward tubular member is welded to the window flange and the back panel flange. The forward and rearward tubular members are also welded to one another to form a strong pillar structure. The dual cell configuration resists buckling and shares loading. The rear tubular member wraps around the front tubular member and transitions into the roof rail area, shortening the unsupported moment arm of the rear tubular member.

A roll-forming process for the manufacture of a structural member can be used in the manufacture of an automotive vehicle. The roll-forming process creates a component that has multiple cells with an integral internal web separating the cells, enhancing the strength, rigidity and stiffness of the component for any given size and shape. The roll-forming process starts with a piece of sheet metal and rolls the sheet metal into a desired shape and then rolls the tube back over on itself to create a second cell with the internal reinforcing web positioned between two structural cells of the beam. The rolled form is then welded into the formed shape to create the structural beam. The two cells of the beam can be the same general size or be formed as completely disparate sizes, depending on the design requirements of the structural member.

A hydroforming process forms a hydroformed automotive component as a multiple cell member having an integral internal rib separating the cells and reinforcing the hydroformed component to increase the strength of a hydroformed component with a given size and shape. The tubular blank can be manufactured through a roll-forming process or by welding two structural tubular members, to form a tubular blank that has multiple cells with an internal rib separating the cells. The hydroforming process injects fluid under pressure into each of the cells to expand the tubular blank into the shape defined by the die holding the blank. The internal web separating the cells of the blank becomes an integral internal reinforcement spanning the component to enhance the strength, rigidity and stiffness of the component. Providing differential pressure on the multiple cells can stretch and twist the internal rib for positioning internally as desired.

The squirrel repelling bird feeder comprises a first pole section, a second pole section, a cable, a baffle, and a bird feeder. The squirrel repelling bird feeder may be adapted to feed birds from the bird feeder. The bird feeder may be suspended above the ground via the first pole section and the second pole section. The baffle may prevent squirrels from accessing bird seed in the bird feeder. The bird feeder may be lowered via the cable for refilling. The feeder may be retained in an elevated position by securing an end of the cable to an anchor located on the second pole.

A high definition video transmitter and receiver are disclosed. The transmitter provides high definition video to a one-point receiver or to multipoint receivers. The transmission network is asynchronous and the receiver re-synchronizes the video. The transmission can be wired or wireless.

A wireless communication infrastructure entity assigns a plurality of schedulable wireless communication entities to a group wherein each entity is assigned a location within the group. The infrastructure entity indicates which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a radio resource, for example in a first bitmap (510), and indicates radio resource allocation policy information (520) and indicates a weighting for each assigned wireless communication entity, for example, in a second bitmap (530), to the schedulable wireless communication entities that have been assigned a radio resource.

In order to address the above-mentioned need, a method and apparatus for assigning time-domain resources to a wireless receiver is provided herein. During operation a resource assigned to a particular node will comprise a particular-length subframe having a unique combination of a number of contiguous slots and a slot start time. The subframe will repeat after a predetermined number of slots to form a subframe pattern. For a given frequency resource (group of subchannels), each node to which the base station is transmitting a packet will have a unique subframe length, starting slot, and repetition time period. Because each node will be assigned a subframe pattern having a particular length, and because each node's transmissions will begin at varying slots, the resources may be assigned to multiple nodes without having any transmissions overlap.
