A system for efficiently and cost effectively monitoring the status of the interface between two dissimilar media is provided. In a preferred embodiment, the system uses principles applied from the theory of time domain reflectometry (TDR), together with novel circuitry and low cost narrow band telemetry, to provide real time monitoring on a continuous basis, as needed. The circuitry involved permits operation of the system without relying on relative values of signal amplitude while employing a novel feedback function that sets the pulse repetition frequency instantaneously to permit an optimum data collection rate as well as a separate measure of the status based on the system operating parameters. It has particular application to real time monitoring and alerting to the effect of scour events in waterways.

A optical scour sensor monitors scour, including deposition and ablation, in bodies of water that may be too lossy to enable use of electrical signals. A specially configured optical fiber is inserted into the sediment and the interface between the sediment and water thereby monitored using a top-mounted control box to pulse light down the cable and capture reflected signals. The optical fiber may be armored by a soft plastic concentric shield and incorporate a micro-bend inducer for detecting minute indentations in the fiber. The presence of a non-liquid, e. g. , sediment, against the cable is detected because the sediment impinges on the fiber causing an indentation therein. At each indentation a reflection is sent back to the source. Using principles of optical time domain reflectometry (OTDR), the location of the indentiation is determined. The data are fed to a remote system for processing, analysis and display.

The present invention pertains to a microwave continuous wave (CW) Doppler adar system for river ice motion detection and real-time kinematic data acquisition using digital signal processing equipment for processing, storing and displaying such data. With less complex electronic signal processing hardware, a Doppler radar ice motion detection and alarming system can be used in conjunction with the system. River ice kinematic measurements are fundamental to analyses of river/ice dynamics. The system herein can be rapidly deployed, requires minimal operator interaction, and can continuously acquire, process, store and display ice kinematic data regardless of visibility conditions. Use of the Doppler radar system is an effective, efficient and precise method and apparatus for obtaining river ice kinematic data.

Arrays of optical fibers connected to specially configured electronics, e. g. , a phototransistor, an LED, an amplifier, a detector, and display, software and PCMCIA A/D board available on a personal computer, are used to obtain continuous real-time acquisition, processing, and visualization of change in a media occurring in natural environments. Alternatively, many of the individual circuit elements above may be replaced with a power meter. In a specific application, data are collected on the depth of sediment below a body of water. As the sediment depth is changed by an event, the ends of the optical fibers in the array display a different reflection or transmission coefficient indicating that water has replaced sediment or vice versa. By knowing which of the optical fiber ends in the array is indicating the changed reflection or transmission coefficient, scour depth or silt accretion may be estimated. A method of employment of the system is also described.

The water/sediment interface in a body of water near bridge piers and simr structures exposed to scour, is sensed and transformed by a frequency-modulated continuous wave method into an audio frequency signal that is related to the water/sediment interface elevation, which is transmitted by radio signal to a remote monitoring station. Radio signals received at the monitoring station are transmitted to a computer, which is programmed to compute the water/sediment interface elevation and to store such computed results for later use. A remote monitoring station may be equipped to monitor several water/sediment interface sensors.

Apparatus for determining the thickness of a configuration having flat, parallel surfaces that are transparent, or nearly so, to pre-specified types of energy. Embodiments comprise a mechanism for illuminating a front surface with an energy source and mechanisms for measuring reflections of the illumination from a parallel back surface. The energy is contained in a spectrum of wavelengths, the energy being refracted in components at unique wavelengths, e. g. , different colored light bands, and similarly reflected from the back surface. The measuring mechanisms, e. g. , spectrometers, determine the relative lateral displacement between two spectral lines in the refracted and reflected beams to enable determination of thickness. Other characteristics of the material of the configuration may be ascertained, e. g. , chemical composition is ascertained by measuring the intensity of responses at multiple wavelengths and comparing this to responses of known materials.

An apparatus for detecting and monitoring scouring around a structural mer uses time-domain reflectometry (TDR) to measure the level of sediment around a submerged portion of the structural member such as a bridge pier, dock, utility crossing, or similar structure. The apparatus includes a time domain reflectometer which transmits a series of electrical pulses, a sensor which is connected with said time-domain reflectometer, and a signal analyzer which receives and interprets the portion of the electrical pulses reflected back to the source from an interface, such as water/air or water/gravel, to calculate the position of the interface along the sensor. Knowledge of the position of the interfaces before and after a scouring event and of the dielectric constant of the surrounding media allows the user to detect and monitor the level of erosion caused by scouring.

A multi-band, variable, high-frequency antenna comprises a pair of transmission lines for conveyance of signals from and to a transceiver, and a pair of braided copper conductor elements, each in electrical communication at a proximal end thereof with one of the transmission lines. Each of the braided copper conductor elements is mounted on a non-conductive support cord, the braided copper conductor elements being expandable and retractable along the support cords on which the conductor elements are mounted. A cord lock is proximate a distal end of each of the conductor elements for releasably locking the distal end of the conductor element at a selected position on the support cord on which the conductor element is mounted. Release of the cord locks permits lengthening and shortening of the braided copper conductor elements, and locking of the cord locks is operative to lock the conductor elements in place on the support cords to selectively fix a length of each of the conductor elements.

A pair of metal plates having a space therebetween are surrounded by a flexible enclosure which is waterproof and which is filled with a dry gas. A pair of electrical conductors connected to the plates extend through and are water-tight sealed to the enclosure. A water-deformable element which expands in the presence of moisture is disposed around the enclosure, and a rigid housing having holes therethrough is disposed around the water-deformable element so that moisture passing through the holes into the water-deformable element causes it to expand to move the enclosure and at least one plate so as to reduce the space between the plates to change the capacitance of the capacitor.

A roof moisture sensing system includes (1) a radio frequency pulse transter, (2) a moisture sensor disposed on a roof, and (3) a radio receiver adapted to monitor resonance of the moisture sensor activated by a pulse transmitted by the pulse transmitter. The receiver is adapted to analyze the resonance of the sensor to determine the presence of moisture in the sensor. The transmitter and the receiver can be remote from the sensor and the roof.
