Continuous tape recording of the electrocardiogram was carried out on 25 patients with sinus bradycardia or sinoatrial block. A 72-hour record was made on each fully ambulant patient, by a miniature portable tape recorder and the tapes processed with automatic dysrhythmia detection. A high incidence of slow and fast sinaatrial dysrhythmias was discovered and brief episodes of atrial tachydysrhy...

In this paper we will discuss advanced search functions for multimedia data produced by presentation. Such multimedia data consist of video of the speaker and slides used for explanation. In conventional systems, during playback these two components are synchronized and the presentation is played like video tape recorder. Basic functions are play, fast-play, skip, rewind and go-to-the previous-...

An EPLD based low cost transient recorder of video signal bandwidth (sampling rate 25MHz) is presented. It will be used to record and replay video signals. These video signals are handled by a video processing unit, under construction in a VHDL environment. The main advantage of this self made transient recorder is that the video signal processing device, which is under construction in a VHDL e...

The study of walking and other dynamic behaviour patterns has challenged the experimental ingenuity of researchers since Muybridge first demonstrated in a series of still pictures that galloping horses raise all four legs from the ground at once. The use of moving film improves the situation but still suffers from a fundamental disadvantage in the time required to process and analyse the change...

A portable digital recorder with event-triggering capability has been designed, and four have been constructed and field tested. The design was based on that used for over 2 years in ocean bottom seismic capsules. The outputs of as many as four seismometers are amplified, filtered, and digitized continuously at 64, 128,256, or 512 total samples per secdnd. The digital data are mixed with a time...
