Terms | Definitions |
|---|---|
 Analog Signal | A signal having the characteristic of being continuous and changing smoothly over a given range, rather than switching suddenly between certain levels. |
| Automation | A technique that is used to make a process automatic. |
| Computer Aided Manufacturing (CAM) | Using computers to operate and control machines and processes to manufacture a product. |
| Computer-Integrated Manufacturing (CIM) | A company-wide management philosophy for planning, integration, and implementation of automation. |
| Closed-Loop System | A system that uses feedback from the output to control the input. |
| Digital Signal | A system of discrete states: high or low, on or off, 1 or 0. |
| Efficiency | The ability to bring a desired result with the least waste of time, energy, or material. |
| Electromagnet | A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor, the iron core becomes magnetized. |
| Experimentation | Try out a new procedure, idea, or activity. |
| Feedback | Information about the output of a system that can be used to make adjustments. |
| Flexible Manufacturing Systems (FMS) | The efficient production of small amounts of products. |
| Flowchart | A diagram that shows step-by-step progression through a procedure or system especially using connecting lines and a set of conventional symbols. |
| Fluid Power | Use of liquids or gases under pressure to move objects or perform other tasks. |
| Fuel Cell | Device that combines hydrogen, or other fuels, and oxygen and produces electricity in the process. |
| Hydraulics | Fluid power system that uses water, oil, or another liquid. |
| Icon | A symbol or graphic representation on a screen of a program. |
| Innovation | An improvement of an existing technological product, system, or method of doing something. |
| Input | Information fed into a system. |
| Interface | The place at which independent and often unrelated systems meet and act on or communicate with each other. |
| Invention | A new product, system, or process that has never existed before, created by study and experimentation. |
| Malfunction | To function imperfectly or badly. |
| Normally Closed | The contact of a relay that is closed when the coil is de-energized. |
| Normally Open | The contact of a relay that is open when the coil is de-energized. |
| NTC Resistor | A negative temperature coefficient, also known as a thermistor, is a sensitive resistor whose primary function is to exhibit a change in electric resistance with a change in temperature. |
| Open-Loop System | A control system that has no means for comparing the output with input for control purposes. An open-loop system often requires human intervention. |
| Output | The information produced by a computer. |
| Photocell | A photo-sensitive resistor whose resistance decreases as the light striking the unit increases. |
| Pneumatics | Fluid power system based on the use of air or another gas. |
| Program | Set of instructions that control the operation of a computer. |
| Reed Switch | An electromagnetically operated switching device. |
| Sensor | A device that responds to a physical stimulus (as heat, light, sound, pressure, magnetism, or a particular motion) and transmits a resulting impulse (as for measurement or operating a control). |
| Software | Programs and other operating information used by a computer. |
| Solar Cell | A device that converts solar radiation into electricity. |
| Switch | A device for making, breaking, or changing the connections in an electrical circuit. |
| System | A group of interacting, interrelated, or interdependent elements or parts that function together as a whole to accomplish a goal. |
| Threshold | A level or point at which something would start or cease to happen or come into effect. |
| Troubleshoot | Locating and finding the cause of problems related to technological products or systems. |
