They register the radiation from every journal bearing that passes over them. If a bearing reaches the maximum temperature for safe travel, the detector will flag and count it as a defect. Because bearings can burn off in as little as three minutes, hotbox detector installations are extremely common on many railroads.
Rear Occupant Alert (ROA) is motor vehicle manufacturer Hyundai Motor Company's automated vehicle alert system to detect the presence of an occupant in the rear seat of a passenger motor vehicle. [1] The basic system uses door logic. [2] If a rear door is opened and closed and the vehicle is turned on, a dashboard alert will activate when the ...

A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine" Graphical tell-talesA tell-tale, sometimes called an idiot light [1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
Radiation monitors in general have a number of process-control applications in nuclear power plants; [9] a major CPAM application in this area is the monitoring of the air intake for the plant control room. In the event of an accident, high levels of airborne radioactivity could be brought into the control room by its HVAC system; the CPAM ...

Electric eye for a garage door opener. An electric eye is a photodetector used for detecting obstruction of a light beam. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light beam.
