Abstract: It is common for the organizers of endurance sports to provide aid stations along the route where participants may receive water to prevent dehydration. To reduce waste at these events, organizers encourage ‘cupless’ races that requiring participants to carry their own vessels. The present invention comprises a hat with a visor, such as a baseball style cap, with a collapsible drinking vessel integrated into the visor. During the course of the race, a runner may encounter a water stop and require a vessel to contain the liquid for immediate consumption. At such time the runner can simply remove their hat and configure the vessel to the open position to receive the liquid. Post-consumption the vessel is configured back to the closed position and becomes seamlessly integrated into the visor with no negative effects upon the runner.

Abstract: Routability (or wiring congestion) in a VLSI chip is becoming increasingly important as chip complexity increases. Congestion has a significant impact on performance, yield, and chip area. The present invention targets the optimization of congestion early in technology independent synthesis prior to physical design. Instead of attempting to optimize the logic structure as well as the spatial placement of a circuit, we pose a more modest goal limiting such optimization to the scope of logic synthesis. That is, we propose an aggressive optimization approach that is cognizant of circuit structure during technology independent synthesis and produces more predictable implementations which give better routability and yield.
