Augmented reality: an application of heads-up display technology to manual manufacturing processes

The authors describe the design and prototyping steps they have taken toward the implementation of a heads-up, see-through, head-mounted display (HUDset). Combined with head pos...

Simulation and testing of a graded negative index of refraction lens

A gradient index (GRIN) lens using a negative index of refraction material (NIM) has been designed and tested. The GRIN lens was fabricated using a NIM slab with a variable inde...

Relative Sensing Networks: Observability, Estimation, and the Control Structure

In this paper we consider various structural aspects of estimation and control over relative sensing networks. We first expand on our earlier characterization of equivalent sens...
