Testing device for verifying the performance of digital recorders

Test device, consisting of a pulse generator section and a manual program section, checks and calibrates digital recorder-printers. It is adaptable to other recorder configurations

The graphic user interface of the AudioGraph Recorder (PC version) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University

With the popularity of the use of computers and the development of the Internet, many multimedia-authoring systems have been developed for computer-based teaching and learning. This is playing an increasingly important role in education. One authoring system is the AudioGraph project developed at Massey university of N.Z., which have been developed for recording audio-graphic presentation material for publication in an html reference environment, i.e. "on the web". One of the tools in the AudioGraph project is the AudioGraph Recorder, which is a Macintosh application for recording or authoring web-based multimedia presentations. Due to the success of the publication of the AudioGraph application and the need of PC users, an AudioGraph Recorder for the PCs is required. This project is about the porting of the AudioGraph Recorder from the Macintosh platform to the PC platform. First this project report explains the functionality of the AudioGraph Recoder (the Macintosh version), especially how the end users interact with the interface of the AudioGraph Recorder, and the corresponding state changes of the controls in the interface. Then the report compares the development tools used in both platforms. The Macintosh version of the AudioGraph Recorder has been developed with the PowerPlant framework in CodeWarrior environment, but the PC version uses MFC framework in Visual C++ 6.0. This report also describes in detail how the interface of the AudioGraph Recorder application was constructed with the MFC, and implementation of some functionality of the application. At the same time some internals of the MFC framework are discussed

Ultrasonic scanning system for in-place inspection of brazed-tube joints

System detects defects of .051 cm in diameter and larger. System incorporates scanning head assembly including boot enclosed transducer, slip ring assembly, drive mechanism, and servotransmitter. Ultrasonic flaw detector, prototype recorder, and special recorder complete system

Run numbering system for use with data recorders

Run numbering identification system provides a permanent identification on the recorder traces of data runs. It automatically enters, by pulse coding, the number of the current data run on the recorder trace. The system uses a keyboard, registers, converters, amplifiers, and a pulse generator

Technique for strip chart recorder time notation

Single recorder channel helps determine the time an event is recorded on the readout of a strip chart recorder. It presents hours, tens of minutes, and minutes by a unique method of time increment identification. This facilitates recording timing marks

Remote lightning monitor system

An apparatus for monitoring, analyzing and accurately determining the value of peak current, the peak rate of change in current with respect to time and the rise time of the electrical currents generated in an electrical conductive mast that is located in the vicinity where lightning is to be monitored is described. The apparatus includes an electrical coil for sensing the change in current flowing through the mast and generating a voltage responsive. An on-site recorder and a recorder control system records the voltages produced responsive to lightning strikes and converts the voltage to digital signals for being transmitted back to the remote command station responsive to command signals. The recorder and the recorder control system are carried within an RFI proof environmental housing into which the command signals are fed by means of a fiber optic cable so as to minimize electrical interference

A solid-state digital temperature recorder for space use

A solid-state, digital, temperature recorder has been developed for use in space experiments. The recorder is completely self-contained and includes a temperature sensor; all necessary electronics for signal conditioning, processing, storing, control and timing; and a battery power supply. No electrical interfacing with the particular spacecraft on which the unit is used is required. The recorder is small, light, and sturdy, and has no moving parts. It uses only biocompatible materials and has passed vibration and shock spaceflight qualification tests. The unit is capable of storing 2048, -10 to +45 C, 8-bit temperature measurements taken at intervals selectable by factors of 2 from 1.875 to 240 min; data can be retained for at least 6 months. The basic recorder can be simplified to accommodate a variety of applications by adding memory to allow more data to be recorded, by changing the front end to permit measurements other than temperature to be made, and by using different batteries to realize various operating periods. Stored flight data are read out from the recorder by means of a ground read-out unit

An improved magnetic tape recorder

Magnetic tape recorder employs a single capstan for simultaneously driving the supply and take-up reels in such a manner that the tape passing between the reels is kept under a predetermined constant tension. This recorder operates with little power and is sufficiently rugged to withstand the severe stresses encountered in high-altitude balloon flight tests
