Abstract: A method and apparatus to perform effortless vacuum evacuation for food and wine preserving and meat marinating purpose. The vacuum method allows the apparatus to work with any food sealable vacuum container and wine bottle found on the market. The method also conveniently allows vacuum operation without using tubing to connect between sealable vacuum container and vacuum source. The food and wine vacuuming apparatus are of circular shape, which include vacuum chamber, vacuum source, control circuitry, vacuum switch, and solenoid release valve.

Abstract: A clock network for an integrated circuits includes a first set of lines configured to distribute clock signals to a first section of the integrated circuit. The clock network also includes a second set of lines configured to distribute clock signals to a second section of the integrated circuit separately from the first section of the integrated circuit.

Abstract: A programmable logic device and associated method is provided with repairable regions. In one aspect, general routing interconnect lines are segmented within repairable regions. In another aspect, IO bus lines and associated circuitry are provided that accommodate redundancy in a staggered segmented architecture. In another aspect, a dedicated routing architecture between particular logic regions accommodates shifting to define and utilize repairable regions. Principles of other aspects are illustrated and described in the context of several exemplary embodiments of aspects of the invention.

Abstract: In one aspect, flexible routing resources provided are comprising an arrangement of staggered line segments on a periphery of an electronic device. In another aspect, I/O bus lines a re coupled to receive signals from and to provide signals to other bus lines, core routing, and I/O circuitry, thus facilitating the use of the I/O bus for a variety of routes that may include I/O-to-core, core-to-I/O and core-to-core routes. In another aspect, a length of I/O bus lines is optimized for speed over long signal routes with high fanout. In another aspect, the loading effects of high fanout are minimized by using a plurality of tapping buffers to couple lines to both core routing and to I/O circuitry. In another aspect, a spiraling technique is provided that allows a continuous bus having line segments of consistent length whether or not the number of I/O blocks is an integral multiple of the selected logical length for line segments.
