Described herein is a system to provide continuously measurements of an analyte present in a fluid sample, particularly dissolved oxygen in wastewater. The system comprises a sample chamber absent of ambient light to contain the sample and in many embodiments employs a non-invasive method of measuring the analyte and determining the change over time in the concentration of the analyte. It is also an aspect of the invention to deliver analyte measurements in real-time and provides the operator with feedback in substantially less time after sample collection than previously accomplished in the field. It is another aspect of the invention to simultaneously or at least in a substantially short period of time thereafter measure temperature to remove initial error encountered at the start of analyte measurement at least until the sample chamber reaches thermal equilibrium.

Systems and methods for continuous measurement of an analyte

The present invention involves a system for the release of low relief, self-orienting deployable payloads from a platform such as a submersible vehicle and a mechanism of passive buoyancy compensation of the vehicle. The system secures one or more payloads by a vacuum force without an additional mechanical restraining mechanism and deployment of a payload is accomplished by disengaging the vacuum hold to release the payload for its intended function. Once deployed, the payload may reorient itself to a functional orientation without additional assistance.

A self-contained monitor array for measuring at least one type of electromagnetic emission and at least one type of mechanical wave emission from a marine-based and/or terrestrial human activity or installation such as alternate energy sources. A multi-modal monitor system includes at least two such arrays, at least one clock, and at least one data storage unit. The monitor system is employed at the site of a turbine installation to measure at least one type of emission generated by the turbine and may comprise a controller to compare the emission signals with pre-determined acceptable value ranges and adjust the performance of the turbine accordingly.

Sensor system for environmental impact monitoring

A fishing lure that contains electronics and provides the lure with characteristics that better attract fish. The fishing lure has a body with external flank surfaces. A plurality of light sources are contained within the lure. The light sources shine light out from the flank surfaces of the lure when activated. A light sensor in the lure detects ambient light levels outside of the lure. The light levels detected by the light sensor are used to control the output intensity of the light sources as they activate. In addition to internal light sources, the fishing lure may also contain a transducer for creating acoustical particle motion in the water. Both the light sources and the transducer are controlled in a unique manner that causes the lure to closely mimic the visual and acoustical properties of a live baitfish.
