Book Description
Figures 1 and 2 are simplified block diagrams of the Passive Infrared Motion Sensor (PIMS). Figure 3 shows the location of the 17 beams of coverage within the 20 ft. x 30 ft. specified area when the optics are mounted at 7 ft. 4 inches. The system is a motion detector using transient changes in the infrared background, within specified velocities, to generate alarms. A long term infrared source would eventually blend into the overall noise background and not be detected indefinitely. A filter is used to prevent visable light from generating alarms. Since infrared detection is passive any number of units can be placed in a particular location without interference. Infrared detection becomes less sensitive when the background temperature approaches that of the target (human intruder). Some care must be taken upon installation that clutter such as rapidly heating pipes, windows or air ducts are not located within one or more beams. Due to the long time constants involved in processing frequencies around .1 Hz, it is necessary to allow a 5 minute warmup before alarms can be considered genuine. (Author).

Book Description
This second edition of An Introduction to Predictive Maintenance helps plant, process, maintenance and reliability managers and engineers to develop and implement a comprehensive maintenance management program, providing proven strategies for regularly monitoring critical process equipment and systems, predicting machine failures, and scheduling maintenance accordingly. Since the publication of the first edition in 1990, there have been many changes in both technology and methodology, including financial implications, the role of a maintenance organization, predictive maintenance techniques, various analyses, and maintenance of the program itself. This revision includes a complete update of the applicable chapters from the first edition as well as six additional chapters outlining the most recent information available. Having already been implemented and maintained successfully in hundreds of manufacturing and process plants worldwide, the practices detailed in this second edition of An Introduction to Predictive Maintenance will save plants and corporations, as well as U.S. industry as a whole, billions of dollars by minimizing unexpected equipment failures and its resultant high maintenance cost while increasing productivity. - A comprehensive introduction to a system of monitoring critical industrial equipment - Optimize the availability of process machinery and greatly reduce the cost of maintenance - Provides the means to improve product quality, productivity and profitability of manufacturing and production plants

Book Description
Here is unique and comprehensive coverage of modern seismic instrumentation, based on the authors’ practical experience of a quarter-century in seismology and geophysics. Their goal is to provide not only detailed information on the basics of seismic instruments but also to survey equipment on the market, blending this with only the amount of theory needed to understand the basic principles. Seismologists and technicians working with seismological instruments will find here the answers to their practical problems. Instrumentation in Earthquake Seismology is written to be understandable to the broad range of professionals working with seismological instruments and seismic data, whether students, engineers or seismologists. Whether installing seismic stations, networks and arrays, working and calibrating stationary or portable instruments, dealing with response information, or teaching about seismic instruments, professionals and academics now have a practical and authoritative sourcebook. Includes: SEISAN and SEISLOG software systems that are available from http://extras.springer.com and http://www.geo.uib.no/seismo/software/software.html
