Louis Giokas

Louis Giokas started out in the aerospace business holding positions in development and management.  At General Electric Aerospace (now part of Lockheed Martin) he held positions of software engineer, systems engineer and staff engineer. While there he worked on spacecraft and military systems. Prior to that he worked for companies such as Sperry UNIVAC and Link Simulation Systems, also working or spacecraft and military systems. Over the past two decades he has worked in the database management software area for Oracle and IBM. Over the past several years he has worked on development projects and has consulted in a number of different areas, including embedded systems. He is a long standing member of the Institute of Electrical and Electronics Engineers (IEEE). Currently, he is the secretary of the Fox Valley Subsection of the Chicago Section and chairman of the Computer Society of the Chicago Section. He has a degree in Computer Science from Villanova University and is pursuing a MS in Applied Statistics from DePaul University.

September 15 – Day 5 – Programming the Chip

Now that we have an algorithm developed, debugged and laid out in our design tolos we are ready to transfer that to the FPGA chip and run our algorithm there. We will also discuss the process of reprogramming the chip during operations and will discuss how that might be used.

September 14 – Day 4 – Synthesis and Layout

Once a design has been developed in a HDL and tested and verified, we need to lay it out on the chip. This is analogous to layout for ASICS but it is not as complicated since we are using an existing regular structure. Layout is important because of the effect on performance and the interaction of...

September 13 – Day 3 – HDL

Algorithms for FPGAs are specified via a Hardware Description Language (HDL). We will look at a couple of these, VHDL and Verilog. Many design tool sets support both. The one you use will depend on standards and skills available in your shop. We will also look at some of the tools used to convert...

September 12 – Day 2 – Design Flow

The flow of design tasks will be somewhat dependent on the FPGA vendor and tool set, but there are some general steps that are generally followed. We will start with these general steps and then look at some of the particular vendors. There are also various options in the design flow from any...

September 11 – Day 1 – Intro - FPGA Device Description

We start with an introduction to the class of devices called FPGAs. The layout and design of several types and critical parameters will be described and discussed. It is important to understand the way the device is constructed to develop effective algorithms.

August 25 – Day 5 – Available Products and Future Trends

There are a number of available RTLS products in the industry. We will discuss a sampling of those available. In general these are not compatible. We will also discuss standards that should lead to interoperability between these. As mentioned, there are always new technologies being developed and...

August 24 – Day 4 – Implementation Issues

Applying location services in a healthcare environment is a major task. There are many considerations. These might include how to apply the tags and locate the sensors as well as security and management of the location services system as a whole. We will discuss these issues and work through some...

August 23 – Day 3 – Systems and Software

The tags and sensors are important, but they do not actually do the job by themselves. All of the data collected by the sensors are collected, stored and processed by multiple layers of software which allows a full picture of the collection of things being monitored to be given. This includes the...

August 22 – Day 2 – Tags and Sensors

At base, location services rely on the tags and sensors used. There are many types already in use, and more are being developed. We will concentrate on those used in the healthcare environment. One of the most important aspects in healthcare is accuracy of location and we will address these issues...

August 21 – Day 1 – Overview

This lecture will concentrate on a general description of RTLS. This will include an introduction into the general technologies used, and the implementation issues generally encountered. RTLS is much more than just tags and sensors and we will take a systems approach to understanding the topic.
