LaCoste's most famous invention is the ship- and aircraft-mounted gravimeter. These revolutionized exploration for minerals by allowing wide-ranging geological surveys. The chief problem that Lacoste defeated was to distinguish the accelerations of the vehicles from the accelerations due to gravity, and measure the minute changes in gravity.
Recently, the SGs, and broadband three-axis seismometers operated in gravimeter mode, have begun to detect and characterize the small gravity signals from earthquakes. These signals arrive at the gravimeter at the speed of light, so have the potential to improve earthquake early warning methods. There is some activity to design purpose-built ...
Gravimeter with variant of Repsold pendulum The large increase in gravity measurement accuracy made possible by Kater's pendulum established gravimetry as a regular part of geodesy . To be useful, it was necessary to find the exact location (latitude and longitude) of the 'station' where a gravity measurement was taken, so pendulum measurements ...
Gravimeter, an instrument for measuring the local gravitational field Hydrometer , referred to in pipeline work as a gravitometer Topics referred to by the same term
These new surroundings hastened the development of an existing idea: an adding machine. His new job gave him the opportunity to build his prototype. Accuracy was the foundation of his work. He made his design drawings on metal plates to prevent distortion. Burroughs filed his first patent for the invention of a "calculating machine" in 1885. It ...
Jacques de Vaucanson (French: [jak də vocɑ̃sɔ̃]; February 24, 1709 – November 21, 1782) [1] was a French inventor and artist who built the first all-metal lathe.This invention was crucial for the Industrial Revolution.
The Lunar Traverse Gravimeter was a lunar science experiment, deployed by astronauts on the lunar surface in 1972 as part of Apollo 17.The goal of the experiment was to use relative gravity measurements to infer potential attributes about the geological substrata near the Apollo 17 landing site.
Bradford Parkinson (born February 16, 1935) is an American engineer and inventor, retired United States Air Force Colonel and Emeritus Professor at Stanford University.He is best known as the lead architect, advocate and developer, with early contributions from Ivan Getting and Roger Easton, of the Air Force NAVSTAR program, better known as Global Positioning System.
