Additional information for ???TREMOR: A Wireless, MEMS Accelerograph for Dense Arrays??? (Evans et al., 2003)

[摘要] The length of Evans et al. (2003) necessitated transfer of several less germane sections to this alternate forum to meet that venue?s needs. These sections include a description of the development of Figure 1, the plot of spatial variability so critical to the argument for dense arrays of strong-motion instruments; the description of the rapid, integer, computational method for PGV used in the TREMOR instrument (the Oakland instrument, the commercial prototype, and the commercial instrument); siting methods and strategies used for Class B TREMOR instruments and those that can be used for Class C instruments to preserve the cost advantages of such systems; and some general discussion of MEMS accelerometers, including a comparative Table with representative examples of Class A, B and C MEMS devices. (?MEMS? means ?Micro-ElectroMechanical? Systems??micromachined? sensors, generally of silicon. Classes A, B, and C are defined in Table 1.)
