Micromachined Ultrasound-Based Proximity Sensors

Micromachined Ultrasound-Based Proximity Sensors

Micromachined Ultrasound-Based Proximity Sensors presents a packaged ultrasound microsystem for object detection and distance metering based on micromachined silicon transducer elements. It describes the characterization, optimization and the long-term stability of silicon membrane resonators as well as appropriate packaging for ultrasound microsystems. Micromachined Ultrasound-Based Proximity Sensors describes a cost-effective approach to the realization of a micro electro mechanical system (MEMS). The micromachined silicon transducer elements were fabricated using industrial IC technology combined with standard silicon micromachining techniques. Additionally, this approach allows the cointegration of the driving and read-out circuitry. To ensure the industrial applicability of the fabricated transducer elements intensive long-term stability and reliability tests were performed under various environmental conditions such as high temperature and humidity. Great effort was undertaken to investigate the packaging and housing of the ultrasound system, which mainly determine the success or failure of an industrial microsystem. A low-stress mounting of the transducer element minimizes thermomechanical stress influences. The developed housing not only protects the silicon chip but also improves the acoustic performance of the transducer elements. The developed ultrasound proximity sensor system can determine object distances up to 10 cm with an accuracy of better than 0.8 mm. Micromachined Ultrasound-Based Proximity Sensors will be of interest to MEMS researchers as well as those involved in solid-state sensor development.

Social Psychology and Dysfunctional Behavior

Social Psychology and Dysfunctional Behavior

A colleague recently recounted a conversation she had had with a group of graduate students. For reasons that she cannot recall, the discussion had turned to the topic of "old-fashioned" ideas in psychology-perspectives and beliefs that had once enjoyed widespread support but that are now regarded as quaint curiosities. The students racked their brains to outdo one ofthe historical trivia of psychology: Le Bon's another with their knowledge fascination with the "group mind," Mesmer's theory of animal magnetism, the short-lived popularity of "moral therapy," Descartes' belief that erec­ tions are maintained by air from the lungs, and so on. When it came his tum to contribute to the discussion, one student brought up an enigmatic journal he had seen in the library stacks: the Journal of Abnormal and Social Psychology. He thought that the inclusion of abnormal and social psychology within the covers of a single journal seemed an odd combination, and he wondered aloud what sort of historical quirk had led psychologists of an earlier generation to regard these two fields as somehow related. Our colleague then asked her students if they had any ideas about how such an odd combination had found its way into a single journal.

You just can't make this stuff up. The best Hollywood script writers are no match for the odd turns of fate, the twists of fortune, and the dramatic events that actually happen in real life. Here are real conspiracies, historical legends, mysterious murders, social scandals, and a horse thief who quite literally gets caught with his pants down.Inquests are often forgotten as a historical source, frequently lost in the glow of subsequent and more sensational public trials. Yet because of how the system operates, they are many times the most immediate and timely reconstruction of the scene and event, especially in the historical period where they were frequently held over the body at the place the death occurred. Included are forty-six stories of the beginnings of forensics and death investigation in Fremont County, Wyoming, from 1885 to 1900.Sometimes justice is served, sometimes it goes astray. Presented inside before you, the jury, is the evidence as gathered, and the testimony as heard, to await your impartial decision as to the cause and manner of death of the forty-six bodies that now lie before you.

Haunted Noble County, Indiana

Haunted Noble County, Indiana

Noble County boasts small-town charm and attractions all year long. And ghosts. The county's only movie theater is patrolled by the well-known manager, who died in 1995. Two of the highest hills in the state are haunted, one after a hanging and another because of a murder immortalized by Indiana's poet laureate. The sprawling Kneipp Sanitarium received a visit from the Virgin Mary herself and became a battleground of good versus evil. Former residents of the county poor farm still roam the building. Then there's the "Thing in the Basement." Join authors and historians Mark and Emily Hunter as they tour the dark and spooky corners of Noble County.
