Ultrasound is one of the leading medical imaging modalities because it is safe, noninvasive, portable, easy to use, relatively inexpensive and displays images in real-time. Due to its real-time nature, an ultrasound machine must be able to process its incoming data quickly. High computational and throughput requirements in modern ultrasound machines have(More)
Compared with a single platform, cooperative autonomous unmanned aerial vehicles (UAVs) offer efficiency and robustness in performing complex tasks. Focusing on ground mobile targets that intermittently emit radio frequency signals, this paper presents a decentralized control architecture for multiple UAVs, equipped only with rudimentary sensors, to search,(More)
In this paper, we present a comparative study that evaluates the merit of cooperative unmanned aerial sensor systems against that of a single system with equivalent capabilities. The motivation for our study stems from the current lack of theoretical and empirical work that shows the effectiveness of multiple cooperative unmanned vehicles (UAVs) over the(More)
In this paper we propose a novel cooperation control method for multiple unmanned aerial vehicles (UAVs) to search, detect, and locate ground targets. We assume that our UAVs are only equipped with rudimentary angle of arrival sensors and the ground targets are mobile radio frequency (RF) emitters. In addition to the mobility, we assume our targets emit(More)
In this paper, we present a control architecture that allows multiple Unmanned Aerial Vehicles (UAVs) to cooperatively detect mobile RF (Radio Frequency) emitting ground targets. The architecture is developed under the premise that UAVs are controlled as a distributed system. The distributed system-based technique maximizes the search and detection(More)
We describe the design of an anthropomorphic robot head intended as a research platform for studying autonomously learning active vision systems. The robot head closely mimics the major degrees of freedom of the human neck/eye apparatus and allows a number of facial expressions. We show that our robot head can shift its direction of gaze at speeds which(More)
Families of critically ill infants in the neonatal intensive care unit may be placed in the emotionally charged position of making treatment decisions about their infants, including the withholding of medical treatment. Some families, unable to deal with these issues, cope through a harmful form of religious denial; the eternal belief in a miracle. This(More)
