This article presents procedures for modifying a hand held computer or personal digital assistant (PDA) into a versatile device functioning as an electronic stethoscope for fetal monitoring. Along with functioning as an electronic stethoscope, a PDA can provide a useful information source for a medical trainee. Feedback from medical students, residents and interns suggests the device is well ac...

Paper biosensors: an origami sensor is printed on a single piece of paper, folded into a three-dimensional fluidic device, and encapsulated by thermal lamination. Aptamer is trapped in the fluidic channel, where it binds to the target and releases an enzyme to generate a signal. The device is read out using a digital multimeter.

The new wireless communication standard UMTS applies an advanced dual-mode channel coding scheme. In this contribution we investigate the feasibility of implementing the algorithm on a digital signal processor device and the implication upon the processor architecture. Starting with a base architecture which allows for scalability and customization we derive new system parameters and compare th...

This paper summarizes our environment-image/videosupported collaboration technologies developed in the past several years. These technologies use environment images and videos as active interfaces and use visual cues in these images and videos to orient device controls, annotations and other information access. By using visual cues in various interfaces, we expect to make the control interface ...

An objective of our work is to find more systematic methods of designing and implementing real-time device drivers for embedded systems. As part of this objective, we answer the question “what is the best sampling rate to use for reading data from sensors that provide continuous data?” Our experiences in answering this question for digital switch and analog sensor inputs is described. We first ...
