Abstract: A system and related method for separating floating and nonfloating particulate and entrained, suspended, and/or dissolved contaminants from a fluid. The system includes a tank with a lower chamber spaced from an outlet or upper chamber by a confinement deck. The deck includes one or more sockets for receiving one or more filter units for fluid treatment. In addition, the lower chamber of the tank acts as a pretreatment sump to remove floating and nonfloating particulates, thereby reducing the load on the filter units. The filter units are configured for radial and/or upward flow of the fluid from the lower chamber. The filter units may include one or more filter media through which the fluid pass prior to exiting the tank. The filter units include a removable screening retainer for retaining the filter media and/or to screen relatively large contaminants. The filter unit may be removed for ease of tank maintenance and replacement of filter media.

Abstract: A rotary cable connector assembly for connecting coaxial waveguides. The assembly includes a metal stator having a counterbored well and a metal rotor extending coaxially into the well. An axial air gap is formed between the stator and rotor which each contain a conventional dielectric sleeve and center element for mating conventionally to carry a signal therebetween. An electrical connector/dynamic RF shield for providing an electrical path across the rotary joint and for shielding the air gap includes a pair of rings having crenelated cylindrical leaves extending axially toward each other and being interspersed. Each ring has a face for making electrical contact with the stator and rotor. A spring urges the rings into contact with the stator and rotor. The crenelated leaves provide RF shielding of the air gap surrounded by the shield. The rings are formed of bronze or other non-precious metal or alloy.

Abstract: A communication hub for controlling an external infusion device includes a first communication interface for transferring information from at least one external device to the communication hub, and a second communication interface for transferring the information received from the at least one external device from the communication hub to the external infusion device. The communication hub is configured to be connected to the external infusion device.

Abstract: A rotary microwave antenna system suitable for satellite or cellular microwave radio telecommunications features an integrated, low-profile, rotary microwave joint, slip ring and antenna assembly. The rotary antenna system includes a stator (i.e., stationary portion), for attachment to a mobile platform (e.g., an automobile or other vehicle), having a rotary joint coaxial microwave coupler for electrically coupling a microwave transmission line from a microwave telecommunications radio system to a microwave antenna element of an microwave antenna rotatable about an axis relative to the mobile platform. The rotary antenna system also includes a rotor (i.e., rotary portion) for attachment to the microwave antenna. The rotor includes a slip ring circuit (or brushes) for coupling power and low frequency electrical signals to the microwave antenna through contacting brushes (or slip ring) attached to the stator, rotates relative to the stator, and is concentric with the axis of rotation of the microwave antenna.

Abstract: A method of sensing alternating current in a cable having at least a pair of longitudinal conductors each of the pair carrying a current equal or unequal in absolute value to the other in mutually opposite directions, is comprised of disposing a coil with its lateral plane adjacent the cable in a position whereby electromagnetic fields caused by the currents intersect primarily different portions of the coil and induce current in the coil, and detecting the induced current in the coil.
