What is inflammation and the steps in the process of inflammation? We often feel redness, heat, swelling and pain at the site of wounds. Actually this is bodyâs defence mechanism to destroy the pathogen. Tissue damage caused by wound or invading pathogenic organisms induces a complex sequence of events collectively known as inflammation.
A flame detector is a sensor designed to detect and respond to the presence of a flame or fire. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.
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.
