It works by firing pulses of laser light (often in the near-infrared spectrum ... typically switch from the main wide-angle sensor to a telephoto module. The lenses used in the telephoto modules ...

These models detect shaft rotation and display RPM on an LCD or LED screen. For example, an infrared module ... tachometer capable of measuring speeds up to 800 RPM using a PSoC5LP microcontroller.

RPM Drill Hole 4 (AN-24-05), located 400 meters ... up to 732 microns in size were identified and measured throughout the 402-meter hole, confirming consistent style of mineralization across ...

RPM Drill Hole 4 (AN-24-05), the fifth and final hole of Phase 1, was a significant 400-meter step-out to the north of the RPM Discovery Holes 1, 2, and 3. The drill hole intersected abundant ...
