A high-speed router and method for operation of the core of such a router are disclosed. A switch fabric serves a plurality of ingress and egress ports. Packets are sorted into queues at each ingress port, each queue corresponding to one of the egress ports. Queue status information for each ingress port is communicated to a central scheduler. The scheduler reconfigures the switch fabric to a new port mapping once per epoch, where an epoch is long enough to allow each ingress port to transmit a large plurality of queued packets. The scheduler also sends port mapping information to the ingress ports, so that those ports can match one of their queues with the egress port mapping for each epoch. The switch fabric can achieve extremely high throughput since it doesn't recognize and switch packets per se, but deals with large multi-packet blocks that can be efficiently scheduled by the central scheduler.

A magnetic refrigerator has reciprocated and rotated motions. The body of the apparatus has a nearly tubular shape and contains working pieces at corners, wherein the working pieces surround a shaft with permanent magnet. Compared with existing rotational models, the magnetic refrigerator of the present invention has a relative smaller volume, and the motion of the shaft will be back and forth. Furthermore, a torque eliminating device of the magnetic refrigerator will eliminate the reverse torque when the shaft is driven reverse so that improve cooling efficiency.

This invention provides a vapor-tight luminaire that maintains a moisture-proof, sealed lower housing for the light-producing lamps (fluorescent lights, LED arrays, etc.) while isolating the electronic components in a separate, upper housing that is spaced apart from, and largely thermally isolated from, the lamps. The lamp housing comprises a unitary non-penetrated tubular lens with one or more removable end caps, sealed by gaskets. The lamp assembly is slidably mounted within the lower housing so that it is readily removable and replaceable with another assembly of the same or different type. The electronics in the upper housing is readily accessible and replaceable by removing a top cover that encloses a three sided channel member. The upper housing is metal and desirably enhances heat exchange with the environment. The two housings are held together by a pair of opposing end cap structures that include a housing end and a removable end cap. The housing end includes an upper plate that is fastened against an adjacent end of the upper housing's channel member. This compresses gaskets that stand between the respective ends of the lens and a lower ring on each housing end. The electronics of the upper housing is interconnected via a wiring harness connector to an end connector in on the lamp assembly. The wiring harness passes between the two housings free of penetration of the lens.

A low-loss, high-efficiency, broadband antenna including both electric and magnetic dipole radiators is provided herein. The broadband antenna may be referred to as a “P×M antenna” and may generally include a ground plane; a magnetic radiator formed within the ground plane; a conductive feed arranged within a first plane, which is parallel to the ground plane; and an electric radiator arranged within a second plane, which is perpendicular to the ground plane and coupled at one end to the conductive feed.

The necessary inherent axial tension in the bolt / fastener system is accommodated by a relief element which relieves at least some of the stored tension before the nut separates, thereby reducing the physical shock on the assembly. The energy needed to separate the nut and bolt is entirely contained within the system so that pyrotechnic devices are unnecessary for the purpose.
