CDEX Inc. (CEXI), which operates in the same industry as innovative chemical detection companies like RAE Systems, Inc. (RAE) and Landauer, Inc. (LDR), announced that it would demonstrate its Valimed MVS’ life-saving capabilities at the upcoming ASHP Conference in Las Vegas on December 7-9, 2009.

CDEX Inc. (CEXI) (www.cdexinc.com) will demonstrate its ValiMed™ MVS with new onsite data collection options at the ASHP Conference (Venetian Hotels & Sands Expo Center) in Las Vegas on December 7-9, 2009. Dennis Quaid, representing the Dennis Quaid Foundation, will provide a keynote address at the Conference. CDEX invites all those interested in medication safety to stop by Booth # 743 and learn how ValiMed MVS is saving lives in major hospitals today.

“The ASHP Mid-Year meeting presents an opportunity for CDEX to inform the Directors of Pharmacy from the nation’s hospitals about the benefits of incorporating the ValiMed MVS into their pharmacy workflow,” said Greg Firmbach, CDEX Senior VP. “ValiMed MVS is increasing overall patient safety as a final check in the prevention of human error in the compounding of high-risk medications and as the central validation point for the disposal of narcotics as part of a narcotic diversion prevention program.”

Worldwide studies continue to show that human errors in the compounding of high-risk medications occur frequently and result in permanent harm to patients throughout the world and that the diversion of medical narcotics is a continuing problem. ValiMed MVS is a technological safety net that provides protection for patients, pharmacists and hospitals.

RAE Systems Inc. (RAE), which competes with innovative chemical detection companies like CDEX, Inc. (CEXI) and other companies like Landauer, Inc. (LDR), announced its new RDK Ruggedized Host controller for AreaRAE toxic gas and radiation sensor networks.

RAE Systems Inc. (RAE), a leader in delivering innovative sensor solutions to serve energy, hazardous material management, industrial safety, government safety and environmental markets worldwide, introduced the new RDK Ruggedized Host a new host controller for AreaRAE toxic gas and radiation sensor networks.

The new RDK Ruggedized Host consists of a ruggedized laptop computer with an embedded RAELink wireless modem and pre-configured ProRAE Remote software. The controller provides real-time communication with up to 64 remote monitors as well as logging of sensor data for historical viewing and interfacing with third-party software. The embedded RAELink modem provides the network with a two-mile range giving incident commanders the ability to manage the sensor system from the “safe zone.” When connected to the Internet the controller can push data over a secure web browser for real time use by remote specialists, plus it can send alarm conditions to cell phones via text messages. Applications for the new ruggedized host include hazardous materials response, public venue protection and short-term industrial deployments as well as mobile network applications.

“We developed the RDK Ruggedized Host in response to requests from first responders who needed a more versatile command platform,” said Bobby Sheikhan, RAE Systems’ wireless products manager. “The new controller has one-button operation, is vibration and shock resistant, and the flexible network configuration can be easily changed to merge with other AreaRAE networks in mutual aid situations.”

The new host controller supports a wide range of wirelessly enabled sensors including AreaRAE Steel and many gas- and radiation-detection instruments that interface to the network through the RAELink 3 modem. Housed in a MIL-STD 810F magnesium case that is IP-54 rated, the RDK Ruggedized Host can withstand harsh environments with temperatures ranging from -4 degrees Fahrenheit to +131 degrees Fahrenheit. It also features a sunlight-readable touchscreen and electromagnetic shielding.

The RDK Ruggedized Host Kit includes the controller with embedded RAELink device bay, removable DVD-ROM drive, universal AC adapter, right angle antenna, back up software and deluxe carrying case. Additional options include a GPS module. Prices start at $11,130.
