摘要： A sweep sensor may include a signal source, a propagation medium, and a detector. By transmitting an interrogating signal from the signal source into the propagation medium, detectable disturbances along the medium can physically alter the characteristics of the medium, which may cause a measurable change in the backscattered signal at the detector. Based on the change, it may be possible to locate the geographic origins of the physical disturbances along the propagation medium, or to determine the nature of the disturbances, or both. For example, it is generally possible to estimate the approximate distance between the detector and the disturbance given the time required to obtain the backscattered signal and the velocity of the signal source in the propagation medium. Further, in some embodiments, it is possible to quantify the amount of disturbance.

摘要： Integrated circuits including a ferroelectric memory cell and methods for manufacturing the same. One embodiment of the memory cells include three main layers: a first oxide ferroelectric layer, a second oxide anti-ferroelectric layer, and a covering layer. The ferroelectric material of the first and second oxides include as main components oxygen and any of the group containing Hf, Zr, and (Hf, Zr).
