The development of the GOLD system is a revolutionary step toward conducting global atmospheric research with UAV platforms, and it is an enabling step in the development of a space-based O 3 and aerosol lidar system. Both of these steps are important contributions to the long-range objectives of NASA's Earth System Science
Color sensors detect the color of a surface. The sensors cast light (red, green, and blue LEDs) on the objects to be tested, calculate the chromaticity coordinates from the reflected radiation and compare them with previously stored reference colors. If the color values are within the set tolerance range, a switching output is activated.

I have questions regarding to your Long range IR beam break detector circuit. I'm using your circuit as my project for my Final year project. I have a little problem with the transmitter. I'm using a regular IR LED. When it transmit, the receiver starts to blinking.
A long-range communications apparatus utilizing modulated-reflector technology is described. The apparatus includes an energy-transmitting base station and remote units that do not emit radiation in order to communicate with the base station since modulated-reflector technology is used whereby information is attached to an RF carrier wave originating from the base station which is reflected by ...
Nov 08, 2017· How do they work? How easily can they spot radar detector users? How effective are "undetectable" radar detectors at avoiding detection from a radar detector detector? Let's take a look and cover everything you need to know about radar detector detectors. Two Most Popular Radar Detector Detectors. One of the most popular early RDD's was ...
The best radar detectors spot radar at long range and filter out false alerts. They balance sensitivity (range) with selectivity (filtering). The most desirable ones use GPS to lock out false alerts caused by radar-controlled automatic door openers. Drive past any store using a non-GPS detector and it will alert to the store's radar.

Gold Detector Deep Ground Gold Search/Underground Water Metal Detector/Cheap Price Underground under Water used Metal Gold Detector Description This underground metal detector is a kind of professional detecting equipment. It can scan the metal objects easily and quickly, which can help professionals a lot when they do the research.
The index of refraction ranges from approximately 1.45 - 2 for visible materials and 1.38 - 4 for IR materials. In many cases, index of refraction and density share a positive correlation, meaning IR materials can be heavier than visible materials; however, a higher index of refraction also implies diffraction-limited performance can be achieved with fewer lens elements – reducing overall ...
Aug 10, 2019· The Updatable IVT filter is designed to automatically reduce false alerts from moving in-vehicle technology sources such as collision avoidance systems and adaptive cruise control. There is going to be zero disturbance coming from nearby cars. Be The King on The Road. If you have this device, you will no longer be bothered by cop radars.
