Apart from MPG, what’s a fair way to measure the efficiency of advanced technology vehicles?
X-Files fans, conspiracy theorists, and the tinfoil hat crowd were right all along! Sorta… In the 1950s, the US government really was building a flying saucer. But it didn’t involve little green men, human-alien hybrids, or David Duchovny; this isn’t what you’d call a "smoking gun."
The demand for better and more efficient power sources in the automotive industry has been a driving force behind research in battery technology, capacitor technology, and electronic power supply design. In order to utilize energy as efficiently as possible, automotive engineers began by reducing the gross weight of an automobile
The majority of motor-control designers are consistently and continuously looking for methods to improve efficiency while reducing system cost. These are the two main factors that are driving the efforts to improve existing motor designs and motor-control techniques. A good example of this trend is the Permanent Magnet Synchronous Motor (PMSM).
The automobile is changing and so, too, are the electronics that make them run. The most radical example is the plug-in electric vehicle (PEV) where a 300-400V Lithium-Ion (Li-Ion) battery replaces the gas tank
There are a number of technology trends that are profoundly changing how engineers are designing machines with motion control. Two among these stand out for their potential impact on cost, ease of assembly, and serviceability. These are the continual reduction of the size of the motion amplifier, and the advent of low cost, high-speed digital networks.
Although an increasing interest and use of Permanent Magnet Synchronous Motors (PMSM) can be observed during the last decade, the standard 3-phase Induction Motor (IM) is still the most widely used electrical motor. The simplest way to start an IM is to connect the motor directly to the 3-phase main supply.
An RF designer’s wish list for an ideal high frequency capacitor would include extremely high temperature stability, a sharp self resonance (high Q) free from harmonics, extremely tight capacitance tolerance, low ESR (equivalent S\series R\resistance), low ESL (equivalent series inductance), complete reproducibility
Young people with an interest in electronics still have a cornucopia of kits to start with. As a youngster I had a crystal radio that picked up several local stations I listened to with a small headphone. You can still buy crystal-radio kits and many cost under $20.
I want to take a look at PID loops and how they are typically handled in software. I'm going to contrast how the motor control folks do things vs. how the chemical industry folks do things. Now there are all kinds of things you can control with such a loop (in a motor control context).
The current state of healthcare today in the US is one which focuses upon cost containment, while at the same time, providing the advancements of modern technology to an aging population. Finding effective treatment methods at affordable levels, while at the same time providing patients with high quality care is certainly a tightrope act many healthcare providers walk.
Medical electronic assemblies have unique requirements that set them apart from other types of electronic devices, such as consumer electronic products. Often, thermal management issues must be anticipated in the design, and assemblers must conform to certain quality standards such as ISO 13485.
The medical market, while on the frontier of human sciences, has always been conservative and cautious when it comes to analyzing the market’s technology adoption rate. While the rest of the industrial and consumer markets were immersed in the potential of wireless connectivity, networking and the Internet, the medical market continued to build devices with tried and tested technology.
