Abstract: An aerial vehicle system for mapping an object buried in a subterranean surface, the aerial vehicle system including an aerial vehicle, an electronic sensor, a processor, and a memory. The memory includes instructions, which when executed by the processor, cause the system to receive a first input data set by the electronic sensor, the first input data set based on an electromagnetic signal and geographic location data, generate a raw image based on the first input data set, and compare the raw image to a calibration data set, the calibration data set based on material calibration data. The material calibration data is based on unique spectral reflection patterns of an object in a controlled environment at predefined heights and subterranean conditions.

Abstract: A method for mapping an object buried in a subterranean surface includes receiving a first input data set. The first input data set is based on a GNSS signal, a SAR signal, and a GPR signal. The method further includes generating a raw image based on the first input data set, comparing the raw image to a calibration data set, identifying an object based on the raw image compared to the calibration data set, transmitting object data to a ground-based post-processing unit, and displaying the object data to a graphic user interface. The calibration data set may be based on material calibration data. The object data may be based on the object identified.

Abstract: A convertible device that is transformable from a storage bag to a marine signal flag by providing water permeable open mesh body of hollow material with stitched edges and an access opening. Rods on the interior of the body are attached to diagonally opposed corners. The rods disconnect to provide a bag form. The rods connect to provide a rigid brace between the diagonally opposed corners of the interior of the material to provide a flag form. Eyelets along a stitched edge of the material are used to attach the device to a flag pole.

Abstract: A system for three-dimensionally modeling and restitution a subject, the system comprising a housing suitable for being carried in the hand by an operator, the housing having an optical unit with stereoscopic digital video cameras co-operating with an inertial navigation unit having a trihedron of optical fiber gyros and a trihedron of accelerometers for generating position and displacement signals in a frame of reference. The housing may also include, in particular, a telemeter laser, an infrared video camera, a GPS unit, inclinometers, and tri-flux magnetometers. A second subassembly connected to the housing by an optical and/or electrical connection cable contains an electrical power supply, electronic circuits, and a microcomputer for processing signals delivered by the housing and for generating a three-dimensional model of the subject, implementing a photogrammetric technique.

Abstract: A fish test circuit for the evaluation of waterway barrier bypass systems with a conduit having at least one bypass system test station, water flow within the conduit, fish introduced into the conduit, and measurement of the effectiveness of the bypass system under test. In the preferred embodiment of this invention, the measurement of the effectiveness of the bypass system under test includes determining the survival or mortality rate of the fish as they pass through each bypass system undergoing test. The test circuit may be a closed loop or a side channel of another waterway. An important benefit and feature of this invention is the capability to evaluate multiple and differing bypass systems under similar water flow, water conditions and water quality conditions.

Abstract: The present invention is a safe and effective fish ladder for assisting fish in overcoming dams, especially in the upstream direction. The ladder comprises a series of relatively vertical open pools, which decrease in size in the upstream direction, the pools being conveniently spaced apart a vertical distance which may be easily jumped by the particular fish species of interest. By being arranged relatively vertically, so that the downstream perimeter of one pool is substantially within the downstream perimeter of the pool directly beneath the one pool, the fish ladder does not need to be long and expensive if the dam to overcome is high. Also, by being relatively vertical, the ladder may be conveniently built onto already existing vertical components on the downstream side of a dam, for example, onto the support structure for the discharge flume for downstream migrating fish in the apparatus disclosed in U.S. Pat. No. 5,161,913 (Boylan).
