BACKGROUND AND PURPOSE Despite advances in mechanical thrombolysis for acute stroke, recanalization rates remain approximately 50%-60%. Technologic improvements allowed safe intracranial delivery of stents. To study the feasibility of stent-assisted recanalization for acute stroke, we deployed self-expanding or balloon-mounted stents in 2- to 3.5-mm canine vessels acutely occluded with clot emb...

This study covers a self-powered wireless communication system that is powered using piezoelectric energy harvester (PEH) in shoe. The lead-zirconate-titanate (PZT) ceramic of the PEH was coated with UV resin, which (after curing under light) allowed it to withstand periodic pressure. designed simple structure and placed sole durability tested pushing tester its applicability shoes examined. Wi...

The ability to manipulate objects is fundamental to most virtual reality (VR) applications. A multitude of metaphors have been developed to facilitate object selection and manipulation [1], including virtual hand [2], which remains by far the most popular technique in this category. The utility of the virtual hand depends on the user’s ability to see it. Unfortunately, ensuring this is not alwa...

INTRODUCTION Although videos of surgical procedures are useful as an educational tool, the recording of trauma surgeries in emergency situations is difficult. We describe an inexpensive and practical shooting method using a commercially available head-mounted video camera. METHODS We used a ContourHD 1080p Helmet Camera (Contour Inc., Seattle, Washington, USA.). This small, self-contained vid...

The lack of image brightness is a common problem in optical see-through head-mounted displays (OST-HMD) where a beamsplitter is required to combine views from HMD image source and the direct-view of a real world scene. This problem is further aggregated in a headmounted projective display (HMPD) due to the fact that light passes through the beamsplitter multiple times. In this paper, we present...
