D.L.S. now offers TestView™ Service
 |
 |
Save time and money by viewing, from your own office, your EMC compliance test being performed at D.L.S. Electronic Systems, Inc. in Wheeling, IL. TestView™ is a secure video system that enables clients to log in to D.L.S.’s test site from their own location and view their equipment being tested in real time. For example, a client could see a test engineer performing DO 160 Section 22 indirect lightning testing, as shown in the above photo. TestView™ allows the client to control the camera by making it zoom or pan to witness any part of their test at any time, as shown in the insert above. It is zoomed in on the test panel which shows the generator settings. For more information call Jack Black at 847-537-6400 or go to www.dlsemc.com/testview.

D.L.S. offers Early Design Evaluation program for medical products
In order to help a medical device meet regulatory compliance in a time efficient, cost-saving way, we created an Early Design Evaluation (EDE). This program incorporates an early stage design review and evaluation addressing the electromagnetic compatibility and the product safety requirements of electrical and electronic devices. This program covers world wide EMC and Safety directives, including but not limited to, FCC, CE, UL, CSA, ACA, FDA, FAA, IEC, CCC and other government and regulatory agencies. This process greatly reduces the time to market by eliminating design flaws and identifying applicable standards early in the design phase.
The EDE Four-Point Program:
Initial Review The initial review develops a brief description of the product or device, including its intended use.
EMC and Product Safety Compliance Review EDE Project leader and EDE Specialist review product or device for applicable EMC Directives and Standards, Review of individual standards, and Review Description of Testing Methodology.
EMC and Product Safety Design Evaluation Detailed analysis of the product or device for EMC and Product Safety issues by EDE EMC Specialist and Product Safety Specialist. Review of EMC and Product Safety design issues/solutions:
- Board/Component related
- Cable Related
- Enclosure Related
- System Related
A Final Report Is issued by EDE Project Leader. Specifically mentioned are recommendations in the areas reviewed and discussed. Included are proposals related to additional work needed for compliance to applicable standards.
Results We have found by addressing EMC and Product Safety requirements early in the design stage, we have saved many medical manufactures the cost, frustration, and loss of time of trying to add fixes and design changes to a product that is out of limits or that requires Product Safety changes.

UL approves D.L.S. Conformity Assessment, Inc.
for Safety Testing
Underwriters Laboratories has officially accepted D.L.S. Conformity Assessment, Inc., a subsidiary of D.L.S. Electronic Systems, Inc., into their Third Party Test Data Program. This program allows D.L.S. to test directly to UL standards for ITE, audio/video, medical devices and equipment, and laboratory test and measurement equipment for formal listing.
Manufacturers will be able to complete their EMC, Safety and Environmental testing requirements all under one roof, saving them time and allowing them to speed their product to market. This program provides for a formal UL listing for U.S. and Canadian safety standards. Please go to www.dlsemc.com/ul for more information on this new program.

Influencing Wireless Medicine
In response to Medical Design Technology's question, "How are you influencing wireless medicine?" our Senior EMC Test Engineer and OATS manager, Bill Stumpf, responded with the following:
Wireless technologies have an important role in medical applications such as asset tracking (RFID), wireless controllers, patient monitoring, two-way radios, and wireless data transfer. It is imperative that manufacturers of these wireless medical devices address the issues and concerns relevant to the safe and effective use of radio frequency (RF) as required by the many Medical Standards and the hospital environment. As an Electromagnetic Compatibility and Product Safety lab offering testing, consulting, and certification of wireless devices, we get manufacturers through regulatory compliance hurdles. In this way we provide a streamlined process of getting new wireless medical technologies on the market in a timely and cost effective manner. By testing for RF emissions, Immunity to Interference, and Product Safety, we are helping to provide assurance that the wireless device will work reliably in the environment for which it is intended, and that it will be safe for the user and patient. As a test lab we are helping to make these wireless technologies available to the medical industry.
