Abstract: MIMO dual-polarised antenna assembly arranged in a nested arrangement. The antenna assembly comprises a ground plane and a dual-polarised lower band antenna elements mounted to the ground plane proximal to peripheral sides of the ground plane. The location of the lower band antenna elements defines a lower band peripheral boundary. The antenna assembly comprises (1) dual-polarised upper band antenna elements mounted to the ground plane, nested within the lower band peripheral boundary, (2) an upper feeding network configured to connect opposing pairs of lower band radiating elements of the dual polarised lower band antenna elements and feed the lower band antenna elements, the upper feeding network being located within the lower band peripheral boundary, and (3) a lower feeding network positioned below the upper feeding network, and is configured to feed the dual polarised lower band antenna elements via the upper feeding network using a pair of ultra-wideband duplexers.

Abstract: Provided is a cleanable conductivity sensor and related methods having a distal sensing end in which active sensing elements are positioned and an outer fin specially configured to minimize unwanted interference without impacting the ability for automated cleaning of the distal sensing end. A rotatable wiper or brush may be periodically rotated over the distal sensing end, thereby removing unwanted biological build-up and avoiding fouling, thereby increasing the sensor deployment time without active intervention and maintenance.

Abstract: An electrostatic clutch is described comprising a plurality of micron-scale thickness electrodes, adjacent electrodes being separated by a thin film of dielectric material. A power source and controller apply a voltage across two electrodes, causing an electrostatic force to develop. When engaged, a force can be transferred through the clutch. A tensioning device maintains the alignment of the clutch when the electrodes are disengaged, but permits movement in at least one direction. In some embodiments, multiple clutches are connected to an output to provide variable force control and a broad range of torque input and output values. Moreover, the clutch can be used as an energy-recycling actuator that captures mechanical energy from negative work movements, and returns energy during positive work movements.

Abstract: Provided are turbidometers and fluorometers having a unique form-factor to accommodate a number of optical components in a confined geometry. This provides the ability to compensate for change in light intensity from an optical source even in a closed-loop manner. The ability to package reference and signal detectors, along with a relatively large diameter LED light source in a confined geometry is particularly suited for applications requiring small-diameter sensors, such as multi-parameter sonde devices having a total diameter that is in the sub-two inch range.
