HUMAN FACTORS ENGINEERING
the design of equipment and environments to promote human health, safety, and well-being; sometimes referred to as ergonomics.
an activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.
the imitation, as closely as possible, of the real-life circumstances in which a solution is intended to be used.
the knowledge, tools, machines, skills, and other things that people make and do to send and receive information.
a device capable of detecting (sensing) changes in its environment; light and movement are examples.
the path by which a message travels from the sender to receiver.
the unlawful acquisition of some one's personal information for use without their consent.
the path by which electric current or pulses flow.
in a computer, the primary circuit board to which all internal componnets are connected either directly or indirectly.
CENTRAL PROCESSING UNIT(CPU)
a specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a "computer within the computer."
the long term storage mechanism of a computer. It holds the computer programs used for word processing, playing games, and other tasks.
a language, used to write computer programs, that can easily be translated into machine language.
A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.
The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.
the number of waves that pass through a given point in one second. It is commonly measured in a unit called hertz. 1Hz is equal to one complete wave cycle in one second.
a unit that collects waves and decodes information contained within those waves.
the superimposition of sine waves on electromagnetic carrier waves.
a device that orbits the Earth and receives messages from one location and transmits them to another.
CHARGE-COUPLED DEVICE (CCD)
a very small solid state panel that contains light sensitive photo-sites or photo-diodes. The CCD uses the photo-sites to convert light into electrical signals transformed into an image.
the technology field focused on sending messages and other in formation using different means.
PRINCIPLES OF DESIGN
the formal rules that guide the design process.
DIGITAL WORK FLOW
the use of computers in each stage of the design process.
the use of lasers to record realistic images of three-dimensional objects.
COMPUTER-AIDED DRAFTING (CAD)
the use of a computer system to produce technical drawings and/or design a product.
the use of 3D CAD drawings to create real models of a product within a sort of time.
the capacity to do work or exert effort.
the use of force to act on an object in order to move move the object in the same direction as the force.
stored energy or energy at rest.
energy in motion.
the measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.
the splitting of the nucleus of an atom.
a method of obtaining energy from waste products
heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.
the passage of electric current through an electrolytic fluid for the purpose of separating molecules.
the amount of resistance the power system must overcome or, alternatively, the amount of force output by the power system: also can be referred to as weight or pressure.
the use of simple machines to multiply the output force of a mechanical system.
a device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.
the use of pressurized liquid or gasses to control and transmit power.
the law that states that if the pressure of a gas increases, the volume decreases (provided that the temperature remains constant).
DIRECT CURRENT (DC)
current flow in which electrons move in only one direction.
ALTERNATING CURRENT (AC)
current flow in which electrons reverse direction at regular intervals.
a circuit in which electricity flows along a single path to more than one device.
a circuit in which electricity flows along more than one path.
the field of knowledge relating to materials as they exists on a molecular or atomic level.
trade of products and services on a global scale.
An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.
the money a business makes after all expenses have been paid
the comparison of the amount of goods produced (output) to the amount of resources (input) that produced them
a production system in which products are made one at a time according to customer's specifications.
a production system in which a limited quantity of a part or product is made. After the production run, the machines are retooled or changed over to accommodate the production of a different part or product.
a production process in which the part or product moves down a line from one station to the next while parts are added.
