Latest Patents
Jeffery M Johnston holds a patent for a "Tow mechanism for resistivity mapping apparatus." This invention includes a tow mechanism designed for use by a human operator to move the mapping apparatus over a surface while measuring the resistivity of soils. The mechanism features a generally triangular-shaped tow ring that can be engaged by the operator's battery belt, harness, or pack-frame. The tow ring is equipped with two opposing hooks at a vertex for receiving a loop from a tow line. This tow line connects to a cable depressor weight, ensuring that the resistivity mapping apparatus remains close to the earth during towing. Additionally, a communication cable within the tow line preferably comprises an optical fiber, which transmits signals from the receiver to a data logger carried by the operator.
