UAVs, also referred to as drones, are aerial vehicles without a human pilot on board. The vehicle is controlled either autonomously by an onboard computer or by a remote control from the ground or on another vehicle. UAVs range in size. Large UAVs are used for tactical missions and are powered by internal combustion engines. Small electric powered UAVs are primarily used for military and defense applications and are driven by electric motors. Without combustion, these electric powered UAVs are quiet and more suitable for spy missions. Also, there has been increased interest in the usage of UAVs for commercial applications such as aerial photography, agriculture, 3D mapping, and wildlife protection.

Visible and near-infrared light interact via absorption and scattering with biomolecules, and a number of diagnostic tools based upon these interactions have been developed to indicate pathophysiological states and normal and diseased tissue. Additionally, the cyclic nature of these absorption or scattering events, such as those arising from cardiovascular or pulmonary physiology, has recently been shown to indicate trauma and cardiovascular status. The most commonly encountered diffuse optical technique is pulse oximetry, a form of photoplethysmography (PPG), where the distinct absorption behavior of oxygenation and non-oxygenation hemoglobin molecules forms a basis for determining arterial blood O2 saturation levels (SpO2). New analysis algorithms have shown that PPG can be used to indicate a variety of physiological conditions beyond hypoxic hypoxemia (i.e., low SpO2) including noncompressible hemorrhage, a condition notoriously difficult to diagnose without CT or MRI capabilities, and cardiac output, a variable difficult to measure in real time noninvasively. With support from the FY12 Biomedical Initiative Line, we embarked on a size, weight, and power (SWaP) analysis of PPG sensors, and collaborated with Professors Ki Chon and Yitzhak Mendelson from Worcester Polytechnic Institute to build a prototype ultra-low SWaP sensor. This report gives background and motivation for why PPG sensing is an important physiological modality, and details on the SWaP analysis and prototype development.

Use of electronic alerts in clinical practice has had mixed effects on providers' prescribing practices. Little research has explored the use of electronic alerts for improving screening practices. New York City has one of the highest rates of HIV in the United States. Recent New York State legislation requires healthcare providers to offer an HIV test to patients aged 13-64 years during a clinical encounter. Adhering to this requirement is particularly challenging in emergency department (ED) settings, which are frequently overcrowded and under-resourced. The purpose of this study was to evaluate the effect of an electronic "hard-stop " alert on HIV testing rates in the ED. Approximately four months of data were reviewed before and after the implementation of the alert. We found that use of the electronic alert significantly increased documentation of offering an HIV test (O.R. = 267.27, p＜0.001) and resulted in a significant increase in HIV testing. Findings from this study add to the current knowledge about the use of electronic alerts for improving disease screening.
