CMI Web – Technology First!


Technology solves problems. It creates new modes of operating and thinking. It fuels the future as advancements create efficiencies and new ways of overcoming old obstacles. Thankfully technology isn’t limited to computers and IT. Innovations occur in every industry, providing breakthroughs that advance the industry forward.

The field of medicine has long relied on technology to provide new understandings of the causes of diseases and potential cures. Now there are more discussions on how robots can assist medical caregivers and surgeons with tasks. Telemedicine has been providing better medical care to distant and rural communities for a few years as it connects those areas with medical specialists, regardless of the distance. Now “medical robots” could take this idea a step further and provide a two-way screen and medical monitoring equipment to allow these devices to perform routine rounds at a hospital. And robotic surgery, with its 3-D viewing systems, imaging techniques, specialized instruments and robotic arms, can be performed for a number of complex operations less invasively and with more precision. These technologies hark back to science-fiction but are becoming a science-reality.

Even innovations unrelated to medical breakthroughs can impact disease control and cures. Bill Gates is using his fortune, through the Bill and Melinda Gates Foundation, to seek the eradication of (or at first a severe reduction in the number of deaths from) polio, tuberculosis and malaria through technological innovations. One of those technologies is the development of a super thermo that does not rely on electricity or a battery to keep life-saving vaccines cold for up to 50 days so they can be transported to and used in remote locations. Another is a toilet that does not require plumbing. Better sanitation and toilets can prevent disease when used in communities where currently human waste fills local streams become breeding grounds for disease. Continue reading

Four Solenoid Valve Applications

Four Solenoid Valve Applications

A solenoid valve is a type of electromechanical device used to control fluid flow. The basic components include a sleeve to contain a plunger-type actuator, the actuator cylinder, and an orifice. The actuator plugs the orifice during closed operation, and retracts from the orifice during open operation. An electric current controls the state of the plunger. The current flows through a coil wrapped around the sleeve, creating a magnetic field along the axis of the actuator. In the presence of the current, the actuator is in the active state. Without the current, the actuator returns to the inactive state. The inactive state is the normal state. A normally open valve does not close the port until current flows.

Solenoid Vavles

Engineers specify solenoid valves by the following parameters:

  • Current drain – the amount of current required to activate the actuator coil. A transistor can drive this coil in low current uses. For large current requirements, a relay can drive the solenoid. When possible, designers prefer a transistor for lower cost, longer life, and shorter switching times.
  • Cv factor – the factor that relates valve flow to port pressure in the valve. A Cv factor of 1 yields a flow of 1 gallon per minute for a pressure differential of 1 psi.
  • Flow Capacity – the fluid flow for a given set of pressure and temperature parameters.
  • Manual Stem – specified by designers to act as an actuator in failsafe systems.
  • Maximum Operating Pressure Differential (MOPD) – the maximum pressure in either the open or the closed states that allows the valve to operate without failure within specifications.
  • Minimum Operating Pressure Differential – the minimum pressure required to maintain the normal state of the valve.
  • Safe working Pressure — the maximum pressure that prevents valve damage. The main failure point of a solenoid valve is the seals. If the system operates the valve beyond the safe working pressure, the MTBF (mean time between failures) of the valve drops significantly, and repair requires seal replacement.


1. Evaporator Temperature Control

This is the first of several application examples that show the design considerations for solenoid valves in real-world applications. This example shows an evaporative coolant system that could be part of a refrigerator or a home air conditioning unit.

During the first design step, the engineer constructs a flow diagram layout. In this case, the diagram includes an evaporator, a compressor, and a receiver, connected in series. A liquid line solenoid valve regulates the input to the evaporator. As the valve remains open longer, the amount of heat extracted from the system increases.

Engineers must remember that a solenoid valve is not a linear switch. It is only a two-state device. This means that the control device, in this case, a thermostat, must only give either a full on or full-off output current. Designers often use hysteresis to prevent rapid state changes in the valve. Conversely, the designer must minimize the temperature hysteresis to a few degrees to save the refrigeration unit from wide temperature fluctuations.  Continue reading

How Project Planning Software Can Save A Business Big Bucks


Imagine having a business tool that can predict the future—sound crazy, doesn’t it? Project estimation software might not be a crystal ball, but it is a super powerful tool for developing and analyzing future projects. The high potential cost-savings offered by this software make it the single best thing a business can use in the project planning system; working without one is a risk no business should take.

What Is Project Estimation Software?

Project estimation software goes beyond the planning stage; it is used from the earliest stages of development up to the very end of any project. The first stage in using the software involves using custom or general templates to develop the overall project design; users enter specific data and utilize software tools to map out the overall plan. Once the plan is set out, the software analyzes the plan by using behavioral models, performance metrics, and by comparing it to similar project plans. Project planning software will then provide percentage based probabilities for all aspects of the project, including costs, time tables and how realistic goals are.

The reports produced by the software are available in charts, graphs, and other forms that display a working model of how the project will likely play out. Estimation software is also able generate alternate options for projects; users can input variables and trade-offs to get an idea of how different approaches or changes will work. Users are able to continue to use these tasks during the actual project, giving them up to the moment estimates and the ability to assess progress on the go. Continue reading

Brand Loyalty

Branding an Ecommerce Website

Most companies understand that branding is the most important part of marketing.  Many large companies organize their marketing departments by Brand Manager.  It is the manager’s responsibility to make sure that when a customer thinks of a general product, that they think of the company’s product, and develop an unbreakable association.

Brand management consists of advertising, a hook (or brand), and a superior product.  Advertising starts by creating demand in the mind of the customer.  The hook is a way for the customer to remember the product.  This can be the distinctive logo of a famous sports shoe or the talking lizard for a famous car insurance company.  Finally, the superior product seals the deal by attaching customer satisfaction to the hook.  This process leads the customer to associate the product with the hook, or brand.

Website Branding

Online marketing has introduced a new kind of branding to marketing: the website brand.  This goes beyond presenting the logo on a website, but additionally creates a link between the website itself and the product.  Bookstores were one of the first industries to utilize website branding.  National booksellers initially created websites as convenience sites for those that preferred to shop and make their purchases online.  Continue reading


Three Flawed Assumptions Regarding Social Media Marketing

There are a few fundamental assumptions about social media marketing which can lead to marketing mistakes on the part of businesses. There aren’t the only mistakes a marketing team might make but they are some of the most common. By identifying these assumptions early on you can avoid making costly mistakes when deploying marketing messages with the help of various social media websites.

1. Assuming social media marketing is easy

Social media is a global phenomenon. Facebook currently has more than 1.2 billion users; according to a 2012 survey conducted by MacWorld Facebook users average 15 hours and 33 minutes of account use each month. Part of what makes networks like Facebook so popular is how easy they are to use. Only minimal computer literacy is needed to create an account and start using it. Because using social media sites is so easy, many people assume that using social media for marketing purposes is similarly easy. This leads to the first pitfall of social media marketing. Sometimes it is better to just buy a few trade show displays at hit the trade show circuit.

Social media users desire fresh content on an on-going basis. They rely on the accounts they’ve networked with to provide that content. Those accounts can belong to friends and family and they can also belong to you, a marketer. Consistent account usage is necessary and fresh content needs to be ready to go on a regular basis. Don’t assign the task of managing a social media account to an inexperienced online marketer. Make sure that whoever has the task of managing your business’s social media account has the time, resources, and experience necessary to make the most of your business’s account. Continue reading
