1. Conveyor
" con#eyor is a common piece of mechanical handling e$uipment that mo#es materials from one location to another. %on#eyors are especially useful in applications in#ol#ing the transportation of hea#y or bul&y materials. %on#eyor systems allow $uic& and efficient transportation for a wide #ariety of materials which ma&e them #ery popular in the material handling and pac&aging industries. 'any &inds of con#eying systems are a#ailable and are used according to the #arious needs of different industries.

2. %ylinder
Pneumatic cylinder(s) ,sometimes &nown as air cylinders- are mechanical de#ices which use the power of compressed gas to produce a force in a reciprocating linear motion.
i&e hydraulic cylinders something forces a piston to mo#e in the desired direction. The piston is a disc or cylinder and the piston rod transfers the force it de#elops to the ob/ect to be mo#ed. 0ngineers sometimes prefer to use pneumatics because they are $uieter cleaner
and do not re$uire large amounts of space for fluid storage.
Because the operating fluid is a gas lea&age from a pneumatic cylinder will not drip out and contaminate the surroundings ma&ing pneumatics more desirable where cleanliness is a re$uirement.
"lthough pneumatic cylinders will #ary in appearance sie and function they generally fall into one of the specific categories shown below. owe#er there are also
numerous other types of pneumatic cylinder a#ailable many of which are designed to fulfill specific and specialied functions.
Single-acting cylinders
(ingle3acting cylinders ,("%- use the pressure imparted by compressed air to create a dri#ing force in one direction ,usually out- and a spring to return to the home position. 'ore often than not this type of cylinder has limited extension due to the space the compressed spring ta&es up. "nother downside to ("%s is that part of the force produced by the cylinder is lost as it tries to push against the spring.
Double-acting cylinders
*ouble3acting cylinders ,*"%- use the force of air to mo#e in both extend and retract stro&es. They ha#e two ports to allow air in one for outstro&e and one for instro&e. (tro&e length for this design is not limited howe#er the piston rod is more #ulnerable to buc&ling and bending. "dditional calculations should be performed as well.
Telescoping cylinders also &nown as telescopic cylinders can be either single or double3 acting. The telescoping cylinder incorporates a piston rod nested within a series of hollow stages of increasing diameter. 5pon actuation the piston rod and each succeeding stage telescopes out as a segmented piston. The main benefit of this design is the allowance for a notably longer stro&e than would be achie#ed with a single3stage cylinder of the same
collapsed ,retracted- length. +ne cited drawbac& to telescoping cylinders is the increased potential for piston flexion due to the segmented piston design. %onse$uently telescoping
cylinders are primarily utilied in applications where the piston bears minimal side loading.
6. RGB sensor
The RGB color model is an additi#e color model in which red green and blue light are added together in #arious ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additi#e primary colors red green and blue.
The main purpose of the RGB color model is for the sensing representation and display of images in electronic systems such as tele#isions and computers though it has also been used in con#entional photography. Before the electronic age the RGB color model already had a solid theory behind it based in human perception of colors.
RGB is a device-dependent color model! different de#ices detect or reproduce a gi#en RGB #alue differently since the color elements ,such as phosphors or dyes- and their response to the indi#idual R G and B le#els #ary from manufacturer to manufacturer or e#en in the same de#ice o#er time. Thus an RGB #alue does not define the same color across de#ices without some &ind of color management.
4. 7roximity (ensor
" proximity sensor is a sensor able to detect the presence of nearby ob/ects without any physical contact.
" proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation ,infrared for instance- and loo&s for changes in the field or return signal. The ob/ect being sensed is often referred to as the proximity sensor8s target. *ifferent
proximity sensor targets demand different sensors. For example a capaciti#e or photoelectric sensor might be suitable for a plastic target9 an inducti#e proximity sensor always re$uires a metal target.
The maximum distance that this sensor can detect is defined nominal range. (ome sensors ha#e ad/ustments of the nominal range or means to report a graduated detection distance. (ome &now these process as thermosensation.
7roximity sensors can ha#e a high reliability and long functional life because of the absence of mechanical parts and lac& of physical contact between sensor and the sensed ob/ect.
7roximity sensors are commonly used on smartphones to detect ,and s&ip- accidental touchscreen taps when held to the ear during a call.:1; They are also used in machine
#ibration monitoring to measure the #ariation in distance between a shaft and its support bearing. This is common in large steam turbines compressors and motors that use slee#e3
type bearings.
