Abstract:

A preliminary paper design of a portable data recorder has been completed and its projected performance analyzed. The recorder is a hand-held, battery-powered device that can record on a single tape cassette both analog voice and digital keyboard data. In addition, it provides visual and audible prompts for the operator as well as data playback and editing capabilities. Recorded digital data can be directly electronically entered into a computer data base. Since the device is controlled by a microprocessor, it is very versatile in nature and, through simple programming software changes, can be adapted for use in a great variety of data-gathering applications. A preliminary design of the major components of the device, which include a microprocessor, keyboard, memory, tape-cassette drive, alphanumeric display, and power supply, is discussed.
