An underground radio communications and personnel tracking system uses a portable communications device worn by a miner when underground in a mine. A cap-lamp transceiver provides voice and text communication on ultra-low frequency (ULF) to ultra-high frequency (UHF) carrier frequencies and modulation adapted by programming of a software defined radio to making selective and agile radio contacts via through-the-earth, conductor/lifeline, coal seam, tunnel, and ionosphere/earth-surface waveguides for transmission of electromagnetic waves. These waveguides comprise layered earth coal and mineral deposits, and manmade mining complex infrastructures which serendipitously form efficient waveguides. Ultra-Low Frequency F1/F1 repeaters are placed underground in the mine, and providing for extended range of communication of the cap-lamp transceiver with radios and tracking devices above ground of the mine.

A combination of SAGD with cogeneration technology for exploiting shallow heavy oil and bitumen reservoirs under primary, secondary and tertiary thermal recovery. Superheated steam is generated by the heat recovery from the exhaust of an above-ground hydrocarbon powered turbine driven electric generator cogeneration plant and is injected through well bores into the hydrocarbon bearing reservoir that is traversed by at least one horizontal producing well bore and one injection well bore to heat the reservoir formation and to induce gravity drainage of the hydrocarbons and allowing their recovery from the horizontal producing well bore. Electrical power that is generated is sold to the electric grid and can be used to offset the fuel costs for the above ground hydrocarbon turbine-driven elector generators.

Receiving units with inputs that may be ground-terminated and with inputs that are selectively ground-terminated or non-ground terminated are enabled with signal level shifting and a termination mode selection input. In a first exemplary implementation, a receiving unit is capable of having ground-terminated inputs. However, common mode voltage of the signal that is input to decoding data recovery circuitry is above ground because the input signal may be level shifted in between the ground-terminated inputs and the decoding data recovery circuitry. In a second exemplary implementation, a mode selection is accomplished by switching a voltage divider into operation and bypassing a level shifter for a non-ground terminated mode. For a ground terminated mode, the voltage divider is switched out of operation and the level shifter is switched into operation for its signal output to be decoded. Pre-amplification may also be employed to improve signal strength.

An apparatus and method for treating and reusing the wastewater discharged from agricultural animal farms. The apparatus and method of the present invention is designed to be a zero discharge system in which no wastewater will be discharged or spray irrigated. The wastewater effluent is first passed through a mechanical screen were bulk solids are separated and partially de-watered. The screened effluent is then directed to a primary plastic-lined earthen lagoon where it undergoes aerobic digestion utilizing specially selected bacteria. After treatment in the primary lagoon, the wastewater effluent is used to wash the floors of the hog houses or undergoes a purification phase including solids separation/denitrification, filtration and sterilization. The solids separation/denitrification phase (clarification) preferably takes place in an anoxic environment in preferably above-ground tanks where suspended solids removal will occur as well as denitrification for nitrate reduction. The clarification process may be facilitated through use of polymer addition. The majority of solids will be sent to a plurality of drying beds for de-watering and subsequent removal.

The security manhole insert cover relates to a locking manhole insert to prevent ingress or egress to a manhole from above or below the manhole to prevent access to underground utilities, tunnels and underneath buildings and metropolitan areas to eliminate security intrusions and terrorist attacks by underground access, which would otherwise go undetected if access to the underground utility passages were not secured.

Defects may include, for example, damage and flaws in load bearing concrete structures wrapped in plastic, fiberglass or composite sheathing, while buried objects amenable to detection include landmines or above-ground mines.

When an underground pipe carrying a fluid, such as a buried water-pipe, develops a leak the leak must first be located before it can be repaired. One common location method makes use of the fact that the leaking fluid often creates a noise, typically a hissing sound, which is transmitted through the ground, and although rapidly attenuated can be heard with suitable highly sensitive ground microphones and is therefore useful to field crews as a means of locating leaks. Unfortunately, the sound levels can be grossly distorted by underground heterogenities, and can easily be confused or even swamped by other sound sources above ground, and in general ground microphones used like this do not seem to be effective. The invention deals with the problems entailed in this technique by a method-and apparatus -which involves using semi-automated equipment to listen (either simultaneously or sequentially) to the leak sound source (1) from a multiplicity of different positions (as 3) spaced all around the sound source, and by then suitably combining and processing the received signals to provide the desired indication of the source's location.

Described is a system for filtering, segmenting and recognizing objects. The system receives a three-dimensional (3D) point cloud having a plurality of data points in 3D space and down-samples the 3D point cloud to generate a down-sampled 3D point cloud with reduced data points in the 3D space. A ground plane is then identified and removed, leaving above-ground data points in the down-sampled 3D point cloud. The above-ground data points are clustered to generate a plurality of 3D blobs, each of the 3D blobs having a cluster size. The 3D blobs are filtered based on cluster size to generate a set of 3D candidate blobs. Features are extracted from each 3D candidate blob. Finally, at least one of the 3D candidate blobs is classified as a pre-defined object class based on the extracted features.

A system and method for creating an enhanced virtual top-down view of an area in front of a vehicle, using images from left-front and right-front cameras. The enhanced virtual top-down view not only provides the driver with a top-down view perspective which is not directly available from raw camera images, but also removes the distortion and exaggerated perspective effects which are inherent in wide-angle lens images. The enhanced virtual top-down view also includes corrections for three types of problems which are typically present in de-warped images—including artificial protrusion of vehicle body parts into the image, low resolution and noise around the edges of the image, and a “double vision” effect for objects above ground level.
