Engineers Develop Personal Robots – New Age

2019-01-30T09:34:32-07:00

Engineers Say Personal Robotics Will Become an Important New Category in Family Lives  I have the idea of a “sociable” robot—one that people can have relatively natural interactions with—has been the lore of science fiction for decades. From Lost in Space to Star Wars to WallE and beyond, interactive robotic machines have been the stuff of our creative imagination for some time. In 2019, however, I believe we will start to see more practical implementations of personal robotics devices from several major tech vendors. While several companies have tried, and failed to bring personal robotics http://glewengineering.com/robotics-semiconductor-industry-prepares-for-450mm-wafers-part-2/the mainstream in the recent past, I believe several technologies and concepts are coming together to make the potential more viable this year. First, from [...]

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

2019-01-08T14:43:20-07:00

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

2018-10-26T09:39:38-07:00

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 !

2018-10-10T09:50:13-07:00

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

2018-09-25T15:38:05-07:00

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

2018-09-04T12:40:22-07:00

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 [...]

Semiconductor Worldwide: Samsung Takes Over

2018-06-22T11:44:20-07:00

Samsung topples Intel as top dog semiconductor market share  Gartner beancounters say price rises driven by memory shortages propelled Samsung into the lead based on semiconductor vendor revenue, vaulting past Intel and its CPUs. The largest memory supplier, Samsung Electronics, gained the most semiconductor market share and took the No. 1 position from Intel – the first time Intel has been toppled since 1992. Memory accounted for more than two-thirds of all semiconductor revenue growth in 2017, and became the largest semiconductor category.  DRAM prices rose 44 per cent from 2016 to 2017, and NAND flash prices went up 17 per cent year-over-year for the first time.
