David J. Brady; ILLINOIS UNIV CHAMPAIGN
|
| Radical improvements in electronic sensor and processor capabilities in the past decade have destabilized basic definitions of imaging in general and three-dimensional imaging in particular. Conventionally, imaging refers to analog focal or holographic systems that integrate information acquisition and processing. Increasingly aggressive digital processing, however, diminishes the processing role in the sensor head. Particularly in sensor arrays, there is often no need for a well-formed 'image' in analog space. The ... |

| U.S. Army helicopters used to provide aeromedical transport are extremely noisy (105 dB) and this prevents auscultation with current generation stethoscopes. Four stethoscopes were tested in simulated helicopter noise at 70 to 100 dB to determine the detection threshold of a normal heart and breath sound. They were unable to detect physiological sounds in high noise but they did differ in performance (p < 0.001); the best being the acoustic, ... |

| Many satellites are an integrated collection of sensors and actuators that require dedicated real-time control. For single processor systems, additional sensors require an increase in computing power and speed to provide the multi-tasking capability needed to service each sensor. Faster processors cost more and consume more power, which taxes a satellite's power resources and may lead to shorter satellite lifetimes. An alternative design approach is a distributed network of small ... |
