Dredging Up The...FUTURE

People around the world are aware of the devastation caused by Hurricane Katrina along the coast of Louisiana, Mississippi, Alabama, and Florida. What started around the southeastern Bahamas on August 23, 2005 as Tropical Depression number 12, quickly became the fourth hurricane of the season just 48 hours later. When her catastrophic winds finally subsided,…

New Spherical Optics Technology for Sensing in Small Areas

The Challenge Diffuse sensors enjoy great popularity with users. With diffuse sensors, pulsed light from an emitting diode falls on an object of any shape or color and is reflected in a diffuse manner to a light-receiver, which is located in the same device (fig.1). If the intensity of the received light is sufficient, the…

A User's Guide to Configuring Serial Ports for DirectLOGIC PLCs: A Two Part Series

The capabilities of Port 2 of the DL06, DL250-1 and DL260 CPUs are often overlooked when designing a process control network. Like Port 1, Port 2 can be used for programming the CPU or connecting other RS-232 devices, such as an operator interface panel, to the PLC. Unlike Port 1, Port 2 supports different types…

The Evolution of Wireless Communication

In 1901, Guglielmo Marconi used Morse code to communicate the letter “s”. This transmission was an analog equivalent of a “digital” signal. By 1914, the Marconi Company was engaged in experimental voice transmissions that laid the groundwork for broadcast radio. With the advent of short wave radio, costs came down and reliability went up, ensuring…
