a hot wire mass airflow sensor determines the mass of air flowing into the engine’s air intake system. the theory of operation of the hot wire mass airflow sensor is similar to that of the hot wire anemometer which determines air velocity .
data logger cube storing technical and sensor data. a data logger also datalogger or data recorder is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. increasingly, but not entirely, they are based on a digital processor or computer .
sometimes, the sensor may become burnt or worn out - or just die of old age at high mileage. one likely cause of crankshaft position sensor failure is exposure to extreme heat. others are vibration causing a wire to fracture or corrosion on the pins of harness connectors. many modern crankshaft sensors are sealed units and therefore will not be .
a lane detection system used behind the lane departure warning system uses the principle of hough transform and canny edge detector to detect lane lines from realtime camera images fed from the front-end camera of the automobile. a basic flowchart of how a lane detection algorithm works to help lane departure warning is shown in the figures.
a proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. a proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation infrared, for instance , and looks for changes in the field or return signal.
a collision avoidance system cas , also known as a precrash system, forward collision warning system, or collision mitigation system, is an automobile safety system designed to prevent or reduce the severity of a collision. in its basic form, a forward collision warning system monitors a vehicle's speed, the speed of a vehicle in front of it, and the distance between the vehicles, to provide .
the lexus ls japanese: レクサス・ls, rekusasu ls is a full-size luxury sedan f-segment in europe serving as the flagship model of lexus, the luxury division of toyota.for the first four generations, all ls models featured v8 engines and were predominantly rear-wheel-drive, with lexus also offering all-wheel-drive, hybrid, and long-wheelbase variants.
the vibration of the probe tends to eliminate build-up of material on the probe element. vibrating level sensors are not affected by dust, static charge build-up from dielectric powders, or changes in conductivity, temperature, pressure, humidity or moisture content. tuning-fork style vibration sensors are another alternative.
a screening machine consist of a drive that induces vibration, a screen media that causes particle separation, and a deck which holds the screen media and the drive and is the mode of transport for the vibration. there are physical factors that makes screening practical.
the simplest resistance-thermometer configuration uses two wires. it is only used when high accuracy is not required, as the resistance of the connecting wires is added to that of the sensor, leading to errors of measurement. this configuration allows use of 100 meters of cable. this applies equally to balanced bridge and fixed bridge system.
in 2014, phase one launched a medium format digital back with a cmos/active pixel sensor: the iq250. all phase one digital backs launched prior to the iq250 have sensors based on the ccd charge-coupled device technology. in 2015, phase one introduced the xf camera system.

the distributor cap is a prime example of a component that eventually succumbs to heat and vibration. it is a relatively easy and inexpensive part to replace if its bakelite housing does not break or crack first. carbon deposit accumulation or erosion of its metal terminals may also cause distributor-cap failure.
network synthesis is a design technique for linear electrical circuits.synthesis starts from a prescribed impedance function of frequency or frequency response and then determines the possible networks that will produce the required response. the technique is to be compared to network analysis in which the response or other behaviour of a given circuit is calculated.
