摘要： A radome and a reflector antenna configured to mate with the radome. The radome has a central portion and a surrounding outer portion. The central portion having a radius selected to redirect a reflected component of the transmitted RF signal from the radome to the vertex area of the reflector. The outer portion has a larger radius selected to minimize radiation pattern degradation. RF absorbing material located at the vertex area reduces return loss of the reflector antenna. The radome attaches to the reflector via a plurality of tabs formed proximate the periphery of the radome that correspond to a plurality of cut outs in the periphery of the reflector. When inserted and rotated, the radome secures to the reflector without requiring tools.

摘要： An antenna feed angular alignment tool for an antenna feed and method of use. The tool having a body with a bore between a first end and a second end; a capsule, retained within the bore, having a first material and a second material enclosed within a cavity of the capsule. Coupling feature(s) integral with the body, proximate the first end are configured to rotationally couple with the antenna feed. The first material and the second material having different densities are movable within the capsule, indicating when the capsule and thereby the tool are aligned with a horizontal plane.

摘要： A measurement sensor where a mixed solution enters a manifold (1) and is separated in an entry chamber (2) by a whirlpool and/or setting effect. An accumulation chamber (3) and outflow (4) positioned in the lower peripheral of the entry chamber (2) causes the separated solution to preferentially flow to a sensing tube (6) with surface to sectional area dimensions optimised for high frequency electric field measurement of solution parameters used to determine capacitance and conductivity. Overflow of mixed solution enters (5) similar sensing tubes (7), for mixed flow measurements used to determine mass and flow rate. The number and size of the overflow tubes (7) give minimal head loss through the manifold. Solution is recombined in an exit chamber (10) that causes fluid dynamic restrictions (8) to extend solution residence time in measurement tube (6) before exiting the manifold (11). Also disclosed is measurement of a fluid parameter by improving the measurement sensitivity by at least partially canceling the effect of dielectric properties of the containment wall through which the parameter is sensed, and a method for determining plant performance using stored performance profiles.

摘要： Methods and systems for fast and reliable network recovery from multiple link failures. In accordance with one example of the method, a master node receives a request from a transit node having a blocked port to open the blocked port for data forwarding, wherein the blocked port is associated with a restored link. The master node starts a health-check timer and transmits a health-check message on its primary port to determine that all failed links of the network are restored. Upon determining that the health-check message is received at its secondary port, the master node transmits a message to each transit node indicating that all failed links are restored. Upon determining that the health-check message is not received at its secondary port before the health-check timer lapsed, the master node transmits a message to the transit node to open the blocked port associated with the restored link for data forwarding.
