  • Patent number: 7302278
    Abstract: Methods and apparatus for high throughput wireless cells, capable of functioning as access points, are described. The wireless cells may be equipped with multiple radios to increase the amount of throughput available through a single wireless cell. Multiple antennas attached to the radios through RF switches may enable the wireless cell to service multiple clients simultaneously. The physical sectors of the antennas may overlapped to form virtual sectors that provide greater flexibility in client load management and in simultaneously servicing multiple clients. Attenuators may reduce interference from foreign wireless cells or clients. Systems and methods for assigning minimally interfering channels to either physical sectors or to radios to reduce interference between adjacent sectors and overlapping sectors are also disclosed. An antenna horn may also allow any antenna to be used as a directional antenna and may enable the antenna's angle of coverage to be adjusted.

  • Patent number: 7178515
    Abstract: A coupler enables a paintball hopper to be easily connected to and disconnected from a paintball marker. A part of the coupler is connected to the paintball marker while another part is connected to the paintball hopper. The coupler has a locked and an unlocked position. In the unlocked position, the portion of the coupler connected to the paintball hopper is easily removed from or inserted into the coupler. In the locked position, the paintball hopper is held immobile and capable of being used in a competitive environment. The coupler provides fixed positions while locked and uses techniques to keep the hopper immobile when locked to the paintball marker.
