Corrective Writing Instrument for Persons Affected by Tremors

Involuntary tremors affect approximately 12 million people in the United States and are primarily caused by ParkinsonÍs disease (PD), essential tremor (ET), and dystonia. Tremors are typically observed in the hands and are thus the main source of difficulties faced by patients while performing common daily activities such as eating and writing. Affordances for handwriting, … See More

Microfluidic Separation of Cells against Multiple Markers

Endothelial progenitor cells (EPCs) have the ability to repair damaged blood vessels and therefore are useful as precursors in the in vitro cultivation of vascular grafts. There is a need to sequester these cells from whole blood, an inherently heterogeneous mixture. The ability to isolate these rare cells from a complex blood suspension requires a … See More

Environmental Data Analysis, GIS Mapping, and Groundwater Modeling in the North Coast Karst Aquifer of Puerto Rico

The goal of the PROTECT NIEHS SRP Center is to evaluate exposure to groundwater contamination through karst formations in Northern Puerto Rico and assess the potential impact of said exposure on public health. This will be achieved through integrated analytical, mechanistic, epidemiology and fate-transport studies, along with a centralized, indexed data repository. Prediction of contaminant … See More

Pavement Condition Assessment Using Vehicle-Mounted Multisensor Data Fusion

Cities use pavement management systems to ensure their pavement networks are kept in serviceable condition in a cost effective way. These systems rely on condition surveys that provide a numerical condition rating for every street. Conventional condition surveys require a rigorous in-field inspection by trained experts, which is time consuming, unsafe for inspectors, subjective, and … See More

VOTERS System Integration: A mobile heterogeneous sensor system

Sensing challenges in roaming sensor systems stem from the physical process to be monitored. Depending on physical process to be monitored; more than one sensor type may be needed to gain a complete view of the measured process. As an example to assess a road surface status a camera image showing surface cracks may need … See More

Optimization of Healthcare Delivery Regional Network Topology

Given the high costs of healthcare coupled with a focus on access and preventive health, many healthcare systems are engaged in macro-level planning of their overall network topology, care location, market expansion, and merger strategies. Numerous examples exist across the U.S. We have developed a set of network design tools to facilitate these complex decision-making … See More
