Abstract: A system for reconstruction of an explosion blast loading on a subject can include at least two pressure sensors and a computing system configured to: receive sensor data from the at least two pressure sensors, the sensor data being generated in response to an explosion blast wave; compute an explosion location and explosive charge mass of an explosive that caused the explosion blast wave based on the sensor data; and compute explosion blast loading on a subject from the explosion location and explosive charge mass. The pressure sensors can be configured as wearable pressure sensors or on equipment. The computing of the explosion location and explosive charge mass includes processing the sensor data through an inverse problem solver (IPS); and/or the computing of the explosion blast loading on the subject includes simulating the explosion blast wave with a forward problem solver (FPS).

Abstract: Accurate characterization of microelectromechanical systems (MEMS) geometry is critical for device design and simulation, for material property extraction, and for post-fabrication trimming. According to the present embodiment, a method for characterizing parameters describing MEMS structures resulting from the fabrication process or process variations is presented. According to the prefered embodiment, experimentally obtained natural frequencies are compared with numerical simulations to identify unknown values of structural parameters or parameter variations. Further, the prefered embodiment teaches how electrostatically-driven laterally resonant comb-drive MEMS test structures with prescribed changes in spring width are used to characterize systematic variations in process offsets and sidewall angles. The disclosed technique is both in-situ and non-destructive.

Abstract: A fluid property sensor includes a substrate having a first electrode thereon, and a flexible member adjacent the substrate and the first electrode wherein the flexible member includes a second electrode. A signal generator generates a predetermined electrical signal across the first and second electrodes so that an electrostatic force is generated between the first and second electrodes and so that said flexible member deflects a predetermined distance. A measuring circuit measures an interval of time between the generation of the predetermined electrical signal and the deflection of the flexible member to the predetermined distance and determines a property of a fluid adjacent the flexible member based on the interval of time. For example, the sensor can be used to determine a viscosity of the fluid. Alternately, the fluid can be a compressible gas, and the sensor can be used to determine a pressure of the gas. Related methods are also discussed.

Abstract: An insect containing test apparatus which is applied to a skin region of a est subject includes a rectangular slide and test cage made of a clear, autoclavable polycarbonate plastic. The test cage is injection molded to a generally rectangular shape and includes a peripheral flange extending outwardly from sides at an open top. A screen member covering the open top is then heat pressed onto this flange. Test holes are also punched into the bottom the test cage. During injection molding, U-shaped channels along each respective longitudinal side adjacent the bottom are also provided to receive the slide so that the slide is selectively moved to cover and uncover the test holes in the bottom.
