Smart Headlight

YouTube Channel : LabEquipment

  • The low down
  • In rain and snow conditions headlights reflect off of the precipitation back to driver
  • Carnegie Mellon professor and his team are working on ‘smart’ headlights that can streamlight in between the drops
  • Significance
  • The system consists of a co-located imaging and illumination system– camera, projector, and beamsplitter
  • The camera uses a 5 ms exposure time and the system has a total latency of 13 ms when the system runs at 120Hz. with an operating range about 13 feet in front of the headlights
  • The camera images the precipitation at the top of the field of view, the processor can tell where the drops are headed and sends a signal to the headlights, headlights then make their adjustments and react to dis-illuminate the particles all in about about 13 ms.
  • Simulations
  • Computer simulations predict system effectiveness for different systems set ups during a heavy rainstorm [25 mm/hr] on a vehicle traveling 30 km/hr
  • Simulations show that a system operating near 1,000 Hz, with a total system latency of 1.5 ms, and exposure time of 1 ms can achieve 96.8% accuracy, with 90% light throughput expected
  • The system would still have a significant [>= 70%] visibility improvement at 400 Hz
  • A prototype system has already validated simulations on laboratory-generated rain operating at 120 Hz
  • Simulations show that it is possible to maintain light throughput well above 90 percent for various precipitation types
  • Of Note
  • The prototype consists of a camera with gigabit ethernet interface (Point Grey, Flea3), DLP projector (Viewsonic, PJD62531), and desktop computer with Intel architecture (Intel i7 quad core processor).
  • The team says that it may take three to four more years of development and “commercializing it as a product will take additional years.”

New mineral in old rock

  • The low down
  • A meteorite that fell in 1969 as an exploding fireball in the skies over Mexico, scattered thousands of pieces of meteorites across the state of Chihuahua
  • It is largest carbonaceous chondrite ever found on our planet and is considered by many the best-studied meteorite in history
  • Scientists have now discovered a new mineral embedded in that meteorite
  • Panguite is an especially exciting discovery since it is not only a new mineral, but also a material previously unknown to science
  • The mineral could be among the first solid objects formed in our solar system, dating back to over 4 billion years ago, before the formation of Earth and the other planets.

Looking back

  • July 16, 1994 : 18 years ago : Shoemaker-Levy Comet : The first of 21 asteroids, major fragments of the comet Shoemaker-Levy 9 broken-up 2 years earlier, hit Jupiter, creating a 1200-mile wide fireball 600 miles high to the joy of astronomers awaiting the celestial fireworks, giving scientists their first chance to observe such a collision as it happened, and others through July 22. Jupiter is a gas giant, made up mostly of hydrogen and helium in gas and liquid form.When we observe Jupiter, we are looking not at a solid surface, but a banded atmosphere with swirling clouds and huge storms.
