An inexpensive interface is described that performs direct transfer of digitized data from the digital audio processor and video cassette recorder based data acquisition system designed by Bezanilla (1985, Biophys. J., 47:437-441) to an IBM PC/XT microcomputer. The FORTRAN callable software that drives this interface is capable of controlling the video cassette recorder and starting data collec...

In this paper, we propose an efficient scene change detection method for personal video recorder to provide users with several convenient functionalities such as the browsing, fast forward and skip-play of recorded videos. Since most of the current available PVRs have low-powered CPUs, the scene change detector should not be computationally expensive. We implement the scene change detection alg...

A volume angiography system for on-line computation of left ventricular angiograms has been developed utilizing a video disc recorder, a light-pen unit, and a digital computer. The video disc recorder allows for immediate replay and stop-motion of ventricular angiograms on a video monitor. The light-pen is used by a technician/physician operator to define the margins of the ventricular chamber ...

A portable device designed for in-field recording of biosignals is presented. The recorder is provided with three bipolar channels digitising at 200 Hz and lacks of interpretive intelligence. The captured data is send in real time via serial communication interface using AT commands, or stored in the internal memory for delayed transmission. Two operating modes are implemented: scheduled acquis...

In this study, a detailed description of development of a new novel bite force recorder (gnathodynamometer) using solid state components is vividly explained. This state of the art authenticated device can be used to assess the complex function of human bite force, which is the net resultant combination of functional response of various craniomandibular structures consisting of interrelated com...

A system is described for the conversion of a Beckman DU spectrophotometer to automatic recording-integrated densitometry. This system has also been applied to flow spectrophotometry with a wide-range monochromatic system substituted for the filter photometer of the Technic on AutoAnalyzer. A log converter is used which changes the impulse from linear to logarithmic and feeds this to the record...

Data logging capability of a previously developed self contained cough recorder using an accelerometer as the sensing element is improved by using a secure digital memory card for later retrieval on a computer. Firmware is developed to enhance the fimctionality of the cough recorder. Existing libraries are modified for increased write rates. Increased writing speed allows 8-bit sampling at rate...
