Part 2: Self-driving Cars Expand the Fight Over Airwaves

2018-11-26T09:53:05+00:00

Engineers Say Public is Hungry for More Wi-Fi Capacity, the telecom industry is looking to snatch control of underutilized airwaves reserved for the auto industry. But this is coming just as carmakers begin to make progress on developing and adopting technologies for connected and autonomous cars that currently rely on that spectrum. The Big Picture: Tech and telecom companies have been fighting for years over spectrum to support exploding demand for mobile services and smartphones. Automakers have had exclusive access to a band of spectrum for almost 20 years but haven't done much with it, prompting telecom providers to argue, "Use it or lose it." The Dilemma: Some safety advocates and automakers worry that commercial Wi-Fi will interfere [...]

Mechanical Engineers Say Proper Ventilation is Crucial for Your Small Business

2018-10-26T09:39:38+00:00

Engineers Explain How Good Ventilation Helps Your Business We’ll start with a fact that often startles people: (indoor air quality is a major health threat in the country).  According to the U.S. Environmental Protection Agency, the air quality inside buildings is often 3 to 4 times worse than the air outside. This goes against what most people think air pollution is like— fumes from cars and smoke stacks casting dark clouds over cities.  Heavy wall insulation, tightly fitted, non-opening windows ( Window Efficiency ), and commercial synthetic carpeting in modern buildings allows for the rapid build-up of contaminants inside without the chance to escape. Proper ventilation in your business that was designed by a licensed mechanical engineer(Licensed Mechanical Engineer ), is a key [...]

Mechanical Engineers Recommend Home Drainage – Winter Months are Coming !

2018-10-10T09:50:13+00:00

How Do Engineers Handle Rainwater? Engineers can help with proper fitting of gutters, or eaves troughs as they are called in some parts of the country. They are an important part of the drainage system around your house.  If yours are nonexistent, in poor condition, or improperly placed on your house, they could be causing problems and putting your home at risk of water damage. Gutters need to be installed properly so that they catch the water coming off your roof and channel it away from your house and its foundation.  Your eaves troughs should have a downward slope of 1/2 inch for every 10 feet of run to ensure they drain completely.  If your house is more than [...]

Engineers Develop Ways to Ventilate Your Home

2018-09-25T15:38:05+00:00

Why ventilate? For centuries homes weren’t ventilated, and they did all right, didn’t they? Why do we need to go to all this effort (and often considerable expense) to ventilate houses today?  Engineers have developed several reasons that ventilation is more important today than it was long ago. Most importantly, houses 100 years ago were leaky. Usually they didn’t have insulation in the walls, so fresh air could easily enter through all the gaps, cracks, and holes in the building envelope., the building materials used 100 years ago were mostly natural products that didn’t result in significant off gassing of volatile organic compounds (VOCs), formaldehyde, flame retardants, and other chemicals that are so prevalent in today’s building materials, furnishings, [...]

Engineers Test “CHP” – Combined Heat and Power

2018-09-04T12:40:22+00:00

Figure 1. Self Sufficient Home with Combined Heat and Power Combined Heat and Power (CHP) Engineers combined heat and power (CHP) systems, also known as cogeneration, generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but an approach to applying technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, which avoids the losses that would otherwise be incurred from separate generation of heat and power. While the conventional method of producing usable heat and power separately has a typical combined efficiency of 45 percent, CHP systems can operate at levels as high as 80 percent. Some micro-CHP technologies use mechanical engines, such as internal combustion [...]

  Material Scientist Ponder What to Do With Used EV Batteries  As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025.  This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements.  The price of cobalt has already risen by more than 80 per cent in 2018.   Most expert Material Scientists agree that a replacement hybrid car battery can range from $1,000 to more than $6,000.  The [...]

Engineering Advances: Degradation and Saving Electric Vehicle Batteries

2018-07-10T15:47:30+00:00

Degradation of EV Lithium Batteries  Battery degradation in Electric Vehicles (See Figure 1. to Right) leads to capacity fade, thereby shortening the vehicle’s possible range.  Patterns are beginning to emerge and provide valuable insight into EV battery capacity and lifetime.  Most drivers are retaining over 90% of original capacity Range Anxiety Some cars have a range of only 106 miles, equivalent to just over three times the average daily drive in the US. New Electric Vehicles are expected to have a range of up to 235 miles, a 220% increase, therefore, range is constantly improving to address consumer concerns. Charging an EV takes time, and unless you have fast in-home charging infrastructure or public charging infrastructure it will remain a barrier. [...]

NAND Flash – 11 Myths Still Floating Around

2018-06-27T16:21:57+00:00

Think You Know NAND Flash?  NAND flash has become the de facto memory standard in the years since Toshiba first introduced it almost three decades ago. However, many misconceptions remain to this day about its use. A wide variety of NAND flash-memory products are available, all with significantly different features and capabilities.    All NAND flash has the same interface. NAND flash, introduced by Toshiba more than 20 years ago, is available in both the asynchronous and toggle-mode interfaces. The original asynchronous interface is found mostly in lower-density devices (<32 Gb), while high-density NAND flash (≥64 Gb) is typically used in the toggle-mode interface.( http://glewengineering.com/tester-prober-interfaces-direct-probe-part-1/  UFS memory is primarily just for smartphones.
