1) Radio controlled

Means by which a material handling device or piece of equipment is controlled by receiving commands via radio frequencies sent to an onboard receiver.  Allows the equipment or device to be controlled remotely and out of harm's way.

2) Quality control

The use of sensors to detect the presence of an object's component part, fill level, or dimensional tolerance for the purposes of providing process quality control.

3) Radio control

A communication medium through which motor, drives and controls receive direction over radio waves emitted from hand-held and equipment mounted transmitters.

4) Radio frequency

A communication medium by which motor and controls are directed by means of high and low frequency radio transmission directives.  Often referred to as a Wireless Controls .

5) Pendant station

Also referred to as a "pushbutton station".  An electrical control device consisting of pushbutton-operated contacts in an enclosure used by the operator for control of the powered motions of the crane, hoist and other auxiliary equipment.

6) Push driver

A computer-controlled arm that can push items at a right angle from a conveyor line to the desired location.

7) Reliability

The measure of how well a material handling device or system will perform in a production situation.  Measure is based upon how well the device or system performs without interruption in service due to mechanical or control failure.

8) Project management

Project management is a combination of project evaluation and scheduling with the additon of project coordination and control.  Effective project managment takes into account cash flow and present worth, decision tree analysis, critical resource analysis and critical path scheduling.

9) Pneumatic tube system

Also referred to as a vacuum tube system. In all but the simplest of applications, the pneumatic/vacuum tube system however, such as at drive through banks, these systems are capable of very complex networks (upwards of 1000 origin/destination stations) involving branching, switching or merging. The computer control in modern systems make these systems very flexible. The carrying units appear much like a projectile that has to be opened so that the load to be transported can be placed inside. There are units installed where carriers approach 12 inches in diameter and are capable of carrying fairly large parts. The speed of a pneumatic/vacuum system averages 1500 fpm.
