Abstract: A multi-beam communication system uses an array of antenna assemblies, and RF elements, to provide two or more sets of multiple beams, where each individual set of beams can be considered a beam state. An antenna assembly has a first set of RF elements oriented to produce a first beam state, and a second set of RF elements oriented to produce a second beam state. Each set of RF elements comprise a set of output sectors, where a controller is configured to selectively activate a beam state.

Abstract: Methods and systems are disclosed to compress raw, liquids-rich natural gas to high pressures while removing heavier hydrocarbons and water through inter-stage gas processing. Some variations provide a method for purifying and compressing natural gas, comprising: conveying a methane-containing input stream to first-compression stages; generating an initial compressed gas stream at a first pressure; conveying the initial compressed gas stream to a low-temperature separation sub-system configured to remove liquid contaminants, thereby generating an intermediate compressed gas stream at a second pressure; conveying the intermediate compressed gas stream to second-compression stages, to generate a compressed gas product stream at a third pressure; recovering purified and compressed natural gas; and feeding the compressed gas product stream into a mobile container. The sub-systems are preferably integrated into a single unit.

Abstract: The inventive subject matter provides apparatus, systems and methods in which a high port count base station antenna uses an array of spherical lenses with multiple ports per frequency band, containing multiple frequency bands, and capable of multiple beam operation. In a preferred embodiment, the antenna system comprises a plurality of spherical, dielectric lenses, stacked vertically, where each lens is surrounded by four or more lower frequency radiating elements, or one circular element. The circular element can have multiple sub-elements, along with feed gaps.

Abstract: A radio frequency antenna array uses lenses and RF elements, to provide ground-based coverage for cellular communication. The antenna array can include two spherical lenses, where each spherical lens has at least two associated RF elements. Each of the RF elements associated with a given lens produces an output beam with an output area. Each lens is positioned with the other lenses in a staggered arrangement. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically phase compensate the output beams produced by the RF elements based on the relative distance between the RF elements.

Abstract: There is provided a sealing assembly for a bearing assembly that supports a rotating tubing string that extends through the riser. The sealing assembly has a plurality of sealing elements. Each sealing element has a seal body having an inner sealing surface designed to seal against a tubular body. The sealing assembly also has one or more sleeves that removably attach between adjacent sealing elements. Adjacent sealing elements are attached to the one or more sleeves in axial alignment. A chamber is formed by the adjacent sealing elements and the corresponding sleeve. The sealing assembly further has a bearing attachment for attaching the plurality of modular sealing elements to a rotating portion of the bearing assembly such that the sealing elements extend downward in series from the bearing assembly and rotate with the rotating tubing string.

Abstract: A variably controlled stagger antenna array architecture is disclosed. The array employs a plurality of driven radiating elements that are spatially arranged having each radiating element or element groups orthogonally movable relative to a main vertical axis. This provides a controlled variation of the antenna array's azimuth radiation pattern without excessive side lobe radiation over full range of settings.

Abstract: Systems and techniques detecting a reverse current are disclosed. An apparatus comprises a switching circuit coupled to a load and a reference node. The switching circuit may be capable of conducting a reverse current from the reference node to the load when a voltage at the load is lower than a voltage at the reference node. A voltage source has a first terminal coupled to the load, a second terminal configured to follow a voltage at the load, and produces a voltage proportional to a voltage drop across the switching circuit. A comparator circuit is coupled to compare a voltage at the second terminal of the voltage source to the voltage at the reference node and configured to indicate when the reverse current has a magnitude greater than a predetermined threshold.
