This book deals with the challenge of exploiting ambient vibrational energy which can be used to power small and low-power electronic devices, e.g. wireless sensor nodes. Generally, particularly for low voltage amplitudes, low-loss rectification is required to achieve high conversion efficiency. In the special case of piezoelectric energy harvesting, pulsed charge extraction has the potential to extract more power compared to a single rectifier. For this purpose, a fully autonomous CMOS integrated interface circuit for piezoelectric generators which fulfills these requirements is presented. Due to these key properties enabling universal usage, other CMOS designers working in the field of energy harvesting will be encouraged to use some of the shown structures for their own implementations. The book is unique in the sense that it highlights the design process from scratch to the final chip. Hence, it gives the designer a comprehensive guide of how to (i) setup an appropriate harvester model to get realistic simulation results, (ii) design the integrated circuits for low power operation, (iii) setup a laboratory measurement environment in order to extensively characterize the chip in combination with the real harvester and finally, (iv) interpret the simulation/measurement results in order to improve the chip performance. Since the dimensions of all devices (transistors, resistors etc.) are given, readers and other designers can easily re-use the presented circuit concepts.

Life in a small town takes a dark turn when mysterious footage begins appearing on VHS cassettes at the local Video Hut Jeremy works at the Video Hut in Nevada, Iowa—a small town in the center of the state, the first “a” in Nevada pronounced “ay.” This is the late 1990s, and while the Hollywood Video in Ames poses an existential threat to Video Hut, there are still regular customers, a rush in the late afternoon. It’s good enough for Jeremy: It’s a job, quiet and predictable, and it gets him out of the house, where he lives with his dad and where they both try to avoid missing Mom, who died six years ago in a car wreck. But when a local schoolteacher comes in to return her copy of Targets—an old movie, starring Boris Karloff, one Jeremy himself had ordered for the store—she has an odd complaint: “There’s something on it,” she says, but doesn’t elaborate. Two days later, a different customer returns She’s All That, a new release, and complains that there’s something wrong with it: “There’s another movie on this tape.” Jeremy doesn’t want to be curious. But he takes a look and, indeed, in the middle of the movie the screen blinks dark for a moment and She’s All That is replaced by a black-and-white scene, shot in a barn, with only the faint sounds of someone breathing. Four minutes later, She’s All That is back. But there is something profoundly unsettling about that scene; Jeremy’s compelled to watch it three or four times. The scenes recorded onto Targets are similar, undoubtedly created by the same hand. Creepy. And the barn looks much like a barn just outside of town. There will be no ignoring the disturbing scenes on the videos. And all of a sudden, what had once been the placid, regular old Iowa fields and farmhouses now feels haunted and threatening, imbued with loss and instability and profound foreboding. For Jeremy, and all those around him, life will never be the same . . .

The complete illustrated story of the combine harvester. Accompanied by a wide variety of new colour photographs, this book will appeal to farm machinery enthusiasts and those interested in the development of modern industrial machinery.
