Dual Purpose Upper and Lower Limb Rehabilitation Robot
BackgroundThere are 800,000 new cases of stroke in the United States and Canada each year. In cases of stroke, it is common for the upper and lower limbs to become weakened or paralyzed. Robotic rehabilitation systems have been developed to assist in the delivery of movement therapy to both the upper or lower extremities to maximize return of function...

Biopsy Needle System to Prevent P. acnes Contamination
BackgroundInfections are a potentially devastating complication of any surgery. Amongst the most devastating are post-surgical joint infections caused by Propionibacterium acnes (P. acnes), now considered the major microbial cause of surgical implant failures. Without early diagnosis and intervention, these infections result in joint tissue necrosis...

Copper-based photovoltaic nanocrystals for thin-film solar cells
IntroductionIncreased environmental awareness promoted many countries to adopt renewable energy as the new power source. Solar energy tapped through photovoltaic (PV) technology has become the widely accepted source of power generation, as it operation generates no pollution, and no greenhouse gas emissions. Improving efficiency while reducing cost...

Sample Collection, Annotation, Archiving, Analysis and Distribution System (SCAAAD)
BackgroundCurrent data collection and archiving methods are time-consuming and error-prone. Field scientists and technicians must carry a wide variety of sampling devices that inherently lack the ability to communicate with each other - often relying on a pen-and-paper system of recording and annotation. Further, when they exit the field and return...

Biological Nutrient Removal by Modified MBR System
Background:In response to increasingly stringent effluent nutrient criteria resulting from deteriorating surface water quality, biological nutrient removal (BNR) processes have become increasingly popular. In BNR processes, nitrogen and phosphorus can be removed simultaneously. These BNR processes employ a combination of anaerobic, anoxic and aerobic...

A Magneto-Rheological-Based Actuation System
Background:With current means of actuation, very few options exist that provide multiple degrees of freedom (DOF) and move independently without the addition of multiple motors. For instance, conventional means of safely actuating robotic devices involve the use of specially modified servo motors at each joint to control motion. In most applications...
