  • Charge-coupled devices - A new approach to MIS device structures

    Recent advances in materials and processing have resulted in a new class of information-handling structure-the charge-coupled device. This three-layer structure creates and stores minority carriers, or their absence, in potential wells near the surface of the semiconductor. The minority carriers move from under one electrode to a closely adjacent electrode on the same substrate when a more negativ... View full abstract»

    This article summarizes the ideas that are being actively discussed for use in mobile radio and, in particular, how they apply to the new 900-MHz region assigned to the Land Mobile Radio Services category. Over the next decade some of these methods will prove out and others will probably fall by the wayside. It is clear, however, that some new techniques will be necessary if mobile radio is to con...

    An electric utility system is predicated to be in one of four possible states: normal, alert, emergency, or restorative. Examination of these states and the structure of the system's operating problems has led to a multilevel, multicomputer approach involving computers at various action centers interconnected by data links. Within the hierarchical computer arrangement, a four-step approach of moni... View full abstract»

    Historically the national goals of the United States have depended to a large extent on its science and technology. Now the character of this dependence is changing in light of the increasing emphasis on societal problems. The nature of these problems is discussed and needed actions delineated. It is concluded that the most critical areas in which progress is necessary are in the formulation of ob... View full abstract»

    Experiments with both long, continuous tones and short, transient tones have shown that the human ear is insensitive to relative phase differences between fundamentals and overtones. Short notes from a piano and from a drum are studied here to show that the phase requirement for music reproduction is that the group velocity of the system be constant in the relatively narrow regions surrounding the...

    According to the ECPD definition, engineering involves the use of the forces and materials of nature for the benefit of mankind. Unfortunately, in the course of their daily work engineers may forget to question whether their technological developments really will be a boon to society, and experience has shown that too often quite the reverse proves to be true. If the engineer of the future is to b... View full abstract»
