GLOSSARY

 

 

 

Simultaneous

To take place at the same time.

Sleeve

A thin hollow material that is inserted onto another to provide proportionate spacing.

Snap Ring

A circular clip that may be applied to a shaft, etc. to prevent another object from moving - used

to retain objects in position.

 

Solid

An item that is not porous.

 

An item that is not transparent or translucent.

 

Spacer

Any object of purpose to maintain a specific distance from two other objects - example: a

sleeve or washer.

 

Spindle

A shaft or rod that is fixed on one or both ends and spins on its axis while maintaining its

projection.

 

 

(Static Random Access Memory) A type of memory that is faster and more reliable than the

SRAM

more common DRAM. The term static is derived from the fact that it doesn’t need to be

 

refreshed like DRAM.

Stainless Steel

A shiny, mirror-like carbon steel alloyed with chromium to inhibit rust.

Steel

Metal that contains a specific percentage of carbon. The percentage of carbon determines its

strength, in addition to how prone it is to rust.

 

Stepper Motor

An electrical motor designed to rotate in both directions and to move in incremented distances.

Sub-Assembly

A group of components assembled to form a complete unit that is a part of a larger unit.

Switch

A small mechanical device when altered sends an electrical signal to influence a

predetermined activity. Unlike a button or key, switches may have multiple positions.

 

Tag

Relative to RFID, the transmitter/receiver pair of transceiver plus the information storage

mechanism attached to the object. Also referred to as Transponder.

 

 

The printing method that creates an image by transferring ink from a heat activated ribbon

 

onto the media using the heat from a thermal printhead.

 

A printhead is composed of a set of pins referred to as “elements” which may be selectively

Thermal Transfer

heated through electrical induction. Regular paper media is used in this application in

conjunction with the heat sensitive ribbon. The ribbon deposits a coating of dark material onto

 

 

the paper when exposed to intense heat.

 

Thermal transfer printing is more durable than direct thermal printing and is often used when a

 

label needs to endure longer than a year.

Thermodynamics

The science that deals with the relationship of heat and mechanical energy - also the

conversion of one into the other.

 

Threads

The spiral grooves on the shaft of a screw,

Three-Dimensional

The three projectories of an object: X axis is the distance left and right, the Y axis is the

distance up and down, and the Z axis is the distance inward and outward.

 

Torsion Spring

A piece of wire bent into a spiral and connected on each end by different objects to allow them

to be pulled apart and then automatically return to their original position once released.

 

 

A device used to increase or decrease electricity’s voltage and current. The device consists of

Transformer

one or more windings (typically copper) which, the ratio of the number of turns inversely

determines the voltage change. The windings are wrapped around a magnetic core affecting

 

 

magnetic induction.

 

A device used to amplify a signal or open and close a circuit. Is constructed of a

Transistor

semiconductive material and is comprised of three terminals where one can be used to control

 

the flow of current through the other two.

Translucent

When a medium is of a condition so as to allow light to filter.

Transparent

When a medium is of a condition so one can see through it unfettered.

Transponder

Relative to RFID, the transmitter/receiver pair of transceiver plus the information storage

mechanism attached to the object. Also referred to as Tag.

 

Tread

The act of an object making repetitive contact upon another that is in motion.
