A Privacy Treatise

Written by Kathleen Pierz

Continued from page 1

Today, for most types of personal and professional contact information, there are two options: listed and not listed. Many other communications points are “unlisted” inrepparttar sense that they are not easily available in a directory such as email or websites. These other communications methods are more likely to be considered permissions-based devices. Those communication methods that requirerepparttar 133521 subscriber to provide their specific contact information to those they wish to reach them.

Privacy is what your customer says it is Legal and regulatory definitions ultimately matter less than what your customer believes or expects. On most US wireless subscriber contracts today, text appears that states that upon signingrepparttar 133522 contractrepparttar 133523 subscriber grants their express permission for their number to be utilized for directory purposes. This does not mean that adding mobile numbers torepparttar 133524 DA/DQ database will be easy, or even go unchallenged. In fact very few consumers are aware ofrepparttar 133525 fact that their mobile numbers could, technically, be listed today. Consumers perceive their mobile numbers to be private independent of their current legal status consumers believe them to be private. Any across-the-board move to change this would likely meet with not only customer opposition but possible regulatory intervention.

This discussion extends beyondrepparttar 133526 introduction of wireless numbers inrepparttar 133527 US DA/DQ database. It will ultimately expand to includerepparttar 133528 range of possible ways in which one can be contacted. A viable model must be found and implemented that both provides for connectivity, but that also gives consumers control over who may contact them, when, where and how. This is especially true inrepparttar 133529 US market, givenrepparttar 133530 combination of over zealous telemarketing efforts and a general disregard for personal privacy (in contrast to Scandinavian countries where more than 90% of all phone numbers, including mobile phones, are listed). There is a huge upside (revenues from WDA are estimated at $3.4 Billion annually) and a huge downside (inability to launch WDA, erosion in fixed line database, inability to launch future services, increased regulation) ifrepparttar 133531 market fails to achieverepparttar 133532 precise mix of communications and control.

A New Model for Privacy AND Communication Providing greater consumer privacy and better connectivity atrepparttar 133533 same time are not mutually exclusive ends. This issue extends beyond wireless numbers to include a range of personal contact points. If directory providers are not providing it, regulators have a demonstrated zeal for stepping in and regulating privacy – which can ultimately be torepparttar 133534 detriment of all parties. Without a change, call volumes will decline, and we argue, out ability to communicate with one and other will be increasingly limited.

The Formula Carriers and DA/DQ providers who can integraterepparttar 133535 following five points, into their service and effectively communicating them to consumers will ultimately be successful at providing better services to their customers. 1. Consumers want control 2. Consumers will not tolerate abuse 3. Information must become individual-centric rather than location centric 4. Timing: Now isrepparttar 133536 time to act 5. Education: Consumers Need to Know

Industrial ppm CO measurements

higher temperature coefficient, this leads to zero instability making it unsuitable for our task. Carbon and chemical filters are often attached torepparttar face ofrepparttar 133520 sensor or added inrepparttar 133521 sample stream to diminishrepparttar 133522 effects of cross interference to many ofrepparttar 133523 commonly encountered such as H2S, SO2, NO x, etc.. This filter, it’s efficiency and life span can be an important consideration when measuring CO inrepparttar 133524 0-50ppm range. In a number of applications background levels of Hydrogen given off by nearby processes have been found to cause major problems with accurate low level carbon monoxide measurements and alarms. While it is possible for hydrogen levels to cause safety concerns that should be reported,repparttar 133525 limit is magnitudes higher than what causesrepparttar 133526 CO alarms to trigger on most instruments. A hydrogen level of as little as 60ppm can triprepparttar 133527 CO alarms of many analyzers. The lower explosive limit (lel)for hydrogen is 4%, ten percent of that l.e.l. would be 4000ppm, so we see thatrepparttar 133528 60ppm is insignificant to personnel safety but remains problematic torepparttar 133529 carbon monoxide measurement. This cross interference can not be easily overcome with chemical filters and therefore required a different approach. It has been found that by measuringrepparttar 133530 hydrogen separately and using that signal in conjunction withrepparttar 133531 mixed CO/H2 signalrepparttar 133532 majority ofrepparttar 133533 interference can be nulled out, again manufactures deal with this differently with varying results. The use of two separate sensors can create a compensation lag time and there may be temperature coefficient differences betweenrepparttar 133534 sensors, either of which will cause errors inrepparttar 133535 readings and provide false alarms. Similar temperature problems can be found with units that use a single sensor but dorepparttar 133536 electronic nulling and temperature compensation remote ofrepparttar 133537 sensor itself.

There are sensors now available that have separate electrodes forrepparttar 133538 H2 and CO/H2 signals withrepparttar 133539 nulling and temperature compensation circuit attached directly torepparttar 133540 rear ofrepparttar 133541 sensor itself. The output of this surface mount board is inrepparttar 133542 millivolt range making it less susceptible to interference and change from wiring, connectors and temperature effects. Each sensor and attached PCB come completely pre-calibrated for H2 cross interference and relative CO output. Only a single calibration gas is required overrepparttar 133543 life ofrepparttar 133544 sensor (2 years) with no need for re calibration ofrepparttar 133545 hydrogen signal nulling found in any ofrepparttar 133546 units put into service. In addition,repparttar 133547 internal chemical filter provides excellent reduction of cross interference due to other common gasses found. This customer replaceable sensor has proven itself over time to provide consistently accurate results in demanding applications against competitors instruments.

Dover Gas Technologies Inc. www.dovergas.com incorporates such a sensor, we believe it best suitsrepparttar 133548 needs addressed above and use it in many of our portable, transmitter, and monitor products for low level ppm CO measurement.
