Under U.S. Food and Drug Administration standards for metric equivalents, a teaspoon is five millimeters and a tablespoon is 15 milliliters. U.S. teaspoons and tablespoons should not be confused with imperial teaspoons and tablespoons, which are measurements used in Britain and some former British countries.
A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding. Only doppler radar-based devices can be detected â other speed measuring devices including those using ANPR, piezo sensors, and VASCAR technology cannot be detected. LIDAR devices require a different type of sensor, although many modern detectors include LIDAR sensors.
Googleâs latest prototype vehicles originally came without a steering wheel and didnât feature brakes that were operable by its human passengers, although it was forced to add such controls so it could legally test the cars on the road. Fordâs pedestrian detection uses two sensors: radar in the bumper and a camera on the windshield. The radar detects an object, and the camera can determine if it is a person crossing the road. When the vehicle detects a pedestrian, it will warn the driver with a light and a sound.
