This demonstration presents the results of a study addressing an issue that has constrained the effectiveness of wireless sensor network deployments to date, namely, connectivity. A physically compact, diversity antenna has been developed that is low in complexity and therefore suitably controlled using resource-limited wireless sensor hardware. Herein,(More)
Functional analyses of human and nonhuman anthropoid primate femoral neck structure have largely ignored the trabecular bone. We tested hypotheses regarding differences in the relative distribution and structural anisotropy of trabecular bone in the femoral neck of quadrupedal and climbing/suspensory anthropoids. We used high-resolution X-ray computed(More)
This work demonstrates the use of wireless sensor nodes to monitor time- and frequency-selective channel fading in the 2.4 GHz ISM band. Four distinct channel conditions are considered: (1) a static node experiencing little to no fade, (2) a static node experiencing severe, frequency-selective fading, (3) a static node, in a dynamic environment and (4) a(More)
