| Shell Canada and Pulsearch Navigation Systems of Calgary have developed an integrated real time differential GPS and barometry system. |
| Later he experimented in barometry, and pursued investigations in mechanics. |
| He was granted a large number of patents for inventions and refinements in the fields of elasticity, optics, and barometry. |
| However, further thought shows that such an application of luminescent barometry is not to be undertaken lightly. |
| The planned implementation of automated digital barometry entry into the METAR will essentially eliminate the possibility of such errors occurring upon its installation at each site. |
