Electronics technology

While over the last 40 years microelectronic integrated circuits based predominantly on silicon technology have made possible our current capabilities in everything from computers and phones to appliances and toys, even greater opportunities would exist if the circuits could be made more lightweight,

Note These sources do not include the response time of the detector sensor and detector electronics as, today, employing modern electronic technology, such sources of dispersion have been rendered virtually picayune.)... 

Portable electronic manufacturers had the foresight to realize that battery technology was not keeping up with innovation in electronic technology, and it probably never would. To satisfy consumer demand for smaller and more powerful electronic devices that could go a longer time between charges, improvements in the energy efficiency of the devices themselves were required. 

The cost premium for a motor equipped with speed control can be substantial, sometimes costing twice that of a single-speed motor. But the energy savings from speed control can be substantial, especially for fan and pump systems. Electronic adjustable speed drives continue to become more attractive because the costs of microelectronics and power electronics technologies continue to fall as performance and energy efficiency improve. 

As the world s population increases, economic affluence is also increasing in many regions. Affluence usually means more business providing more goods and seiwices more homes and business with more climate control more use of appliances and electronic technology in homes and businesses and more miles logged by more automobiles, trucks, trains, and air-... 

Carbon is central to life and natural intelligence. Silicon and germanium are central to electronic technology and artificial intelligence (Fig. 14.28). The unique properties of Group 14/IV elements make both types of intelligence possible. The half-filled valence shell of these elements gives them special properties that straddle...

Oxides play many roles in modem electronic technology from insulators which can be used as capacitors, such as the perovskite BaTiOs, to the superconductors, of which the prototype was also a perovskite, Lao.sSro CutT A, where the value of x is a function of the temperature cycle and oxygen pressure which were used in the preparation of the material. Clearly the chemical difference between these two materials is that the capacitor production does not require oxygen partial pressure control as is the case in the superconductor. Intermediate between these extremes of electrical conduction are many semiconducting materials which are used as magnetic ferrites or fuel cell electrodes. The electrical properties of the semiconductors depend on the presence of transition metal ions which can be in two valence states, and the conduction mechanism involves the transfer of electrons or positive holes from one ion to another of the same species. The production problem associated with this behaviour arises from the fact that the relative concentration of each valence state depends on both the temperature and the oxygen partial pressure of the atmosphere. 

Most electronic technology systems use digital electronics in conjunction with microcomputer technology to allow the instrumentation user to calibrate and troubleshoot the instrumentation from either a local or remote location. This capability is commonly referred to as "Smart" electronic technology.
