Biofidelic Model of Human Cranium and Intracranial Contents

INTRODUCTION Brain injury researchers and human protection engineers need a tool to investigate how mechanical loading influences brain motion, strain and displacement. A new test object must be able to quantify metrics of soft-tissue/brain tissue disruption from head injury. Current testing for head injury is crash test dummies. This model determines...

Soft Actuators with Stiffness and Shape Modulation

Executive SummaryAccurate and stable robotic systems have traditionally been constructed using rigid materials. However, soft and deformable structures have seen growing interest and application in recent years because they tend to outperform rigid systems. Soft robotics is a subfield that utilizes soft and deformable features, similar to ones found...

Chemical Efficacy, Environmental Safety, and Operational Design Improvements for the SandSprayer "Spreader Apparatus for Sand Based Formulations" (Patent No. 8,028,928)

Executive SummaryCurrently, as a part of turfgrass installation and maintenance, topdressing sand and active ingredients (fungicide/growth regulators) are applied sequentially, requiring two passes over the turf. Carrying out these processes separately requires additional time to make two identical passes, leads to spray drift when spraying chemicals,...

Quasi-Static Self-Powering, Sensing, and Data Logging

Executive SummarySlowly acting events can be very difficult to sense, especially for self-powered sensors. Most sensors require an external energy source in order to detect the desired property and report results. For some applications however, a self-powered sensor is desirable that uses energy from the object being sensed in order to record the data....
