How Do Self-Driving Cars “See” in Snow? To navigate safely, autonomous cars first have to “see” the world around them. Through an integrated system of camera, lidar, and radar sensors, self-driving vehicles are constantly scanning the environment to make informed decisions. But what happen...
How different parts and sensors work in your car. Symptoms, testing, common problems, illustrations, replacement
The parking sensor also called "parking aid", is mainly composed of ultrasonic sensors, controllers, and displays. It helps the driver "see" the invis...
The emission control system in modern cars consists of a catalytic converter, a collection of sensors and actuators, and a computer to monitor and adjust everything. For example, the catalytic converter uses a catalyst and oxygen to burn off any unused fuel and certain other chemicals in the ...
There are some additional sensors, timers and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner. Although this is a conventional setup for an air conditioner, there are a couple of variations you should know about. Window air ...
which are continuous and varying. Thermocouples that are used in gas hot water heaters offer a good example of analog sensors. The water heater's pilot light continuously heats the thermocouple. If the pilot light goes out, the thermocouple cools, sending a different analog signal that indicates...
They are subject to geofencing, unlike a fully autonomous Level 5 car that could go anywhere. How Do Autonomous Cars Work? Autonomous cars rely on sensors, actuators, complex algorithms, machine learning systems, and powerful processors to execute software. Autonomous cars create and maintain a ...
Devices like the Alcosensor III and IV use fuel cell sensors. The fuel cell has two platinum electrodes with a porous acid-electrolyte material sandwiched between them. As the exhaled air from the suspect flows past one side of the fuel cell, the platinum oxidizes any alcohol in the air to...
Systems like these have settings that dictate general behaviour but - much like Magnetorheological dampers - operation varyies constantly. In the case of Damptronic, the damper’s control system takes into account readings from various accelerometers and ride height sensors. ...
Load sensors Motion sensors Accelerometers These devices measure the acceleration in a particular direction. This data can be used to determine the probability of injury. Acceleration is the rate at which speed changes. For example, if you bang your head into a brick wall, the speed of your...
