    Abstract: The present invention provides a high-performance and small sized helical antenna element and array thereof for use in an aircraft communication system or the like, where stringent spatial restrictions and gain requirements generally apply. The performance of the array is enhanced by increasing the lateral distances between the antenna elements over a portion of the elements where the windings thereof have high current amplitude. The sweeping envelope of the array is maintained small by recovering the initial distancing over a portion of the elements where the windings thereof have low current amplitude.

At least one sleeve member (3; 23; 33; 43; 173) is positioned on the exterior of the casing or liner and is sealed thereto and at least two deformable band members (201; 401, 403; 501) are provided around and are bonded to the outer circumference of the sleeve member. The sleeve member and the at least two deformable band members is/are expanded into place against the inner circumference of the open borehole by increasing the pressure within the sleeve member. The method detailed herein also provides zonal isolation by use of a pair of spaced apart sleeve members during a frac operation where frac fluid is supplied to a zone (in between the pair of sleeve members) requiring to be frac'd, where the frac pressure acts not only on the outside of the zonal isolation device but also on the interior of the sleeve member to enhance the seal provided thereby.

    Abstract: A co-existence method is described. The method comprises setting a priority level of a slot based on the likelihood that the slot will be required by a first radio and signalling the priority level to radio which is co-located with the first radio and which shares a resource with the first radio. The slot may, for example, be a re-transmission slot following a primary transmission slot or may be a sniff anchor point. The likelihood may be determined based on one or more factors, such as historical data or knowledge of the activity of a peer of the first radio.

    SYSTEM AND METHOD FOR PRINTING A CONTINUOUS WEB EMPLOYING A PLURALITY OF INTERLEAVED INK-JET PENS FED BY A BULK INK SOURCE

    Abstract: This invention provides a system and method for printing continuous web and feeding ink to printing pens (or cartridges) that employs an array of interleaved ink-jet pens that are arranged to receive bulk ink through a manifold. The manifold and pens are mounted on a fixed array suspended over the web feed path. The manifold includes a plurality of self-sealing quick-disconnect couplings that each serve a discrete ink-jet pen. The pens lay down ink in a registered manner across the full width of the web. The pens are organized into two parallel, multi-pen arrays that are each diagonally oriented with respect to the feed direction. The feed path allows for duplex printing with a second web-side's array located on a lower level of the device, generally beneath the first-side's array. Duplex printing is facilitated due to its inherent length of the feed path. The printed part of the web is free of contact over predetermined lengths that ensure sufficient time for the drying of ink. Each pen is interconnected with a connection to a respective manifold that maintains a vacuum so as to prevent seepage of ink from the pen nozzles. The vacuum is maintained by a draw pump, while ink is continuously provided to the manifold via a float switch in a pressure regulator. The regulator is fed by a bulk ink supply using a feed pump. A check- valve standpipe on each manifold assists in removing any trapped air from the system, thus assisting in maintaining the vacuum.
