Latest Patents

One of Logan's notable inventions is the "Stabilizer for Geophone." This invention presents a unique stabilizer designed to minimize the movement of a geophone after its deployment in marine environments, which are often affected by water currents and turbulence. The stabilizer features a bulb-shaped body equipped with fin-shaped lobes, allowing it to effectively anchor the geophone. It includes an axial cavity specifically for receiving the geophone housing, promoting stability during operation.

Additionally, Logan has developed a "Geophone Spring" intended for use in seismometers. This spring design suspends one body relative to a fixed reference point within a housing, consisting of an outer ring and an inner ring interconnected by numerous arcuate legs. The innovative design of the legs incorporates arcs of varying radii and centers, enhancing the spring's resilience and ensuring a longer useful life by effectively reducing spurious resonance in comparison to previous designs.
