Abstract: Aspects of the subject disclosure may include, for example, a polarization shifter including a lower substrate having disposed thereon first and second transmission lines for coupling to a feed network, an upper substrate having disposed thereon third and fourth transmission lines for respective communicative coupling to orthogonally-polarized elements of a radiating element, and a dielectric layer residing between the lower substrate and the upper substrate, the upper substrate being configured to mechanically couple to the radiating element, the dielectric layer coupling the first transmission line with the third transmission line and coupling the second transmission line with the fourth transmission line, the upper substrate being rotatable relative to the lower substrate to effect polarization adjusting for the radiating element to facilitate avoidance of interference or passive intermodulation (PIM). Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a motorized drive assembly that includes a motor and a drive assembly, where the drive assembly has an axle configured to be disposed through a rotatable substrate of a polarization shifter for a dual-polarized radiating element, the axle being further configured to fasten, at a first end of the axle, to a support structure of the polarization shifter, wherein, when the motorized drive assembly is assembled to the polarization shifter, the motor is controllable to impart rotational forces, via movement of the axle, to the polarization shifter to effect polarization adjusting for the dual-polarized radiating element. Other embodiments are disclosed.

Abstract: A method and system for providing cargo or product to an individual. The system may be a vehicle and include a plurality of bays, at least one of the plural bays having two rectangular frames, each frame having two horizontal members and two vertical members and each frame opposing and facing the other. The vehicle may also include a holding structure engaged by both of the rectangular frames, the structure comprising a plurality of trays wherein the structure is adaptable to provide vertical movement of the plural trays within the confines of the two rectangular frames. The vehicle may also include one or more mechanisms positioned between the lower horizontal members of the two rectangular frames, the one or more mechanisms adaptable to provide lateral movement within the confines of the two rectangular frames.

Abstract: A method of easily-accessible, versioned, secure, redundant backup of digital information involves establishing a back-end data store connected to a world-wide telecommunications network. Users communicate with the data store using a variety of user a computing devices, each of which has installed thereon client software capable various operations, including communicating with the data store, monitoring a second data store, detecting and replicating changes in the second data store, and selecting data to be transmitted over the telecommunications network to and from the back-end data store. Users may establish policies for data backup and transmission, may monitor the status of data backup, may browsing the back-end data store, may review prior versions of data stored on the back-end data store. The data store is configured for remote management by a user, including deletion of data in the second data store if the computing device is lost or stolen.

Abstract: A polyamide having a viscosity of between about 20 and about 40 FAV and a number average molecular weight of between about 9,000 and about 16,000 grams per mole is provided. The polyamide also includes un-terminated endgroups, where a difference between a concentration of carboxylic acid endgroups and a concentration of amine endgroups is about 5 meq/kg or less.

Abstract: A method for operating a rotary machine is provided. The rotary machine includes a stationary member and a rotatable member wherein the rotatable member is configured to rotate at least partially within the stationary member. The method includes determining an off-normal operating condition of the rotary machine facilitating undesirable contact between the rotatable member and the stationary member, monitoring a parameter associated with the off-normal operating condition, and preventing operation of the rotary machine while the monitored parameter is within a predetermined range.

Abstract: A method and apparatus for reducing self sealing flow in a combined cycle double flow steam turbine, the method and apparatus include providing a brush seal in a packing ring of a packing ring assembly at either end defining the double flow steam turbine.
